Patient Safety & Systems-Based Practice

Insurance models: Medicare, Medicaid, ACA, commercial

Clinical Overview and When to Suspect Insurance Coverage Issues

— Medicare — federal, age ≥65 or disability/ESRD/ALS

— Medicaid — joint federal-state, low-income (eligibility varies by state, especially post-ACA expansion)

— ACA Marketplace plans — private plans purchased on exchanges, often subsidized

— Commercial/employer-sponsored — private insurance, dominant under-65 coverage

— TRICARE/VA, IHS, CHIP — additional federal niches

— Vignette mentions cost as a barrier to filling prescriptions, adherence, or screening

— Patient is turning 65, retiring, losing job, getting divorced, or aging out at 26

— New diagnosis of ESRD, ALS, or SSDI approval (Medicare pathway)

— Pregnant patient or child needing coverage (Medicaid/CHIP)

— Undocumented patient needing care (emergency Medicaid only)

— Patient in donut hole, prior auth denial, or "step therapy" failure

US insurance is a patchwork of public and private payers, each with distinct eligibility, benefits, cost-sharing, and network rules that directly shape Step 3 management decisions

Major categories tested:

When to "suspect" insurance is the answer choice:

Step 3 frames insurance as a systems-based practice competency: choosing cost-effective generics, ordering covered preventive services, coordinating care within network, and using social work/case management appropriately

Board pearl: If a Step 3 stem mentions a patient skipping insulin, splitting pills, or missing follow-up because of cost, the best answer is rarely "counsel on adherence" — it is refer to social work / pharmacy assistance program / switch to covered generic / enroll in Medicaid or Marketplace

Recognize that EMTALA mandates stabilization regardless of insurance — never delay emergency care to verify coverage

Coverage status changes risk-adjusted outcomes: uninsured patients have worse cancer-stage at diagnosis, higher readmissions, and lower preventive service uptake — a recurring exam theme

Presentation Patterns and Key History — Who Has Which Plan

— 65-year-old retiree, or <65 with 24 months of SSDI, ESRD on dialysis, or ALS diagnosis (ALS and ESRD waive the 24-month wait)

— Parts: A (hospital, SNF, hospice, home health — premium-free if 40 quarters worked), B (outpatient, physician, DME, preventive — monthly premium), C (Medicare Advantage, private replacement), D (drugs)

— Original Medicare has no out-of-pocket maximum without Medigap supplement

— Low-income pregnant patient, child, disabled adult, or low-income adult in an expansion state (≤138% FPL)

— Covers long-term nursing home care (Medicare does NOT beyond 100 SNF days)

— Dual-eligibles ("Medi-Medi") — Medicare primary, Medicaid wraps cost-sharing and LTC

— Self-employed, early retiree (<65), young adult who aged off parental plan at 26, or worker without employer coverage

— Subsidies (premium tax credits) for 100–400% FPL (extended through 2025)

— Metal tiers: Bronze/Silver/Gold/Platinum — Silver carries cost-sharing reductions

— Working-age adult with HMO/PPO/HDHP; HDHP pairs with HSA

— COBRA continues employer plan 18 months after job loss at full premium

— "Are you taking your medications as prescribed?" — uncovers cost nonadherence

— Recent life events: job change, marriage, birth, age 26, age 65, disability onset → trigger special enrollment periods

Key history questions to ask in vignettes:

Key distinction: Medicare ≠ Medicaid. Medicare = age/disability, federal, uniform. Medicaid = income, state-variable, covers LTC and dental/vision in many states. Asking "which payer covers the nursing home stay?" — answer is almost always Medicaid, not Medicare

Structural Assessment — Parts, Tiers, and Network Architecture

— Part A: inpatient hospital, SNF up to 100 days (days 1–20 fully covered, 21–100 with copay, requires preceding 3-day inpatient stay), hospice, home health. Premium-free with sufficient work history

— Part B: outpatient visits, labs, DME, preventive services at no cost-sharing (mammogram, colonoscopy screening, AWV, vaccines via ACIP). Standard monthly premium, 20% coinsurance after deductible

— Part C (Medicare Advantage): private plans bundle A+B (±D), often HMO/PPO with network restrictions, may add dental/vision/gym

— Part D: outpatient prescription drugs; historical coverage gap ("donut hole") narrowed; Inflation Reduction Act caps insulin at $35/month and out-of-pocket drug spending at $2,000/year (2025)

— State-administered within federal rules; mandatory benefits include inpatient/outpatient, lab, x-ray, EPSDT for children, nursing facility, home health

— Optional benefits vary: dental, vision, PT, prescription drugs (all states currently cover Rx but technically optional)

— Bronze 60% / Silver 70% / Gold 80% / Platinum 90% actuarial value

— All cover 10 Essential Health Benefits including maternity, mental health, preventive, Rx

— Preventive services rated A/B by USPSTF must be covered with $0 cost-sharing — pivotal exam fact

— HMO — narrow network, PCP gatekeeper, referrals required

— PPO — broader, out-of-network allowed at higher cost

— EPO, POS, HDHP+HSA hybrids

Medicare anatomy (memorize cold):

Medicaid structure:

ACA plan tiers:

Commercial plan types:

Step 3 management: When a Medicare patient needs post-acute rehab, confirm a qualifying 3-day inpatient stay before SNF transfer — observation status does NOT count, a classic transition-of-care pitfall causing surprise bills

Diagnostic Workup — Identifying Coverage Gaps and Eligibility

— Confirm current coverage status (uninsured, underinsured, plan type)

— Identify qualifying life event triggering Special Enrollment Period (SEP): marriage, birth/adoption, loss of other coverage, moving, income change for Medicaid

— Screen for dual eligibility (Medicare + Medicaid) in low-income elderly

— Assess social determinants — housing, food, transportation — via standardized tools (PRAPARE, AHC-HRSN)

— Medicare: Initial Enrollment Period = 7 months around 65th birthday (3 before, month of, 3 after). General Enrollment Jan 1–Mar 31. Medicare Advantage/Part D open enrollment Oct 15–Dec 7

— ACA Marketplace: Nov 1–Jan 15 (federal); SEPs for life events (60 days)

— Medicaid/CHIP: year-round enrollment — no closed window

— Part B: 10% premium increase per 12-month delay, lifelong

— Part D: 1% of national base premium per month delayed, lifelong

— Counsel patients turning 65 to enroll on time even if still employed (creditable coverage protects)

— Confirm USPSTF grade A/B status → ACA mandates $0 cost-sharing

— Examples: colon cancer screening 45–75, lung CT for eligible smokers, statin primary prevention discussion, HIV PrEP

Initial "workup" of an insurance problem in a vignette:

Open enrollment windows:

Late enrollment penalties:

Verifying preventive service coverage:

Board pearl: A 64-year-old still working with employer coverage from a large employer (≥20 employees) can delay Part B without penalty — they have creditable coverage. But Part B is required for those on small-employer or retiree plans, COBRA, or marketplace coverage at 65

Identify prior authorization requirements early — diagnostics like MRI, PET, specialty drugs commonly need PA

Confirmatory Studies — Cost-Sharing Mechanics and Out-of-Pocket Risk

— Premium — monthly fee to maintain coverage

— Deductible — annual amount paid before plan pays

— Copay — fixed dollar per service

— Coinsurance — percentage of allowed charge after deductible

— Out-of-pocket max — annual ceiling on patient spending (does NOT include premiums); ACA-required for marketplace and most commercial

— Minimum deductible thresholds set annually by IRS

— HSA contributions are triple tax-advantaged (deductible, growth, withdrawal for qualified medical)

— Patient must NOT have other non-HDHP coverage or Medicare to contribute

— Patients can't be balance-billed for emergency care, air ambulance, or out-of-network care at in-network facilities without consent

— Good-faith estimates required for self-pay patients

— Tier 1 generic → Tier 5 specialty; step therapy may require failing cheaper option first

— Appeal mechanisms: formulary exception, tiering exception

Cost-sharing definitions (tested directly):

Original Medicare has NO out-of-pocket maximum — patients buy Medigap (Medicare Supplement) to cap exposure; Medigap pairs only with Original Medicare, not Advantage

HDHP + HSA:

Surprise billing protections (No Surprises Act, 2022):

Drug tier structure (Part D and commercial):

Key distinction: Medicare Advantage has an OOP max (CMS sets a ceiling) and bundles Part D, but uses restricted networks — out-of-network care may be denied. Original Medicare + Medigap + Part D allows any Medicare-accepting provider nationwide but costs more in premiums

Confirm formulary status before prescribing branded agents; offer generic or therapeutic substitution when feasible — first-line answer for cost nonadherence

Risk Stratification — Matching Patient to Plan

— Age ≥65 or qualifying disability → Medicare (with Medigap or Advantage choice)

— Income ≤138% FPL in expansion state → Medicaid

— Pregnant → Medicaid covers pregnancy through 60 days postpartum (extended to 12 months in most states)

— Child in low/moderate-income family → Medicaid or CHIP (up to ~200–300% FPL state-dependent)

— No employer coverage, income 100–400% FPL → ACA Marketplace with subsidies

— Employed at large employer → typically employer-sponsored is cheapest

— Lost job → COBRA (18 months, full premium) vs Marketplace SEP (often cheaper with subsidies) vs Medicaid if income qualifies

— High-risk: fixed-income elderly on Original Medicare without Medigap or LIS; uninsured working-poor in non-expansion state; high-deductible plans with chronic disease

— Low-Income Subsidy (LIS/"Extra Help") for Part D — automatic for dual-eligibles, application-based for others up to 150% FPL

— Advantage: lower premiums, extra benefits, network limits, prior auth heavy

— Original+Medigap+D: higher premium, predictable cost, nationwide access — better for frequent travelers, complex chronic disease, snowbirds

Decision framework for selecting/advising on coverage:

Risk-stratifying for nonadherence:

Choosing between Medicare Advantage vs Original+Medigap:

Step 3 management: A newly diagnosed cancer patient on Medicare Advantage facing prior-auth delays for chemotherapy — appropriate action is initiate expedited prior authorization (72-hour standard, 24-hour expedited) and engage case management, not switch plans mid-treatment (locked until next enrollment window)

Always verify network status of oncologist, hospital, and infusion center before initiating long-course therapy

Pharmacotherapy Coverage — Part D, Formularies, and Affordability Tools

— Voluntary outpatient drug benefit via private plans

— Each plan has its own formulary; must cover at least 2 drugs per therapeutic class and all or substantially all drugs in 6 protected classes: antineoplastics, antiretrovirals, antidepressants, antipsychotics, anticonvulsants, immunosuppressants for transplant

— Standard 2025 design: deductible → initial coverage → $2,000 OOP cap (post-IRA) → catastrophic ($0 cost-share)

— Insulin capped at $35/month copay

— Vaccines on ACIP schedule (e.g., shingles, RSV) now $0 cost-share under Part D

— Part B: clinician-administered (chemo infusions, immune globulin, nebulizer solutions in DME, vaccines for flu/pneumococcal/COVID/hep B in at-risk)

— Part D: self-administered oral and most injectable outpatient drugs

— Insulin via pump (DME) = Part B; insulin via pen/syringe = Part D

— Switch to generic or therapeutic alternative

— 90-day mail-order supply

— Patient assistance programs (manufacturer, NeedyMeds, RxAssist)

— 340B pricing at qualifying clinics/FQHCs

— Low-Income Subsidy application for Medicare patients

— Pharmacy discount cards (GoodRx) for uninsured/underinsured

— All states cover outpatient Rx via Medicaid Drug Rebate Program; minimal copays

— Preferred Drug Lists vary by state

Medicare Part D essentials:

Part B vs Part D drugs (commonly tested):

Cost-reduction strategies (correct answers in cost-nonadherence stems):

Medicaid drug coverage:

Board pearl: A Medicare patient cannot use a manufacturer copay coupon for a Part D drug (anti-kickback statute) — but can use the manufacturer's patient assistance foundation if income-qualified. Commercial-insurance patients can use coupons freely

Procedures, Referrals, and Network Navigation

— HMO/Medicare Advantage HMO: PCP referral typically required for specialists; out-of-network not covered except emergencies

— PPO: no referral; out-of-network allowed at higher cost-share

— Original Medicare: no referrals needed; any participating provider

— Medicaid managed care: state-specific, usually referral-based

— Required for advanced imaging, specialty drugs, elective procedures, inpatient admissions in many MA plans

— Standard decision: 14 days (Medicare), expedited: 72 hours; urgent inpatient: 24–72 hours

— Peer-to-peer review option after denial; formal appeal rights with multiple levels (plan → independent review → ALJ → Medicare Appeals Council → federal court)

— SNF: Medicare A covers if 3 midnight inpatient stay precedes (observation status excluded); 100-day max per spell of illness

— Home health: Medicare covers if homebound and needs intermittent skilled care, ordered after face-to-face encounter

— Hospice: Medicare A covers when terminal prognosis ≤6 months certified by 2 physicians; patient forgoes curative treatment for that diagnosis

— Long-term custodial care: NOT covered by Medicare; Medicaid covers after spend-down or via waiver programs

— Inpatient vs Observation — observation is outpatient (Part B), no SNF eligibility, higher patient drug costs

— Two-midnight rule: expected stay ≥2 midnights supports inpatient

Network and referral mechanics:

Prior authorization (PA) workflow:

Post-acute care transitions:

Inpatient classification:

CCS pearl: When discharging an elderly patient to SNF, order "case management consult" and verify inpatient status was documented for ≥3 midnights — failing this triggers a denied SNF claim and patient liability. On Step 3 CCS, ordering social work / case management early is rewarded for any complex discharge

Special Populations — Elderly, ESRD, and Disability Pathways

— 24 months of SSDI entitlement → automatic Medicare

— ALS → Medicare begins the month SSDI benefits start (no waiting period)

— ESRD → Medicare eligible after 3-month waiting period if on dialysis; immediate if home dialysis training begins or kidney transplant occurs; coverage continues 36 months post-transplant (extended indefinitely for immunosuppressants in 2023+)

— Medicare primary for acute care; Medicaid covers premiums, cost-sharing, LTC, dental, transportation

— Automatically qualify for Part D Low-Income Subsidy (zero/low copays)

— D-SNPs (Dual Special Needs Plans) integrate both

— Dialysis itself bundled under Medicare ESRD benefit; covers in-center and home modalities

— Transplant immunosuppressants now lifetime-covered by Part B for Medicare-eligible transplant recipients

— Observation status post-fall → no SNF coverage → families left paying $300+/day

— Medigap underwriting: guaranteed-issue only during 6-month Medigap Open Enrollment after Part B start; later enrollment allows medical underwriting and denial

— Annual Wellness Visit (AWV) is preventive (free) — distinct from a problem-based visit

Medicare eligibility beyond age 65:

Dual-eligible beneficiaries (~12 million Americans):

Renal/hepatic considerations interface with coverage:

Elderly-specific pitfalls:

Step 3 management: A 67-year-old on dialysis asking about transplant cost — Medicare covers the transplant surgery (Part A) and immunosuppressants (Part B) for life if Medicare-eligible at transplant time. This 2023 expansion is a high-yield update

Counsel elderly to review Part D plan annually during open enrollment as formularies change

Special Populations — Pregnancy, Pediatrics, Immigrants

— Medicaid covers ~42% of US births; eligibility extended to higher income for pregnant patients (often 138–200% FPL)

— Federal mandate: postpartum Medicaid coverage 60 days minimum; most states have adopted 12-month postpartum extension (ACA option)

— ACA marketplace plans must cover maternity as Essential Health Benefit

— Pregnancy is a qualifying life event triggering SEP for marketplace enrollment

— Covers children in families with incomes too high for Medicaid but unaffordable for private (typically up to 200–300% FPL)

— Minimal cost-sharing; comprehensive including dental/vision

— Children can be enrolled in CHIP even if parents are uninsured

— Medicaid mandate for enrollees <21: comprehensive preventive, dental, vision, hearing, developmental, and any medically necessary treatment — broader than adult Medicaid

— ACA allows dependents to stay on parent's plan until age 26, regardless of marital, student, or financial status

— Lawfully present immigrants can buy Marketplace plans with subsidies; many states extend Medicaid after 5-year bar (some waive for children/pregnant)

— Undocumented immigrants: ineligible for Medicare, Medicaid (except Emergency Medicaid for emergencies including labor/delivery), and Marketplace

— FQHCs and free clinics serve regardless of status

Pregnancy coverage:

CHIP (Children's Health Insurance Program):

EPSDT (Early Periodic Screening, Diagnostic, and Treatment):

Young adults:

Immigrants:

Board pearl: An undocumented woman presenting in active labor — EMTALA mandates stabilization and Emergency Medicaid covers labor/delivery. Newborn is a US citizen and automatically eligible for Medicaid if income-qualified — enroll before discharge

Pediatric preventive care under Bright Futures schedule is $0 cost-share on all ACA-compliant plans

Complications — Coverage Gaps, Denials, and Financial Toxicity

— Cost-related nonadherence: ~25% of US adults skip/split/delay meds due to cost

— Associated with worse glycemic control, BP control, cancer outcomes, and higher mortality

— Screen with single question: "In the past 12 months, was there a time when you needed medical care but did not get it because you could not afford it?"

— Medicaid coverage cliff: small income increase disqualifies patient (especially in non-expansion states)

— ESI loss with job loss: COBRA premiums often unaffordable; SEP into marketplace usually better

— Medicare donut hole (historical) → now $2,000 OOP cap under IRA

— Observation status trap → no SNF coverage

— Out-of-network specialist or anesthesiologist → balance bill (now limited by No Surprises Act for emergencies and in-network facilities)

— Common causes: lack of prior auth, non-covered service, out-of-network, medical necessity

— Appeal steps: internal review → external/independent review → administrative law judge (Medicare) → federal court

— Hospital financial counselors and patient advocates help navigate

— Medical debt historically contributed to ~60% of personal bankruptcies; credit bureaus now exclude paid medical collections and debts <$500

— Uninsured rates highest among Hispanic, Black, low-income, and non-expansion-state populations

— Linked to delayed cancer diagnosis, worse maternal outcomes, lower vaccination

Financial toxicity as a measurable clinical complication:

Specific gap scenarios:

Claim denials and appeals:

Bankruptcy and medical debt:

Health disparities amplified by coverage:

Step 3 management: When a patient cannot afford a prescribed drug, the best next step is rarely "continue as prescribed and counsel." Correct answers: switch to generic, prescribe 90-day mail order, refer to social worker/financial counselor, enroll in patient assistance program, or apply for LIS/Medicaid

When to Escalate — Care Coordination, Social Work, and Case Management

— Uninsured or underinsured patient with new serious diagnosis

— Homelessness, food insecurity, IPV

— Suspected elder abuse/neglect (with mandatory reporting)

— Substance use needing rehab placement

— Need for advance care planning / POLST completion

— Complex discharge planning (SNF, home health, hospice, DME)

— Frequent readmissions (>2 in 6 months)

— Multiple specialists, polypharmacy

— Transition from pediatric to adult care

— Medicare Advantage prior auth navigation

— Newly diagnosed cancer, ESRD, transplant candidate

— Loss of insurance (job loss, divorce, aging out)

— Pending Medicare enrollment or Marketplace SEP

— Medication cost barriers

— 340B drug pricing at qualifying hospitals/FQHCs

— Charity care policies — nonprofit hospitals required to offer financial assistance

— Hospital Presumptive Eligibility — temporary Medicaid for emergent inpatient care

— FQHCs — sliding-scale fees, accept all comers

— Free clinics — volunteer-based, often Rx assistance

— Area Agencies on Aging — Medicare/Medicaid counseling (SHIP programs)

— 211 — community resource hotline

Triggers for social work consult:

Triggers for case management / care coordination:

Triggers for financial counselor / benefits navigator:

Hospital-based programs:

Outpatient resources:

CCS pearl: In Step 3 CCS cases involving complex discharge, order "social work consult" and "case management consult" on the order sheet early. These orders are commonly required for full credit on transition-of-care scenarios. Also order "medication reconciliation" before discharge — a Joint Commission safety standard

Key Differentials — Distinguishing Among Insurance Models

— Medicare: age/disability-based, federal, uniform nationwide, covers acute and SNF (limited), does NOT cover long-term custodial care, most dental/vision/hearing, or routine foot care

— Medicaid: income-based, federal-state, varies by state, covers LTC and EPSDT for kids; many states cover dental/vision

— Original Medicare: any participating provider, no OOP max, pair with Medigap+D

— Advantage (Part C): private plan, network restrictions, OOP max included, often $0 premium but prior auth heavy, may include dental/vision/gym

— Marketplace: individual purchase, premium tax credits 100–400% FPL, must cover 10 EHBs, guaranteed issue regardless of pre-existing conditions

— Employer: pre-tax premium, often broader networks, no individual underwriting; large-employer plans also pre-existing protected (ACA)

— COBRA: continue same plan, 18 months, full premium + 2% (often $700–2,000/month) — usually expensive

— Marketplace SEP: 60-day window, often cheaper with subsidies — typically better choice

— Medigap supplements Original Medicare cost-sharing; standardized plans A–N; guaranteed issue only in initial 6-month Medigap OEP

— Advantage replaces Original Medicare with managed care

Medicare vs Medicaid (most-tested distinction):

Medicare vs Medicare Advantage:

ACA Marketplace vs Employer-sponsored commercial:

COBRA vs Marketplace post-job-loss:

Medigap vs Medicare Advantage (cannot have both):

Key distinction: When asked "who pays for nursing home?" — Medicare pays only skilled, short-term post-acute SNF (≤100 days after 3-day inpatient). Long-term custodial nursing home care is paid by Medicaid (after spend-down) or private LTC insurance or out-of-pocket. This is among the most tested systems-based concepts

Key Differentials — Other Coverage Categories

— Active-duty military, retirees, dependents; Department of Defense

— Multiple plan options (Prime, Select); generally low cost-sharing

— Veterans enrolled based on service-connected disability, income, era of service

— Receives care at VA facilities; not technically "insurance" — integrated delivery system

— Veterans can have VA + Medicare simultaneously (common)

— Federal trust responsibility for American Indians/Alaska Natives; care at IHS facilities or contracted

— Commercial-style coverage for federal employees and retirees

— Covers occupational injury/illness; employer-funded; primary over health insurance for work-related conditions; bill workers' comp, not health insurance, for on-the-job injuries

— Motor vehicle injury care often billed to auto policy first; coordination of benefits rules apply

— Hospital must offer good-faith estimate (No Surprises Act)

— Charity care policies, sliding-scale at FQHCs

— When patient has multiple coverages, determine primary/secondary

— Working-aged Medicare + employer plan (employer ≥20 employees): employer primary, Medicare secondary

— Medicare + employer plan (<20 employees): Medicare primary

— Medicare + Medicaid (dual eligible): Medicare primary, Medicaid wraps

— ESRD with employer plan: employer primary for first 30 months, then Medicare primary

TRICARE:

VA Health Care:

IHS (Indian Health Service):

FEHB (Federal Employees Health Benefits):

Workers' compensation:

Auto/no-fault insurance:

Self-pay/uninsured:

Coordination of Benefits hierarchy (high-yield):

Board pearl: A veteran presenting with hypertension at a community ED can be treated and bill Medicare (or commercial) — VA does NOT have to be used. But for service-connected conditions, VA coverage is typically optimal. Always ask veterans about service-connected status when planning long-term care

Secondary Prevention — Maximizing Covered Preventive Services

— Cancer screening: cervical, breast (40–74), colorectal (45–75), lung CT (eligible smokers 50–80), prostate shared decision-making

— Cardiovascular: BP, lipid screening, statin counseling, AAA one-time for 65–75 male smokers

— Metabolic: diabetes screening 35–70 overweight/obese, obesity counseling, tobacco cessation

— Infectious: HIV, HCV, HBV, syphilis, gonorrhea/chlamydia (per risk), TB at-risk, PrEP for HIV

— Immunizations: full ACIP schedule including shingles, RSV, HPV through 26 (shared decision 27–45), COVID, flu, pneumococcal

— Women's: contraception (all FDA-approved methods, $0), breastfeeding support, prenatal screening, BRCA counseling at-risk

— Children: Bright Futures schedule, autism/developmental screening, fluoride varnish

— Annual Wellness Visit (not a physical exam — focused on prevention plan)

— "Welcome to Medicare" visit within first 12 months

— Cardiovascular screening, diabetes screening, bone density, mammogram, Pap, colonoscopy, lung CT, abdominal aortic aneurysm

— Vaccines: flu, pneumococcal, hepatitis B (intermediate/high risk), COVID-19, shingles and RSV now $0 via Part D under IRA

ACA-mandated $0 preventive services (USPSTF Grade A/B, ACIP vaccines, HRSA women's/children's):

Medicare-specific preventive (Part B, $0 with deductible waived):

Smoking cessation: 8 counseling sessions/year covered by Medicare and ACA plans, plus pharmacotherapy

Step 3 management: When a Medicare patient presents for "annual physical," recognize this is billed as an Annual Wellness Visit (AWV) with HRA, cognitive screening, and prevention plan — NOT a traditional head-to-toe exam. Any problem-based care during the visit incurs separate cost-sharing — document and bill appropriately

Counsel patients to use covered preventive care fully — leaving benefits unused is a missed opportunity for both health and value

Follow-Up, Monitoring, and Health Literacy Counseling

— Newly enrolled in Medicare: schedule "Welcome to Medicare" visit within first 12 months; AWV annually thereafter

— Plan change/new patient: review formulary alignment with current Rx within 30 days; medication reconciliation

— Post-hospital discharge: PCP follow-up within 7–14 days (reduces readmission; part of CMS Hospital Readmission Reduction Program)

— Open enrollment season (Oct–Dec for Medicare, Nov–Jan for Marketplace): proactively counsel patients to review plans

— Generic substitution acceptable for most chronic disease therapies; counsel patients on equivalence

— 90-day fills reduce trips, copays, and missed doses

— Medication therapy management (MTM) programs free under Part D for patients with multiple chronic conditions/drugs

— Advance directives — encourage POLST, healthcare proxy regardless of insurance

— HEDIS measures track preventive care, chronic disease control across plans

— Star Ratings for Medicare Advantage and Part D plans guide enrollment choices

— Value-based care (ACOs, MIPS, bundled payments) ties physician reimbursement to quality and cost outcomes

— Medicare.gov Plan Finder — compare Part D and Advantage plans

— Healthcare.gov — Marketplace enrollment

— SHIP (State Health Insurance Assistance Program) — free Medicare counseling

— 211 — community resources

Recommended follow-up cadence around coverage events:

Counseling priorities:

Monitoring quality and value:

Patient-facing tools:

Board pearl: A patient on 5+ chronic medications with 3+ chronic conditions under Medicare Part D qualifies for free Medication Therapy Management — a pharmacist-led annual comprehensive medication review. Referral is a high-value, low-effort intervention frequently rewarded on Step 3 SBP questions

Document health literacy level; use teach-back; provide written materials at 5th–6th grade reading level

Ethical, Legal, and Patient Safety Considerations

— Mandates medical screening exam and stabilization for any patient presenting to ED, regardless of insurance, citizenship, or ability to pay

— Applies before any inquiry about payment

— Violations carry hospital fines and physician penalties

— Cannot delay screening or treatment to verify coverage

— Prohibit financial inducement for referrals involving federal payers

— Why Medicare patients cannot use manufacturer drug coupons for Part D drugs

— ACA Section 1557 prohibits discrimination by race, color, national origin, sex (including pregnancy, sexual orientation, gender identity), age, disability in any health program receiving federal funds

— Cannot refuse care or alter treatment based on insurance status in ways that violate professional ethics

— Patients have right to be informed of expected out-of-pocket costs when feasible (No Surprises Act good-faith estimates)

— For elective procedures, discuss in-network status and pre-authorization status

— Medication reconciliation errors at hospital discharge — leading cause of preventable readmission

— Observation status surprise: families unaware patient was not "admitted" face unexpected SNF bills — communicate status clearly

— Newborns must be added to parent's coverage within 30 days

EMTALA (Emergency Medical Treatment and Labor Act):

Anti-Kickback Statute and Stark Law:

HIPAA: protects PHI across all payers; insurance status itself is PHI

Nondiscrimination:

Informed consent and financial implications:

Transition-of-care risks (Step 3 hot zone):

Conflict of interest: physicians must not let plan economics (capitation, RVU pressure, gainsharing) drive medical decisions away from patient benefit

Mandatory reporting intersections: insurance fraud, suspected elder financial exploitation (often linked to medical-debt scams)

Step 3 management: An undocumented patient arrives in active labor — proceed with full obstetric care under EMTALA; bill Emergency Medicaid; enroll the US-citizen newborn in Medicaid before discharge. Do NOT contact immigration authorities — outside scope, violates trust, and may breach state sanctuary protections

Star Ratings guide Medicare plan choice

Insulin via DME pump = Part B; pen = Part D

Transplant immunosuppressants: lifetime Part B coverage post-2023

Board pearl: When a stem mentions "the patient cannot afford…" the answer is almost never to simply educate or escalate medication — it is to switch to generic, refer to social work/case management, or connect to a financial/benefit program. This pattern recurs across Step 3 SBP questions

Board Question Stem Patterns

— Diabetic with rising A1c admits to skipping insulin doses because of cost

— Wrong: increase dose / counsel on adherence

— Right: switch to less expensive insulin (NPH/regular), prescribe 90-day supply, refer to social worker, apply for LIS/manufacturer assistance, verify Medicare insulin $35 cap

— 64-year-old still working at large company asks about Medicare

— Right: can delay Part B without penalty (creditable employer coverage); must enroll within 8 months of losing employer coverage to avoid lifetime penalty

— Elderly patient admitted under "observation" for 4 days, needs rehab

— Right: SNF not covered by Medicare (no qualifying 3-day inpatient stay); options include home health, paying privately, or Medicaid if eligible

— Pregnant undocumented patient in labor

— Right: EMTALA stabilization + Emergency Medicaid for delivery + enroll citizen newborn in Medicaid

— Laid-off patient with chronic illness, asks about coverage

— Right: compare COBRA (continuity, expensive) vs Marketplace SEP with subsidies (often cheaper); Medicaid if income qualifies

— Low-income elderly needing nursing home placement long-term

— Right: Medicaid covers long-term custodial care (after spend-down); Medicare only covers short-term skilled SNF

— Patient declines colonoscopy citing cost

— Right: USPSTF Grade A/B screening colonoscopy is $0 cost-share under ACA and Medicare; reassure and schedule

— Specialty drug denied by MA plan

— Right: initiate expedited prior auth / peer-to-peer / formulary exception, engage case management

— Medicare patient comes for "physical"

— Right: bill as AWV; document HRA, cognitive screen, prevention plan; separate problem-based care if needed

Pattern 1 — The cost nonadherence stem:

Pattern 2 — The turning-65 stem:

Pattern 3 — The SNF discharge stem:

Pattern 4 — The undocumented obstetric stem:

Pattern 5 — The job-loss stem:

Pattern 6 — The dual-eligible LTC stem:

Pattern 7 — The preventive-service cost stem:

Pattern 8 — The prior-auth delay stem:

Pattern 9 — The Annual Wellness Visit stem:

Step 3 management: When stem offers "verify insurance coverage before treating" in an emergency — always wrong. EMTALA mandates care first

One-Line Recap

Rapid recap bullets:

US health coverage is a stratified system — Medicare (age/disability, federal), Medicaid (income, federal-state, covers LTC), ACA Marketplace (subsidized individual), and commercial (employer-sponsored) — and Step 3 expects you to match the patient to the right plan, leverage $0 preventive benefits and assistance programs, navigate prior auth and network rules, and never let coverage delay emergency care.

Medicare = 65+/disability/ESRD/ALS; Parts A (hospital), B (outpatient, $0 preventive), C (Advantage), D (Rx with $2,000 cap and $35 insulin); Original Medicare has no OOP max — needs Medigap

Medicaid = income-based, covers long-term custodial care (Medicare does not), EPSDT for kids, pregnancy through 60 days (often 12 months); year-round enrollment; expansion states cover up to 138% FPL

ACA Marketplace = subsidized individual plans, 10 Essential Health Benefits, USPSTF A/B services at $0 cost-share, dependent coverage to age 26, SEPs after life events (60 days), open enrollment Nov 1–Jan 15

Commercial = employer-sponsored dominates under-65 working population; HMO/PPO/HDHP; COBRA continues coverage 18 months post-job-loss but Marketplace SEP often cheaper

EMTALA mandates stabilization regardless of coverage; undocumented patients access only Emergency Medicaid and FQHCs

When cost is a barrier — switch to generics, 90-day fills, patient assistance programs, social work referral, LIS for Medicare — never just "counsel adherence"

CCS pearl: Order social work, case management, and medication reconciliation early for any complex discharge — these orders are the systems-based backbone of Step 3 management
