Reimbursement and utilization management are core CCM knowledge areas. Case managers must understand how healthcare is financed to advocate for appropriate services and manage resources effectively.
Healthcare Financing Overview
Public programs (Medicare ~18%, Medicaid ~16%), private insurance (~34%), self-pay/uninsured — CM must navigate all payer types and understand how each reimburses for care.
Utilization Management
Process of evaluating necessity, appropriateness, and efficiency of healthcare services; ensures right care, right setting, right time — a core function of the case manager role.
Value-Based Care
Shifts payment from volume (fee-for-service) to value (outcomes + quality); ACOs, bundled payments, and Pay for Performance (P4P) programs realign provider incentives.
Case Manager's UM Role
CM performs or supports prospective (prior auth), concurrent (continued stay), and retrospective (post-service) reviews — ensuring appropriate utilization across all settings.
| Part | Coverage | Key Points |
|---|---|---|
| Part A | Hospital inpatient, SNF, hospice, home health | Premium-free for most; deductible per benefit period |
| Part B | Outpatient, physician, preventive, DME | Monthly premium; 80/20 coinsurance after deductible |
| Part C | Medicare Advantage (private plans) | Combines A+B, often includes Part D; capitated payment model |
| Part D | Prescription drugs | Formulary-based; coverage gap ("donut hole") applies |
| Days | Coverage | CM Action |
|---|---|---|
| Days 1–20 | Fully covered — no patient copayment | Ensure qualifying 3-day inpatient hospital stay |
| Days 21–100 | Copay ~$200/day (amount updated annually) | Assess supplemental/Medigap coverage; financial counseling |
| Day 101+ | No Medicare coverage | Explore Medicaid, supplemental insurance, or self-pay options |
Homebound Status
Patient must be homebound — leaving home requires considerable effort; taxing physically or mentally.
Skilled Care Needed
Requires skilled nursing, physical therapy (PT), or speech-language pathology (SLP) services.
Physician Order
Care must be ordered by a physician or allowed practitioner; plan of care must be established and reviewed.
Medicare-Certified Agency
Services must be provided by a Medicare-certified home health agency.
Intermittent Care Only
Care must be intermittent (not 24-hour continuous) — typically <8 hrs/day, <28 hrs/week.
| Feature | Detail |
|---|---|
| Administration | Joint federal-state; states set eligibility within federal minimums |
| Eligibility | Low income; mandatory groups include children, pregnant women, and disabled individuals |
| LTSS | Long-Term Services & Supports; waiver programs available for home/community-based care (HCBS) |
| Dual Eligibles | Individuals enrolled in both Medicare + Medicaid; "Duals" — coordination of benefits is critical |
| FMAP | Federal Medical Assistance Percentage — federal match rate to states; varies by state income |
| Plan Type | Network | Referral Needed | Key Feature |
|---|---|---|---|
| HMO | Closed, in-network only | Yes (PCP gatekeeper) | Lowest cost, least flexibility |
| PPO | Open (in + out of network) | No | More flexibility, higher cost |
| POS | Hybrid HMO/PPO | Yes for in-network | Mid-level flexibility/cost |
| HDHP | Varies | Varies | High deductible; pairs with HSA |
| EPO | In-network only | No PCP required | Moderate cost, no out-of-network coverage |
Fee-for-Service (FFS)
Payment per service rendered; volume-based; incentivizes overuse; traditional Medicare/Medicaid default model.
Capitation
Fixed per-member-per-month (PMPM) payment regardless of services used; incentivizes prevention; risk shifted to provider.
DRG (Diagnosis-Related Group)
Medicare pays fixed amount based on diagnosis category; incentivizes efficiency and shorter LOS; case managers manage avoidable days.
Per Diem
Fixed daily rate; common in SNF, inpatient psych settings; CM actively manages length of stay to control costs.
Bundled Payment
Single payment for an episode of care (e.g., hip replacement + 90-day recovery); shared across providers; incentivizes coordination.
Pay for Performance (P4P)
Bonuses or penalties tied to quality metrics (HEDIS, readmission rates, patient satisfaction scores) rather than volume.
ACO (Accountable Care Organization)
Groups of providers who jointly take responsibility for cost and quality for a defined population; share savings with CMS when benchmarks are met.
Patient-Centered Medical Home (PCMH)
Primary care model with comprehensive, coordinated, accessible care; CM is often embedded in primary care practice to support complex patients.
Prospective Review (Prior Authorization)
Review BEFORE service is provided; determines medical necessity; prevents unnecessary care. Delays in prior auth can create access barriers for patients.
Concurrent Review
Review DURING hospitalization or ongoing care; assesses continued medical necessity; drives LOS management. CM communicates daily with the clinical team.
Retrospective Review
Review AFTER service has been provided; determines if care was appropriate and medically necessary; can result in payment denial. Appeals process is available.
| Term | Definition |
|---|---|
| Medical Necessity | Service is appropriate, clinically indicated, not experimental; meets payer criteria (InterQual/MCG) |
| Level of Care | Setting appropriate to clinical needs (ICU → step-down → acute → SNF → home); CM matches patient to right setting |
| InterQual / MCG | Nationally recognized UM criteria sets used by payers to evaluate medical necessity and level of care |
| Denial | Payer refuses to cover a service; may be clinical (medical necessity) or administrative in nature |
| Appeal | Formal process to contest a denial; CM prepares and submits clinical documentation supporting medical necessity |
| Peer-to-Peer Review | CM or physician speaks directly with payer's medical director to verbally justify care and attempt to overturn a denial |
| Expedited Appeal | For urgent or ongoing care denials; requires faster timeline and response from payer |
| External Review | Independent Review Organization (IRO) evaluates denial; decision is binding on the health plan |
Length of Stay (LOS) Management
CM tracks actual vs. expected LOS; works with clinical team to resolve delays (social, clinical, or system barriers); facilitates early discharge planning.
Avoidable Days
Hospital days that are medically unnecessary; may not be reimbursed by the payer; CM identifies root causes of delays and resolves them proactively.
Discharge Planning
Begins at admission; CM assesses post-acute needs (SNF, home health, rehab); arranges appropriate level of care to ensure a safe, timely discharge.
Readmission Prevention
CM ensures follow-up appointments, medication reconciliation, patient/caregiver education, and support systems are in place before discharge.

Use these mnemonics and memory hooks to lock in high-yield CCM concepts before exam day.
Medicare Parts A–D
A = Hospital/SNF • B = outpatient/physician Bills • C = Coverage via Advantage plans • D = Drug coverage
UM Review Types
Prospective = Before (prior auth) • Concurrent = During (LOS review) • Retrospective = After (payment review)
DRG Impact
DRG pays one fixed amount regardless of LOS → hospital incentivized to discharge efficiently → CM manages avoidable days
HMO vs PPO
HMO: PCP gatekeeper required, lowest cost, in-network only • PPO: no referral needed, more freedom, higher cost
Medical Necessity
Must meet payer criteria (InterQual/MCG): appropriate setting, clinically indicated, not experimental or elective
Value-Based Care
ACOs, P4P, bundled payments all shift incentives from volume (FFS) to value (quality + efficiency + outcomes)
Start with Medicare Parts A–D (mnemonic: Hospitals, Bills, Coverage, Drugs). Then learn the 3 UM review types: Prospective (before), Concurrent (during), Retrospective (after). These two areas alone appear frequently on the CCM exam.
Study managed care plan types (HMO vs PPO vs POS vs EPO vs HDHP), DRG payment logic, and how capitation shifts financial risk to the provider. Know the Medicare SNF benefit day tiers cold: Days 1–20 full, 21–100 copay, 101+ none.
Focus on value-based care models (ACO, PCMH, bundled payments, P4P), the full denial and appeals process (peer-to-peer, expedited, external IRO review), InterQual/MCG criteria sets, and strategies for managing avoidable days and LOS.
