Resource Management, Reimbursement, and Payer Requirements
Core concepts
Resource management balances clinical need, patient preference, cost, and payer rules. Know major payers: Medicare, Medicaid, commercial plans, Medicare Advantage, and managed Medicaid. Understand coverage versus medical necessity, prior authorization, concurrent review, denials and appeals, DRGs, capitation, bundled payments, value-based contracts, formularies, networks, and patient financial responsibility. Medicare generally does not cover custodial care. SNF coverage generally requires a qualifying inpatient hospital stay, and observation time does not count. The two-midnight rule informs inpatient admission decisions. Home health and DME have specific eligibility and documentation requirements.
Traps
Authorization is not a guarantee of payment. A payer rule may limit options, but the clinical plan should still be driven by assessed need. Do not confuse Medicare and Medicaid eligibility or assume all services are covered. Watch for questions that ignore patient cost-sharing, charity care, or appeal rights. Documentation should describe objective functional and medical necessity, not just a diagnosis or convenience.
Worked example
A patient needs SNF care but lacks a qualifying inpatient stay. The case manager should explore home-based alternatives, therapy, caregiver support, and appeal or exception options while documenting clinical need. Choosing SNF solely because it is "covered" is the wrong reasoning.
Rule of thumb
Clinical need determines the plan; payer rules determine the pathway and documentation. Never reverse those priorities.
