Care Coordination and Case Management Services for Older Adults

Care coordination and case management are structured service frameworks designed to align the medical, functional, and psychosocial needs of older adults across multiple providers, settings, and systems. This page covers how these services are defined under federal and professional standards, the operational mechanisms through which they function, the clinical and social scenarios that trigger their use, and the boundaries that distinguish coordination from clinical treatment. Understanding these frameworks is essential for navigating the fragmented landscape of elder health services, where the average Medicare beneficiary sees 7 different physicians annually and manages 2 or more chronic conditions.

Definition and Scope

Care coordination, as defined by the Agency for Healthcare Research and Quality (AHRQ), is the deliberate organization of patient care activities and information sharing among all participants concerned with a patient's care to achieve safer and more effective outcomes. Case management is a related but distinct function: it refers to an individualized, ongoing process of assessing needs, planning services, linking individuals to resources, monitoring progress, and advocating on behalf of a specific client.

The Centers for Medicare & Medicaid Services (CMS) recognizes both functions within its billing and coverage frameworks. Under the Medicare Physician Fee Schedule, Chronic Care Management (CCM) codes — specifically CPT codes 99490, 99491, and 99487 — reimburse non-face-to-face care coordination for beneficiaries with 2 or more chronic conditions. Transitional Care Management (TCM) codes (99495 and 99496) apply specifically to post-discharge coordination. These billing designations mark a regulatory line between coordination as a billable clinical activity and informal caregiver navigation.

Professionally, case managers working with older adults may hold credentials from the Commission for Case Manager Certification (CCMC), which administers the Certified Case Manager (CCM) credential, or from the Case Management Society of America (CMSA), which publishes the Standards of Practice for Case Management. These frameworks establish competency expectations but do not carry the force of federal regulation.

The scope of these services spans five primary domains: medical management, functional assessment, psychosocial support, financial navigation, and care transitions. Services may be delivered by registered nurses, licensed social workers, geriatric care managers, or interdisciplinary teams depending on setting and payer.

How It Works

Care coordination and case management follow a structured process regardless of the specific credential or setting involved. The CMSA Standards of Practice identify six core phases:

1. Screening and identification — Determining which individuals meet criteria for services, often using validated tools such as the Hierarchical Condition Category (HCC) risk scores used by CMS or the Geriatric Assessment instruments endorsed by the American Geriatrics Society (AGS).
2. Comprehensive assessment — Evaluating medical history, functional status (commonly measured by Activities of Daily Living scales), cognitive capacity, social supports, caregiver burden, and financial situation.
3. Care plan development — Creating a documented, goal-oriented plan that addresses priority needs, assigns responsibility to specific providers or services, and sets measurable outcomes.
4. Implementation and linkage — Connecting the individual to appropriate services across the medical and community continuum, including home health care, chronic disease management programs, and pharmacy services.
5. Monitoring and follow-up — Ongoing outreach to assess adherence, emerging needs, and changes in condition, often conducted via telephone or telehealth.
6. Transition or closure — Formally ending case management when goals are met, the individual stabilizes, or transitions to another care setting such as hospice or palliative care.

The distinction between coordination and case management lies primarily in intensity and accountability. Coordination typically involves one-time or episodic alignment of services — communicating a specialist's findings back to a primary care physician, for example. Case management involves ongoing, individualized monitoring of a named individual over time, with a designated case manager who holds accountable responsibility for service coherence.

Common Scenarios

Case management and coordination services are activated by predictable clinical and social trigger conditions. The following scenarios represent the most common documented use patterns in elder populations:

Post-hospitalization transitions: Older adults discharged from an acute care setting face elevated 30-day readmission risk. CMS data show that approximately 20 percent of Medicare fee-for-service beneficiaries are readmitted within 30 days of discharge (CMS, Medicare Payment Advisory Commission data). Transitional care managers follow up within 48 to 72 hours of discharge, reconcile medications, and confirm outpatient follow-up appointments. This directly intersects with elder transitional care services.

Polypharmacy management: Beneficiaries taking 5 or more concurrent medications — a threshold the American Geriatrics Society associates with heightened adverse drug event risk — benefit from case management that coordinates prescribing across specialists. The Beers Criteria, published by the AGS, provides a named risk classification framework used by case managers to flag high-risk medications. More detail on this intersection appears in polypharmacy and medication management.

Dementia-related care complexity: Individuals with Alzheimer's disease or related dementias typically require coordination across neurology, psychiatry, adult day programs, in-home care, and legal planning services. The Alzheimer's Association publishes care planning guidelines that case managers frequently reference. See also dementia and Alzheimer's care services.

Social determinants of health: Case managers increasingly address non-clinical barriers such as food insecurity, housing instability, and transportation gaps, consistent with Healthy People 2030 objectives established by the U.S. Department of Health and Human Services. This overlaps with elder social determinants of health.

Decision Boundaries

Understanding what care coordination and case management do not cover is as important as understanding their scope.

Coordination is not clinical treatment. A care coordinator or case manager does not prescribe medications, order diagnostic tests, or provide direct clinical intervention. Those functions remain within the scope of licensed treating providers such as geriatric medicine specialists or elder primary care physicians.

Case management is not legal or financial guardianship. A case manager may assist with identifying legal or financial resources, but the role does not confer decision-making authority. Advance care planning — including durable powers of attorney and healthcare directives — is a distinct domain covered separately under elder advance care planning.

Payer-based coordination has regulatory limits. Medicare's CCM and TCM billing codes require specific provider qualifications, documented care plans of minimum required content, and defined minimum monthly time thresholds. CMS publishes these requirements in the Medicare Claims Processing Manual, Chapter 12. Medicaid-funded case management programs vary by state under 1915(c) waiver authority and may cover populations and services not included in Medicare.

Professional credential does not determine service eligibility. Whether an older adult qualifies for case management depends on payer criteria, clinical thresholds, and program-specific rules — not solely on the availability of a credentialed case manager. Many Area Agencies on Aging (AAAs), authorized under the Older Americans Act (OAA), provide case management services that operate outside Medicare and Medicaid billing frameworks entirely.
