Care Coordination and Case Management Services for Patients

Care coordination and case management are structured clinical and administrative processes that organize a patient's care across providers, settings, and time. These functions are particularly critical for patients managing chronic illness, complex diagnoses, behavioral health conditions, or transitions between care settings such as hospital discharge to home or rehabilitation. Understanding how these services are defined, funded, and operationally delivered helps patients and their representatives navigate the healthcare system with greater clarity.

Definition and scope

Care coordination and case management are related but distinct functions within the U.S. healthcare delivery system. The Agency for Healthcare Research and Quality (AHRQ) defines care coordination as "deliberately organizing patient care activities and sharing information among all of the participants concerned with a patient's care to achieve safer and more effective care" (AHRQ Care Coordination). Case management is a narrower, more intensive intervention typically assigned to a named individual — a case manager — who actively manages a patient's plan across episodes of care.

The Centers for Medicare & Medicaid Services (CMS) distinguishes at least 3 billable coordination service categories under Medicare:

Chronic Care Management (CCM) — for patients with 2 or more chronic conditions expected to last at least 12 months (CMS CCM Fact Sheet)
Transitional Care Management (TCM) — for patients following discharge from a hospital, skilled nursing facility, or other inpatient setting
Principal Care Management (PCM) — for patients with a single high-complexity chronic condition requiring specialist-level oversight

Case management as a professional practice is governed in part by the Commission for Case Manager Certification (CCMC), which publishes a Code of Professional Conduct setting ethical standards for Certified Case Managers (CCMs). The Case Management Society of America (CMSA) publishes Standards of Practice for Case Management, most recently revised in 2022.

The scope of these services extends across payer types. Medicaid managed care plans are required under 42 C.F.R. § 438.208 to implement coordination of care for enrollees with special health care needs. For a broader understanding of how Medicaid eligibility and enrollment intersects with care coordination entitlements, that framework provides essential context.

How it works

The operational structure of care coordination and case management follows a defined sequence regardless of the setting.

Identification and screening — Patients are flagged through risk stratification tools, claims data analysis, provider referral, or self-referral. High-cost, high-utilization patients with 4 or more emergency department visits in 12 months are a common threshold for program eligibility in commercial and Medicaid managed care contracts.
Assessment — A comprehensive assessment captures clinical status, functional ability, social determinants of health, and patient goals. The CMSA Standards specify that assessments must be interdisciplinary and patient-centered.
Care plan development — A written care plan is produced, identifying goals, responsible parties, timelines, and escalation protocols. Under CMS CCM requirements, this plan must be electronically shared with all treating providers.
Implementation and monitoring — The case manager coordinates referrals, verifies that services are initiated, and monitors outcomes at defined intervals. Contact frequency varies: CCM requires a minimum of 20 minutes of clinical staff time per calendar month (CMS CCM).
Transition and closure — Cases are closed when goals are met, the patient declines services, or the patient transitions to a higher level of care such as hospice.

The prior authorization process is frequently a parallel workflow within case management, as case managers often facilitate authorization requests for specialist referrals, home health, or durable medical equipment. The specialist referral process similarly intersects with care coordination when patients require multi-specialty management.

Common scenarios

Care coordination and case management services apply across a range of clinical and social circumstances:

Post-acute discharge planning — Following a hospital admission, TCM services ensure a follow-up appointment occurs within 7 or 14 calendar days depending on complexity. Post-acute care options such as skilled nursing, home health, or inpatient rehabilitation require care plan continuity across settings.
Chronic disease management — Patients with diabetes, congestive heart failure, chronic obstructive pulmonary disease, or end-stage renal disease are primary targets of CCM programs. Chronic disease management programs frequently operate in coordination with a primary care physician who retains clinical oversight.
Behavioral health integration — Patients with co-occurring mental health and substance use disorders require coordinated care across behavioral and physical health providers. Federal parity law under the Mental Health Parity and Addiction Equity Act, enforced by the Department of Labor and HHS, prohibits insurance plans from imposing more restrictive limits on mental health services access than on comparable medical-surgical benefits.
Pediatric and maternal health — CHIP and Medicaid require care coordination for children with special health care needs under Title XXI of the Social Security Act. Children's Health Insurance (CHIP) beneficiaries with complex medical needs are commonly enrolled in health plan case management programs.
Social determinant-driven complexity — Patients facing housing instability, food insecurity, or transportation barriers are increasingly triaged into care coordination programs that address social determinants of health alongside clinical needs.

Decision boundaries

Care coordination and case management are not equivalent to primary care, social work, or patient advocacy, although their functions may overlap.

Function	Primary Purpose	Licensed Professional Required?	Billed Separately?
Care Coordination (CCM/TCM)	Organize multi-provider care plans	Clinical staff under licensed provider	Yes (CMS CPT codes)
Case Management	Intensive individual care oversight	Certified Case Manager (optional) or RN/SW	Varies by payer
Patient Advocacy	Rights navigation and grievance support	Not required	Generally no
Social Work Services	Social determinant and psychosocial assessment	Licensed Social Worker (LCSW/LSW)	Yes, separately coded

A care coordinator employed by a hospital operates under the hospital's conditions of participation governed by CMS Conditions of Participation at 42 C.F.R. § 482. A case manager working within a health insurance plan operates under state insurance regulations and CMS managed care rules at 42 C.F.R. § 438. These are structurally different accountability frameworks even when the patient-facing activities appear similar.

Patients enrolled in Medicare Advantage plans receive care coordination services defined by each plan's benefit structure, which must meet CMS minimum requirements under Medicare Parts A, B, C, D. Patients in fee-for-service Medicare may receive CCM or TCM services only if their provider has enrolled in the relevant CMS billing programs.

Eligibility for case management through a Medicaid plan, a commercial insurer, or a hospital-based program is not automatic. It depends on clinical criteria, plan-specific thresholds, and in some states, separate Medicaid waiver authority under Section 1915(c) of the Social Security Act.
