Care Manager Roles and Responsibilities

Care managers occupy a structured clinical and administrative role within healthcare delivery systems, coordinating services across providers, payers, and community resources on behalf of patients with complex, chronic, or transitional health needs. This page defines the functional scope of care manager responsibilities, the regulatory and credentialing frameworks that govern the role, and the operational boundaries that separate care management from adjacent functions such as case management, utilization review, and direct clinical care. Understanding the role is foundational to evaluating how care management models and frameworks are implemented across different care settings.

Definition and scope

A care manager is a health professional — most commonly a registered nurse (RN), licensed clinical social worker (LCSW), or licensed professional counselor (LPC) — who provides systematic oversight of a patient's health services across the care continuum. The role is formally defined within the Case Management Society of America (CMSA) Standards of Practice for Case Management (2022 revision), which describes the care manager's function as facilitating "the achievement of patient goals and optimal health outcomes" through assessment, planning, facilitation, care coordination, evaluation, and advocacy.

The Commission for Case Manager Certification (CCMC) further delineates scope through its CCM Certification Guide, categorizing core care manager competencies across six knowledge domains: care delivery and reimbursement methods, psychosocial concepts, quality and outcomes evaluation, rehabilitation concepts, ethical and legal issues, and care management concepts.

At the regulatory level, the Centers for Medicare & Medicaid Services (CMS) references care manager functions in the context of Chronic Care Management (CCM) and Transitional Care Management (TCM) billing codes under the Medicare Physician Fee Schedule (CMS, 42 CFR Part 414). These codes require that designated non-physician personnel meet documented competency thresholds, effectively setting a federal floor for care manager qualification in Medicare-participating practices.

How it works

The care management process follows a structured workflow grounded in the nursing process and population health frameworks. The CMSA Standards of Practice (2022) define eight discrete phases:

  1. Identification and selection — Patients are flagged through risk stratification in care management tools, referral, or payer criteria.
  2. Assessment — The care manager conducts a comprehensive biopsychosocial evaluation covering medical history, functional status, social determinants, and health literacy.
  3. Problem identification — Clinical and non-clinical barriers to care are catalogued and prioritized.
  4. Planning — A patient-centered care plan is developed collaboratively with the patient, family, and interdisciplinary care team.
  5. Implementation — Services, referrals, authorizations, and community resources are activated.
  6. Coordination — The care manager serves as the primary communication hub between providers, payers, and post-acute services.
  7. Evaluation — Outcomes against care plan goals are measured at defined intervals using care management quality metrics.
  8. Transition or disengagement — The patient is stepped down to self-management, transferred to another program, or discharged from active management.

The care manager role is distinct from the attending physician role in that care managers do not diagnose or prescribe; their authority is coordinative and facilitative. Within utilization management in healthcare, care managers may gather clinical information for authorization reviews but do not make the final coverage determination — that function belongs to the utilization management reviewer or medical director.

Common scenarios

Care manager responsibilities vary substantially by setting and population. Four primary deployment contexts define the majority of practice patterns:

Ambulatory chronic disease management: In outpatient settings, care managers monitor patients with conditions such as diabetes, heart failure, or COPD. Functions include medication reconciliation, appointment adherence tracking, patient education, and early identification of decompensation signals. Chronic disease care management programs funded under CMS CCM billing (CPT code 99490 and related codes) require at least 20 minutes per calendar month of clinical staff time directed by a physician or qualified health professional.

Hospital-based transitional care: Care managers embedded in acute-care settings execute discharge planning and post-acute care protocols. Under CMS Conditions of Participation at 42 CFR § 482.43, hospitals are required to have a discharge planning process, and care managers are the primary practitioners who operationalize this requirement.

Health plan care management: Managed care organizations employ care managers to reduce avoidable utilization, coordinate specialty referrals, and manage high-cost members. The National Committee for Quality Assurance (NCQA) Health Plan Accreditation Standards specify competency and documentation requirements for care managers functioning within plan-based programs.

Behavioral health integration: In integrated models, care managers — often social workers with LCSW credentials — coordinate mental health and substance use services alongside medical care. Behavioral health care management programs operating under the CMS Collaborative Care Model (CoCM) billing codes (HCPCS G0502–G0504) define specific care manager functions distinct from those of the behavioral health consultant.

Decision boundaries

Precise delineation of the care manager role is both a regulatory requirement and a patient safety consideration. The CCMC and CMSA jointly identify the following boundary conditions:

Care manager vs. case manager: The terms are frequently used interchangeably, but CCMC distinguishes them by intensity and duration. Case management typically addresses episodic, high-acuity events (e.g., catastrophic injury, acute hospitalization) with a defined closure point. Care management generally implies longer-term, longitudinal oversight of chronic conditions. Case management certification requirements govern credentialing for both functions.

Care manager vs. care coordinator: Per NCQA and the Agency for Healthcare Research and Quality (AHRQ) Care Coordination Measures Atlas, care coordination is a task-level activity (scheduling, information transfer), while care management involves clinical judgment, goal-setting, and outcome accountability. The distinction is detailed in care coordination vs. care management.

Scope of clinical authority: Care managers operating under nurse practice acts (governed state-by-state by boards of nursing under the National Council of State Boards of Nursing framework) may not exceed the authorized scope of their license. When a care manager identifies an acute clinical change, the required action is escalation to a licensed prescriber — not independent clinical intervention.

Documentation requirements: CMS requires that care manager activities under CCM and TCM codes be documented in a certified electronic health record with sufficient specificity to support billing. The HIPAA and care management privacy framework additionally requires that care plan documentation and inter-provider communications meet the minimum necessary standard under 45 CFR § 164.502(b).
