Medical and Health Services Directory: Purpose and Scope

The National Care Management Authority directory organizes reference-grade information about care management programs, clinical frameworks, regulatory standards, and workforce roles across the United States health system. This page explains the structural logic behind the directory, the criteria governing how listings and topic pages are maintained, and the boundaries of what the directory covers versus what falls outside its scope. Understanding these parameters helps readers locate the correct reference material and interpret the classification boundaries that separate one topic category from another.

How the directory is maintained

The directory is organized around publicly documented care management functions, regulatory program categories, and professional standards established by named standards bodies and federal agencies. Entries are classified according to frameworks published by the Centers for Medicare & Medicaid Services (CMS), the Case Management Society of America (CMSA), the National Committee for Quality Assurance (NCQA), and the Utilization Review Accreditation Commission (URAC). These organizations publish program definitions, accreditation standards, and billing code specifications that provide objective classification boundaries for directory content.

Topic pages are structured to reflect how CMS distinguishes billable care management service types — for example, Chronic Care Management (CCM) under CPT code 99490, Transitional Care Management (TCM) under CPT codes 99495 and 99496, and Principal Care Management (PCM) under CPT codes 99424–99427. These distinctions are not editorial choices; they map directly to Medicare program definitions published in the CMS Physician Fee Schedule. Directory entries that address reimbursement contexts are cross-referenced to the care-management-reimbursement-and-billing reference page for structural detail.

Entries covering professional roles align with competency frameworks from CMSA's Standards of Practice for Case Management (2022 edition) and credentialing requirements maintained by the Commission for Case Manager Certification (CCMC). Population-level program entries reference the CMS Innovation Center's model definitions and the Agency for Healthcare Research and Quality (AHRQ) care coordination framework.

The directory is not a static document. Topic classification is updated when federal agencies publish revised program definitions, when accreditation standards are reissued, or when new CPT or HCPCS code structures alter the regulatory landscape. Structural changes to program categories — such as the expansion of behavioral health integration codes under CMS in 2018 and subsequent years — are reflected in topic scope descriptions when the underlying agency guidance is verifiable.

What the directory does not cover

The directory does not provide clinical advice, treatment protocols, medication guidance, or patient-specific care recommendations. It covers administrative, regulatory, and organizational dimensions of care management — not bedside clinical practice.

The following categories fall outside the directory's scope:

1. Individual provider or facility listings — The directory does not list specific hospitals, physician practices, home health agencies, or individual care managers. Facility-level data is maintained by CMS at the Care Compare portal and by state health departments.
2. Insurance plan benefit comparisons — Coverage determinations, formulary details, and plan-specific network information are outside scope. The health-plan-care-management-programs page covers structural program types only, not plan-specific benefits.
3. Legal or compliance advice — Regulatory frameworks are described structurally. Interpretations of liability, malpractice standards, or legal obligations are not provided. HIPAA applicability is described at the hipaa-and-care-management-privacy reference page in structural terms only, per 45 CFR Parts 160 and 164 as published by the HHS Office for Civil Rights.
4. Real-time clinical guidelines — Clinical practice guidelines from bodies such as the American Diabetes Association or the American College of Cardiology are referenced structurally where they intersect with care management program design, but the directory does not republish or interpret clinical content.
5. Crisis intervention resources — Acute behavioral health crisis lines, emergency services, and inpatient psychiatric routing fall outside this directory's coverage.

The distinction between care coordination and care management — a boundary with direct billing and scope-of-practice implications — is addressed at care-coordination-vs-care-management.

Relationship to other network resources

The directory functions as a classification and navigation layer. Topic pages such as chronic-disease-care-management, geriatric-care-management, and population-health-management provide structured reference content organized around specific program types, regulatory contexts, or patient population categories. The directory index at medical-and-health-services-listings provides the full enumerated entry list.

Readers seeking conceptual orientation before navigating topic pages can use how-to-use-this-medical-and-health-services-resource, which explains the classification logic in plain terms. The medical-and-health-services-topic-context page situates care management within the broader US health system policy context, including the role of the Affordable Care Act's Section 3021 (establishing the CMS Innovation Center) in expanding care management program infrastructure after 2010.

Cross-references between directory entries are based on documented programmatic relationships — for example, the overlap between accountable care organization structures and care management obligations is covered at accountable-care-organizations-and-care-management, while the quality measurement frameworks that govern those relationships are addressed at care-management-quality-metrics.

How to interpret listings

Each directory entry specifies three classification dimensions: program type, regulatory context, and population scope.

• Program type distinguishes care management models by operational mechanism — episodic (transitional care management), longitudinal (chronic care management), population-stratified (risk stratification programs), or integrated (behavioral health integration). These distinctions track CMS service category definitions.
• Regulatory context identifies the governing framework — Medicare fee-for-service, Medicaid managed care (governed by 42 CFR Part 438), commercial accreditation standards (NCQA, URAC), or multi-payer value-based arrangements.
• Population scope classifies entries by the patient population the program addresses — pediatric, geriatric, maternal, oncology, rare disease, or general adult. Where a program spans population types (such as complex care management, addressed at complex-care-management), that breadth is noted explicitly.

Entries that carry accreditation relevance are cross-referenced to care-management-accreditation-bodies, which catalogs the standards-setting organizations and their specific accreditation program structures. Workforce-related entries reference the competency and credentialing standards described at case-management-certification-requirements. All classification boundaries reflect published source definitions — not editorial inference.
