HCPCS T1016: Case Management, Each 15 Minutes
HCPCS Level II code T1016 denotes time-based case management, billed for each 15 minutes of care coordination, service planning, and monitoring. This code captures a broad set of non-procedural activities that support patients in community, home, or outpatient settings and is an important vehicle for compensating interdisciplinary care coordination nationally.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of how T1016 is defined and used, plus national benchmarks and policy context where available. The publication outlines payment and coding considerations, typical sites of service, and common documentation elements associated with time-based case management services. It also summarizes relevant modifier practices and payer-specific coverage trends when available.
The content is intended for billing managers, compliance officers, and clinicians involved in care coordination who need a clear, national-level reference for the use and billing of HCPCS Level II code T1016.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with multiple chronic conditions (for example, congestive heart failure, chronic obstructive pulmonary disease, and diabetes mellitus) who requires coordinated care across providers, community resources, and payors. A case manager (often a registered nurse, social worker, or licensed clinical professional) documents recurring contact time in 15-minute increments under T1016 to coordinate medication reconciliation, arrange home health services, schedule specialist appointments, and address barriers to adherence such as transportation or social needs. The workflow begins with an initial assessment, identification of goals and barriers, development of a care plan, and ongoing follow-up. Each documented 15-minute interaction (phone calls, telehealth care coordination, or face-to-face care planning) is billed using T1016 with appropriate modifier(s) when needed to indicate unusual circumstances, team-based services, or payer requirements. Typical sites of service include physician offices, outpatient clinics, community mental health centers, long-term care facilities, and patient homes when case management is delivered in home-based settings.
