Summary & Overview
HCPCS G0524: Management of Dementia Patient-Caregiver Dyad, Low Complexity
HCPCS Level II code G0524 denotes management of an established patient-caregiver dyad with dementia at low complexity, specified for use in the Centers for Medicare & Medicaid Innovation (CMMI) model. The code captures targeted care-management interactions that address both clinical and caregiver needs, and it matters nationally as health systems scale dementia care models and measure caregiver-centered outcomes. Clear coding of dyad-focused management supports program evaluation, care coordination, and resource planning for dementia services across payers.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of billing context for G0524, a summary of typical sites of service and clinical intent, and national benchmarking where available. The publication also outlines policy considerations relevant to value-based and CMMI-aligned programs, and explains how G0524 integrates into ambulatory care pathways for dementia management.
This briefing is intended to inform coding, administrative planning, and payer-contract discussions by clarifying the clinical focus of the code, common payer coverage patterns, and areas where institutions may need to align documentation and workflows to support dyad-centered care management.

Clinical & Coding Specifications
Clinical Context
A home-based memory care nurse practitioner performs a structured care-management visit for an established patient with Alzheimer disease and the primary family caregiver. The encounter focuses on care coordination, medication reconciliation, brief assessment of cognition and function, review of safety (falls, driving, wandering), caregiver stress, and development of a low-complexity care plan aligned to the practice’s chronic care management and CMMI reporting requirements. The patient is stable on current therapy, requires assistance with activities of daily living, and the caregiver requests guidance on behavioral strategies and community resources. The visit is typically documented as a 20–30 minute focused session, occurs in the patient’s residence or outpatient clinic, and supports population health metrics and care transitions. Documentation includes identification of the patient-caregiver dyad, care goals, problem list updates, brief clinical assessment, medication list, interventions provided (education, referral), and time spent on care management tasks.
