Summary & Overview
HCPCS G0520: Management of New Patient-Caregiver Dyad with Dementia, Moderate Complexity
HCPCS Level II code G0520 represents structured management of a new patient–caregiver dyad affected by dementia at moderate complexity, developed for use within the Center for Medicare and Medicaid Innovation (CMMI) models. Nationally, this code signals an emphasis on integrated care that concurrently addresses the clinical needs of the person with dementia and the support needs of their caregiver, reflecting broader policy interest in value-based, dyadic approaches to chronic condition management.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of what services this code covers, the typical clinical and operational settings for delivery, and which payers recognize or reimburse the code where information is available. The publication outlines benchmarks and policy context relevant to adoption in alternative payment models, summarizes common billing modifiers associated with similar care-management services, and provides a clinical context for how the dyadic approach differs from single-patient visits.
This briefing is intended to inform billing managers, care program leads, and policy analysts about the role of G0520 in care models focused on dementia and caregiver support, and what to expect when integrating the code into ambulatory or community-based dementia care programs.

Clinical & Coding Specifications
Clinical Context
A typical patient is an older adult recently diagnosed with moderate dementia (for example, probable Alzheimer disease) who presents with a primary caregiver (spouse or adult child) for an initial comprehensive care-management visit under a CMMI model. The visit occurs in an outpatient primary care clinic, geriatrics clinic, or memory disorders clinic and includes: structured assessment of the patient’s cognitive status, functional abilities, behavioral symptoms, medication review, caregiver needs and stress, safety and home environment review, and creation of a care plan with referrals and community resources. The clinician documents moderate complexity care planning and coordination activities, time spent communicating with the caregiver, advance care planning discussion as appropriate, and any interdisciplinary care management tasks (social work, nursing, pharmacy). Typical workflow: pre-visit chart review and medication reconciliation by nurse or care manager; face-to-face visit with physician, nurse practitioner, or geriatrician together with the caregiver and patient; documentation of assessment and care plan; arrangement of referrals (home health, neuropsychology, behavioral therapy), community supports (Alzheimer’s Association, respite services), and follow-up care; and post-visit care coordination messages or calls to caregivers and other providers.
