Summary & Overview
HCPCS G2001: Post-Discharge In-Home Visit for New Patient
HCPCS Level II code G2001 represents a brief, 20-minute in-home visit for a new patient following discharge from an inpatient facility and is designated for use within Medicare-approved CMMI models. This code supports transitional care by enabling a post-discharge assessment and early follow-up in a patient’s residence or institutional living setting within 90 days of discharge, with a limit of up to nine visits per beneficiary during that period. The code matters nationally as policymakers and payers focus on reducing readmissions, improving care transitions, and aligning payment models with value-based care efforts.
Key payers covered include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the service intent and appropriate sites of service, plus national-level context on why post-discharge home visits are prioritized in alternative payment and care models. The publication will also provide benchmarks and coding guidance where available, summarize relevant policy developments affecting model-based home visit payments, and offer clinical context about when brief post-discharge in-home visits are typically used. Data not available in the input will be identified as such in the detailed sections.

Clinical & Coding Specifications
Clinical Context
A typical patient is an older Medicare beneficiary recently discharged from an inpatient hospital stay for acute exacerbation of congestive heart failure. Within 48–72 hours after discharge, a home health clinician (physician, nurse practitioner, physician assistant, or qualified clinician participating in a Medicare-approved CMMI model) schedules a brief in-home visit of approximately 20 minutes to assess the patient’s clinical stability, reconcile medications, confirm follow-up appointments, evaluate wound or IV access status if present, perform basic vital signs and weight checks, and provide brief education and care coordination. The visit is furnished at the beneficiary’s place of residence, which may be a private home, assisted living facility, domiciliary, rest home, or nursing facility, and must occur within 90 days of the inpatient discharge. The workflow typically includes: a referral from the discharging hospital or care transition team; verification of patient eligibility under the CMMI-approved model; scheduling and documentation of the 20-minute in-home encounter; focused assessment and problem identification; brief care plan adjustments or referrals; and communication of findings to the primary care physician or hospital transitional care team. The service is limited to a maximum of nine visits within the 90-day post-discharge window and is intended for post-discharge transitional support rather than comprehensive home health care.
