Learn about HCPCS Code G0180 for home health certification, including Medicare-covered requirements and documentation tips.

Use Code

## **What is physician certification for home health services?** Physician certification is a Medicare requirement that ensures patients qualify for home health services under a home health agency (HHA). Using HCPCS code G0180, the physician or allowed practitioner (such as nurse practitioners, physician assistants, or clinical nurse specialists) documents the patient's status, confirms a face-to-face encounter, and signs the home health plan of care. This initial certification covers one certification period and must include the first and last dates, the date physician signed, and the reports of patient status required for covered home health services such as skilled nursing, physical therapy, or occupational therapy. In some cases, it also applies to hospice care supervision or when patients transition from skilled nursing facilities or nursing home facilities. The certification verifies that skilled services are medically necessary, that the care plan oversight services (CPO) will be periodically reviewed, and that the same physician or allowed practitioner continues recertification when needed.

## **Documentation requirements** Key documentation requirements include: - **Face-to-face encounter** - Evidence that the patient had a qualifying encounter related to the need for home health services. - **Plan of care (POC)** - The initial home health plan of care must be signed and dated by the physician or non-physician practitioner. It should outline the skilled services required (e.g., nursing, physical therapy, occupational therapy). - **Certification period** - Documentation must specify the first and last dates of the certification period, as well as the date the physician signed the certification. - **Medical necessity** - The notes should show why skilled services are required and that the patient is homebound as defined by Medicare. - **Continuity of care** - Records must confirm that the same physician or practitioner will oversee recertification (when billed with G0179) and ongoing care. - **Time spent** - Physicians should document the time and work involved in reviewing reports, patient status, and coordinating care, since this justifies billing under G0180. Incomplete and missing documentation, such as failing to record the face-to-face encounter or omitting the certification dates, is one of the most common reasons for denied claims.

## **Billing requirements** When billing for G0180, it’s essential to follow CMS guidelines to ensure compliance and reimbursement. The G0180 CPT code description specifies that this service covers the certification of a patient’s eligibility and need for Medicare-covered home health services. Providers should confirm that the patient requires home health certification due to a skilled need, such as nursing care, therapy, or ongoing monitoring. Documentation must clearly establish the patient’s condition and the plan of care. Note that hospice services cannot overlap with home health certification under G0180. If a patient elects hospice, home health claims are no longer payable. Always verify dates of service, ensure timely filing, and append the correct provider signature to avoid claim denials.

## **Other relevant codes** - **G0179** – Recertification of home health services required when the patient has already received services for at least 60 days. - **G0181** – Physician supervision of a patient under Medicare-covered home health or hospice services, involving 30 minutes or more per month of care plan oversight. It includes a review of reports, phone calls with other providers, and modifications to the plan of care. These codes serve complementary roles: - Use **G0180** for initial home health certification (new episode or after 60+ days break - Use **G0179** for recertification after the first 60-day episode if services continue. - Use **G0181** for the monthly oversight of patient’s care plan (30+ minutes), for patients on home health or hospice services.

Frequently asked questions

Use G0180 when the patient hasn’t received Medicare home health services in the last 60 days, and a physician certification is required to start a new episode.

No. They are mutually exclusive, representing distinct scenarios (initial certification vs. recertification following continued services).

Providers must include a signed and dated certification (e.g., CMS-485 or its successor form), confirmation that the patient has not received Medicare-covered home health services in the past 60 days, the clinical justification for home health care, review of the OASIS assessment, and evidence of communication with the home health agency.
