In 2025, proper use of the G0180 CPT code remains crucial for healthcare providers and billing professionals working with Medicare and other payers. This code plays a vital role in certifying a patient’s eligibility for home health services, making it essential to understand the most current documentation and billing rules.
Whether you’re a coder, biller, provider, or part of a revenue cycle management (RCM) team, staying compliant with updated CMS guidelines can help reduce denials and accelerate reimbursement. This guide breaks down everything you need to know about G0180 in 2025—from eligibility criteria to real-world billing tips.
What Is G0180 CPT Code Used For?
G0180 is a Healthcare Common Procedure Coding System (HCPCS) code used to bill Medicare for a physician’s or qualified healthcare professional’s certification of a patient for home health services. It covers:
- Review of patient history and current status
- Development or review of the care plan
- Establishment of the need for skilled services
- Certification that home health is medically necessary
This service is typically reported once every 60-day episode and only by the certifying physician.
2025 Updates to G0180 Billing Rules
As of January 2025, CMS introduced several clarifications regarding documentation and billing under G0180 CPT code. These updates aim to reduce claim errors and support accurate use of home health services:
- Documentation must include: clear evidence of the face-to-face encounter and necessity of home health.
- Billing window remains limited: only one G0180 may be billed per 60-day certification period, unless there’s a significant change in condition and new episode.
- Provider requirements: nurse practitioners (NPs) and physician assistants (PAs) may certify and recertify under supervision per updated CMS scope-of-practice guidance.

Who Can Bill G0180 in 2025?
Only the healthcare professional who certifies the plan of care may bill for G0180. In 2025, the following providers are allowed to report G0180:
- Physicians (MD/DO)
- Non-physician practitioners (NPPs) such as NPs, PAs, and clinical nurse specialists—if permitted by state law and Medicare scope-of-practice regulations
Ensure the certifying provider’s NPI is accurately reported on the claim to avoid billing rejections.
Common Denials and How to Avoid Them
Incorrect use of the G0180 CPT code often results in claim denials. Below are common denial reasons and strategies to avoid them:
- Missing or vague documentation: Always include a detailed care plan, face-to-face encounter notes, and the patient’s need for skilled care.
- Duplicate billing: Do not bill G0180 if it was already submitted within the same 60-day episode unless a new certification is clearly documented.
- Unqualified provider: Ensure the certifier meets Medicare’s provider eligibility requirements.

When Not to Use G0180
There are several scenarios where G0180 CPT code is not appropriate:

- If the patient was not seen face-to-face by the certifying provider within the required timeframe
- For recertifications beyond the initial episode (use G0179 instead)

Primarily, yes. Most commercial payers do not recognize G0180, but some Medicare Advantage plans may follow CMS rules. Always check the payer’s policy.

It must include the face-to-face encounter, reason for home care, the care plan, and a statement confirming the need for skilled services.
