Quick Explanation
Denial code H20 indicates that a claim for services requiring a formal Plan of Care (POC), such as physical therapy, occupational therapy, speech-language pathology, or home health services, was submitted without the necessary physician certification. Under Medicare and commercial payer guidelines, a physician or eligible non-physician practitioner must sign and date the POC within established timeframes to certify that the services are medically necessary. Without this valid, dated physician certification on file, payers will deny reimbursement for the rendered care.
Common Causes for H20
Denials with code H20 typically happen for the following specific reasons:
- The Plan of Care was not signed or dated by the certifying physician or allowed non-physician practitioner.
- The physician's signature was obtained after the required regulatory timeframe, such as Medicare's 30-day certification window from the start of care.
- The Plan of Care was certified by an unauthorized provider type or a clinician not recognized under the payer's credentialing guidelines.
- The documented Plan of Care lacked essential certified elements, such as treatment frequency, duration, specific modalities, or measurable functional goals.
How to Prevent H20 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Implement an automated electronic health record tracking system to monitor outstanding Plan of Care documents and flag those requiring physician signatures prior to claim submission.
- Secure the physician's dated signature on the Plan of Care within 30 days of the initial evaluation or initiation of therapy.
- Perform internal pre-billing audits to verify that every Plan of Care contains all required components, including diagnosis, treatment frequency, duration, and a valid digital or handwritten physician signature.
- Educate administrative and clinical staff on Medicare Benefit Policy Manual guidelines regarding acceptable signature formats and certification timelines.

Denial Code: H20 - Plan of care not physician-certified
Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code H20: "Plan of care not physician-certified".
We are appealing the denial of this claim under code H20 (Plan of care not physician-certified). In accordance with the CMS Medicare Benefit Policy Manual, Chapter 15, Section 220, outpatient therapy services must be performed under a certified plan of care established and periodically reviewed by a physician or allowed non-physician practitioner. Attached to this appeal, please find the fully executed Plan of Care for the patient, which includes the physician's dated signature certifying the medical necessity of the services. This documentation clearly outlines the treatment diagnosis, specific modalities, frequency, duration, and long-term goals, meeting all regulatory certification standards. Because the required physician certification was active and valid for the dates of service billed, we respectfully request that you reverse this denial and process the claim for immediate payment.
Attached please find:
1. A copy of the original claim.
2. The relevant medical records supporting the service.
3. [Any other supporting documents].
We respectfully request that you reprocess this claim for payment.
Sincerely,
[Your Name]
