Quick Explanation
This denial indicates that the payer did not find a valid physician's order or prescription on file for the billed cardiac rehabilitation services. Under CMS and commercial payer guidelines, cardiac rehabilitation requires a formal, signed referral and an individualized treatment plan from a physician prior to the initiation of therapy.
Common Causes for CARD05
Denials with code CARD05 typically happen for the following specific reasons:
- The claim was submitted without a valid, signed physician referral or prescription in the patient's medical record.
- The referring provider's name and NPI were missing or incorrectly entered in Box 17 of the CMS-1500 claim form.
- The sessions billed exceeded the quantity or duration specified in the initial physician's order without an updated prescription.
- Failure to document a qualified diagnosing practitioner's explicit prescription linking the rehab to a qualifying cardiac event (e.g., MI, CABG).
How to Prevent CARD05 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Implement a hard stop in the scheduling system that prevents booking cardiac rehabilitation sessions until a signed physician prescription is uploaded.
- Verify and populate the referring physician's details, including NPI and credentials, in Box 17 and 17b on all outgoing cardiac rehab claims.
- Establish electronic health record (EHR) alerts to track prescription expiration dates and session limits to prompt providers for timely renewals.
- Perform routine pre-billing audits to ensure that the Individualized Treatment Plan (ITP) is signed by the physician within the required timeframe.

Denial Code: CARD05 - Cardiac rehabilitation not prescribed
Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code CARD05: "Cardiac rehabilitation not prescribed".
We are appealing the denial for the cardiac rehabilitation services billed, which were denied under code CARD05 due to a perceived lack of a physician prescription. Pursuant to CMS Medicare Benefit Policy Manual, Chapter 15, Section 232, and National Coverage Determination (NCD) 20.10, cardiac rehabilitation is fully reimbursable when ordered by a qualified physician. Enclosed with this appeal is the original, signed physician prescription dated prior to the initiation of the rehabilitation program, along with the approved Individualized Treatment Plan (ITP) signed by the directing cardiologist. These documents establish that the services were fully prescribed, medically necessary, and conducted under direct physician supervision. We respectfully request that you review the attached clinical records and reverse this denial to process the claim for 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]
