Quick Explanation
This denial indicates that the payer has determined the cardiac catheterization procedure was not medically necessary based on the clinical documentation submitted. It typically occurs when there is insufficient evidence of prior non-invasive testing, objective findings of ischemia, or documented refractory symptoms to justify an invasive diagnostic or therapeutic cardiac catheterization.
Common Causes for CARD03
Denials with code CARD03 typically happen for the following specific reasons:
- Lack of documented prior non-invasive cardiac testing, such as a stress test, echocardiogram, or coronary CT angiography, showing ischemia.
- Clinical documentation failing to demonstrate that the patient has persistent, refractory symptoms despite guideline-directed medical therapy (GDMT).
- Failure to meet specific Local Coverage Determinations (LCDs) or National Coverage Determinations (NCDs) criteria for diagnostic cardiac catheterizations.
- Absence of documented high-risk clinical indicators, such as unstable angina, acute coronary syndrome, or life-threatening arrhythmias, which would bypass the need for prior non-invasive testing.
How to Prevent CARD03 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Verify that the patient's clinical indications align with the payer's medical necessity criteria (e.g., InterQual or Milliman Care Guidelines) during the pre-authorization process.
- Ensure all prior abnormal non-invasive test results and conservative management trials are clearly documented and attached to the scheduling order.
- Utilize EHR clinical decision support templates that prompt physicians to document the NYHA functional class, Canadian Cardiovascular Society (CCS) angina classification, and failed medications.
- Conduct regular audits against Medicare NCD 20.9 (Suffocation and Cardiac Catheterization) and local MAC policies to ensure billing compliance before claim submission.

Denial Code: CARD03 - Cardiac catheterization not warranted
Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code CARD03: "Cardiac catheterization not warranted".
We are appealing the denial of the cardiac catheterization procedure (CPT code) as not clinically warranted. In accordance with the ACC/AHA/SCAI Appropriate Use Criteria for Diagnostic Catheterization, the procedure was medically indicated as the patient presented with symptoms refractory to guideline-directed medical therapy and a prior high-risk non-invasive stress test performed on [Insert Date] which demonstrated significant reversible ischemia. The medical necessity is further supported under CMS National Coverage Determination (NCD) guidelines, as the patient's clinical presentation warranted definitive diagnostic evaluation to guide subsequent revascularization decisions. We have enclosed the complete clinical notes, stress test reports, and medication history, and we request that this denial be overturned and the claim paid in full.
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]
