Cardiac catheterization is a critical diagnostic and interventional procedure for heart disease. Insurance denials often center on whether the procedure meets clinical indications or if non-invasive testing should be done first.
Common Denial Reasons
- Non-invasive testing (stress test, CT angiography) not completed first
- Prior authorization not obtained
- Clinical criteria for catheterization not met per guidelines
- Procedure performed at non-preferred facility
When Catheterization Is Medically Necessary
Diagnostic Catheterization
- Abnormal non-invasive test results suggesting significant coronary artery disease
- Acute coronary syndrome (heart attack) — emergency, no prior auth needed
- Valvular heart disease requiring hemodynamic assessment
- Heart failure with suspected coronary etiology
Interventional (PCI/Stent)
- Significant stenosis identified on diagnostic cath
- Acute STEMI — immediate intervention required
- Failed medical management of stable angina
Appeal Strategy
- Cite ACC/AHA Appropriate Use Criteria for your specific indication
- Include all prior non-invasive test results
- Cardiologist letter explaining why catheterization was the appropriate next step
- For emergency cases, emphasize that prior authorization cannot be required
- Include symptom history, risk factor profile, and functional limitations
