Why MA Plans Denies Cardiac Catheterization
Non-invasive testing not completed first
Stress test results do not meet threshold for catheterization
Stable angina without high-risk features
Know Medicare Advantage's Criteria
Medicare Advantage plans must cover all services covered by Original Medicare (CMS NCDs and LCDs) but may require prior auth. Plans use various criteria including InterQual, MCG, and proprietary guidelines.
Key policies to know:
- Must cover all services covered by Original Medicare
- Can require prior authorization not required by Original Medicare
- CMS NCDs and LCDs serve as coverage floor
- Organization determinations must be issued within 14 days (72 hours for expedited)
MA Plans's Specific Approach to Cardiac Catheterization
Applicable Policy
No specific CMS NCD for diagnostic cardiac catheterization -- covered under general Medicare benefit
How MA Plans Typically Denies This
MA plans apply their own prior auth criteria, often using InterQual or MCG. Since there's no specific NCD, they have more flexibility. Some MA plans deny catheterization for stable patients meeting only stress test criteria.
Your Strategy for This Payer
Cite ACC/AHA guidelines and Appropriate Use Criteria. Without a specific NCD, the argument is based on standard of care and clinical appropriateness. ACC/AHA guidelines carry significant weight.
Key Phrase to Use on the Call
"Diagnostic catheterization is the standard of care for this clinical presentation per ACC/AHA Guidelines, and this MA plan's prior auth criteria should align with nationally accepted clinical standards."
Building Your Medical Necessity Argument
Reference positive stress test with specific findings
Document unstable symptoms or acute coronary syndrome presentation
Note high-risk features on non-invasive testing
Cite Duke Treadmill Score or imaging results supporting catheterization
