Documentation Tips
- Document indication for all cardiac studies
- Include stress test protocol and patient response
- Specify complete vs. limited echocardiography
- Document electrode placement for ECG
- Note contrast use for cardiac catheterization
Common Denial Patterns
Understanding common denial reasons helps prevent claim rejections and improves audit defense.
- Missing medical necessity documentation
- Frequency limits exceeded
- Incomplete stress test documentation
- ECG interpretation bundled incorrectly
- Prior authorization required
Frequently Asked Questions
Use modifier 26 to report only the professional component (interpretation) when the technical component is billed separately (often by the facility).
Yes. Include the protocol (e.g., Bruce), achieved METs, termination reason, and symptoms. Note pharmacologic agents if used.
Yes, when medically necessary and distinct; ensure separate indications. Avoid unbundling interpretation if already included.
Document contrast use, volume, and any imaging performed (e.g., ventriculography).
