Free 2026 Cardiology CPT Cheat Sheet

The 2026 Cardiology CPT Cheat Sheet is a 2-page reference covering cath, PCI, echo, electrophysiology, and the modifiers payers audit most. Built by AMS Solutions’ AAPC-certified coders who’ve handled cardiology billing since 1992.

This sheet covers where cardiology revenue actually leaks: missed modifier 26/TC splits on echo, and the 93016/93017/93018 component split on stress testing, missed prior authorizations on advanced imaging, and the modifiers payers audit most (25, 59, 50, LT/RT) — and when each one actually applies. Print it, post it next to the work queue, save it to your team’s coding folder. Free, no obligation.

What’s inside

• Catheterization codes 93451-93461 with bundling notes

Why your billing team will use this

Most cardiology practices we audit find $30,000-$70,000 per cardiologist per year in modifier 26/TC errors alone — recoverable revenue that’s slipping through claim by claim. This sheet flags the patterns before they cost you the money.

Cardiology’s modifier and bundling rules are where most avoidable denials start — our outsourced medical billing services work the denials and the A/R so your coders can stay on the coding.
