GC vs GE Modifier Cheat Sheet Latest Edition | Teaching Physician Decision Tree Primary Care Exception Documentation | Medical Coding

⭐ GC vs GE: THE TEACHING PHYSICIAN MODIFIER MAP — LATEST EDITION ⭐

Which modifier goes on a resident-involved claim, and when does the teaching physician have to be in the room? This sheet answers it with a seven-question decision tree, the Medicare presence rules service by service (visits, time-based codes, surgery, endoscopy, anesthesia, interpretations, psychiatry, telehealth), the full primary care exception — the listed codes, the six-month rule, the four-resident cap, the review duty — the documentation that survives an audit, and a dated box of what changed, including the permanent 2026 virtual-presence rule.

Every rule cites its Claims Processing Manual section or the August 2026 CMS MLN booklet. Created by a working coding and billing professional — not a generic template.
