What this code actually is

CPT 11720 is a procedure code — debridement of nails, 1–5. Procedures frequently get bundled with related codes (E/M on the same day, a closure code with the underlying procedure, contrast with the imaging) — look for modifier -25 (significant separate E/M) or modifier -59 (distinct procedural service) on the bill, and ask whether they're justified. If multiple procedure lines on the same date should have been billed as a single bundled code, that's a common source of overcharges.
