CPT code 11055: Lesion paring, one lesion2026 Medicare rate & RVUs

Medicare pays $70.14 for 11055 nationally in the office and $13.69 in a hospital or facility. Local office rates run $61.51–$96.47.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 11055 covers

This service removes the thickened surface of one benign hyperkeratotic lesion, commonly a corn or callus, by paring or cutting it. Podiatrists, dermatologists, and other qualified clinicians may perform it in an office or outpatient setting. The target is a localized thickened lesion, not a wound requiring tissue-depth debridement or a nail requiring trimming or debridement.

Select this code when one lesion is treated; use 11056 for two to four lesions or 11057 for more than four. Document the lesion, its location, the treatment performed, and the clinical reason for care. Medicare payment is restricted to specific circumstances, so the record must support coverage under the applicable criteria. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate because this code counts lesions rather than paired anatomy. Medicare does not pay an assistant at surgery for this service, and co-surgeon or team-surgery billing is not permitted.
