What is the 11055 CPT code?

CPT code 11055 refers to the paring or removal of a single benign hyperkeratotic lesion, such as a callus or corn, typically located on the feet or hands.

This procedure removes excess keratinized tissue to reduce pain, pressure, or skin breakdown, often performed by podiatrists or dermatologists.

It applies to one lesion only—use 11056–11057 for multiple lesions.

CPT code 11055 documentation requirements

The procedure note must include:

Location and size of the lesion
Clinical indication (e.g., pain, ambulation issues)
Instrumentation used (scalpel, curette)
Description of the lesion as benign/hyperkeratotic
Note if the lesion recurs or if the patient has contributing underlying conditions like diabetes or neuropathy.

Do note that for Medicare, you must specify the class findings to indicate severe peripheral involvement. For example, Class A is for non-traumatic amputation of the foot or integral skeletal portion thereof, Class B for absent posterior tibial pulse, while Class C is for claudication, edema, etc.
