Clinical records must clearly document medical necessity and an explicit rationale for why removal is not cosmetic when billing CPT 17106-17108.
Coding and billing guidance must be used with the associated Local Coverage Determination; coverage details for CPT 11055-11057 are delineated in the Medicare Internet-Only Manual and should be followed for claims.
Maintain all documentation in the patient's medical record and make it available to the contractor upon request; every page must be legible and include patient identifiers (complete name, dates of service).

Removal of benign skin lesions billed with CPT 17106, 17107, or 17108 is covered only when clinical records document medical necessity and explicitly state why the procedure is not cosmetic.
Treatment of hyperkeratotic lesions (e.g., corns and calluses) billed with CPT 11055, 11056, or 11057 is covered as described in the Medicare Internet-Only Manual.
Peripheral nerve blocks are covered when they meet the reasonable and necessary requirements specified in LCD L33933.
Peripheral nerve block is reasonable when the patient's pain appears due to a classic mononeuritis but neuro-diagnostic studies fail to provide a structural explanation.
Peripheral nerve blocks are reasonable for peripheral nerve injuries/entrapment or extremity trauma that lead to complex regional pain syndrome (CRPS).
Selective peripheral nerve blockade is reasonable diagnostically when the clinical picture is unclear to isolate the specific pain source.
