What 64778 covers

This add-on represents excision of a neuroma from an additional digital nerve in a finger or toe. A hand, orthopedic, plastic, or podiatric surgeon may perform the work in an operating room when a patient has painful neuromas involving more than one digital nerve, such as after nerve injury or prior surgery. The surgeon identifies and removes the additional affected nerve lesion as part of the operative treatment.

Report 64778 only with the primary digital nerve neuroma excision code, 64776, for an additional nerve treated during the same operative session. The operative note should identify the hand or foot, the distinct digital nerves treated, and the neuroma excised at each site. CMS classifies 64778 as an add-on code: it is billed only with a primary procedure and paid within that procedure’s global period.
