In simple words: The doctor takes a small sample of tissue from a deep skin problem to check for disease. This code is only used if the doctor takes extra samples from other areas on the same day.

Incisional biopsy of skin, using a sharp blade to remove a full-thickness tissue sample via a vertical incision or wedge, penetrating deep to the dermis into the subcutaneous space. This procedure obtains a tissue sample for diagnostic pathologic examination and may sample subcutaneous fat, as in panniculitis evaluation. Simple closure is usually performed but not separately reported.This code (11107) is reported in addition to 11106 for each additional lesion biopsied using the incisional technique.

Example 1: A patient presents with a large, deep ulcer on their leg. The physician performs an incisional biopsy of the ulcer (11106) and also takes an additional incisional biopsy from a smaller, suspicious area nearby (11107)., A patient has multiple suspicious skin lesions. The physician performs an incisional biopsy on the largest lesion (11106), then performs additional incisional biopsies on two other separate lesions (11107 x 2). , A patient presents with a deep subcutaneous nodule. The physician performs an incisional biopsy to assess for panniculitis (11106 + 11107).

** This code is an add-on code and must be reported with 11106. It is only used for additional incisional biopsies of separate lesions on the same date of service.The use of 11107 indicates that the incisional biopsy procedure was performed independently of other procedures or services on the same date.
