CPT® Code 57105

The CPT® Code 57105 refers to a procedure known as a biopsy of the vaginal mucosa that is extensive in nature and requires suture closure, including the biopsy of cystic lesions. This procedure is performed by a physician who begins by cleansing the skin and administering a local anesthetic to ensure patient comfort during the biopsy. Unlike a simpler biopsy, which is coded under CPT® 57100, the extensive biopsy represented by CPT® 57105 involves a more significant surgical intervention. In this case, the physician makes an incision in the vaginal mucosa at the site of the lesion, which may include cystic formations such as inclusion cysts, Gartner's duct cysts, or benign cystic tumors. The procedure entails the removal of a large section of abnormal tissue, which is then sent to a laboratory for pathology examination to assess the nature of the tissue. Following the biopsy, the incision is closed with sutures, indicating the complexity and extent of the procedure compared to simpler biopsy methods.
