The medical record should support the need for surgical intervention rather than alternative treatments.

IMPORTANT (For excision of mucous lesions, see 40810-40816)

In simple words: The doctor removes a V-shaped piece of tissue from your lip to get rid of a lesion or defect.They then sew the edges together in a straight line.

The provider performs a V-shaped excision on the lip and closes the incision with a primary direct linear closure. This procedure is typically done to remove a lesion or defect.After prepping and anesthetizing the patient, the provider excises a V-shaped wedge of tissue around the affected area on the lip. The wound edges are then sutured together in a straight line to achieve a direct linear closure.

Example 1: A patient presents with a benign lesion on their upper lip. The provider performs a V-excision of the lesion and closes the defect with a direct linear closure using 40520., A patient has a small basal cell carcinoma on their lower lip. A V-excision is performed to remove the cancerous tissue, and the incision is closed with a direct linear closure, billed as 40520., Following a traumatic injury, a patient has a jagged laceration on their lip. The provider trims the irregular edges of the wound into a "V" shape and repairs it with a direct linear closure using code 40520.

Documentation should include the location and size of the lesion or defect, the method of excision (V-excision), the type of closure (direct linear closure), and any complications encountered. Photographs may also be beneficial.
