In simple words: This code describes the stitching up of a deep cut or tear on the lip that goes through all layers of the lip and is less than half the lip's height.This is often done for injuries or after surgery.

This CPT code, 40652, encompasses the surgical repair of a full-thickness laceration or a surgically created wound on the lip.The laceration must extend through all layers of the lip, including the vermilion border, and its size is limited to a maximum of half the vertical height of the lip. The repair involves the use of sutures to close the wound, followed by dressing application.This procedure is frequently performed for wounds resulting from trauma or surgical incisions.

Example 1: A patient presents to the emergency room after a bicycle accident with a deep laceration on their lower lip, extending through the full thickness of the lip but less than half its vertical height.Code 40652 is used., During a surgical procedure to remove a lesion on a patient's upper lip, the surgeon creates a full-thickness incision up to half the vertical height of the lip to achieve adequate excision of the lesion. Code 40652 is used., A patient sustains a full-thickness laceration to the vermilion border of their lower lip during a fight, the tear extending to less than half the vertical height. Code 40652 applies.

* Thoroughly documented history of the lip injury or surgical indication.* Detailed description of the wound including its location, depth (full-thickness), size (less than half the vertical height of the lip), and involvement of the vermilion border.* Documentation of anesthesia used.* Description of the surgical technique used to repair the wound.* Indication of any complications.* Photographs of the wound (before and after repair) are helpful.

** This code is specific to lip repairs; other codes exist for repairs in different areas of the face.Always verify the precise anatomical location and dimensions of the wound to select the most appropriate code.
