CPT Code Overview
CPT code 12034 describes the layer closure of wounds on the scalp, axillae, trunk, and/or extremities (excluding hands and feet) for wounds measuring 7.6 cm to 12.5 cm. This procedure is classified as a surgical repair (closure) procedure within the integumentary system. The typical site of service for this code is the office setting (POS 11), where physicians perform intermediate wound repairs to restore skin integrity and promote healing.
Clinical & Coding Specifications
Clinical Context
A patient presents to the office with a laceration on the trunk, scalp, axilla, or extremity (excluding hands and feet) that measures between 7.6 cm and 12.5 cm in length. The wound is assessed and determined to require intermediate (layered) closure due to involvement of subcutaneous tissues, but not extensive enough for complex repair. The provider, typically a surgery, family medicine, or dermatology physician, performs a layered closure using sutures to approximate the wound edges and restore tissue integrity. The procedure is performed in an office setting, and documentation includes the wound location, size, and technique used for closure.
