CPT Code 13101: Repair, Intermediate, Scalp, Arms or Legs, 2.6–7.5 cm

Learn how CPT code 13101 covers intermediate layered wound repair of 2.6–7.5 cm on the trunk or extremities, including subcutaneous tissue and fascia.

Use Code

What is intermediate layered repair (2.6–7.5 cm)?

The 13101 CPT code refers to an intermediate repair of a wound on the trunk, arms, or legs measuring 2.6 to 7.5 cm in length. This surgical procedure involves layer closure of one or more subcutaneous tissue layers and the skin, often including superficial fascia, particularly when extensive undermining is required to close the wound effectively.

This complex repair is typically more involved than a simple repair (such as surface-only closure), but less intricate than a complex closure, which might involve retention sutures, deeper layers, or other procedures such as flap or graft placement. It's commonly used after excision of skin lesions, scar revision, trauma, or surgeries requiring primary closure of deeper tissues.

CPT code 13101 documentation requirements

To support proper use of CPT code 13101, healthcare providers should include:

Exact wound measurement: Must be 2.6 to 7.5 cm
Anatomic location: Limited to scalp, extremities, or trunk
Detailed layered closure: Involving subcutaneous tissue and superficial fascia
Closure technique: Materials used and extent of undermining (if applicable)
Condition of the wound: Including contamination status and cleansing performed
Patient tolerance: Include anesthesia type, response, and any signs of discomfort or pain

For accurate billing and compliance, importance of documenting the layered repair nature of the procedure is a must.

CPT code 13101 billing guidelines

To ensure proper coding and reimbursement for intermediate layered wound repairs, it's important to follow these CPT code 13101 billing guidelines.

Report CPT code 13101 for each intermediate wound repair within the 2.6–7.5 cm range.
If the wound is larger than 7.5 cm, report 13102 for each additional 5 cm.
Do not aggregate wound lengths across different anatomical areas.
Avoid combining with simple or complex repair codes on the same wound.
Supplies, local anesthesia, and instruments are included in the code.
Applicable when the surgeon performs the service as part of primary closure.

Anesthesia and suture materials are included in the code.

Frequently asked questions

An intermediate repair involves layered closure of the skin, subcutaneous tissue, and possibly the superficial fascia, usually after lesion removal or traumatic injury. It requires more effort than a simple closure, including extensive undermining if needed.

No. While more involved than simple repair, CPT code 13101 does not describe a complex repair. For repair of complex situations involving deep tissue, retention sutures, or flap coverage, use a complex closure code.

Yes, the 13101 CPT code can be used for scar revision when layered repair is performed and the wound is between 2.6 and 7.5 cm. Be sure to document the extent of closure and layers involved.
