Summary & Overview
CPT 13133: Complex Wound Repair of Face, Neck, Hands, or Feet
CPT code 13133 identifies a complex wound repair procedure for anatomically sensitive areas — including the cheeks, chin, mouth, neck, axillae, genitalia, hands, and feet — that may involve scar revision, debridement, extensive undermining, and use of stents or retention sutures in addition to layered closure. It is reported for each additional 5 cm or less beyond the initial repair. Nationally, this code captures higher-complexity soft-tissue repairs that have implications for operative planning, resource use, and reimbursement policy.
Key payers covered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise briefing on clinical context and settings where the service is performed, guidance on common billing modifiers and code reporting conventions, and coverage considerations relevant to major national payers. The publication also summarizes benchmark metrics and policy updates that affect utilization and claims processing for high-complexity wound repairs.
This summary provides clinicians, billing professionals, and policy analysts with the essential facts about what the code represents, typical sites of service, and the payer mix considered in the national overview. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 13133 describes repair of a wound located on the cheeks, chin, mouth, neck, axillae, genitalia, hands, and/or feet that may require scar revision, debridement, extensive undermining of tissues, and the use of stents or retention sutures in addition to a layered closure. The code is reported for each additional 5 cm or less of repair beyond the initial service.
-
Service type: Complex wound repair with possible scar revision, debridement, extensive undermining, and adjunctive support (stents or retention sutures).
-
Typical site of service: Ambulatory surgical centers, hospital outpatient departments, or physician office-based procedure rooms where minor to intermediate surgical repairs of the face, neck, axillae, genitalia, hands, or feet are performed.
Clinical & Coding Specifications
Clinical Context
A 34-year-old male presents to the emergency department after a bicycle accident with a 7-cm complex laceration extending across the left cheek and into the perioral tissue with notable tissue loss, contamination, and irregular wound edges. After initial triage, tetanus update, and local anesthesia, the attending plastic surgeon performs operative wound management: extensive debridement of devitalized tissue, layered closure with deep absorbable sutures and fine skin closure, substantial undermining to reapproximate tissue without tension, and placement of retention sutures and a stent to prevent contracture near the oral commissure. The initial 5 cm of repaired length is reported with 13133; an additional 2 cm is reported with an add-on code per the code descriptor if applicable. The procedure typically occurs in an outpatient surgical suite, emergency department procedure room, or operating room under local anesthesia with monitored sedation. Clinical workflow includes preoperative assessment, informed consent, wound irrigation and debridement, layered repair with possible scar revision techniques, postprocedure dressing and discharge instructions, and scheduled follow-up for suture removal and scar assessment.
