Apply Wound Repair Guidelines - Certified Professional Coder CPC

  1. A surgeon repairs a 6.5 cm intermediate laceration on the scalp. The wound required layered closure of the galea aponeurosis and epidermis. Which CPT® code is reported?
    Answer: 12032 CPT® 12032 covers intermediate repair of scalp, axillae, trunk, and/or extremities, 2.6-7.5 cm. A 6.5 cm intermediate repair on the scalp falls within this range. Code 12031 covers up to 2.5 cm; 12034 covers 7.6-12.5 cm; 12035 covers 12.6-20.0 cm. The scalp and the layered galea closure confirm the intermediate repair classification.
  2. A surgeon performs debridement of a wound down to the level of bone on the right heel, covering 8 sq cm. Which CPT® code covers debridement to bone for the first 20 sq cm?
    Answer: 11044 CPT® codes 11042-11047 are classified by tissue depth: 11042 = subcutaneous tissue; 11043 = muscle and/or fascia; 11044 = bone. For debridement to the bone level, 11044 (first 20 sq cm) is the correct code. Add-on code 11047 covers each additional 20 sq cm of bone debridement. The depth of debridement — not just the size of the wound — determines the code level.
  3. A patient has a 4 cm laceration on the arm that requires layered closure of the subcutaneous tissue and epidermis due to the depth of the wound. Which CPT® code range covers intermediate wound repair of the trunk and extremities?
    Answer: 12031–12037 CPT® codes 12031–12037 cover intermediate repair of the scalp, axillae, trunk, and/or extremities — including the arm. For a 4 cm laceration on the arm requiring layered closure, 12032 (2.6–7.5 cm) within the 12031–12037 range is the correct code. Codes 12041–12047 cover intermediate repair of the neck, hands, feet, and/or external genitalia — not the arm or other extremities. Codes 12001–12007 cover simple repair of scalp, neck, axillae, trunk, and extremities.
  4. A surgeon excises a 2 cm malignant lesion from the forearm and must perform an intermediate layered closure due to the depth of the excision. Which codes are reported?
    Answer: Excision code and the intermediate repair code When a malignant lesion excision requires intermediate or complex closure, the repair code is separately reported in addition to the excision code. For example, CPT® 11602 (malignant lesion excision, 1.1–2.0 cm, trunk/extremities) is reported along with the appropriate intermediate repair code (12031–12037). The layered nature of the closure goes beyond what is included in the excision code.
  5. A surgeon performs a complex wound repair on the nose involving scar revision and closure requiring more than layered sutures. The wound is 2.5 cm. Which CPT® code range covers complex repair of the eyelids, nose, ears, and/or lips?
    Answer: 13150–13153 CPT® codes 13150–13153 cover complex repair of the eyelids, nose, ears, and/or lips. Codes 13131–13133 cover complex repair of the forehead, cheeks, chin, neck, and other specific sites; 13100–13102 covers complex repair of the trunk. When the complex repair involves the nose, eyelids, ears, or lips specifically, the 13150 series is used. Complex repair requires more than layered closure — such as scar revision, debridement, extensive undermining, retention sutures, or other complex wound preparations.
  6. A surgeon performs wound debridement of a 10 sq cm infected subcutaneous wound on the foot. Which CPT® code range covers debridement of subcutaneous tissue?
    Answer: 11042-11047 CPT® codes 11042-11047 cover debridement of subcutaneous tissue (11042 for first 20 sq cm; 11045 is the add-on for each additional 20 sq cm). These codes are used for debridement down to the subcutaneous level. Codes 97597-97598 are used for active wound care management by non-physician providers; 11000-11006 cover extensive debridement of infected skin.
  7. A patient presents with two lacerations: a 3.0 cm simple repair on the scalp and a 2.0 cm simple repair on the neck. Both wounds require only single-layer closure. How is the total wound length reported?
    Answer: One code for the combined 5.0 cm total, since both are simple repairs in the same body region category CPT® wound repair guidelines state that lengths of wounds in the same classification (simple, intermediate, or complex) that are in the same anatomical grouping are added together and reported as one code. Scalp and neck are both in the "scalp, neck, axillae, external genitalia, trunk, and/or extremities" anatomical grouping for simple repair. The combined 5.0 cm is reported with a single code from the 12001–12007 range.
  8. A patient sustains burns to the entire right arm (anterior and posterior surfaces). Using the Rule of Nines for adult burn assessment, what percentage of total body surface area (TBSA) does the entire right arm represent?
    Answer: 9% The Rule of Nines divides the adult body into regions each representing approximately 9% of total body surface area: each arm = 9%; each leg = 18%; anterior trunk = 18%; posterior trunk = 18%; head = 9%; genitalia = 1%. The entire right arm (anterior and posterior) equals 9% TBSA. This calculation is essential for selecting the correct burn wound care code based on TBSA involvement.
  9. A burn patient has a full-thickness burn of the entire right leg. Using the Rule of Nines for adults, what percentage of TBSA is affected?
    Answer: 18% The Rule of Nines assigns each entire lower extremity 18% of TBSA (9% anterior + 9% posterior). A full-thickness burn of the entire right leg represents 18% TBSA. This calculation is critical for selecting appropriate burn wound care codes and determining the severity classification of the burn.
  10. A physician performs initial burn wound treatment including debridement of a partial-thickness burn covering 5% TBSA of the torso. Which CPT® code covers initial burn wound treatment with debridement, small (less than 5% TBSA)?
    Answer: 16020 CPT® 16020 covers dressings and/or debridement of partial-thickness burns, initial or subsequent; small (less than 5% total body surface area). Code 16000 covers initial treatment of a first-degree burn; 16025 covers medium burns (e.g., whole face or whole extremity, or 5% TBSA); 16030 covers large burns (greater than 1 extremity or greater than 5% TBSA). The 5% TBSA threshold distinguishes small from medium burn wound care codes.
  11. A physician closes a wound with tissue adhesive (Dermabond) only, without sutures or staples. Which CPT® repair category applies to this closure?
    Answer: Simple repair, since tissue adhesive constitutes a single-layer closure equivalent CPT® guidelines include closure with tissue adhesive (such as Dermabond) as equivalent to a simple repair. Tissue adhesive closures are reported using simple repair codes (12001–12021) based on anatomical location and wound length. The method of closure (sutures, staples, adhesive, or Steri-Strips) does not change the complexity classification — complexity is determined by the layers closed and wound condition.
  12. A patient has a 3.0 cm simple laceration on the face and a 2.5 cm simple laceration on the chin. Both require simple single-layer closure. Are these lengths added together for code selection?
    Answer: Yes — all simple repairs are combined regardless of location For CPT® wound repair, simple repairs in the same anatomical grouping are combined. The face (including the chin) falls in the "face, ears, eyelids, nose, lips, and/or mucous membranes" grouping for simple repair (12011–12018). Both the 3.0 cm face laceration and the 2.5 cm chin laceration are in this same grouping, so the lengths are added (5.5 cm total) and a single code is selected from the 12011–12018 range based on total length.
  13. A surgeon applies a negative pressure wound therapy (NPWT) device to a 50 sq cm non-healing wound on the leg. Which CPT® code covers application of a mechanically powered NPWT device?
    Answer: 97607 CPT® 97607 covers negative pressure wound therapy using a mechanically powered device for wounds with a total surface area of 50 square centimeters or less. Add-on code 97608 covers each additional 20 sq cm when the wound exceeds 50 sq cm. For a 50 sq cm wound, 97607 alone is reported. Code 97605 covers NPWT using an electrically powered device for wounds 50 sq cm or less; 97606 covers each additional 50 sq cm for electrically powered devices. The power source (electrical vs. mechanical) determines code family selection.
  14. A surgeon performs an adjacent tissue transfer (Z-plasty) to close a 3 cm defect on the cheek. Which CPT® code range covers adjacent tissue transfer or rearrangement procedures?
    Answer: 14000-14350 CPT® codes 14000-14350 cover adjacent tissue transfer or rearrangement procedures, including Z-plasty, W-plasty, V-Y plasty, and rotation flap procedures. Code selection is based on the location and size of the defect. Adjacent tissue transfer codes are reported instead of — not in addition to — standard wound repair codes when a flap or rearrangement technique is used. The primary repair code is included in the adjacent tissue transfer code.
  15. A physician performs wound closure using only Steri-Strips (butterfly adhesive strips) on a small laceration without sutures. Which coding category applies?
    Answer: The service is reported under E/M only; wound closure devices are not separately coded When wound closure is accomplished using only adhesive strips (such as Steri-Strips) without sutures, staples, or tissue adhesive, no separate wound repair CPT® code is reported. Closure with adhesive strips alone is considered part of the E/M service and is not separately billable as simple repair. Simple repair codes (12001–12021) apply when closure involves sutures, staples, tissue adhesive, or a combination — not adhesive strips alone. Coders should also verify payer-specific guidelines, as policies may vary.
  16. A surgeon needs to prepare a wound bed on a patient's calf for skin grafting by excising open wound tissue. In addition to the graft application code, which CPT® code covers surgical preparation of the recipient site for trunk, arms, or legs?
    Answer: 15002 CPT® 15002 covers surgical preparation or creation of recipient site by excision of open wounds, burn eschar, or scar, first 100 sq cm of trunk, arms, or legs. This is reported in addition to the graft application code when the recipient site requires surgical preparation. Code 15004 covers the same service for the face, scalp, eyelids, mouth, neck, ears, or genitalia. Code 15100 is the split-thickness autograft application code for trunk/extremities. Donor site harvest for standard autologous grafts is included in the graft application code and not separately reported.
  17. A patient undergoes a pedicle flap procedure to reconstruct a defect on the nose. The surgeon raises a forehead flap, rotates it to cover the nasal defect, and will divide the flap in a second stage. Which CPT® code range covers pedicle flap procedures?
    Answer: 15570–15738 CPT® codes 15570–15738 cover pedicle and myocutaneous flap procedures. Code 15570 covers formation of a direct or tubed pedicle; 15574 covers a rotation flap; 15630 covers a cross-finger flap. Forehead flap for nasal reconstruction is reported from the 15570–15576 range or the specific regional flap codes. Adjacent tissue transfer (14000 series) involves local rearrangement; pedicle flaps involve raising tissue from a distance with a blood supply bridge.
  18. A patient has an open wound that requires secondary closure (delayed primary closure) 4 days after the initial injury. Which CPT® code covers secondary wound closure?
    Answer: 13160 CPT® 13160 covers secondary closure of a surgical wound or dehiscence, extensive or complex. Code 12020 covers treatment of superficial wound dehiscence (simple); 12021 covers treatment with packing. For secondary/delayed primary closure of a wound — where the wound has been open and is subsequently closed — 13160 is used when the closure is extensive. The timing (delayed closure) and complexity drive code selection.
  19. A patient has two lacerations: a 4.0 cm intermediate repair on the trunk and a 3.0 cm complex repair on the trunk. How are these reported?
    Answer: Report the complex repair for 3.0 cm and the intermediate repair for 4.0 cm separately Wounds of different repair complexities are never combined, even at the same anatomical site. The complex repair (3.0 cm) is reported separately from the intermediate repair (4.0 cm). Each is coded based on its own complexity level and wound length within the applicable code range. Modifier -51 is appended to the lower-valued procedure.
  20. Which of the following is classified as a complex wound repair in CPT®?
    Answer: A wound requiring retention sutures, scar revision, and extensive undermining during closure Complex wound repair (13100–13160) requires more than layered closure. It includes one or more of the following: scar revision, debridement (e.g., traumatic lacerations or avulsions), extensive undermining, retention sutures, or unusual closure techniques. A wound simply requiring irrigation with single-layer closure is intermediate if layered closure or contamination is documented. Retention sutures and scar revision specifically indicate complex repair.
