CPT Code 13121: Complex Repair, Scalp, Arms and/or Legs, 2.6 to 7.5 cm

Yes, you can bill CPT 13121 with excision codes, but you must ensure the excision and repair are distinct procedures with proper documentation, and use modifier 59 if required to indicate a separate service.

No, layered closures are not always complex repairs. Layered closure of one or more deeper layers is characteristic of intermediate repair, while complex repair requires additional elements like scar revision, debridement, or extensive undermining beyond just layered closure.

An intermediate closure involves repairing a wound in the dermis or deeper layers and usually requires layered suturing. This technique is more complex than a superficial wound closure and is often used when both the deeper tissues and the skin need to be closed for optimal healing.

Repairing multiple layers is necessary when a laceration extends beyond the superficial wound layer and affects underlying structures such as fat, muscle, or fascia. This approach ensures each tissue layer is properly aligned and supported to reduce complications and improve cosmetic outcomes.
