Clinical & Coding Specifications
Clinical Context
A 45-year-old patient presents to an outpatient dermatology clinic with a cosmetically bothersome, stable hypertrophic scar on the cheek from a prior laceration. Conservative measures have been tried and the patient requests a minimally invasive resurfacing procedure to improve surface irregularity and texture. The provider evaluates the lesion, documents informed consent, photographs the area, and confirms no active infection or contraindicating medical conditions. On the day of service the patient is prepped, topical or local anesthesia applied as appropriate, and the provider performs a single lesion abrasion using a specialized dermabrasion device to lightly sand the surface of the skin. Hemostasis is achieved, wound care instructions are reviewed, and a follow-up visit is scheduled to assess healing and outcomes.
