Clinical & Coding Specifications
Clinical Context
A 42-year-old patient presents to a facial plastic surgery clinic seeking correction of a congenitally high hairline and prominent brow ridge for improved facial balance and aesthetic appearance. The surgeon evaluates the patient in clinic, reviews medical history, photographs the forehead, and documents goals and informed consent. Preoperative planning includes assessment of hairline position, forehead bone contour, skin laxity, and the need for autologous bone graft or alloplastic implant. On the day of surgery the patient receives preoperative anesthesia clearance, operative consent, and standard perioperative antibiotics. In the operating room the surgeon performs forehead contouring with bone remodeling and placement of prosthetic material or placement of an autologous bone graft to lower the brow or hairline (CPT 21138). Postoperative workflow includes immediate recovery, wound care instructions, pain management, and scheduled follow-up visits to monitor healing, manage edema, and assess cosmetic outcome. Typical site of service is an accredited ambulatory surgery center or hospital outpatient surgical suite. Common payors for authorization and claims review include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare.
