Clinical & Coding Specifications
Clinical Context
A typical patient is an adolescent or adult presenting with cosmetic deformity, functional impairment, or recurrent infections due to macrodactylia of one or more digits of the hand. The patient often reports progressive enlargement of the affected digit(s), pain with use, difficulty with fine motor tasks, interference with fit in gloves, or recurrent skin breakdown. Evaluation includes history, focused hand and neurovascular exam, and radiographs (hand X-rays) to assess bone and soft-tissue overgrowth; MRI may be obtained to delineate soft-tissue hypertrophy if surgical planning requires it.
Surgical workflow begins with preoperative consultation by a hand surgeon (plastic or orthopedic hand specialist). The procedure 26590 is performed under regional block or general anesthesia in an ambulatory surgical center or hospital outpatient setting. Intraoperative steps commonly include incision, debulking of excess soft tissue, possible osseous contouring or partial phalangectomy, preservation or reconstruction of neurovascular bundles and tendons, and layered wound closure. Postoperative care includes dressing, immobilization in a splint, pain control, early wound checks, and referral to hand therapy for range-of-motion and scar management. Typical billing reflects the primary procedure 26590 and may include appropriate modifiers for bilateral procedures, assistant surgeon, reduced services, or professional component as clinically applicable.
