What 28530 covers
This code describes closed management of a fractured sesamoid without manipulating the bone fragments. Sesamoids are small bones beneath the first metatarsal head; a patient may present with pain and tenderness under the ball of the foot after an injury. Orthopedic surgeons, podiatrists, and other qualified clinicians may provide the fracture care in an office, clinic, or facility setting. The service is distinct from treatment of a toe phalanx fracture, even when symptoms are near the great toe.
Select this code when the provider documents a sesamoid fracture and closed treatment without manipulation. The record should identify the fracture site and show the treatment plan; use the manipulation code when the fragments are manipulated instead. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in one session, the highest-valued is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
