What 28400 covers

This service covers nonoperative treatment of a heel bone fracture when the treating clinician manages the fracture without manipulating it to change its alignment. An orthopedic surgeon or podiatrist may provide care in an office, emergency department, or outpatient setting. Treatment commonly includes immobilization in a cast or boot and planned clinical and imaging follow-up. The key distinction is the treatment performed, not simply whether the fracture is displaced on imaging.

Report the code when the documented plan and service support closed fracture care without manipulation. The record should identify the calcaneal fracture and show that manipulation or fixation was not performed. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are paid at 50%. For bilateral treatment with modifier 50, payment is 150%. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.
