What 27780 covers

This code represents nonoperative care of a fracture in the proximal fibula, at the shaft or neck, without manipulating the fracture to change alignment. An orthopedic surgeon or other clinician managing the fracture may provide this care in an office, emergency department, or other appropriate setting. Treatment can include immobilization and monitoring of healing; the documented fracture location and treatment approach should support this level of care.

Select this code when the proximal fibular fracture is managed without manipulation, rather than with manipulation or open treatment. The record should identify the fracture site and document the treatment plan. CMS assigns a 90-day global period, including 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 others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery services are subject to a statutory payment restriction; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
