What 27818 covers

Code 27818 represents closed reduction and treatment of a trimalleolar ankle fracture: a fracture involving the medial, lateral, and posterior malleoli. The physician manipulates the ankle to restore alignment without surgically exposing the fracture, then immobilizes it as part of the treatment. Orthopedic surgeons commonly perform this service in a hospital or other setting where the fracture is managed.

Choose this code when the fracture pattern is trimalleolar and manipulation is performed; a splint or cast alone does not establish that manipulation occurred. Document the fracture pattern, reduction maneuver, and resulting alignment. CMS assigns a 90-day major-surgery global period, including the day before surgery and 90 days of related postoperative care. In a same-session multiple-procedure situation, the highest-valued procedure is paid in full and other procedures at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; 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.

27818 billing questions

How does 27818 differ from 27816?

Both address closed treatment of a trimalleolar ankle fracture. Report 27818 when manipulation is performed; 27816 is the corresponding code when it is not.

How does 27818 differ from 27810?

The fracture pattern is the key distinction: 27818 is for a trimalleolar fracture, while 27810 is for a bimalleolar fracture treated with manipulation.

Can cast or splint application be billed separately?

Routine immobilization is part of the fracture treatment represented by 27818. Do not report a separate cast or splint application for that same treatment.

What documentation supports reporting manipulation?

Document the trimalleolar fracture pattern and the reduction maneuver used to restore alignment, including the result when known. A note that only describes applying a splint or cast does not establish manipulation.

How is bilateral treatment reported?

When the service is performed bilaterally, report modifier 50; CMS pays the bilateral procedure at 150%.

Can an assistant or co-surgeon be reported?

CMS applies a statutory restriction on assistant-at-surgery payment for this code. Co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
