Summary & Overview
CPT 27810: Closed Reduction of Bimalleolar Ankle Fracture
CPT code 27810 denotes closed reduction of bimalleolar (two-malleolus) ankle fractures performed by manipulation without open surgical exposure. This code is used for unstable ankle fractures that require realignment and immobilization, typically provided in emergency departments, inpatient hospitals, or outpatient surgical settings. The procedure is clinically significant because timely, proper reduction can restore joint alignment, reduce soft-tissue injury, and impact subsequent management including the need for operative fixation or advanced imaging.
Key payers in this national analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context for use of the code, common sites of service, and the range of payer policies that affect coverage and claims adjudication. The publication also outlines common billing considerations, typical modifiers seen with the service, and related coding issues that commonly arise with ankle fracture management.
This report is designed to inform coding professionals, revenue cycle stakeholders, and orthopedic clinicians about practical billing and policy implications for CPT code 27810, offer benchmarks and policy summaries where available, and clarify clinical scenarios in which the code is appropriately reported.
Billing Code Overview
CPT code 27810 describes closed treatment of a bimalleolar or other bi-malleolar equivalent ankle fracture by manipulation to restore bone alignment without open surgical exposure. The procedure addresses fractures involving two malleoli — typically the lateral and medial, lateral and posterior, or medial and posterior malleoli — and is performed when the fracture is unstable and requires reduction.
-
Service type: Closed fracture manipulation/reduction of the ankle (nonoperative repair)
-
Typical site of service: Emergency department, outpatient surgical center, or inpatient hospital setting where orthopedic or emergency providers perform fracture reduction and immobilization
Clinical & Coding Specifications
Clinical Context
A 42-year-old male presents to the emergency department after a fall from a ladder, reporting severe left ankle pain, swelling, and inability to bear weight. Examination and radiographs demonstrate an unstable bimalleolar ankle fracture involving the lateral and medial malleoli with displacement. The orthopaedic trauma provider performs closed reduction and manipulation of the fracture in the operating room or procedure suite under regional or general anesthesia, confirms alignment with fluoroscopy, and applies a well-padded splint or temporary external immobilization. The encounter includes pre-procedure assessment, closed manipulation of both malleoli (nonsurgical fixation), intraoperative fluoroscopic imaging to confirm reduction, post-reduction neurovascular check, and splint/cast application. Typical workflow elements include emergency evaluation, imaging (plain radiographs, possible CT for complex fractures), informed consent, anesthesia support, closed reduction/manipulation under sterile conditions, fluoroscopic confirmation, and post-procedure immobilization and discharge planning with outpatient orthopaedic follow-up.
