Summary & Overview
CPT 73610: Ankle X‑ray, Three or More Views
CPT code 73610 represents a standard diagnostic radiology service: three or more X‑ray views of the ankle. Nationally, this code is a common frontline imaging service used to assess acute injury, suspected fracture, and sources of ankle pain. It is widely performed across outpatient imaging centers, hospital radiology departments, and emergency settings, making it a high‑volume item in musculoskeletal imaging and emergency care workflows.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for ordering an ankle series, typical sites of service, and operational considerations that affect utilization and billing. The publication summarizes common modifier usage where applicable, typical payer coverage patterns, and how this code fits into related imaging workflows. It also highlights benchmarking topics such as utilization frequency, site‑of‑service distribution, and coding accuracy considerations that impact claim adjudication and billing consistency.
This material is intended for revenue cycle managers, radiology department leaders, and policy analysts seeking a clear, nationally focused summary of CPT code 73610, its clinical purpose, and the payer landscape relevant to routine ankle radiography.
Billing Code Overview
CPT code 73610 describes a radiologic procedure consisting of three or more X‑ray views of the ankle joint to evaluate suspected fracture, swelling, or unexplained pain in the ankle region. The examination captures multiple projections to visualize bony alignment, joint spaces, and potential acute or chronic osseous injury.

Clinical & Coding Specifications
Clinical Context
A 28-year-old recreational soccer player presents to the urgent care clinic after twisting the right ankle during a game. The patient reports immediate pain, swelling, and difficulty bearing weight. The clinician performs a focused musculoskeletal exam noting lateral ankle tenderness over the distal fibula and anterior talofibular ligament region, ecchymosis, and decreased range of motion. To evaluate for fracture, dislocation, and assess for acute soft-tissue swelling that may alter management, the clinician orders radiographic imaging of the ankle.
The radiology technologist performs an ankle series obtaining three or more radiographic views (typically anteroposterior, lateral, and mortise) with the patient seated or standing as tolerated. Images are reviewed by the interpreting radiologist, who documents findings such as fractures, joint alignment, and presence of effusion. Results guide immediate management (immobilization, referral to orthopedics, or conservative care). Typical site of service is an outpatient imaging center, urgent care, emergency department, or physician office with radiography capability. The service type is diagnostic radiography of the ankle using multiple views to evaluate for fracture, swelling, or source of pain.
