Billing code 73630: Foot X-rayMedicare rate & RVUs

Medicare pays $34.07 for 73630 nationally in the office. Local office rates run $29.84–$46.64.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 73630 covers

This study images the foot in at least three distinct projections, typically dorsoplantar (AP), oblique, and lateral, and may include weight-bearing views when alignment matters. It is ordered for suspected metatarsal, Lisfranc, or midfoot fractures, hallux valgus and other deformities, diabetic foot ulcers with possible osteomyelitis, arthritis, foreign bodies, and surgical planning or follow-up. Podiatrists and orthopedic practices often perform it in the office; emergency departments, urgent care centers, and hospital outpatient imaging departments also perform it. A radiologist or treating physician interprets the images.

Select this code when at least three distinct foot views are obtained; a two-view series falls under the limited foot code. Documentation should identify the views obtained and include a written interpretation of the findings. The professional component covers interpretation and is reported with modifier 26; the technical component covers equipment and staff and is reported with modifier TC. Billing without either modifier claims the global service when the billing entity furnishes both components. When both feet receive complete studies, report each side with RT and LT; CMS pays each side at full value.

How to choose

73620Foot X-ray

73620 covers two foot views; 73630 requires at least three distinct views. Count the projections performed and documented, not the number of images ordered.

73610Ankle X-ray

73610 is a complete ankle series centered on the ankle joint. Choose 73630 when the images constitute a complete foot series rather than dedicated ankle views.

73650Heel X-ray

73650 is for dedicated calcaneal views. A routine complete foot series that shows the heel is still 73630.

73660Toe X-ray

73660 is used for a dedicated toe study. Toe structures visible on a complete foot series alone do not support reporting an additional toe study.
