Billing tips

Document the specific number of toes imaged and number of views obtained (minimum 2 views required for complete exam)
Impact: Insufficient views may result in downcoding or denial; complete documentation supports the $28.14 reimbursement versus lower-paying limited study codes
Always append RT or LT modifier even when clinical context seems obvious; bilateral modifier 50 when both feet imaged
Impact: Missing laterality modifiers cause processing delays averaging 15-30 days and may trigger auto-denials requiring resubmission
Link to specific ICD-10 codes documenting medical necessity (trauma codes, pain R/O fracture, diabetic foot complications, etc.)
Impact: Generic pain codes without trauma history or specific clinical indication increase denial risk by approximately 35-40%
When billing same day as E/M service, ensure X-ray order and interpretation are separately documented in medical record
Impact: Bundling edits may apply without clear documentation showing X-ray as distinct diagnostic service; can affect both 73660 and E/M reimbursement
For comparison views of opposite foot (when ordered for clinical comparison), bill as separate bilateral service with modifier 50 if both feet actually imaged
Impact: Properly documented bilateral imaging yields $42.21 instead of $28.14; improper use may trigger audit
Verify payer-specific policies on global period restrictions post-toe surgery; some payers bundle routine post-op X-rays
Impact: Billing during global period without modifier 79 or documented complication results in 100% denial of $28.14

Frequently asked questions

What is the CPT code 73660 reimbursement rate for 2025?

The 2025 Medicare national average reimbursement for CPT 73660 is $28.14 for both facility and non-facility settings. This rate is based on 0.87 total RVUs multiplied by the 2025 conversion factor of 32.3465. Private insurance rates typically range from 110-200% of Medicare rates depending on contract negotiations.

Does CPT 73660 include X-rays of multiple toes or just one toe?

CPT 73660 covers radiographic examination of one or more toes on the same foot. Whether imaging a single toe or multiple toes on one foot, you report 73660 once per foot. For bilateral toe X-rays (both feet), append modifier 50 to indicate bilateral service.

What is the difference between CPT 73660 and 73630?

CPT 73660 is specific to toe imaging, while CPT 73630 covers complete radiographic examination of the entire foot. Code 73630 includes forefoot, midfoot, hindfoot, and ankle joint structures. Use 73660 when clinical focus is specifically on toe pathology; use 73630 for comprehensive foot evaluation. Billing both for the same foot on the same day typically requires modifier 59 and distinct clinical indications.

How many views are required for CPT code 73660?

A complete examination under CPT 73660 requires a minimum of two views, typically anteroposterior (AP) and oblique, or AP and lateral projections. Single-view toe X-rays are considered incomplete studies and should be reported with modifier 52 (reduced service), which will result in reduced reimbursement. Three or more views are included in the standard 73660 code without additional payment.

Can I bill CPT 73660 with an office visit on the same day?

Yes, you can bill CPT 73660 with an E/M service (office visit) on the same day when both are medically necessary and separately documented. The X-ray must be ordered as a diagnostic service based on findings from the examination. Ensure the radiology interpretation is separately documented from the E/M note. Some payers may apply minor reimbursement reductions, but both services are generally payable.

What diagnosis codes support medical necessity for CPT 73660?

Common supporting diagnoses include: traumatic toe fractures (S92.4xx series), toe pain (M79.67x), toe joint disorders (M20.1x-M20.5x for deformities), suspected osteomyelitis (M86.x7x), gout (M10.x7x), diabetic foot complications (E11.621-E11.622), and post-procedural follow-up (Z98.89). The diagnosis must clearly document why toe imaging is medically necessary rather than routine screening.

What are the RVU values for CPT code 73660 in 2025?

The 2025 RVU values for CPT 73660 are: Work RVU 0.13, Practice Expense RVU 0.72 (both facility and non-facility), and Malpractice RVU 0.02, totaling 0.87 RVUs. These values multiplied by the 2025 conversion factor of 32.3465 equal the $28.14 Medicare reimbursement rate.
