Billing tips
Always append RT or LT modifier to specify which foot was imaged, as laterality is required for proper claims processing
Impact: Prevents automatic denials and requests for corrected claims, saving 15-30 days in payment delay
Split billing with modifier 26 (professional) and TC (technical) when appropriate based on facility ownership to maximize compliant reimbursement
Impact: Ensures proper payment distribution between facility and interpreting physician; typical split is approximately 40% professional, 60% technical
Document the number of views taken in the radiology report, as some payers may require three or more views for full reimbursement or may have different codes for limited studies
Impact: Prevents downcoding to a lower-paying limited study code; maintains the full $32.99 reimbursement
Verify medical necessity with appropriate ICD-10 codes linking to trauma, pain, or specific clinical indications before ordering
Impact: Reduces denial rate by approximately 20-30% for lack of medical necessity
When billing for both feet on the same date of service, bill as two separate line items (73630-RT and 73630-LT) rather than using modifier 50
Impact: Radiology codes typically do not accept modifier 50; proper line-item billing ensures payment for both studies at $65.98 total
Ensure the written radiology report is signed and dated before claim submission to meet Medicare documentation requirements
Impact: Prevents post-payment audits and takebacks; signed reports are required for all diagnostic imaging claims
