Billing tips
Verify that at least four distinct views were obtained and documented in the radiology report before billing 72110; if only 2-3 views, bill 72100 instead
Impact: Prevents upcoding denials and potential fraud allegations; correct code selection between 72100 ($38-42) and 72110 ($50.46) ensures accurate reimbursement
When performed in a hospital or facility setting, ensure proper use of modifier 26 for professional interpretation to avoid claim rejection; the facility bills the technical component separately
Impact: Proper modifier usage prevents rejection and ensures correct payment split between professional and technical components
Document medical necessity clearly in the order and indication; vague reasons like 'back pain' may trigger prior authorization requirements or denials from commercial payers
Impact: Specific diagnoses and clinical correlation reduce denial rates by 30-40% and expedite payment processing
Do not bill 72110 with 72020 (single view spine) on the same date for the same anatomical region; the comprehensive study includes all views
Impact: Prevents bundling denials and NCCI edits that would result in zero payment for the add-on code
For workers' compensation and personal injury cases, obtain pre-authorization and verify fee schedules as reimbursement often exceeds Medicare rates by 150-300%
Impact: Can increase reimbursement from $50.46 to $125-150+ per study depending on state workers' comp fee schedule
When billing globally (without modifiers), ensure your practice owns the equipment and employs the technologist; otherwise split billing with appropriate 26/TC modifiers
