Billing tips

Always append laterality modifiers (LT/RT) to avoid claim rejections and ensure accurate anatomic documentation
Impact: Prevents automatic denials from Medicare and most commercial payers; can delay payment 20-30 days if rejected
Document the specific indication for ultrasound (media opacity, trauma, suspected pathology) in both the order and interpretation report
Impact: Reduces medical necessity denials by approximately 40-60% and supports the $81.51 reimbursement
For bilateral exams, verify payer-specific policy on modifier 50 versus two line items with LT/RT modifiers before submission
Impact: Incorrect bilateral billing can result in 50% underpayment or complete denial requiring resubmission
Ensure interpretation report includes scan type (A-scan, B-scan, or both), measurements obtained, and clinical correlation with diagnosis
Impact: Incomplete reports are the second leading cause of denials; complete documentation supports full $81.51 payment
When performed on the same day as an office visit, ensure ultrasound medical necessity is separate from the E/M service to avoid bundling
Impact: Proper separation prevents $81.51 payment from being bundled into E/M code reimbursement
Bill split/shared visits appropriately in facility settings using modifier 26 for professional interpretation to capture the applicable portion of the 2.52 total RVUs
Impact: Failure to split bill can result in complete denial in hospital settings; proper use ensures appropriate professional component payment
