Billing tips
Document all four or more views specifically in the radiology report (e.g., AP pelvis, frog-leg lateral, cross-table lateral, Judet views) to justify using 73503 instead of 73501 or 73502
Impact: Proper view documentation prevents downcoding to 73502 (2-3 views, $44.40) saving approximately $14.47 per study
Always append RT or LT modifier to indicate laterality as required by Medicare and most payers
Impact: Prevents automatic denials and resubmission delays; claims without laterality modifiers may be rejected, delaying payment 30-45 days
When billing bilateral hip X-rays with 4+ views each, bill 73503-RT and 73503-LT separately rather than using modifier 50
Impact: Many payers reimburse bilateral procedures at 150% rather than 200%, potentially reducing payment by approximately $29.44 for the second side
Verify whether the facility or professional component is being billed and append modifier 26 or TC accordingly to prevent payment recoupment
Impact: Incorrect component billing can result in 100% overpayment recoupment audits; professional component alone is approximately $23.55
Do not bill 73503 with 73501 or 73502 for the same hip on the same date of service as these are considered bundled
Impact: Prevents bundling denials and potential fraud investigations; secondary code will be denied at 100% ($44.40-$58.87 loss)
Check payer-specific policies on frequency limitations for hip X-rays; many limit routine follow-up imaging to specific intervals
Impact: Obtaining prior authorization when required prevents denials; unplanned denials average 60-90 day payment delays
