Billing tips
Bill 75891 only for the supervision and interpretation component; ensure the injection/catheterization procedure (36011, 36012) is billed separately when performed
Impact: Prevents $80-150 revenue loss from unbilled catheterization procedures that are separately reportable
Document medical necessity clearly, including specific clinical indication (suspected Budd-Chiari, pre-TIPS evaluation, etc.) to differentiate from routine portal venous phase CT
Impact: Reduces denial rate by 40-60% when clear differentiation from cross-sectional imaging is established
Verify that contrast injection, fluoroscopic imaging, and formal radiological interpretation are all documented in the medical record before billing
Impact: Missing any of these three elements results in 100% payment denial and potential audit risk
When performed with TIPS procedure (37182-37183), confirm payer-specific bundling rules as some payers include venography in the TIPS code
Impact: Prevents $120.33 overpayment recoupment during retrospective audits
Use modifier 59 appropriately when hepatic venography is performed separately from wedged hepatic venous pressure measurement (93562) on the same date
Impact: Recovers $120.33 that would otherwise be bundled/denied without proper modifier usage
For Medicare patients, ensure ABN (Advanced Beneficiary Notice) is obtained if medical necessity may not be met, particularly for repeat studies within 30 days
Impact: Protects practice from $120.33 write-off if Medicare denies as not medically necessary
