Billing tips

Always verify whether you own the equipment or are billing in a facility setting to determine if modifier 26 is required
Impact: Billing global code in facility setting causes overpayment recovery; using modifier 26 correctly ensures the $215.43 professional component is properly allocated
Document the specific mechanical technique used (urokinase, snare retrieval, balloon angioplasty of fibrin sheath) and contrast administration to support medical necessity
Impact: Prevents 15-25% of denials for insufficient documentation and supports appeals when payers question necessity
Bill 75901 separately from catheter placement codes (36568-36571) only when performed on different dates or completely separate catheters
Impact: Avoids NCCI bundling edits that result in automatic denial; when appropriately separate, captures additional $215.43
Link to appropriate ICD-10 codes indicating catheter complication (T80.2XXA for catheter infection complications, T82.898A for other vascular device complications)
Impact: Specific complication codes reduce denial rate by 30-40% compared to using only symptom codes
For Medicare patients, ensure procedure meets LCD requirements for interventional radiology including pre-procedure imaging documentation of obstruction
Impact: Compliance with LCD criteria prevents post-payment audits and recoupment of the full $215.43 payment
When performed bilaterally or on multiple catheters in same session, append modifier 50 or bill with units as appropriate per payer policy
Bilateral modifier typically yields 150% payment ($323.15 total) versus single side when properly documented
