Episode notes
Use Modifiers Only When Justified
- Use modifiers correctly: apply 59/XU/XS/XP only when NCCI rules permit and supporting documentation exists.
- Avoid blanket use of 59 on every code to prevent audits.
Modifier Choice Changes Who Gets Paid
- Complex or partnered procedures require correct modifier selection to split payment fairly.
- Not all codes qualify for assistant or co-surgeon modifiers; check payer lists.
Differentiate Thrombus From Fibrin Sheath
- Document thrombus presence when billing thrombectomy and distinguish fibrin sheath disruption from true thrombectomy.
- Use unlisted codes appropriately for fibrin-sheath-only procedures.
