What 37780 covers

This service involves surgically revising a previously treated vein in the leg, often when varicosities recur or persist after prior ligation. A vascular surgeon or other qualified surgeon may identify and revise the affected vein, with ligation, division, or excision as needed. These procedures are generally performed in an operating-room setting; the operative report should identify the prior treatment and the vein or recurrent disease addressed.

Report the code for revision of the previously treated leg vein, rather than for primary treatment of a new varicose-vein cluster. Documentation should support the recurrent or residual condition and describe the revision performed. The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care. For bilateral surgery, modifier 50 is paid at 150%. When multiple procedures occur in one session, the highest-valued procedure is paid in full and others at 50%. Assistant-at-surgery payment is barred; co-surgeons require supporting documentation, and team surgery is not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

37780 billing questions

When is 37780 reported instead of 37785?

Use 37780 for revision of a previously treated leg vein. Code 37785 describes treatment of a varicose-vein cluster through a single incision, rather than revision of a previously ligated vein.

What documentation supports reporting 37780?

The operative report should establish the prior vein treatment, the recurrent or residual problem, and the revision performed. Identify the affected leg and vein or varicosity addressed.

How is bilateral revision reported?

For bilateral surgery, report modifier 50. CMS pays the bilateral procedure at 150%.

What postoperative care is included?

The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care.

Can an assistant surgeon or co-surgeon be reported?

Assistant-at-surgery payment is barred for this code. Co-surgeons are paid only when supporting documentation is provided; team surgery is not permitted.

How does CMS handle multiple procedures in the same session?

The highest-valued procedure is paid in full, and other procedures are paid at 50% when performed in the same session.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
