What 64893 covers

A peripheral nerve surgeon uses a graft to bridge a gap in a nerve of the arm or leg when the nerve ends cannot be joined directly without tension. This reconstruction may follow traumatic nerve loss or a defect encountered during surgery. A donor nerve such as the sural nerve is a common graft source; graft procurement and placement are part of the graft service. This code distinguishes a single-strand reconstruction from a multistrand graft and applies to the arm or leg rather than the hand or foot.

Select the code from the operative report’s documented anatomic site, graft length, and strand configuration. The record should support the nerve reconstructed and the graft used to span the defect. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Do not append modifier 50; CMS identifies it as inappropriate for this descriptor and anatomy. Assistant-at-surgery payment may be made; co-surgeons and team surgery are 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.

64893 billing questions

When is this code selected instead of 64892?

Use 64893 for a single-strand graft in the arm or leg when the documented graft length is more than 4 cm. Code 64892 describes the corresponding graft length of less than 4 cm.

How does this differ from 64898?

Both describe an arm or leg graft over 4 cm, but 64893 is for a single strand and 64898 is for a multistrand graft.

Can modifier 50 be used for grafts on both sides?

No. CMS identifies modifier 50 as inappropriate for this descriptor and anatomy; report the documented graft service without that modifier.

What documentation supports the code selection?

The operative report should identify the reconstructed nerve and site, the graft length, and whether the reconstruction used a single strand or multiple strands.

Are related postoperative visits included?

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

May an assistant or co-surgeon be reported?

CMS permits assistant-at-surgery payment for this code. Co-surgeons and team surgery are not permitted.
