What 64837 covers

This add-on represents repair of an additional non-digital nerve in the hand or foot when the surgeon also transposes that nerve. Transposition moves the nerve into a different position or tissue bed as part of the repair. It is typically performed by a hand, orthopedic, plastic, or peripheral nerve surgeon in an operating room after traumatic injury or during reconstruction when more than one nerve requires this treatment.

Report 64837 only with the primary repair code 64836 for the first nerve repaired with transposition. The operative report should identify the additional nerve and document its repair and transposition; the add-on is for another nerve, not another nerve end or a repeat repair of the same nerve. CMS classifies it as an add-on code: it is billed only with a primary procedure and its payment falls within that procedure's global period.

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.

64837 billing questions

Which primary code must accompany 64837?

Report 64837 with 64836, which represents repair with transposition of the first qualifying hand or foot nerve. The additional nerve must also be repaired with transposition.

Can 64837 be used for an additional digital nerve?

No. Code 64837 applies to additional non-digital nerves of the hand or foot; 64832 is the add-on for an additional digital nerve.

How does 64837 differ from 64835?

Both concern additional non-digital hand or foot nerves, but 64837 is for repair with transposition. Code 64835 describes an additional nerve repair without that transposition distinction.

What should the operative report document?

Identify the additional nerve and describe its repair and transposition. The record should also support the primary 64836 service for the first nerve.

Is 64837 billed as a stand-alone service?

No. CMS identifies it as an add-on code, so it is billed only with a primary procedure; payment is within that procedure's global period.
