Peripheral nerve surgery
About 64859: Additional major peripheral nerve repair
Reports repair of an additional major peripheral nerve in an arm or leg, other than the sciatic nerve, during a qualifying nerve-repair operation.
This add-on represents microsurgical repair of another major peripheral nerve in an arm or leg during the same operation as a primary major-nerve repair. It is relevant when an injury, such as a traumatic laceration, affects more than one major nerve and the surgeon directly sutures each damaged nerve. The operating surgeon may be a peripheral nerve, hand, plastic, orthopedic, or neurosurgical specialist working in an operative setting.
Report 64859 only with the qualifying primary nerve-repair procedure, such as 64856 or 64857, when the operative record supports repair of a distinct additional nerve. Document the nerve’s name and location, the injury, and the repair performed; a second repair of the same nerve or multiple sutures within one repair do not establish another nerve. CMS identifies this as an add-on code: it is billed with the primary procedure, and payment falls within that procedure’s global period.

64859 billing questions
Can 64859 be billed by itself?
No. It is an add-on for an additional major peripheral nerve repair and must be reported with a qualifying primary procedure, such as 64856 or 64857.
What supports reporting an additional unit?
The record should identify a distinct additional major nerve and describe its injury and separate repair. Multiple sutures used to repair one nerve do not make it an additional nerve.
How does 64859 differ from 64858?
64859 describes repair of an additional major nerve in an arm or leg, excluding the sciatic nerve. 64858 is the specific code for repair of the sciatic nerve.
How do 64856 and 64857 differ from 64859?
64856 or 64857 reports the primary major peripheral nerve repair, with the applicable code reflecting whether transposition is performed. 64859 is added for another qualifying nerve repaired in the operation.
Can 64831 or 64834 be used for a second nerve?
Those codes describe repairs in different anatomic categories, such as a digital nerve or a nerve of the hand or foot. Use 64859 only when the additional nerve meets its major arm-or-leg nerve scope.
