What 64913 covers
This add-on describes an additional strand of processed donor nerve tissue used to bridge a peripheral nerve defect during repair. It is typically performed by a surgeon treating a nerve injury, such as a hand, plastic, or neurosurgeon, in an operating room. Multiple strands may be used when the reconstruction requires more graft material than the first strand provides.
Report 64913 for each additional strand after the first strand reported with 64912. The operative report should identify the nerve being repaired and document the allograft reconstruction and number of strands used. This is an add-on code, not a standalone service; CMS pays it within the primary procedure’s global period.

64913 billing questions
Can 64913 be reported by itself?
No. It is an add-on for additional strands and is reported with the primary nerve allograft repair, 64912.
How many units should be reported?
Report one unit for each strand beyond the first strand. The operative documentation should support the number of additional strands used.
When should 64912 be used instead?
64912 reports the first nerve allograft strand for the repair. Use 64913 only for each additional strand in that reconstruction.
What documentation supports 64913?
The operative report should describe the nerve repair using allograft and state how many strands were placed, so the additional strands can be distinguished from the first.
How does 64913 relate to the primary procedure’s global period?
CMS treats 64913 as an add-on paid within the primary procedure’s global period.
