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.

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.

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.

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.
