Peripheral nerve surgery
About 64892: Single-strand limb nerve graft under 4 cm
Reports a single-strand nerve graft under 4 cm used to bridge a nerve defect in an arm or leg when direct repair is not feasible.
The surgeon bridges a gap in an arm or leg nerve by placing a single strand of nerve graft between the nerve ends. The service includes obtaining the graft. It is used when injury, resection, or another defect leaves insufficient nerve length for direct repair. Peripheral nerve, hand, plastic, orthopedic, and neurosurgeons may perform the procedure in an operating room, commonly in a hospital setting.
Select this code when the graft is a single strand, the treated nerve is in an arm or leg, and the graft length is under 4 cm. The operative report should identify the nerve and site, graft strand count and length, and why bridging was needed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate; an assistant may be paid, co-surgeons require supporting documentation, and team surgery is not permitted.

64892 billing questions
How is this code distinguished from 64893?
Both describe a single-strand graft for an arm or leg nerve. Use 64892 for a graft under 4 cm and 64893 for a graft over 4 cm.
When would 64897 be more appropriate?
64897 describes a multiple-strand graft for an arm or leg under 4 cm. This code is for a single strand.
Is obtaining the donor graft separately reportable?
Obtaining the graft is included in this service; do not separately report the graft-harvesting work as part of the same graft service.
Can modifier 50 be used for bilateral grafting?
No. CMS identifies bilateral adjustment as inappropriate for this code, so modifier 50 should not be used.
What documentation supports this code?
Document the arm or leg nerve treated, the nerve defect requiring a graft, the single-strand configuration, and graft length under 4 cm.
How does the 90-day global period affect follow-up billing?
The day-before preoperative visit and 90 days of related postoperative care are included in the 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 indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
