Peripheral nerve surgery
About 64898: Multiple-strand extremity nerve graft over 4 cm
Reports reconstruction of an arm or leg nerve defect using multiple strands of nerve graft when the graft length exceeds 4 cm.
This procedure bridges a peripheral nerve defect in an arm or leg with multiple strands of graft arranged as cables. It may be used after traumatic nerve injury or when a segment must be removed and direct repair would not close the gap without tension. Peripheral nerve, hand, plastic, orthopedic, or neurosurgeons may perform it in an operating room. The operative report should identify the recipient nerve and extremity, explain the need for graft reconstruction, and document the number of strands and graft length.
Select this code when the graft uses multiple strands and its length is over 4 cm; the site must be an arm or leg rather than the hand, foot, head, or neck. The service has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. If other procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate for this descriptor. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

64898 billing questions
How is this code distinguished from 64897?
Both describe multiple-strand grafting for an arm or leg nerve. Choose 64898 when the graft length is over 4 cm; 64897 is for a graft under 4 cm.
Does the code describe multiple nerves or multiple graft strands?
It distinguishes the multiple-strand graft configuration, not simply the number of nerves treated. Document the graft strands and the reconstruction performed.
When is 64893 a closer fit?
64893 describes a single-strand graft for an arm or leg nerve over 4 cm. Use 64898 when the reconstruction uses multiple strands.
Can modifier 50 be used when both limbs are treated?
No. The descriptor or anatomy makes a bilateral adjustment inappropriate. The CMS rule for this code states that modifier 50 does not apply.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant surgeon or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
