2025 CPT code 64890
(Active) Effective Date: N/A Surgery - Surgical Procedures on the Nervous System Feed
Nerve graft (includes obtaining graft), single strand, hand or foot; up to 4 cm length.
Modifiers may be applicable, such as -22 (Increased Procedural Services) for unusually complex cases, or anatomical modifiers for specifying the digits of the hand or foot.
Medical necessity for this procedure must be established by documenting the functional impairment caused by the nerve damage and the expectation that the nerve graft will improve function.
The physician performs the entire procedure, including harvesting the nerve graft, preparing the recipient site, and suturing the graft in place.
In simple words: A healthy piece of nerve, less than 4 centimeters long, is taken from elsewhere in the body (usually the leg) and used to replace a damaged nerve in the hand or foot. This helps restore feeling and movement.
This code describes a procedure where a single strand nerve graft, up to 4 cm in length, is used to repair a damaged nerve in the hand or foot. The procedure involves harvesting a healthy nerve segment (often from the sural nerve in the leg), removing the damaged portion of the nerve in the hand or foot, and suturing the graft to the ends of the transected nerve.The donor nerve site is also repaired.
Example 1: A patient lacerates their finger, severing a digital nerve. A nerve graft using a segment of the sural nerve less than 4cm is performed to restore function., A patient with a neuroma in their foot undergoes excision of the neuroma and a nerve graft less than 4cm to repair the damaged nerve., A patient experiences nerve compression in their hand, leading to numbness and weakness. After decompression, a nerve graft using a segment of the sural nerve less than 4cm is necessary to repair the damaged nerve.
Documentation should include the location and length of the nerve graft, the site from which the graft was harvested, the method of nerve repair, and the reason for the procedure (e.g., trauma, neuroma).
** Code 64890 is for a single strand nerve graft up to 4 cm in length. For grafts longer than 4 cm or for multiple strand (cable) grafts, different codes apply (e.g., 64891, 64895).
