Modifiers may be applicable. Common modifiers include 22 (Increased Procedural Services), 51 (Multiple Procedures), 59 (Distinct Procedural Service), 76, 77, 78, 79 (Repeat Procedures), LT (Left side), RT (Right side).
Medical necessity should be established by documenting the functional deficits resulting from the nerve injury and the expectation that surgical repair using a nerve graft will improve function.
The physician harvests the nerve graft, prepares the damaged nerve, attaches the graft to bridge the gap in the injured nerve, and closes the surgical sites.
In simple words: The doctor repairs a damaged nerve in your arm or leg by using a piece of nerve from another part of your body.This piece is called a graft, and it's used to bridge the gap in the damaged nerve. The graft is longer than 4 centimeters. The procedure includes taking the graft, usually from a less important nerve in your leg, and attaching it to the damaged nerve. The area where the graft is taken from is also stitched up.
This procedure involves using a single strand nerve graft, a piece of unrelated nerve, to bridge or repair a damaged nerve in an arm or leg. The graft is longer than 4 cm. The procedure includes harvesting the graft, typically from a sensory nerve such as the sural nerve, and suturing it to the damaged nerve. The harvesting site is also closed with sutures.
Example 1: A patient has a severed median nerve in their forearm following a deep laceration. A single strand nerve graft greater than 4cm is used to repair the nerve., A patient has a peroneal nerve palsy resulting in foot drop. A single strand nerve graft greater than 4cm is harvested from the sural nerve and used to repair the peroneal nerve., A patient sustained a gunshot wound to the upper arm resulting in significant damage to the radial nerve. The surgeon decides to repair the defect using a single strand nerve graft greater than 4cm in length.
Documentation should include the location and length of the nerve injury, the location the graft was harvested from, the length of the nerve graft, the type of repair performed, and any complications encountered.
