Hydrodissection of the Cubital Nerve
Question:
My provider is doing an in office hydrodissection of the cubital nerve. I am only finding a 64999 unlisted code. Is there a better code for this procedure?
Answer:
Selecting the correct code depends upon what and why the procedure is being performed. CPT 64718 requires a neuroplasty and/or transposition of the ulnar nerve at the elbow. If this is not being performed, then 64999 would have to be coded.
