M99.37
BillableOsseous stenosis of neural canal of upper extremity
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
Narrowing of the nerve canal in the arm or hand area caused by bone overgrowth, which may compress nerves and cause arm or hand symptoms.
Coding Tips
- •Clarify laterality (right, left, or bilateral) in documentation when possible
- •Ensure the stenosis is in the upper extremity and not in the cervical spine itself
