M99.77
BillableConnective tissue and disc stenosis of intervertebral foramina 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 passages in the spine due to connective tissue and disc problems affecting the upper arm, forearm, and hand area, potentially causing arm or hand symptoms.
Coding Tips
- •This code applies to upper extremity symptoms; verify documentation indicates shoulder, arm, or hand involvement
- •Do not use this code for cervical spine stenosis without upper extremity involvement; use M99.81 instead
