M99.50
BillableIntervertebral disc stenosis of neural canal of head region
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
Narrowing of the nerve channel in the head caused by a bulging or degenerating intervertebral disc, which can compress nerves and cause headaches or neck symptoms.
Coding Tips
- •Verify the stenosis is caused by intervertebral disc pathology, not other causes like bone spurs
- •Consider coding associated symptoms like radiculopathy if present
