M99.59 — Intervertebral disc stenosis of neural canal of abdomen and other regions
M99.59 is a billable, specific ICD-10-CM code for intervertebral disc stenosis of neural canal of abdomen and other regions. It is valid for submission on a claim.
Risk adjustment
M99.59 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
