M99.6
M99.6 — Osseous and subluxation stenosis of intervertebral foramina
Non-billable headerICD-10-CM
M99.6 is a non-billable header ICD-10-CM code for osseous and subluxation stenosis of intervertebral foramina. It cannot be billed on its own: choose one of the more specific child codes below.
Risk adjustment
M99.6 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.
Code to one of these instead M99.6
