M26.52 — Limited mandibular range of motion
M26.52 is a billable, specific ICD-10-CM code for limited mandibular range of motion. It is valid for submission on a claim.
Risk adjustment
M26.52 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.
