M26 — Dentofacial anomalies [including malocclusion]
Non-billable headerICD-10-CM
M26 is a non-billable header ICD-10-CM code for dentofacial anomalies [including malocclusion]. It cannot be billed on its own: choose one of the more specific child codes below.
Other codes that can never be billed with M26
These codes carry an Excludes1 note pointing at M26. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M26 alone.
- M26.55Centric occlusion maximum intercuspation discrepancy
- Q18Other congenital malformations of face and neck
- Q38Other congenital malformations of tongue, mouth and pharynx
- Q67.4Other congenital deformities of skull, face and jaw
- Q75Other congenital malformations of skull and face bones
- R68.84Jaw pain
- K01Embedded and impacted teeth
Risk adjustment
M26 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 M26

Questions about M26
- Is M26 a billable ICD-10-CM code?

- Diseases of the musculoskeletal system and connective tissue (M00-M99), in the block Dentofacial anomalies [including malocclusion] and other disorders of jaw (M26-M27).
