M26.3 — Anomalies of tooth position of fully erupted tooth or teeth
M26.3 is a non-billable header ICD-10-CM code for anomalies of tooth position of fully erupted tooth or teeth. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
- embedded and impacted teeth (K01.-)
Other codes that can never be billed with M26.3
These codes carry an Excludes1 note pointing at M26.3. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M26.3 alone.
- K01Embedded and impacted teeth
Risk adjustment
M26.3 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.
