Non-billable headerICD-10-CM

K03.8 is a non-billable header ICD-10-CM code for other specified diseases of hard tissues of teeth. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes2 inherited from the categories above K03.8

Also inherited, and the opposite of Excludes1: these conditions are not part of K03.8, but a patient can have both, so you may code both.

bruxism (F45.8)
dental caries (K02.-)
teeth-grinding NOS (F45.8)

Other codes that can never be billed with K03.8

These codes carry an Excludes1 note pointing at K03.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K03.8 alone.

S02.5XXAFracture of tooth (traumatic), initial encounter for closed fracture
S02.5XXBFracture of tooth (traumatic), initial encounter for open fracture

Risk adjustment

K03.8 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 history

K03.8 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
