K03 — Other diseases of hard tissues of teeth
Non-billable headerICD-10-CM
K03 is a non-billable header ICD-10-CM code for other diseases of hard tissues of teeth. It cannot be billed on its own: choose one of the more specific child codes below.
Other codes that can never be billed with K03
These codes carry an Excludes1 note pointing at K03. 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 alone.
- S02.5Fracture of tooth (traumatic)
- S02.5XXAFracture of tooth (traumatic), initial encounter for closed fracture
- S02.5XXBFracture of tooth (traumatic), initial encounter for open fracture
- S02.5XXDFracture of tooth (traumatic), subsequent encounter for fracture with routine healing
- S02.5XXGFracture of tooth (traumatic), subsequent encounter for fracture with delayed healing
- S02.5XXKFracture of tooth (traumatic), subsequent encounter for fracture with nonunion
- S02.5XXSFracture of tooth (traumatic), sequela
- K08.53Fractured dental restorative material
Risk adjustment
K03 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 K03
