K08.4 — Partial loss of teeth

Non-billable headerICD-10-CM

K08.4 is a non-billable header ICD-10-CM code for partial loss of teeth. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

complete loss of teeth (K08.1-)
congenital absence of teeth (K00.0)

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.

exfoliation of teeth due to systemic causes (K08.0)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Acquired loss of teeth, partial

Other codes that can never be billed with K08.4

These codes carry an Excludes1 note pointing at K08.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K08.4 alone.

Risk adjustment

K08.4 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 K08.4

5 child codes. Green means billable.
