Is K08.1 a billable ICD-10-CM code?

No. K08.1 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does K08.1 sit in the tabular list?

Diseases of the digestive system (K00-K95), in the block Diseases of oral cavity and salivary glands (K00-K14).

What cannot be coded together with K08.1?

K08.1 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter.

K08.1

K08.1 — Complete loss of teeth

Non-billable headerICD-10-CM

K08.1 is a non-billable header ICD-10-CM code for complete 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.

congenital absence of teeth (K00.0)
exfoliation of teeth due to systemic causes (K08.0)
partial loss of teeth (K08.4-)

Inclusion terms

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

Acquired loss of teeth, complete

Excludes2 inherited from the categories above K08.1

Also inherited, and the opposite of Excludes1: these conditions are not part of K08.1, but a patient can have both, so you may code both.

Written on K08 — Other disorders of teeth and supporting structures

dentofacial anomalies [including malocclusion] (M26.-)
disorders of jaw (M27.-)

Other codes that can never be billed with K08.1

These codes carry an Excludes1 note pointing at K08.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K08.1 alone.

K00.0Anodontia
K08.4Partial loss of teeth

Risk adjustment

K08.1 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

K08.1 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead K08.1

5 child codes. Green means billable.
