Is K08.491 billable?

Yes, but K08.491 is an unspecified code. K08.491 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, K08.491 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting K08.491 — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from K08.4

The conditions below can never be reported together with K08.491 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

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

Excludes2 — not included here — inherited from Chapter 11

The conditions below are not part of K08.491, but a patient may have both at the same time. When documentation supports it, K08.491 and the excluded code may both be reported.
