K08.50 — Unsatisfactory restoration of tooth, unspecified

BillableUnspecified

Is K08.50 billable?

Yes, but K08.50 is an unspecified code. K08.50 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, K08.50 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 K08.50 — the more specific alternatives are listed below.

Which MS-DRGs does K08.50 group to?

K08.50 sits in MDC Pre and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

Inclusion terms

Alternative wording in documentation that is classified to K08.50.

  • Defective dental restoration NOS

Excludes1 — never code together — inherited from K08.5

The conditions below can never be reported together with K08.50 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • dental restoration status (Z98.811)

Excludes2 — not included here — inherited from Chapter 11

The conditions below are not part of K08.50, but a patient may have both at the same time. When documentation supports it, K08.50 and the excluded code may both be reported.

  • certain infectious and parasitic diseases (A00-B99)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)
