I08.9Rheumatic multiple valve disease, unspecified

BillableUnspecified

Is I08.9 billable?

Yes, but I08.9 is an unspecified code. I08.9 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, I08.9 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 I08.9 — the more specific alternatives are listed below.

Which MS-DRGs does I08.9 group to?

How is I08.9 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to I08.9. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Disease, diseasedpanvalvular
  • Endocarditismultiple valves (chronic) (marantic) (nonbacterial) (thrombotic) (valvular)
  • Disease, diseasedvalve, valvularmultiple

Excludes1 — never code together — inherited from I08

The conditions below can never be reported together with I08.9 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • endocarditis, valve unspecified (I38)
  • rheumatic valve disease NOS (I09.1)

Excludes2 — not included here — inherited from Chapter 9

The conditions below are not part of I08.9, but a patient may have both at the same time. When documentation supports it, I08.9 and the excluded code may both be reported.

  • certain conditions originating in the perinatal period (P04-P96)
  • certain infectious and parasitic diseases (A00-B99)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)
  • congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
  • endocrine, nutritional and metabolic diseases (E00-E88)
  • injury, poisoning and certain other consequences of external causes (S00-T88)
  • neoplasms (C00-D49)
  • symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
  • systemic connective tissue disorders (M30-M36)
  • transient cerebral ischemic attacks and related syndromes (G45.-)

Excludes2 — not included here — inherited from I08

The conditions below are not part of I08.9, but a patient may have both at the same time. When documentation supports it, I08.9 and the excluded code may both be reported.

How long has I08.9 existed?

I08.9 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.

Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
