I67.9 — Cerebrovascular disease, unspecified

BillableUnspecified

Is I67.9 billable?

Yes, but I67.9 is an unspecified code. I67.9 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, I67.9 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 I67.9 — the more specific alternatives are listed below.

Which MS-DRGs does I67.9 group to?

I67.9 sits in MDC 01 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.

How is I67.9 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to I67.9. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Angiopathia, angiopathy › cerebral
  • Degeneration, degenerative › cerebrovascular
  • Depression › cerebrovascular (acute) (mental)
  • Disease, diseased › cerebrovascular
  • Failure, failed › cerebrovascular
  • Lesion › cerebrovascular (s) (nontraumatic)
  • Disease, diseased › artery › cerebral
  • Disease, diseased › brain › arterial, artery
  • Lesion › brain › vascular (s) (nontraumatic)
  • Lesion › cerebrovascular › degenerative (s) (nontraumatic)
  • Lesion › vascular › affecting central nervous system (s) (nontraumatic)
  • Degeneration, degenerative › brain › in › cerebrovascular disease

Excludes1 — never code together — inherited from I60-I69

The conditions below can never be reported together with I67.9 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • traumatic intracranial hemorrhage (S06.-)

Excludes1 — never code together — inherited from I67

The conditions below can never be reported together with I67.9 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • Occlusion and stenosis of cerebral artery causing cerebral infarction (I63.3-I63.5-)
  • Occlusion and stenosis of precerebral artery causing cerebral infarction (I63.2-)

Use additional code — inherited from I60-I69

Report an additional code alongside I67.9 to fully describe the condition. I67.9 is sequenced first.

  • code to identify presence of:
  • alcohol abuse and dependence (F10.-)
  • exposure to environmental tobacco smoke (Z77.22)
  • history of tobacco dependence (Z87.891)
  • hypertension (I10-I1A)
  • occupational exposure to environmental tobacco smoke (Z57.31)
  • tobacco dependence (F17.-)
  • tobacco use (Z72.0)

Excludes2 — not included here — inherited from Chapter 9

The conditions below are not part of I67.9, but a patient may have both at the same time. When documentation supports it, I67.9 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 I67

The conditions below are not part of I67.9, but a patient may have both at the same time. When documentation supports it, I67.9 and the excluded code may both be reported.

  • sequelae of the listed conditions (I69.8)

How long has I67.9 existed?

I67.9 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.
