I67 — Other cerebrovascular diseases
Is I67 billable?
No — I67 is a non-billable header code. I67 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 17 billable codes beneath I67.

Excludes1 — never code together
The conditions below can never be reported together with I67 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here
The conditions below are not part of I67, but a patient may have both at the same time. When documentation supports it, I67 and the excluded code may both be reported.
- sequelae of the listed conditions (I69.8)
Excludes1 — never code together — inherited from I60-I69
The conditions below can never be reported together with I67 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.-)
Use additional code — inherited from I60-I69
Report an additional code alongside I67 to fully describe the condition. I67 is sequenced first.
Excludes2 — not included here — inherited from Chapter 9
The conditions below are not part of I67, but a patient may have both at the same time. When documentation supports it, I67 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.-)

How long has I67 existed?
I67 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.
