ICD-10-CM Codes›I00–I99›I60-I69›I67
- Billable — Valid for Submission
- CC — Complication or Comorbidity
- Chronic Condition
I67.89 is a billable ICD-10-CM diagnosis code for other cerebrovascular disease. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 61 through 63, 69. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 182 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Other and ill-defined cerebrovascular disease.

Brain Diseases
Your brain is the control center of your body. It controls your thoughts, memory, speech, and movement. It regulates the function of many organs. It's part of your nervous system, which also includes your spinal cord and peripheral nerves. The nervous system sends signals between your brain and the rest of the body.

Questions About I67.89Overview
What is the ICD-10 code for other cerebrovascular disease?
The ICD-10-CM code for other cerebrovascular disease is I67.89 (sometimes written as I6789). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is I67.89 (Other specified cerebrovascular diseases) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other cerebrovascular disease on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does I67.89 group to?
When other cerebrovascular disease is the principal diagnosis on an inpatient stay, it groups to MS-DRG 69, 61, 62, 63, with relative weights from 0.7962 to 2.7211 depending on complications. Higher weights mean higher Medicare reimbursement.
Is I67.89 a CC or MCC?
CMS lists I67.89 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 182 closely related codes in its exclusion list.
Can I67.89 be reported with a code from I63.2?
Not as a rule. The Excludes1 note at I67, which applies to I67.89, lists "Occlusion and stenosis of precerebral artery causing cerebral infarction (I63.2-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
