MS-DRG 066: INTRACRANIAL HEMORRHAGE OR CEREBRAL INFARCTION WITHOUT CC/MCC
MS-DRG 066 is intracranial hemorrhage or cerebral infarction without cc/mcc, in MDC 01 (a medical DRG), at the without-CC/MCC level. Its FY2027 relative weight is 0.6770, so a case here pays less than the average Medicare inpatient stay (weight 1.0), with a geometric mean length of stay of 1.90 days. 124 ICD-10-CM principal diagnoses group into MS-DRGs 064–066 under the CMS definitions manual; the most-searched are listed below.

This DRG is subject to the post-acute care transfer policy: a discharge to a qualifying setting below the mean length of stay is paid per diem rather than in full.
Principal diagnoses that group to MS-DRGs 064–066
From the CMS MS-DRG definitions manual’s principal-diagnosis index: 124 ICD-10-CM codes route here, and the CC/MCC status of the secondary diagnoses decides which of 064–066 the case lands in. The 24 most-searched:
- I63.9Cerebral infarction, unspecified
- I63.81Other cerebral infarction due to occlusion or stenosis of small artery
- I60.9Nontraumatic subarachnoid hemorrhage, unspecified
- I61.9Nontraumatic intracerebral hemorrhage, unspecified
- I63.89Other cerebral infarction
- I62.9Nontraumatic intracranial hemorrhage, unspecified
- I63.511Cerebral infarction due to unspecified occlusion or stenosis of right middle cerebral artery
- I61.0Nontraumatic intracerebral hemorrhage in hemisphere, subcortical
- I62.00Nontraumatic subdural hemorrhage, unspecified

- I63.512Cerebral infarction due to unspecified occlusion or stenosis of left middle cerebral artery
- I61.1Nontraumatic intracerebral hemorrhage in hemisphere, cortical
- I61.5Nontraumatic intracerebral hemorrhage, intraventricular
