About coding membrane brain hemorrhage
The ICD-10-CM code for membrane brain hemorrhage is I60.8 (Other nontraumatic subarachnoid hemorrhage).
Within I60, choose I60.8 (Other nontraumatic subarachnoid hemorrhage) only when documentation doesn't support a more specific option: from carotid siphon and bifurcation (I60.0), from middle cerebral artery (I60.1), from anterior communicating artery (I60.2), from posterior communicating artery (I60.3), from basilar artery (I60.4), from vertebral artery (I60.5), from other intracranial arteries (I60.6), from unspecified intracranial artery (I60.7) and 1 more.
Use an additional code, if known, to indicate National Institutes of Health Stroke Scale (NIHSS) score (R29.7-).
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.
