About coding intracranial nontraumatic hemorrhage
The ICD-10-CM code for intracranial nontraumatic hemorrhage is I62.9 (Nontraumatic intracranial hemorrhage, unspecified). The official index lists 45 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on I62.9.
Within I62, choose I62.9 (intracranial hemorrhage, unspecified) only when documentation doesn't support a more specific option: subdural hemorrhage (I62.0) and extradural hemorrhage (I62.1).
Use an additional code, if known, to indicate National Institutes of Health Stroke Scale (NIHSS) score (R29.7-).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
