I60.7Nontraumatic subarachnoid hemorrhage from unspecified intracranial artery

I60.7 is the ICD-10-CM diagnosis code for nontraumatic subarachnoid hemorrhage from unspecified intracranial artery. It belongs to category I60 (nontraumatic subarachnoid hemorrhage), block I60-I69 (cerebrovascular diseases) and chapter 9 (diseases of the circulatory system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within I60, choose I60.7 (from unspecified intracranial artery) 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), other nontraumatic subarachnoid hemorrhage (I60.8) and 1 more.

Don't report I60.7 together with the conditions in its Excludes1 note: berry aneurysm, nonruptured (I67.1).

Use an additional code, if known, to indicate National Institutes of Health Stroke Scale (NIHSS) score (R29.7-).

As a secondary diagnosis it is 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.

In MS-DRG v44.0, it is part of the grouping logic for DRG 020 (Intracranial Vascular Procedures with Principal Diagnosis Hemorrhage with MCC, relative weight 7.9629), DRG 021 (Intracranial Vascular Procedures with Principal Diagnosis Hemorrhage with CC, relative weight 5.4726), DRG 022 (Intracranial Vascular Procedures with Principal Diagnosis Hemorrhage without CC/MCC, relative weight 3.3534), DRG 023 (Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis with MCC or Antineoplastic Implant or Epilepsy with Neurostimulator, relative weight 5.7444), DRG 024 (Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis without MCC, relative weight 3.9708), DRG 064 (Intracranial Hemorrhage or Cerebral Infarction with MCC, relative weight 1.9712) and 4 more, in MDC 01 (Diseases and Disorders of the Nervous System) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 430 (subarachnoid hemorrhage).
