ICD-10 code for cerebral vasospasm

The ICD-10-CM code for cerebral vasospasm is I67.848 (Other cerebrovascular vasospasm and vasoconstriction). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on I67.848.

Within I67.84, choose I67.848 (Other cerebrovascular vasospasm and vasoconstriction) only when documentation doesn't support a more specific option: reversible cerebrovascular vasoconstriction syndrome (I67.841).

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.

In MS-DRG v44.0, it is part of the grouping logic for DRG 061 (Ischemic Stroke, Precerebral Occlusion or Transient Ischemia with Thrombolytic Agent with MCC, relative weight 2.7211), DRG 062 (Ischemic Stroke, Precerebral Occlusion or Transient Ischemia with Thrombolytic Agent with CC, relative weight 1.7781), DRG 063 (Ischemic Stroke, Precerebral Occlusion or Transient Ischemia with Thrombolytic Agent without CC/MCC, relative weight 1.455) and DRG 069 (Transient Ischemia without Thrombolytic, relative weight 0.7964), in MDC 01 (Diseases and Disorders of the Nervous System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
