About coding Apoplectiform convulsions
The ICD-10-CM code for Apoplectiform convulsions is I67.82 (Cerebral ischemia).
Within I67.8 (other specified cerebrovascular diseases), I67.82 is specifically for cerebral ischemia. Related codes cover acute cerebrovascular insufficiency (I67.81), posterior reversible encephalopathy syndrome (I67.83), cerebral vasospasm and vasoconstriction (I67.84), hereditary cerebrovascular diseases (I67.85) and other cerebrovascular disease (I67.89).
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.
