ICD-10 code for Binswanger's leukoencephalopathy

The ICD-10-CM code for Binswanger's leukoencephalopathy is I67.3 (Progressive vascular leukoencephalopathy).

Within I67 (other cerebrovascular diseases), I67.3 is specifically for progressive vascular leukoencephalopathy. Related codes cover dissection of cerebral arteries, nonruptured (I67.0), cerebral aneurysm, nonruptured (I67.1), cerebral atherosclerosis (I67.2), hypertensive encephalopathy (I67.4), Moyamoya disease (I67.5), nonpyogenic thrombosis of intracranial venous system (I67.6), cerebral arteritis, not elsewhere classified (I67.7), other specified cerebrovascular diseases (I67.8) and 1 more.

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 056 (Degenerative Nervous System Disorders with MCC, relative weight 2.2655), DRG 057 (Degenerative Nervous System Disorders without MCC, relative weight 1.2838), DRG 974 (HIV with Major Related Condition with MCC, relative weight 3.0506), DRG 975 (HIV with Major Related Condition with CC, relative weight 1.3252) and DRG 976 (HIV with Major Related Condition without CC/MCC, relative weight 0.8124), in MDC 01 (Diseases and Disorders of the Nervous System) and MDC 25 (Human Immunodeficiency Virus Infections), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
