F01.2 exists in the World Health Organization's base ICD-10 classification, but was never adopted into ICD-10-CM (the United States clinical modification used for medical billing). It cannot be used on a US claim. Reference information from the official WHO classification is shown below.
Code
F01.2
Title
Subcortical vascular dementia
Definition
Includes cases with a history of hypertension and foci of ischaemic destruction in the deep white matter of the cerebral hemispheres. The cerebral cortex is usually preserved and this contrasts with the clinical picture which may closely resemble that of dementia in Alzheimer disease.
