6D80.2 Alzheimer disease dementia, mixed type, with cerebrovascular disease International Classification of Diseases for Mortality and Morbidity Statistics, 11th Revision, v2024-01 Dementia due to Alzheimer disease and concomitant cerebrovascular disease.
coding note This category should never be used in primary tabulation. The codes are provided for use as supplementary or additional codes when it is desired to identify the presence of dementia in diseases classified elsewhere.
When dementia is due to multiple aetiologies, code all that apply.
postcoordination Add Stem and/or Extension codes to form a cluster code which adds detail to the condition.
