Question: Which ICD-10-CM code should I report for vascular dementia without behavioral disturbance? Ohio Subscriber Answer: You should report code F01.50 (Vascular dementia without behavioral disturbance) for vascular dementia without behavioral disturbance. Don’t forget: When reporting a code from category F01.5- (Vascular dementia), you should code first the underlying physiological condition or sequelae of cerebrovascular disease, per the ICD-10-CM manual. For example, if the patient has vascular dementia without behavioral disturbance associated with cerebral atherosclerosis, you should report I67.2 (Cerebral atherosclerosis), F01.50 on your claim.
