About F01.511
F01.511 is the ICD-10-CM diagnosis code for vascular dementia, unspecified severity, with agitation. It belongs to category F01 (vascular dementia), block F01-F09 (mental disorders due to known physiological conditions) and chapter 5 (mental, Behavioral and Neurodevelopmental disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within F01.51 (vascular dementia, unspecified severity, with behavioral disturbance), F01.511 is specifically for vascular dementia, unspecified severity, with agitation. Related codes cover other behavioral disturbance (F01.518).
Code first: , if applicable, any causal condition.
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 884 (Organic Disturbances and Intellectual Disability, relative weight 1.6001), in MDC 19 (Mental Diseases and Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
The Medicare Code Editor expects this diagnosis only for patients age 15 through 124.
It was added in FY2023, effective October 1, 2022.
