F02.C0Dementia in other diseases classified elsewhere, severe, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety

F02.C0 is the ICD-10-CM diagnosis code for dementia in other diseases classified elsewhere, severe, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety. It belongs to category F02 (dementia in other diseases classified elsewhere), 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 F02.C, choose F02.C0 (without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety) only when documentation doesn't support a more specific option: with behavioral disturbance (F02.C1), with psychotic disturbance (F02.C2), with mood disturbance (F02.C3) and with anxiety (F02.C4).

Code first the underlying physiological condition, such as: Alzheimer's (G30.-), cerebral lipidosis (E75.4), Creutzfeldt-Jakob disease (A81.0-), epilepsy and recurrent seizures (G40.-) and 20 more.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

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.

It is a manifestation code, so it describes the effect of an underlying disease and can't be the principal diagnosis. Code the underlying condition first.

It was added in FY2023, effective October 1, 2022.
