About F03.90

F03.90 is the ICD-10-CM diagnosis code for unspecified dementia, unspecified severity, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety. It belongs to category F03 (unspecified 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 F03.9, choose F03.90 (without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety) only when documentation doesn't support a more specific option: with behavioral disturbance (F03.91), with psychotic disturbance (F03.92), with mood disturbance (F03.93) and with anxiety (F03.94).

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), DRG 974 (HIV with Major Related Condition with MCC, relative weight 3.0506), DRG 975 (HIV with Major Related Condition with CC, relative weight 1.3252) and DRG 976 (HIV with Major Related Condition without CC/MCC, relative weight 0.8124), in MDC 19 (Mental Diseases and Disorders) and MDC 25 (Human Immunodeficiency Virus Infections), 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 has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2023 (title revised).

Before ICD-10, this condition was coded in ICD-9-CM as 290.0 (senile dementia, uncomplicated), 290.10 (Presenile dementia, uncomplicated), 290.11 (Presenile dementia with delirium) and 5 more.
