About coding dementia
The ICD-10-CM code for dementia is F03.90 (Unspecified dementia, unspecified severity, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety). The official index lists 71 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on F03.90.
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.
