Our providers very often document causal relationships between dementia and conditions such as:
Depression
Anxiety
Psychosis
Delusions
Hallucinations
Therefore I am seeking clarity how to properly code:
Dementia with Depression
Is it F03.90 and F32.9 or just F03.90?

Dementia with Anxiety
Is it F03.90 and F41.9 or just F03.90?

Dementia with Psychosis
Is it F03.90 and F29 or just F03.90

Any clarification on this would be most helpful.
Thank you.
