ICD-10 code for senile paranoia

The ICD-10-CM code for senile paranoia is F03 (Unspecified dementia).

To report this condition, pick the subcode that matches the documentation: F03.9 (unspecified severity), F03.A (mild), F03.B (moderate) and F03.C (severe).

The conditions in its Excludes2 note aren't part of F03, but may be coded alongside it if the patient has both: dementia with delirium or acute confusional state (F05) and mild memory disturbance due to known physiological condition (F06.8).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
