F03 — Unspecified dementia
Is F03 billable?
No — F03 is a non-billable header code. F03 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 24 billable codes beneath F03.
