Frontotemporal dementia

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 2 more specific codes instead:

G31.01 Pick's disease
G31.09 Other frontotemporal neurocognitive disorder

What has happened to this code

FY2012 Added to the draft code set draft Frontotemporal dementia
