Phakomatoses, not elsewhere classified

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 4 more specific codes instead:

Q85.0 Neurofibromatosis (nonmalignant) (also a header)
Q85.1 Tuberous sclerosis
Q85.8 Other phakomatoses, not elsewhere classified (also a header)
Q85.9 Phakomatosis, unspecified

What has happened to this code

Every change the publisher made, from 2012 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.

FY2012 Added to the draft code set draft Phakomatoses, not elsewhere classified
