Other drug-induced secondary parkinsonism

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:

G21.11 Neuroleptic induced parkinsonism
G21.19 Other drug induced secondary parkinsonism

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 Other drug-induced secondary parkinsonism
