Pathological fracture, humerus

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 3 more specific codes instead:

M84.421 Pathological fracture, right humerus (also a header)
M84.422 Pathological fracture, left humerus (also a header)
M84.429 Pathological fracture, unspecified humerus (also a header)

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 Pathological fracture, humerus
