Other specified disorders of bone density and structure, upper arm

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:

M85.821 Other specified disorders of bone density and structure, right upper arm
M85.822 Other specified disorders of bone density and structure, left upper arm
M85.829 Other specified disorders of bone density and structure, unspecified upper arm

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.
