Pathological fracture in neoplastic disease, unspecified ulna and radius

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 6 more specific codes instead:

M84.539A Pathological fracture in neoplastic disease, unspecified ulna and radius, initial encounter for fracture
M84.539D Pathological fracture in neoplastic disease, unspecified ulna and radius, subsequent encounter for fracture with routine healing
M84.539G Pathological fracture in neoplastic disease, unspecified ulna and radius, subsequent encounter for fracture with delayed healing
M84.539K Pathological fracture in neoplastic disease, unspecified ulna and radius, subsequent encounter for fracture with nonunion
M84.539P Pathological fracture in neoplastic disease, unspecified ulna and radius, subsequent encounter for fracture with malunion
M84.539S Pathological fracture in neoplastic disease, unspecified ulna and radius, sequela

What has happened to this code

Every change the publisher made, from 2014 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.

How CDC's index refers to this code
