M01

Direct infections of joint in infectious and parasitic diseases classified elsewhere

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 1 more specific code instead:

  • M01.X Direct infection of joint in infectious and parasitic diseases classified elsewhere (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.

  1. FY2012 Added to the draft code set draft Direct infections of joint in infectious and parasitic diseases classified elsewhere

Official coding rules

Inherited from the M00-M02 section Infectious arthropathies (M00-M02)

Note

  • This block comprises arthropathies due to microbiological agents. Distinction is made between the following types of etiological relationship:
  • a) direct infection of joint, where organisms invade synovial tissue and microbial antigen is present in the joint;
  • b) indirect infection, which may be of two types: a reactive arthropathy, where microbial infection of the body is established but neither organisms nor antigens can be identified in the joint, and a postinfective arthropathy, where microbial antigen is present but recovery of an organism is inconstant and evidence of local multiplication is lacking.
