Arthritis due to other bacteria, knee

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:

  • M00.861 Arthritis due to other bacteria, right knee
  • M00.862 Arthritis due to other bacteria, left knee
  • M00.869 Arthritis due to other bacteria, unspecified knee

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.

Official coding rules

Published by CDC for FY2027. A rule attached to a category binds every code beneath it, so the rules inherited from this code's ancestors are shown with the code they come from.

Inherited from M00 Pyogenic arthritis

Excludes2 - not included here

  • infection and inflammatory reaction due to internal joint prosthesis (T84.5-)

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.

How CDC's index refers to this code

Wording from the official alphabetic index. Much of it appears nowhere in the code description, which is why a search for the everyday phrase so often finds nothing.
