M02

Postinfective and reactive arthropathies

Non-billable header

M02 is a non-billable header code. Use one of the more specific codes below.

Inclusion terms

Includes

  • Note: Use an external cause code following the code for the musculoskeletal condition, if applicable, to identify the cause of the musculoskeletal condition
  • Note: This block comprises arthropathies due to microbiological agents. Distinction is made between the following types of etiological relationship:
  • Note: a) direct infection of joint, where organisms invade synovial tissue and microbial antigen is present in the joint;
  • Note: 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.
