  • M00 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
  • The 2023 edition of ICD-10-CM M00 became effective on October 1, 2022.

Type 2 Excludes
Type 2 Excludes Help
A type 2 excludes note represents "not included here". A type 2 excludes note indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When a type 2 excludes note appears under a code it is acceptable to use both the code (M00) and the excluded code together.

    Infectious arthropathies

    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.
