Infectious arthropathies (M00-M02) ICD-10-CM
The M00–M02 section covers infectious arthropathies with 325 ICD-10-CM diagnosis codes, of which 242 are billable in fiscal year 2027. The section is organized into the 3 code ranges listed below.
- 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.
