Modifiers
The following subclassification to indicate the site of involvement is provided for optional use with appropriate categories in Chapter XIII. As local extensions or specialty adaptations may vary in the number of characters used, it is suggested that the supplementary site subclassification be placed in an identifiably separate position (e.g. in an additional box). Different sub-classifications for use with derangement of knee, dorsopathies, and biomechanical lesions not elsewhere classified are given at M23, before M40 and at M99 respectively.

BlockM00-M25ArthropathiesOpen
Inclusions
- Disorders affecting predominantly peripheral (limb) joints
BlockM00-M03Infectious arthropathiesOpen
Note
This block comprises arthropathies due to microbiological agents.
Distinction is made between the following types of etiological relationship:
-
direct infection of joint, where organisms invade synovial tissue and microbial antigen is present in the joint;
-
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.
