M01.X1
Direct infection of shoulder joint in infectious and parasitic diseases classified elsewhere
M01.X1 is a non-billable ICD-10-CM code header for direct infection of shoulder joint in infectious and parasitic diseases classified elsewhere. Report a more specific code from it instead. It is part of the FY2027 code set, effective October 1, 2026. The more specific codes under it are M01.X11 Direct infection of right shoulder in infectious and parasitic diseases classified elsewhere, M01.X12 Direct infection of left shoulder in infectious and parasitic diseases classified elsewhere and M01.X19 Direct infection of unspecified shoulder in infectious and parasitic diseases classified elsewhere. Its coding notes include a Code first instruction, 11 Excludes1 entries and 10 Excludes2 entries.

Notes
Also from chapter/block level (4 notes)
- 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.
- Use an external cause code following the code for the musculoskeletal condition, if applicable, to identify the cause of the musculoskeletal condition
