ICD-10 Code M02.121 – Postdysenteric arthropathy, right elbow (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.121 – Postdysenteric arthropathy, right elbow
What it is
M02.121 identifies postdysenteric arthropathy affecting the right elbow. Use it when joint inflammation is attributed to a prior dysenteric infection and specifically involves the right elbow.
Clinical signs
Clinical features vary; refer to documentation. Typical arthropathy may include elbow pain, swelling, stiffness, and reduced range of motion after a recent or past enteric infection.
When to use this code
Use M02.121 when the record clearly links the right-elbow arthritis to postdysenteric arthropathy. You should also confirm laterality and that the provider documents the dysenteric cause, not another reactive or infectious arthritis.
If the note only says elbow pain or arthritis without the postdysenteric connection, check documentation before coding. This code is for the specific right elbow site, so do not use it for unspecified or other joints.
Do not use for
Do not use this code for nonspecific elbow arthralgia, traumatic elbow injury, or arthritis from another cause. Check documentation if the infection history or laterality is unclear.
Coding tip
Verify both the postdysenteric etiology and the right-sided joint site before assigning M02.121.
