ICD-10 Code M02.12 – Postdysenteric arthropathy, elbow (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.12 – Postdysenteric arthropathy, elbow
What it is
M02.12 identifies reactive joint inflammation affecting the elbow after a dysenteric infection. Use it when the record links the elbow arthritis to a recent or prior gastrointestinal infection.
Clinical signs
Typical findings include elbow pain, swelling, stiffness, and reduced range of motion. Clinical features vary; refer to documentation for the infection history and the affected joint.
When to use this code
Use this code when the provider documents postdysenteric arthropathy specifically in the elbow. It fits cases where the elbow symptoms are described as reactive or postinfectious and the dysenteric trigger is noted. Check documentation if the joint or cause is not clearly stated.
Do not use for
Do not use it for nonspecific elbow pain, septic arthritis, or arthritis without a documented postdysenteric cause. If the diagnosis is only suspected, check documentation.
Coding tip
Confirm both the elbow site and the postdysenteric link in the provider note before assigning M02.12.
