ICD-10 Code M02.122 – Postdysenteric arthropathy, left elbow (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.122 – Postdysenteric arthropathy, left elbow
What it is
M02.122 identifies reactive joint inflammation in the left elbow that occurs after dysentery. Use it when the record links the elbow arthropathy to a 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 postinfectious relationship and laterality.
When to use this code
Use this code when the provider documents postdysenteric arthropathy affecting the left elbow. It is appropriate when the chart clearly connects the joint problem to a previous dysenteric illness. If the laterality or infectious trigger is not documented, check documentation.
Do not use for
Do not use it for unspecified elbow arthropathy or for arthritis without a documented postdysenteric cause. Do not assume laterality or infection history from symptoms alone.
Coding tip
Confirm both the postdysenteric etiology and the left elbow site before assigning M02.122.
