ICD-10 Code M02.129 – Postdysenteric Arthropathy, Unspecified Elbow (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.129 – Postdysenteric arthropathy, unspecified elbow
What it is
This code identifies reactive joint inflammation in the elbow that follows a dysenteric infection. Use it when the record specifies postdysenteric arthropathy but does not document the affected elbow side.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include elbow pain, swelling, stiffness, and reduced range of motion after a gastrointestinal infection.
When to use this code
Use M02.129 when the provider links elbow arthropathy to a prior dysenteric illness and laterality is not stated. It also fits when the diagnosis is documented as postdysenteric arthropathy of the elbow without further detail.
If the note names the elbow but does not specify right or left, this unspecified code is appropriate. Check documentation if the joint problem is better described as another inflammatory or infectious arthritis.
Do not use for
Do not use this code for elbow pain without a documented postdysenteric cause. Do not use it when laterality is specified and another code is required.
Coding tip
Confirm both the postdysenteric link and the elbow site in the provider note before assigning M02.129.
