ICD-10 Code M02.19 – Postdysenteric Arthropathy, Multiple Sites (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.19 – Postdysenteric arthropathy, multiple sites
What it is
M02.19 identifies reactive arthritis that occurs after dysentery and affects multiple joints. Use it when the record links the joint problem to a recent intestinal infection.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include joint pain, swelling, and stiffness involving more than one site, with a history of preceding diarrheal illness or dysentery.
When to use this code
Use this code when the provider documents postdysenteric arthropathy and specifies multiple sites. It is appropriate when the arthropathy is described as a postinfectious joint reaction rather than a primary inflammatory arthritis. Check documentation for the causal infection and joint distribution.
Do not use for
Do not use this code if the arthropathy is not linked to dysentery or if the provider documents a different reactive arthritis cause. Check documentation when the site is single-joint or the diagnosis is uncertain.
Coding tip
Code the condition only when the chart clearly connects the arthritis to prior dysentery and identifies multiple sites.
