ICD-10 Code M02.10 – Postdysenteric arthropathy, unspecified site (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.10 – Postdysenteric arthropathy, unspecified site
What it is
M02.10 identifies postdysenteric arthropathy affecting an unspecified joint site. Use it when a reactive joint problem follows dysentery, but the affected joint is not documented.
Clinical signs
Typical findings include joint pain, swelling, stiffness, and reduced range of motion after a recent enteric infection. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record links arthritis or arthropathy to prior dysentery and the site is not named. It also fits when the clinician documents postdysenteric arthropathy without specifying a joint. Check documentation if the infection history is unclear.
Do not use for
Do not use it for septic arthritis, traumatic joint pain, or arthropathy with a clearly different infectious cause. Do not assign it if the joint site is documented and another code is more specific.
Coding tip
Confirm both the dysentery history and the unspecified joint site before coding M02.10.
