ICD-10 Code M02.111 – Postdysenteric Arthropathy, Right Shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.111 – Postdysenteric arthropathy, right shoulder
What it is
M02.111 identifies reactive arthropathy affecting the right shoulder after dysentery or another intestinal infection. It is used when the shoulder joint inflammation is linked to that preceding infection.
Clinical signs
Expect shoulder pain, stiffness, swelling, and reduced range of motion. Clinical features vary; refer to documentation for the confirmed infectious trigger and joint laterality.
When to use this code
Use M02.111 when the record clearly states postdysenteric arthropathy and specifies the right shoulder. This code fits cases where the provider links the arthropathy to a prior dysenteric illness. If the documentation names a different joint or does not confirm laterality, check documentation.
Do not use for
Do not use this code for nonspecific shoulder pain, septic arthritis, or arthropathy without a documented postdysenteric cause. Do not assign it if the affected side is not the right shoulder.
Coding tip
Code the infectious history and joint laterality exactly as documented, and verify that the provider explicitly connects the arthropathy to dysentery.
