ICD-10 Code M02.11 – Postdysenteric arthropathy, shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.11 – Postdysenteric arthropathy, shoulder
What it is
M02.11 identifies reactive joint inflammation affecting the shoulder after dysentery or a related intestinal infection. Use it when the record links shoulder arthropathy to a prior postinfectious process.
Clinical signs
Typical findings include shoulder pain, stiffness, swelling, and reduced range of motion. Clinical features vary; refer to documentation for the infectious trigger and whether the arthropathy is active or historical.
When to use this code
Use this code when the provider documents postdysenteric arthropathy specifically in the shoulder. It is appropriate when the shoulder joint problem is described as a sequela or reactive condition after dysentery or a similar enteric infection.
If the note only states shoulder pain, arthritis, or postinfectious arthropathy without the dysenteric link, check documentation before assigning M02.11. Code the documented laterality or joint site only as recorded.
Do not use for
Do not use M02.11 for uncomplicated shoulder pain, degenerative arthritis, septic arthritis, or reactive arthropathy without a documented postdysenteric cause. Check documentation if the infectious history is unclear.
Coding tip
Confirm both the shoulder site and the dysenteric/postinfectious etiology in the provider note before coding M02.11.
