ICD-10 Code M02.33 – Reiter’s disease, wrist (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.33 – Reiter’s disease, wrist
What it is
M02.33 identifies Reiter’s disease, also called reactive arthritis, affecting the wrist. Use it when documentation specifies this postinfectious inflammatory arthritis in the wrist joint.
Clinical signs
Clinical features vary; refer to documentation. Common findings include joint pain, swelling, and stiffness, with inflammation centered in the wrist and sometimes other joints.
When to use this code
Use this code when the provider documents Reiter’s disease or reactive arthritis involving the wrist. It is appropriate when the diagnosis clearly names the wrist as the affected site. Check documentation if the site is described only generally or if another arthropathy is recorded.
Do not use for
Do not use it for nonspecific wrist pain, traumatic wrist injury, or arthritis without documentation of Reiter’s disease. If the record does not support the wrist site, check documentation.
Coding tip
Verify both the reactive arthritis diagnosis and the anatomic site before assigning M02.33.
