ICD-10 Code M02.332 – Reiter’s disease, left wrist (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.332 – Reiter’s disease, left wrist
What it is
M02.332 identifies Reiter’s disease, also called reactive arthritis, affecting the left wrist. Use it when the record specifically documents this postinfectious inflammatory arthritis in that joint.
Clinical signs
Typical findings include joint pain, swelling, and stiffness, often with an asymmetric pattern. Clinical features vary; refer to documentation for the wrist involvement and any supporting diagnosis of reactive arthritis.
When to use this code
Use this code when the provider documents Reiter’s disease or reactive arthritis in the left wrist. It fits cases where the left wrist is the stated site and the diagnosis is confirmed in the medical record. Check documentation if laterality or the exact arthritis type is unclear.
Do not use for
Do not use it for nonspecific wrist pain, swelling, or arthritis without a documented diagnosis of Reiter’s disease. Do not assign it if the condition is in another joint or the side is not confirmed.
Coding tip
Verify both the diagnosis name and left-side laterality in the note before coding.
