ICD-10 Code M02.351 – Reiter’s disease, right hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.351 – Reiter’s disease, right hip
What it is
M02.351 identifies Reiter’s disease, also called reactive arthritis, affecting the right hip. It is a post-infectious inflammatory joint condition coded by site and laterality.
Clinical signs
Typical findings include joint pain, swelling, and stiffness, often with asymmetric lower-extremity involvement. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents Reiter’s disease or reactive arthritis specifically in the right hip. It may appear in assessments, problem lists, or encounter diagnoses tied to that joint.
Choose the code only when laterality is clear and the right hip is the documented site. Check documentation if the record says multiple joints, unspecified hip, or a different inflammatory arthritis.
Do not use for
Do not use M02.351 for left hip, bilateral hip, or unspecified hip disease. Do not use it when the diagnosis is another arthropathy or when Reiter’s disease is not documented.
Coding tip
Verify both the condition name and the right-sided hip location before assigning this code.
