ICD-10 Code M02.851 – Other reactive arthropathies, right hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.851 – Other reactive arthropathies, right hip
What it is
M02.851 identifies a reactive arthropathy affecting the right hip. Use it when the record shows a joint inflammation that follows an infection or another reactive process, and the right hip is specifically documented.
Clinical signs
Typical findings include hip pain, stiffness, reduced range of motion, and tenderness. Clinical features vary; refer to documentation for the underlying trigger and whether the right hip is the confirmed site.
When to use this code
Use this code when the provider documents reactive arthropathy or a similar postinfectious inflammatory joint condition in the right hip. It is appropriate when the diagnosis is established in the chart, not merely suspected. Check documentation if the note names another joint or does not specify laterality.
Do not use for
Do not use it for nonspecific hip pain, osteoarthritis, or septic arthritis. If the record does not support a reactive arthropathy diagnosis, check documentation.
Coding tip
Confirm both the reactive arthropathy diagnosis and right-side laterality before assigning M02.851.
