ICD-10 Code M02.821 – Other reactive arthropathies, right elbow (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.821 – Other reactive arthropathies, right elbow
What it is
M02.821 identifies a reactive arthropathy affecting the right elbow. Use it when documentation specifies an inflammatory joint condition linked to a reactive process and the right elbow is the involved site.
Clinical signs
Typical findings include joint pain, swelling, stiffness, and reduced range of motion in the right elbow. Clinical features vary; refer to documentation for the underlying trigger or associated systemic findings.
When to use this code
Use this code when the provider documents other reactive arthropathy in the right elbow, or a reactive inflammatory arthritis localized to that joint. It is appropriate when laterality is clear and the diagnosis is not better described by a more specific code. Check documentation if the cause or joint site is unclear.
Do not use for
Do not use it for unspecified elbow pain, traumatic injury, or degenerative arthritis without a reactive arthropathy diagnosis. Do not assign it if the record does not confirm the right elbow.
Coding tip
Verify both the reactive arthropathy diagnosis and right-side laterality in the note before coding.
