ICD-10 Code M02.829 – Other reactive arthropathies, unspecified elbow (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.829 – Other reactive arthropathies, unspecified elbow
What it is
M02.829 identifies a reactive arthropathy affecting the elbow when the elbow side is unspecified. Use it when the chart documents a postinfectious or reactive joint condition, but does not name left or right.
Clinical signs
Typical findings include joint pain, swelling, stiffness, and limited motion in the elbow. Clinical features vary; refer to documentation for evidence of a reactive process and any associated recent infection.
When to use this code
Use this code when the provider documents other reactive arthropathy in the elbow and laterality is not stated. It also fits cases where the elbow is involved, but the record does not support a more specific ICD-10 description.
Check documentation if the note mentions a different joint, a bilateral condition, or a more specific underlying diagnosis. Code the documented site and specificity as written.
Do not use for
Do not use it for rheumatoid arthritis, septic arthritis, gout, or traumatic elbow pain. If the elbow is clearly left or right, use the appropriate laterality-specific code instead.
Coding tip
Verify both the reactive arthropathy diagnosis and the elbow laterality before assigning M02.829.
