ICD-10 Code M02.84 – Other reactive arthropathies, hand (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.84 – Other reactive arthropathies, hand
What it is
M02.84 identifies a reactive arthropathy affecting the hand. Use it when the record describes joint inflammation in the hand linked to a prior infection or another reactive process.
Clinical signs
Typical findings include painful, swollen, and stiff hand joints. Clinical features vary; refer to documentation for the specific joint involvement and whether the condition is described as reactive arthropathy.
When to use this code
Use this code when the provider documents reactive arthropathy in the hand without a more specific site or subtype. It also fits cases where the hand joints are named as the affected location and the reactive cause is clearly documented.
Do not use for
Do not use it for rheumatoid arthritis, osteoarthritis, gout, or septic arthritis unless the chart specifically says reactive arthropathy. Check documentation if the record only states hand pain or swelling without a confirmed diagnosis.
Coding tip
Confirm both the reactive arthropathy diagnosis and the hand location in the provider note before assigning M02.84.
