ICD-10 Code M02.841 – Other reactive arthropathies, right hand (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.841 – Other reactive arthropathies, right hand
What it is
This code identifies a reactive arthropathy affecting the right hand. Use it when the record specifies an inflammatory joint condition in the right hand linked to a reactive process, but not a more specific diagnosis.
Clinical signs
Findings may include joint pain, swelling, stiffness, and reduced range of motion in the right hand. Clinical features vary; refer to documentation for the exact joint involvement and cause.
When to use this code
Use M02.841 when the provider documents other reactive arthropathy in the right hand and no more specific ICD-10-CM code applies. It is appropriate when the right hand is clearly identified as the affected site. Check documentation if the note only says reactive arthritis without laterality or location.
Do not use for
Do not use this code for reactive arthropathy in another site or when the right hand is not documented. Also avoid it if the chart supports a different inflammatory arthritis diagnosis.
Coding tip
Assign laterality only when the provider clearly documents the right hand and the reactive arthropathy diagnosis.
