ICD-10 Code M02.839 – Other reactive arthropathies, unspecified wrist (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.839 – Other reactive arthropathies, unspecified wrist
What it is
This code identifies a reactive arthropathy affecting the wrist when the wrist is not further specified as right or left. It is used for joint inflammation linked to a reactive process, not a primary wrist injury.
Clinical signs
Typical findings include wrist pain, swelling, stiffness, and reduced range of motion. Clinical features vary; refer to documentation for the underlying trigger and whether the wrist involvement is clearly documented.
When to use this code
Use this code when the record documents reactive arthropathy in the wrist but does not specify laterality. It also fits cases where the provider names the condition without identifying a more precise wrist site.
Check documentation if the note only mentions arthritis, joint pain, or another inflammatory arthropathy without confirming a reactive cause. You should not infer the diagnosis from symptoms alone.
Do not use for
Do not use this code for traumatic wrist pain, osteoarthritis, or rheumatoid arthritis. If the wrist side is documented, select the laterality-specific code instead.
Coding tip
Verify both the reactive arthropathy diagnosis and the unspecified wrist documentation before assigning M02.839.
