ICD-10 Code M02.88 – Other reactive arthropathies, vertebrae (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.88 – Other reactive arthropathies, vertebrae
What it is
This code identifies reactive arthropathy affecting the vertebrae when the specific reactive arthritis type is not otherwise classified. It indicates joint inflammation in the spine linked to a preceding trigger, not a primary spinal infection.
Clinical signs
Typical findings include spinal pain, stiffness, and reduced range of motion. Clinical features vary; refer to documentation, especially for evidence of inflammatory arthritis involving vertebral joints after a triggering infection or other reactive process.
When to use this code
Use M02.88 when the provider documents reactive arthropathy or reactive arthritis involving the vertebrae and does not name a more specific subtype. It is appropriate when the spinal involvement is clearly stated in the diagnosis. If the record only says back pain or arthritis without a reactive cause, check documentation.
Do not use for
Do not use this code for nonspecific dorsalgia, degenerative spine disease, or septic arthritis of the spine. Also avoid it when the provider documents a different inflammatory arthropathy or another site.
Coding tip
Confirm that the chart links the vertebral arthritis to a reactive process; otherwise, you may need a different musculoskeletal code.
