ICD-10 Code M02.06 – Arthropathy following intestinal bypass, knee (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.06 – Arthropathy following intestinal bypass, knee
What it is
This code identifies joint disease in the knee that develops after an intestinal bypass procedure. Use it when the record links the arthropathy to the bypass rather than to trauma, infection, or another arthritis cause.
Clinical signs
Typical findings include knee pain, swelling, stiffness, and reduced range of motion. Clinical features vary; refer to documentation for the confirmed relationship to prior intestinal bypass.
When to use this code
Use M02.06 when the provider documents arthropathy of the knee as a consequence of intestinal bypass surgery. It is appropriate for encounters focused on the joint condition, whether newly recognized or ongoing. Check documentation if the note does not clearly connect the knee problem to the bypass.
Do not use for
Do not use this code for unspecified knee pain, primary osteoarthritis, or inflammatory arthritis without the bypass-related cause. Also avoid it if the intestinal bypass association is not documented.
Coding tip
Link the knee arthropathy to the intestinal bypass in the provider note before assigning M02.06.
