ICD-10 Code M02.012 – Arthropathy following intestinal bypass, left shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.012 – Arthropathy following intestinal bypass, left shoulder
What it is
M02.012 identifies arthropathy that develops after intestinal bypass surgery and affects the left shoulder. Use it when the record links the joint problem to the bypass history rather than to trauma or another arthritis type.
Clinical signs
Typical findings include shoulder pain, stiffness, swelling, and reduced range of motion. Clinical features vary; refer to documentation for the side affected and the documented relationship to prior intestinal bypass.
When to use this code
Use M02.012 when the provider documents arthropathy as a consequence of intestinal bypass and specifies the left shoulder. It is appropriate for encounters focused on evaluation, follow-up, or management of this post-surgical joint condition. If the causation or laterality is unclear, check documentation.
Do not use for
Do not use this code for shoulder pain without a documented arthropathy diagnosis or for arthritis unrelated to intestinal bypass. Do not assign it when the record does not specify the left shoulder.
Coding tip
Confirm both the post-bypass cause and left-side laterality in the provider note before assigning M02.012.
