ICD-10 Code E11.618 – Type 2 diabetes mellitus with other diabetic arthropathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E11.618 – Type 2 diabetes mellitus with other diabetic arthropathy
What it is
This code identifies type 2 diabetes with a joint disorder attributed to diabetes, but not specifically diabetic osteoarthropathy or another more precise arthropathy code. Use it when the record links the arthropathy to diabetes.
Clinical signs
Clinical features vary; refer to documentation. You may see chronic joint pain, stiffness, swelling, reduced range of motion, or deformity when the clinician describes diabetic arthropathy.
When to use this code
Use E11.618 when the provider documents type 2 diabetes and specifically identifies another diabetic arthropathy. The note should connect the joint condition to diabetes, not just mention both problems separately. Check documentation if the arthropathy type is unclear.
Do not use for
Do not use this code for diabetic neuropathy, osteoarthritis without a diabetic link, or unspecified joint pain. If the chart does not clearly state diabetic arthropathy, code the documented condition instead.
Coding tip
Assign this code only when the provider explicitly ties the arthropathy to diabetes; otherwise, query or code the documented joint diagnosis.
