ICD-10 Code E10.618 – Type 1 diabetes mellitus with other diabetic arthropathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E10.618 – Type 1 diabetes mellitus with other diabetic arthropathy
What it is
This code identifies type 1 diabetes mellitus with a diabetic joint disorder that is not one of the more specific arthropathies. Use it when the record links the arthropathy directly to diabetes.
Clinical signs
Clinical features vary; refer to documentation. You may see joint pain, stiffness, swelling, reduced range of motion, or degenerative changes described as diabetic arthropathy.
When to use this code
Use E10.618 when the provider documents type 1 diabetes and specifically identifies another diabetic arthropathy. It applies when the joint condition is attributed to diabetes, not to trauma, infection, or another rheumatologic disease. Check documentation if the arthropathy type is unclear.
Do not use for
Do not use this code for type 2 diabetes or for diabetic arthropathy that is not documented as linked to type 1 diabetes. Do not assign it for nonspecific joint pain without a documented diabetic cause.
Coding tip
Code the diabetes and the arthropathy exactly as documented, and verify that the provider connects the joint disorder to type 1 diabetes.
