Type 2 Diabetes Mellitus with Complications
When coding for patients with diabetes, it is very important to use codes that account for the whole clinical picture—especially the complications associated with diabetes. Start with E11, the code for diabetes, and use the digits following the decimal point to increase your specificity:
| Fourth Digit | Body Region | Example of ICD 10 |
Description | RAF | Additional Information |
| 2 | Kidney complications | E11.22 | Type 2 diabetes with chronic kidney disease | 0.302 | Still need to code the kidney stage, e.g., N18.31 |
| 3 | Vision complications | E11.311 | Type 2 diabetes with diabetic retinopathy and macular edema | 0.302 | |
| 4 | Neurological complications | E11.42 | Type 2 diabetes with polyneuropathy | 0.302 | |
| 5 | Circulatory complications | E11.51 | Type 2 diabetes with peripheral vascular complications | 0.302 | |
| 6 | Other specified complications | E11.65 | Type 2 diabetes with hyperglycemia | 0.302 | Recommended to use when your patient has “uncontrolled” Type 2 diabetes. |
| 9 | Unspecified | E11.9 | Type 2 diabetes, with no complication | 0.105 |
