Risk Coding

Risk Coding Tip – Dec 2021

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:
