Frequently Asked Questions
What is the ICD-10 code for type 2 diabetes?
The code is E11, with subtypes ranging from E11.0 to E11.9 based on specific details.
Can diabetes harm the kidneys?
Yes. High blood sugar can gradually damage kidney filters. Regular kidney testing helps catch problems early.
Will I need insulin if I have type 2 diabetes?
