• ICD-10 Diagnosis Code for 250.03 Type 1 Diabetes Mellitus, Juvenile, Uncontrolled?

    Question: What would be the appropriate ICD-10 code for 250.03 Type 1 Diabetes mellitus, juvenile, uncontrolled?

    Answer: Z03.89 Encounter for observation for other suspected diseases and conditions ruled out is appropriate until a better option is found or we are told by a carrier to do otherwise. E10.65 is inappropriate as the ophthalmologist may not know if the patient is hyperglycemic or hypoglycemic until tested.
