The person has Type 1 diabetes treated with insulin but has insulin resistance too. According to a research, Alzheimer's may even be Type 3. A lot of the unexplained features of of Alzheimer's like cell death and tangles in the brain appear to be linked to abnormalities in insulin signaling. This shows that the disease is most probably a neuroendocrine disorder or another type of diabetes.
There is presently no specific code for Type 3. You need to code the diabetes as unspecified with a fifth digit of "0". Moreover, you should add the code V58.67 (Long-term [current] use of insulin) if the patient is expected to be on insulin long-term.
Tip: Make it a point to ask the physician when insulin dependent diabetes" is documented because the term is outdated, and its real meaning is juvenile type diabetes. With such a statement from the physician, you may think about asking whether the diabetes was inducted by another condition or event, like steroid induced diabetes as there's no Type 1 or Type 2 in steroid induced diabetes, now coded with a 249.x (Secondary diabetes mellitus) category code.
