I'm not sure which report you're looking at, but "prescription medications to treat complications of diabetes" means things like painkillers for neuropathy, antibiotics for infections, et cetera. Insulin falls under "antidiabetic agents", which treat diabetes itself, not the complications. But most of the 20 million diabetics in the US are type 2 and do not require insulin; it's only Type 1s and the most severe cases Type 2s who take insulin.
