That number seemed too large to be true, and I think you might be conflating some numbers...

The NIH study about Economic Costs of Diabetes in the US in 2022 [1] states:

>For cost categories analyzed, care for people diagnosed with diabetes accounts for 1 in 4 health care dollars in the U.S., 61% of which are attributable to diabetes.

So, 25% of health care (not hospital) dollars in the US are apportioned to people with diabetes, and in 61% of those cases, the cause is directly attributable to diabetes itself.

Similarly, an NHS study [2] revealed that 60% of overall diabetes spend goes towards diabetes-related complications.

Finally, this presentation [3] states that: "hospital stays involving patients with diabetes contributed almost $83 billion or 23% of the total hospitalization costs in the United States," and, of course, not all of those were directly diabetes-related.

Obviously that is still a staggering amount of money spent on diabetes every year, and represents a huge burden on our healthcare system. But 60% for all hospital expenditure just doesn't track from my cursory Google-ing here.
