Even significant health costs per month are ignored in a corporate environment in the US, though small startups may be different. For entrepreneurs, health care costs would matter before the company was large enough to have figured out benefits.

Any startup employees\founders willing to comment on how health insurance is generally handled at US startups?

I have a chronic health condition that needs some fairly expensive drugs and relatively frequent doctor visits and procedures. My total out of pocket healthcare expenses are less than $500 per year.
