I don't see skyrocketing costs in health care. I see slight variation of cost from just above or below $15B/month over the last 3 days. Overall, your country has more of an income problem. You should start by making sure you can fully staff all your corps and check your worlds market for what you are making to ensure each of your corps can make money each month.
