Dealing with first Hospital Bill, how should I handle this?

I didn’t really know what to put for the flair, so I apologize.

Alright, so I went to the ER in an ambulance because I tried a THC edible for the first time (like 50mg, and I’ve never done ANYTHING before). I had a really bad panic attack and thought I took fentanyl (my brain convinced me the edible was laced). Ended up at the hospital, they gave me a pill and I ran some blood test. Went home in an Uber. I’m in the state of Florida btw.

I KNOW, I’m a very big idiot, I still cannot believe myself for how ridiculously I acted.

Now I have three different medical bills. I just wanna understand how to deal with the hospital bill first. It’s about $590. For context, I’m 19 and I do have insurance, but I was part of pediatric insurance and so I got taken out of it automatically a little after I turned 19. I have to call up insurance company to find out whether I was under the plan during the incident. I’m re-enrolled as of now.

So for the actual hospital bill, I went to a non-profit county hospital. Here are the steps I will take to hopefully reduce or waive this bill.

Call and give insurance information (I have a feeling insurance won’t cover since (I think) I wasn’t enrolled in the plan at the time of incident)

If step 1 doesn’t solve this bill issue, then I will do these:

2. Call hospital and ask for charity care / financial assistance eligibility, and how to apply.
3. Ask for an itemized bill, critique and remove unfair / unnecessary charges
4. Negotiate bill, ask about settlement amount, try to get bill reduced by 50%. Call multiple times if needed.

Of course I won’t have to do these three if step 1 works and insurance takes care of the bill for the most part.

What do you guys think about my plan to deal with this bill? Is there anything else I should do? Is there any more information you need? I can provide it. I’m stressed because I don’t wanna have to spend so much money on this stupid bill, which shouldn’t even be this expensive because they barely did anything at the hospital.

Finally, the ER trip happened in mid-June and I got my first bill in July. So I have ample time to deal with all of this, right?

Thanks in advance to those who help, and I wish the best for you.
