There may be no clear cut answer.
So here’s the situation. I went to get a blood test they said the send me a bill. Over a month passes and no bill. I call them and they say it’s gotten tied up due to insurance issues. I tell them I have no insurance and they agree to send me a bill. At least three weeks have passed since then. What now? Call them again? Ignore the whole thing?
It’s their responsibility to send the bill, yours to pay it. If they don’t send it, it’s their loss.
IANAL. You don’t have to do anything. But eventually that bill will show up, so if you plan to pay eventually it’s to your advantage to know what that amount will be. I don’t know what the law says, but years in business tells me you have no obligation to pay a debt of an unknown amount and the responsibility lies with the service provider to send you a bill. That is reinforced by the fact that you requested a bill and made them aware you haven’t received one and you don’t have insurance. You wouldn’t be expected to send them a blank check, and I don’t think you even have any moral responsibility here either.
When did you get this blood test? Don’t be surprised if months pass before you get that bill, over even more than a year. The medical business is heavily oriented toward payment from insurance companies, private billing goes to the bottom of the pile, but it rarely disappears.
This is how I got a $75 divorce (the initial consulting fee). I called the law office three times after my divorce was final requesting a bill and never received one.
An added bonus was that my ex had sent me the full amount of the divorce lawyer’s fees as part of our agreement. 
Legal advice is best suited to IMHO.

I think you do have to call the medical billing office at least once a month, if only to satisfy yourself that the bill didn’t get lost in the works and next thing you know they send it out to collections.
Depending on just where it might get lost in the system (or even in the U. S. Mail), maybe someone thinks they’ve sent it but you end up not getting it.
I had a few hospital bills from last December. The ambulance co-payment bill took almost a month to reach me, even though I called the ambulance company and they said it had been sent out.
The pharmacy bill took three months to reach me. I called the pharmacy billing office (and it took me multiple calls just to get to them) repeatedly asking where my bill was, just to make sure it hadn’t gotten lost in some shuffle. I didn’t, but it sure took a long time for them to send it out.
You’ve been thoroughly reasonable in reminding them, so you certainly don’t need to do that again.
Just have the money ready just in case they ever get through their inefficiency.
From TriPolar: …private billing goes to the bottom of the pile…"
With the exception of hospitals I disagree. As a private pay individual I typically receive invoices shortly after the service providers monthly billing cycle. And on top of that they usually stipulate payment in full within 30 days. Hospital billing is another story and a reason I try not to go to emergency rooms.
I agree with Senegoid that a few “where’s my bill?” calls spanning a few months are in order. After three tries I would give up. Keep notes of the attempts including who you speak to. If the bill eventually shows up you pay it, minus any late charges with a note explaining why.
I wouldn’t lift a finger to remind them. It is their business and if they don’t ask, you are under no obligation to remind them. I would not, of course, pay any late charges.
I had had delays up to 6 to 9 months on receiving some fairly standard test procedure bills. Apparently medical bills have to go through several levels of approval review and processing before they actually get sent out. It will get to you eventually but it is very unlikely that it’s going to go away. A delay of a few months on receiving a medical procedure bill is almost SOP.
