If you have insurance, any RAW bill from the medical provider should SHOW the insurance reimbursements. And certainly $8000 would more than satisfy most any deductible.
Have you EVER gotten "claims summary" from your insurer?
If NOT issured -- THEY WILL WHEEL/DEAL. Because NOBODY (including the insurance companies) EVER pays the phony ORIGINAL price (the $8000 "rack rate" for example). I sympathize with the private doctors and hospitals because the insurance companies hold all the customer (90%) and therefore can negotiate them into oblivion.
On claims summaries I've seen, when the insurance "pay out" its like 20 to 35% of the phony rack rate. And then my GP charges FOUR OR FIVE TIMES the actual cost. And next year he'll get a letter allowing only 25% -- so he HIKES the rack rate. He MAKES much less than my veterinarian, but a veterinarian HAS to hold their rates down because most customers are UNinsured.
As uninsured or in an "insurance gap" you can negotiate payment plans that add up to maybe 35% of those phony bills.
