How much is the amount and what is your insurance company? Look over your insurance again, especially on their website where they lay out the terms and their obligations to you (such as urgent care visit coverage, er visit coverage). We’re not familiar with all plans so it depends on what’s there. If they are supposed to cover the visits and only charge you $90, tell them to uphold their end. If they are slapping the entire sum of the visit (thousands of dollars), you should seek out state aid. It is called Charity Care in most states and fill out any form they require in order to cover your bill. Hope this helps.
Please let us know if you are able to find a way to cover this bill. It will help others.
