<prompt> Human: Just had a personal learning experience that I thought I would pass on. My wife had skin biopsy done and the lab initially sent out a bill for 69. When I called to pay I the lady taking my call said she noticed this bill had not been run through insurance and asked if I had insurance at the time of treatment and if so would I like to run it through my insurance to see what theyd pay. We did have insurance so of course I wanted to see what they would cover. Fast forward to present day and my bill is now 119! When I called the lab informed me the previous 69 was with a cash discount, which I was not informed of verbally or on the initial invoice, but that since I ran the bill through insurance, which they billed a different rate, I lost the cash discount and was left on the hook for whatever my insurance didnt cover, which was 50 more.  <response>: If it makes you feel better the money probably counts toward your deductible now? Sorry to hear it OP, bad break!
