Help please !!!

Hey ladies... so last year after I had my baby I had to see a nurse practitioner instead of my usual doctor for my 6 week appointment. Well I had to get lab work done and come to find out someone in the office sent it to a lab that my insurance didn’t take instead of my usual lab !

As soon as I received the bill in the mail I was intending on calling. Then all hell broke loose in my family, I started going through PPD, my hubby and I separated for 3 months (my choice), I had 2 family deaths back to back from covid, and I forgot about it completely! Today I logged on to trans union and it’s on my credit report! Is there anything I can do ? It’s not my fault they sent my labs to the wrong place, but I should have disputed it with the office as soon as I got the bill 😔

Is there anything I can do now ?
