Bull city financial?

Hey guys i’m writing this post because I wanted y’all’s insight on how to approach this. So as I was on my phone I get a Experian notification that my score changed, well my score went down 67 points when I check why is because Bull city financial flagged my account as collections, I call then and they say it’s cause of a medical bill of $188. Question is will paying that off solve this and jump my score but to its original score or will I need a different approach, I wanted to take a home loan but now I can’t because of this. TIA
