While medical treatment is essential, it can have a negative effect on your credit scores if you’re left with unpaid bills. These types of collection accounts can hurt your credit scores and make it more expensive for you to secure new credit over time. However, medical collections can be inaccurate, and if you believe your medical collections were reported inaccurately to the credit bureaus, you can dispute them with each credit bureau and get them removed or updated based on verification from the collection agency.
