[Texas] Medical Collection company hit my credit for a physicians bill for an accident over two years ago, how do I fight back?

I was rear ended over two years ago by an 18!wheeler and taken to the hospital. I provided all of my insurance upon arrival but apparently the physicians side must have not provided my healthcare insurance and now put a derogatory statement on my credit for $1500.

I’m wondering how can I fight this because I provided my insurance information at the time of the accident to the hospital and it looks like my insurance handsomely paid the hospital, but there was a miscommunication by the provider. I’m sure they would have been paid if they filed a claim within the appropriate timing or if the hospital provider them with the insurance.

What steps would I need to take or do to get them to remove this? Thanks in advance.
