Doctor’s responsibility to verify insurance before your visit OHIO

Recently we had to switch insurance from my job to my husband’s. The medical insurance company stayed the same just a different guarantor. I went for my annual eye exam and gave them all of the new insurance information. After the visit was done they told me that they don’t accept our vision insurance and I had to pay out of pocket for the visit.

Is it required legally for them to notify me before the visit that they don’t accept my insurance?

Yes I signed the paperwork that says I understood I was financially responsible for the visit. I’m not disputing that I owe the money and have paid them. It feels underhanded to wait til the end to tell me this when they could have notified me before my visit began.
