Welcome to mamapedia!!!
Yes, it's allowed. Doctors offices DO NOT have to accept new patients. It's that simple.
Just because they are registered does NOT mean they HAVE to accept the insurance. Nor does it mean that the insurance records are up-to-date.
They told you upfront they are NOT accepting new patients! You should be thankful they told you that. Do you want to go in and sit for hours waiting? That's what happens in doctor's offices when they are over-burdened with patients.
If they took you in as a patient? then yes, they have to honor the contract, to the best of my knowledge. But I would assume since they told you they were not accepting new patients....you didn't go in to the office????
