Is it possible the Doctor's office sent the bill to your old address in Texas and it wasn't forwarded?
The Doctor's office may not have received a final determination from your insurance company until well after you moved. Sometimes it take 90 days or more from the time the insurance company received the claim. When they did not get a reply or payment, they may have felt they had no choice but forwarding you account to collections.
Try contacting the Doctor's office first. Explain the circumstances and offer to remit payment immediately. Depending upon the agreement they have with the collection agency, they may be able to take care of it. Be aware that it may now be out of their hands and you'll have to deal directly with the collection agency. Make sure you receive a receipt for the payment.
Hope this information helps. Good luck.
