Worst Mistake - Rude Staff and Billing Problems

Scheduled a physical which should have been covered at 100%. They decided to bill it as routine vs. preventive and then had the nerve to send me a bill for over $500!!! If they billed it the right way in the first place it would have been paid by the insurance company immediately vs. having to wait 8+ months to get paid. Their staff is incredibly rude. I would NOT, NOT, NOT recommend this practice to anyone!
