Wiki Patients with 2 commercial insurances

They are both going to have their own allowed amount, so I accept whichever is higher. You are allowed to collect your entire contracted amount from an insurance company.

Say you participate with both carriers and you have a $300 charge. Insurance 1 allows $150 and they pay $150 but Insurance carrier 2 allows $200. I would not write off anything after Insurance 1's payment and bill Insurance carrier 2 fo the balance. Insurance 2 should pay the balance up to their allowed amount of $200 (an additional $50). I will then accept their contract amount as payment in full and adjust off the remaining $100.
