Based on the given information, the amount that will be billed to MyLife, the patient's secondary insurance, is $103.
The secondary insurance refers to the second insurance plan that an individual is covered under.
While the first is recognized as the primary insurance, the secondary insurance bears liability for the remaining insurable interest.
The percentage of the medical expenses paid by the PPO = 70%
The office visit copayment = $20
The total medical bill of the patient = $410
The amount paid by the PPO = $287 ($410 x 70%)
The amount that will be billed to MyLife Insurance = $103 ($410 - $287 - $20)
Thus, the amount billed to the MyLife Insurance is $103.
