Patient Copayments - Medical
For PPO providers, the plan has a $10 copayment for office visits, $50 for emergency room treatment, and $0 for hospital inpatient admissions. After the claim is adjudicated by the plan, the provider can bill the patient for any remaining allowable balance due to deductibles, copayments, coinsurance, or non-covered expense.

For non-PPO providers, the plan has a $20 copayment for office visits, $50 for emergency room treatment, and $200 for hospital inpatient admissions. Patient billing practice is subject to the provider's policy.
