The change to the Anthem network does not affect your PPO plan benefits, including your deductible, copays and coinsurance. The amount you paid toward your deductible and out-of-pocket maximum was carried over when the change to the Anthem network took place.
However, your deductible, copays and coinsurance will increase to out-of-network amounts if your provider is not in the Anthem PPO network. See: Is Your Provider in the Anthem Network? to check.
