Trick question that can't be answered yes or no. A secondary may or may not cover the Medicare copay/deductible or even coinsurance, so it would depend on what 2ndary you have, regardless if the payment applies to the Medicare copay, then the balance will drop down to the 2ndary and they will coordinate benefits accordingly. EX: Client has Medicare and BCBS-NC SEHP-secondary. They have not met their Medicare copay/deductible. Services billed is 500.00 allowed 400 medicare will deduct 135.00 (copay) and pay 80% of 265.00 $212.00 EOB shows PR= 178.00 This drops to the 2ndary, but they have a 450.00 deductible with their insurance, they haven't met, so they will owe 178.00. If the client had AARP, they would have paid 100% of the deductible and 20% (if they choose that aarp plan). Also if they had met their deductible with SEHP, they would have paid 80% of the 178.00 (minus the copay) and the balance would be the clients. With UHC if the Medicare payment is more than the UHC allowed then no payment is made, so it depends on the various circumstances and what type of plan is secondary
