Sending claims to secondary if there is no CCD left for secondary to pay

I recently read something in one of the payer manuals that said they still want claims sent to them if they are the secondary payer even if we know they would not pay because there was no CCD left from primary payer. What is your billing practice? If there is no CCD or PR left from how the primary payer processed and paid do you still submit claims to the secondary (whether its commercial or MA)?
