Are we required to file secondary insurance claims if we participate with both the primary and secondary insurers? We'd like to just file primary and then bill the patient and let the patient file the secondary. We would continue to file Medicare secondaries.

More and more practices are refusing to file secondaries. It's a growing trend. The only reason you'd have to send the secondaries is if your contract with the payer dictates it. Otherwise, you simply are providing a service to patients. Check your contracts, and if for some reason it does require you to do it, negotiate out of it.
