Guardian's claim submission address changing

October 04, 2018 Guardian's group dental preferred provider organization (PPO) and dental health maintenance organization (DHMO) claim submission P.O. boxes in Spokane, Washington, will officially close on Oct. 31.   

The new claim submission address for PPO claims is P.O. Box 981572, El Paso, TX, 79998-1572.

The new claim submission address for DHMO claims is: P.O. Box 981571, El Paso, TX 79998-1571.

Submissions to the Spokane address after Oct. 31 will be returned to sender.

"We have changed our mailing address for paper claims and want to make sure that the membership is aware of this, so that there are no unnecessary delays for claims processing," said Dr. Randi Tillman, chief dental officer of Guardian.

The claim submission addresses for the PPO and DHMO dental claims changed in November 2017 as part of the transition to their new imaging and support vendor SwissPost Solutions.  

Since that time, all explanations of benefits have included the new El Paso P.O. Box as the return address.  

Through January, messaging was also included on all DHMO and PPO provider explanations of benefits explaining this change and providing the new P.O. boxes in El Paso.
