Filing BlueCard® Ancillary Claims

Generally, claims should be filed to the local Blue Cross and Blue Shield Plan. However, there are unique circumstances when claims filing directions will differ based on the type of provider and service.

Ancillary providers are Independent Clinical Laboratory, Durable/Home Medical Equipment and Supplies and Specialty Pharmacy providers. The local Blue Plan as defined for ancillary services is as follows:

Independent Clinical Laboratory (Lab)

  • The Plan in whose state* the specimen was drawn.

Durable/Home Medical Equipment and Supplies (DME)

  • The Plan in whose state* the equipment was shipped to or purchased at a retail store.

Specialty Pharmacy

  • The Plan in whose state* the ordering physician is located.

* If you contract with more than one Plan in a state for the same product type (i.e., PPO or Traditional), you may file the claim with either Plan.

The ancillary claim filing rules apply regardless of the provider's contracting status with the Blue Plan where the claim is filed.

Providers are encouraged to verify member eligibility and benefits by contacting the phone number on the back of the member ID card or call 800-676-BLUE, prior to providing any ancillary service.

Providers that utilize outside vendors to provide services (e.g., sending blood specimen for special analysis that cannot be done by the lab where the specimen was drawn) should utilize in-network participating ancillary providers to reduce the possibility of additional member liability for covered benefits. A list of in-network participating providers may be obtained by using the Provider Finder®.

Members are financially liable for ancillary services not covered under their benefit plan. It is the provider's responsibility to request payment directly from the member for non-covered services.

If you have any questions about where to file your claim, please contact the BCBSTX Provider Customer Service at 800-451-0287.
