How will I know if a patient is a Medicare Advantage member? 

The ID card issued by Wellmark Blue Cross Blue Shield will include a L5I prefix to the enrollee ID, and include the word 'dental' in the bottom left corner of the ID card.

Special note: When submitting a dental claim, DO NOT include the L5I prefix for the enrollee ID. Use only the identifier that begins with "W" (e.g. W14000209).
