When billing for local and out-of-area claims, please remember to include both the alpha prefix and complete member ID number as it appears on the member?s ID card. AmeriHealth rejects claims not billed with the complete member ID number and date of birth. For timely and accurate claim payment, the full member ID must be billed as it appears on the member ID card. Also, be sure that you are using the most recent ID card for the member, as the number may change during our transition to a new operating platform.
