New MSN Message to Be Included on All Vendor Claims
On all vendor claims, whether paid or denied, the designated A/B MACs (B) shall
include the following new Medicare Summary Notice Message:
Your physician participates in the Competitive Acquisition Program for Medicare Part B
drugs (CAP). The drug(s) you received in your physician's office were provided by an
approved CAP vendor. You will receive two separate Medicare Summary Notices
(MSNs). This MSN is from the Medicare A/B MAC (B) that processes claims for your
drug that came from the approved CAP vendor. You will receive another MSN from the
A/B MAC (B) that processes claims for your physician, for the administration of the
drug(s). If you appeal the determination for this drug vendor claim, you must send your
appeal to the A/B MAC (B) address listed on the physician administration MSN, and not
this vendor claim MSN.
Spanish:
Su médico participa en el Programa de Adquisición Competitiva para las medicinas
cubiertas por la Parte B de Medicare (CAP, por sus siglas en inglés). Las medicinas que
usted recibió en la oficina de su médico fueron provistas por un suplidor autorizado del
CAP. Usted recibirá dos Resúmenes de Medicare por separado. Este Resumen es de la
empresa de seguros Medicare que procesa las reclamaciones de sus medicinas provistas
por el suplidor autorizado del CAP. Usted recibirá otro Resumen de la empresa de
seguros Medicare que procesa las reclamaciones de su médico, por el suministro de sus
medicinas. Si usted apela la decisión de esta reclamación del suplidor de medicinas, debe
enviar la apelación a la empresa de seguros Medicare que se menciona en el Resumen de
la reclamación de su médico y no a la dirección que aparece en este Resumen.
