Through our membership in the National Community Pharmacists Association (NCPA), The Senior Care Pharmacy Coalition (SCPC), the National Association of Chain Drug Stores (NACDS) and the Patient Access to Pharmacists’ Care Coalition (PAPCC), AmerisourceBergen collaborates with the pharmacy community on many key legislative and regulatory issues. Supporting state and federal initiatives to ensure fair reimbursement is a priority. MAC lists differ from one payer to another, as there is no standardization in developing these lists. Updates to MAC lists do not always occur on a regular basis. These factors put a strain on pharmacy, which in turn can put patient access at serious risk.
