What You Need to Know about Compendia

A positive or a negative listing in one or more of the Medicare-approved drug compendia can have a significant impact on whether a pharmaceutical product is covered, ultimately affecting prescribing decisions and patient access.

As such, Xcenda recommends 5 key tasks to help manufacturers consider the impact of the compendia on their pipeline and current brands.

  • Understand the history, application, and processes involved with the drug compendia
  • Examine compendia listings for indications in development, which can assist in determining the most beneficial Phase 2 studies to initiate
  • Conduct a compendia analysis upon publication of Phase 2 and 3 studies to determine if and to which compendia the data should be submitted for review
  • Monitor compendia for new, updated, and changed listings for your products and others within relevant disease states
  • Compare the compendia listings to what payers are covering

Since Medicare coverage for off-label drug use was first provided through legislation in 1993, the reimbursement landscape has changed, causing numerous governmental agencies and other key stakeholders to review Medicare policies regarding off-label coverage for drugs and biologics. Not surprisingly, coverage changes for off-label use continues to be of great interest to many stakeholders, including physicians, patients, and payers.
