Onboarding

Updated 11/15/2024. For the most up-to-date information on how to request a P Number, please visit the CMS Discarded Drugs page.

CMS uses P Numbers to identify manufacturer accounts in the Health Plan Management System (HPMS) for various programs such as the Coverage Gap Discount Program (CGDP) and the Discarded Drug Program. If you are new to the Discarded Drug Program, and have not been issued a P Number, please submit the following information via email to DiscardedDrugs@cms.hhs.gov to request a P Number:

• Manufacturer Legal Name
• Data Universal Numbering System (DUNS) Number
• Employer Identification Number (EIN)
• Primary Contact First and Last Name
• Primary Contact Email Address
• Primary Contact Phone Number
• Subject Line of the Email Should Read “[Manufacturer Name] Request for P Number”

After you send your request, CMS will contact you should they require any additional information to issue a P Number. Once your P Number is issued, a representative from the TPA Support Center will reach out to begin the HPMS onboarding process.
