When validating purchases and submitted claims, Account Identifier Mappings helps 340B ESP associate purchases and submitted claims with the correct account based on pharmacy and identifier relationships. These mappings determine which purchases and claims are evaluated together for purchase validation.
To access Account Identifier Mappings, select Manage Identifiers from the Unassigned Identifiers for Review tile in Purchase Validation to review, assign, and transfer identifiers.
What are identifiers?
In Account Identifier Mappings, identifiers are values, such as HIN, DEA, and NPI, that help identify 340B pharmacies or dispensing locations.
These identifiers are mapped to contract pharmacy locations and CE Pharmacies and Clinics, which subsequently link purchases and claims to identifiers assigned to their respective pharmacies. Mapping identifiers helps ensure purchases and submitted claims are accurately associated to the appropriate account.
What are pharmacy groups?
A pharmacy group represents a set of related pharmacies that are part of the same chain or pharmacy network. In 340B ESP, the Pharmacy Groups section shows the pharmacy groups associated with the selected covered entity.
Each pharmacy group card summarizes the number of pharmacies in the group and the types of identifiers associated with those pharmacies, such as DEA, HIN, or NPI identifiers.
Pharmacy groups include all active 340B contract pharmacies or CE Pharmacies and Clinics listed under your covered entities' HRSA arrangements. The Unassigned pharmacy group consists of identifiers that 340B ESP is unable to associate with a single dispensing location, requiring the covered entity to assign it to a single location.
Contract Pharmacy Group
Active contract pharmacies from HRSA may be displayed individually or grouped together when they are part of the same chain. Chain pharmacies appear as an aggregated pharmacy group, while non-chain contract pharmacies are listed individually.
CE Pharmacies and Clinics Pharmacy Group
Entity-owned pharmacies and facilities from HRSA are grouped together under CE Pharmacies and Clinics. This grouping helps distinguish CE Pharmacies and Clinics from contract pharmacies.
Unassigned Identifiers Group
The Unassigned group contains identifiers that appear on purchases or submitted claims but are not assigned to a single pharmacy or dispensing location.
This may include identifiers that are:
Associated with both a contract pharmacy and a CE owned pharmacy or clinic.
Not currently mapped to a contract pharmacy or a CE owned pharmacy or clinic.
Covered entities must review these identifiers and reassign them to the appropriate contract pharmacy or CE owned pharmacy or clinic location to ensure purchases link to respective claims.
Note: Unassigned identifiers are a direct risk factor for an account becoming At Risk or Suspended in Purchase Validation, since 340B ESP cannot connect the purchase to the claim without a resolved mapping — see Purchase Validation Overview for how this connects to account eligibility.
What are pharmacy group details?
The Pharmacy Group Details page provides a detailed view of the selected pharmacy group and the identifiers associated with it. This view shows which pharmacies belong to the group, which identifiers are mapped to each pharmacy, and whether any identifiers are pending transfer or assignment.
This section is organized across the Pharmacies and Mapping Request tabs, which support reviewing current mappings and monitoring identifier transfer activity.
Pharmacies tab
The Pharmacies tab displays all active 340B contract pharmacies or CE Pharmacies and Clinics listed under your covered entities' HRSA arrangements and the identifiers associated with each pharmacy.
The table includes the following information:
Pharmacy – The Pharmacy column lists each pharmacy in the group. Beneath each pharmacy, the table displays the individual identifiers associated with that pharmacy, such as HIN, DEA, or NPI.
Associated Identifiers – The Associated Identifiers column shows the total number of identifiers associated with the pharmacy. Beneath that total, each identifier row lists the identifier type that corresponds with the identifier number. If an identifier is currently being transferred, the row may also indicate that the identifier is Pending Transfer.
Actions – Includes options for updating identifier mapping when changes are needed. Depending on the row, actions may include transferring a single identifier, viewing the status of a pending transfer, or transferring all identifiers associated with a pharmacy.
Identifier transfers are reflected in the Pending Identifiers tab when they are awaiting completion or review.
Note: If a pharmacy is listed as having no identifiers, please review your HRSA arrangements to confirm the pharmacy information is accurate and up to date by adding or transferring the applicable identifiers. For guidance on adding, transferring, and reviewing identifiers, see How to Transfer an Identifier.
Mapping Requests
The Mapping Requests tab displays identifiers that are currently awaiting transfer or reassignment from one group to another. Use this tab to monitor pending identifier changes as well as review a request history of past requests.
The table includes the following information:
Identifier – The identifier number that is pending transfer or reassignment. This may be a DEA, HIN, or NPI used to associate purchases and submitted claims with an account.
Status – Indicates where the mapping request is in the review process. A request may be In Review, Completed, or Denied.
Previous Group – The group where the identifier is was mapped prior to its requested reassignment.
New Group – The group where the identifier is expected to be reassigned once the pending transfer is complete.
Request Date – The date the identifier transfer or reassignment request was submitted.
Once a request is submitted, it is sent for review. You can use the Mapping Requests tab to monitor the request until it is completed or denied. You will receive an email notification with the decision. If the request is approved, the identifier will be mapped to the selected pharmacy.
