Front-end validations are the first set of checks Beacon performs on pharmacy and medical claim submissions before any data is ingested into the platform. These validations ensure claims include required data fields, meet formatting specifications, and reference eligible entities and products.
What Are Front-end Validations?
Front-end validations take place before Beacon accepts a file for processing, whether claims are submitted through the web application or via the SDK. These validations prevent invalid or incomplete 340B claims from entering the system and ensure that data aligns with HRSA requirements and manufacturer policies governing the 340B Rebate Model Pilot Program.
Front-end validations are designed to:
Confirm the submission includes only 340B-eligible products.
Ensure the submitting user is authorized to submit for the covered entity.
Verify data types, formats, and field lengths.
Confirm that all required fields are present.
Only claims that pass all front-end validations proceed to ingestion and subsequent back-end validations.
Tip: For a detailed list of front-end validation requirements and accepted formats, check out Pharmacy Claims Requirements Data Table and Medical Claims Requirements Data Table.
Types of Front-end Validations
Beacon performs four primary types of front-end validations:
Ineligible Products
Front-end checks verify whether the NDC included in a claim is part of HRSA’s 340B Rebate Model Pilot Program.
Claims containing ineligible NDCs are filtered out and not ingested.
Only claims for eligible products proceed.
This does not block other valid claims within the same file.
Covered entities can download the eligible NDC list from Beacon’s Resources page.
Invalid Entity
Beacon verifies whether the 340B ID included in the submission is associated with the user’s registered entities.
Hospitals submit at the parent 340B ID level. All child sites fall under the parent and are valid for submission.
Grantee sites must be registered individually.
Claims submitted for a 340B ID not linked to the user’s account are filtered out, but other valid rows continue .
Invalid Data Types
These validations ensure that each field follows the required data type and format. Examples include:
Alphabetic characters in numeric fields.
Dates submitted in nonstandard formats.
Values exceeding allowed fields lengths.
Decimal values where decimals are not permitted.
Invalid data types block ingestion, and users are shown the specific fields that need correction.
Invalid Data Values
Because front-end validations in the web application occur locally on the user’s machine, only a limited number of value checks are executed for performance reasons.
Beacon currently verifies:
Whether NPIs in the Prescriber ID and Service Provider ID pass required checksum logic.
Whether values are formatted correctly and structurally valid.
Invalid values must be corrected before the files can be resubmitted.
Missing Data Elements
HRSA has designated specific fields as mandatory for both pharmacy and medical claims. Beacon only accepts 340B claims submissions that include all of the required fields as defined by HRSA.
Missing any required fields results in a front-end validation failure.
Beacon displays the exact fields that must be added or corrected.
Only complete claims move forward to back-end validation.
Front-end validations represent the first layer of data quality and compliance checks within the 340B rebates workflow. By preventing incomplete, incorrectly formatted, or ineligible claims from entering the system, these validations help ensure that only reliable and compliant data proceeds into Beacon. Once claim lines pass front-end validation, they move into ingestion and subsequent back-end validation.
