Billing & Fees

The NPDB does not receive federal funding (appropriations) to support its operations. Therefore, according to federal law the fees charged by the NPDB must cover the cost of operations. Any changes to NPDB fees are announced by the Secretary of HHS in the Federal Register.

Major credit cards, debit cards, or electronic funds transfers (EFT) are accepted as payment. Online payments are safe and secure.

Continuous Query

The annual enrollment fee of $2.50 for Continuous Query covers the cost of enrolling one practitioner in the NPDB for one year.

One-Time Query

The cost of performing a One-Time Query is $2.50 for each query submitted.


A $3.00 fee is charged per digitally certified Self-Query. Mailed paper copies of Self-Queries are an additional $3.00 each.

Note: Fees are charged for queries that are successfully processed by the NPDB, and queries are not charged if rejected because they are improperly submitted or incomplete.
