NPDB Data

Introduction

The Data Analysis Tool (DAT) allows you to generate datasets for Adverse Action Report (AAR) and Medical Malpractice Payment Report (MMPR) data for 1990 through June 30, 2024. You may tailor your data by using the filters available or by clicking on the map or graph. Hover over a state on the map to see detailed information for that state.

The second tab shows the number of unique practitioners for each profession (practitioner type) in the NPDB and the sum of unique practitioners per state.

Reset the dashboard to its original view by clicking Reset. Additionally, you can download the data as a CSV file.

Note: This file does not include any information that identifies individual practitioners or reporting entities. The file is designed to provide data for statistical reporting and analysis only.

Federal law (42 U.S.C. § 11137(b)) requires HRSA to present the data in this file in a form that does not permit use of the data alone, or in combination with other available information, to identify any particular health care entity, physician, other health care practitioner, or patient. Therefore, as a condition of obtaining access to the data, users agree:

  1. To not use the dataset alone or in combination with other data to identify any individual or entity or otherwise link information from this file with information in another dataset in a manner that includes the identity of an individual or entity;
  2. The dataset can only be used in connection with statistical reporting or analysis.

By using these data, you signify your agreement to comply with the conditions stated above.

Due to the 30 day reporting window, actions taken by entities at the end of a quarter may not be reported to the NPDB until the following quarter. Actions taken during Q4 may not be reported until Q1; therefore the annual data will not be final until the Q1 data are added.

Less than 500 Medical Malpractice Payment Reports from 1990–2003 are not represented on this page due to not including either state or profession information.

Methods

Data Collection

The National Practitioner Data Bank (NPDB) routinely collects information relating to medical malpractice payments and certain adverse actions taken by hospitals and other health care entities, professional societies, health plans, peer review organizations, private accreditation organizations, Federal and State licensing and certification authorities, and certain other Federal and State agencies. More information about the NPDB can be found in About Us. The report level data used in this data analysis application reflect medical malpractice payment and adverse action information, including state licensure and certification actions, clinical privileges/panel membership and professional society membership actions, and HHS/OIG and DEA actions. The term "unique practitioner" is used under the NPDB Practitioners tab to denote the following: one practitioner can be counted in multiple types and in multiple states, which would cause a summation of either category to be greater than the actual unique practitioner count.

Legislation and Regulations

The Health Care Quality Improvement Act of 1986 (HCQIA), as amended, Title IV of Public Law 99-660 (42 U.S.C. 11101 et seq.), led to the establishment of the National Practitioner Data Bank (NPDB). Title IV authorized the NPDB to collect and disclose to authorized queriers certain information relating to the professional competence and conduct of physicians, dentists, and other health care practitioners. Subsequent laws later expanded the information collected and disclosed by the NPDB and modified its operations. Most recently, Congress passed Section 6403 of the Patient Protection and Affordable Care Act of 2010, Public Law 111-148 to eliminate duplication between the NPDB and the Healthcare Integrity and Protection Data Bank (HIPDB). On May 6, 2013, NPDB operations were consolidated with those of the former HIPDB. As a result of this consolidation, information previously collected and disclosed by the HIPDB is now collected and disclosed by the NPDB. This legislation established the NPDB as the single Data Bank to receive and disclose information collected under Title IV, Section 1921 of the Social Security Act, and Section 1128E of the Social Security Act. Information is available to eligible entities based on the requirements of each law. As of May 6, 2013, this Data Analysis Tool contains practitioner reports received by the NPDB and includes state licensure and certification actions, clinical privileges/panel membership and professional society membership actions, and HHS/OIG and DEA actions.

Information reported to the NPDB is confidential and can be provided only to authorized queriers, based on their eligibility to receive the information under each of the three laws. Authorized queriers include hospitals, other health care entities with formal peer review, professional societies with formal peer review, quality improvement organizations, health plans, state licensing and certification authorities, Federal licensing and certification agencies, state law enforcement agencies, state agencies administering State health care programs, state Medicaid Fraud Units, agencies or contractors administering Federal health care programs, U.S. Comptroller General, Federal law enforcement agencies and officials, health care practitioners and health care entities, providers and suppliers (self-query), and plaintiff's attorney/pro se plaintiffs (under limited circumstances).

Under section 426 of the HCQIA (42 USC 11135), as implemented by regulations at 45 CFR part 60.13(a)(2)(ix), data may be released to "a person or entity who requests information in a form which does not permit the identification of any particular health care entity, physician, dentist, or other health care practitioner." This information is released in accordance with that provision to facilitate research use of NPDB information by persons interested in medical malpractice, licensing, discipline, and quality assurance issues.
