The Centers for Medicare & Medicaid Services (CMS) has made a reasonable effort to ensure that the provided data/records/reports are up-to-date, accurate, complete, and comprehensive at the time of disclosure. This information reflects data as reported to the Healthcare Cost Report Information System (HCRIS). These reports are a true and accurate representation of the data on file at CMS. Authenticated information is only accurate as of the point in time of validation and verification. CMS is not responsible for data that is misrepresented, misinterpreted or altered in any way. Derived conclusions and analysis generated from this data are not to be considered attributable to CMS or HCRIS.

While health plan information including benefits, copayments, premiums, and geographic coverage is publicly available on Healthcare.gov, CMS also publishes downloadable public use files (PUFs) so that researchers and other stakeholders can more easily access Exchange data.

The POS file contains data on characteristics of hospitals and other types of healthcare facilities, including the name and address of the facility and the type of Medicare services the facility provides, among other information. The data are collected through the Centers for Medicare & Medicaid Services (CMS) Regional Offices. The file contains an individual record for each Medicare-approved provider and is updated quarterly. The data is an invaluable resource to a variety of stakeholders, including researchers and application developers.

The Fiscal Intermediary maintains the Provider Specific File (PSF). The file contains information about the facts specific to the provider that affects computations for the Prospective Payment System. The Provider Specific files in text format are located in the Download section below for the following provider-types:

The Medicare Current Beneficiary Survey (MCBS) is a continuous, multipurpose survey of a nationally representative sample of the Medicare population, conducted by the Office of Enterprise Data and Analytics (OEDA) of the Centers for Medicare & Medicaid Services (CMS) through a contract with NORC at the University of Chicago. The central goals of the MCBS are to determine expenditures and sources of payment for all services used by Medicare beneficiaries, including co-payments, deductibles, and non-covered services; to ascertain all types of health insurance coverage and relate coverage to sources of payment; and to trace outcomes over time, such as changes in health status and spending down to Medicaid eligibility and the impacts of Medicare program changes on satisfaction with care and usual source of care.

The Medicare Health Outcomes Survey (HOS) is the first patient-reported outcomes measure used in Medicare managed care. The goal of the Medicare HOS is to gather valid, reliable, and clinically meaningful health status data from the Medicare Advantage (MA) program to use in quality improvement activities, pay for performance, program oversight, public reporting, and to improve health. All managed care organizations with Medicare contracts must participate. The HOS is administered annually to a random sample of Medicare beneficiaries drawn from each participating MA plan and surveyed in the spring (i.e., a baseline survey is administered to a new cohort, or group, each year). Two years later, these same respondents are surveyed again (i.e., follow up measurement). The baseline sample size is twelve hundred. Cohort 1 was surveyed in 1998 and was re-surveyed in 2000. During the 2016 HOS administration, Cohort 19 was surveyed (baseline) and Cohort 17 re-surveyed (follow-up).

The CMS Drug Spending Dashboards are interactive, web-based tools that provide spending information for drugs in the Medicare Part B and D programs as well as Medicaid. The Dashboards focus on average spending per dosage unit and change in average spending per dosage unit over time. The tools also include additional manufacturer-level drug spending information as well as consumer-friendly descriptions of the drug uses and clinical indications.

CMS is committed to increasing access to its Medicare claims data through the release of de-identified data files available for public use. These files are available to researchers as free downloads in CSV format. They contain non-identifiable claim-specific information and are within the public domain.

This release contains the Chronic Conditions Public Use Files (PUF) with information from Medicare claims. The CMS Chronic Conditions PUF is an aggregated file in which each record is a profile or cell defined by the characteristics of Medicare beneficiaries. A profile is defined by all combinations of age category, gender, various chronic conditions, and dual-eligibility status of the beneficiaries. Hence, the number of rows (or records) in a CMS Chronic Conditions PUF represents the number of unique profiles in the Medicare population. For each profile many claim-related variables are provided in the form of averages.

The CMS Chronic Conditions PUF represents 100% of the Medicare beneficiaries provided in the 100% Beneficiary Summary File for each reference year. The 100% Beneficiary Summary File is created annually and contains demographic, entitlement and enrollment data for beneficiaries who were: documented as being alive for some part of the reference year of the Beneficiary Summary File, are entitled to Medicare benefits during the reference year, and enrolled in Medicare Part A and/or Part B for at least one month in the reference year.

"Public-use data files are prepared and disseminated to provide access to the full scope of the data. This allows researchers to manipulate the data in a format appropriate for their analyses."

The Department of Health & Human Services is responsible for the collection of information on a range of health related issues. The information is collected to monitor the general health and well-being of Michigan's citizens. These data are useful for health program development, targeting and evaluation of program progress. The information is used to identify emerging health issues and trends and can be made available for epidemiological research. Statistics are developed from the data collected to provide basic information on these health events in Michigan. The data are provided at the state, county and community level. Listed below are the categories of available statistics.

The Comprehensive Epidemiologic Data Resource (CEDR) is the U.S. Department of Energy (DOE) electronic database comprised of health studies of DOE contract workers and environmental studies of areas surrounding DOE facilities. DOE recognizes the benefits of data sharing and supports the public's right to know about worker and community health risks. CEDR provides independent researchers and educators with access to de-identified data collected since the Department's early production years. Current CEDR holdings include more than 76 studies of over 1 million workers at 31 DOE sites. Access to these data is at no cost to the user.

Most of CEDR's holdings are derived from epidemiologic studies of DOE workers at many large nuclear weapons plants, such as Hanford, Los Alamos, the Oak Ridge reservation, Savannah River Site, and Rocky Flats. These studies have primarily used death certificate information to identify excess deaths and patterns of disease among workers to determine what factors contribute to the risk of developing cancer and other illnesses. In addition, many of these studies have radiation exposure measurements on individual workers.
