HRS Medicare Claims and Summary Data
Overview
One of the main goals of the Health and Retirement Study
is to understand the relationship between medical history and financial status, and how use of health
care may change as people age. To assist in this effort, the HRS endeavors to obtain information about
health care costs and diagnoses from Medicare records maintained by the Centers for Medicare and
Medicaid Services (formerly the Health Care Financing Administration). The HRS asks all respondents
who are eligible for Medicare to provide their identification numbers; over 80% of them consent do so.
| Medicare Data File Descriptions, 1993-2005 |
| File Name | Description |
| Inpatient SAF | The Inpatient Standard Analytical File (SAF) contains final action claims data submitted by inpatient hospital providers for reimbursement of facility costs. Some of the information contained in this file includes diagnosis, (ICD-9 diagnosis code), procedure (ICD-9 procedure code), Diagnosis Related Group (DRG), dates of service, reimbursement amount, hospital provider, and beneficiary demographic information. Each observation in this file is at the claim level. |
| Skilled Nursing Facility SAF | The Skilled Nursing Facility (SNF) SAF contains final action claims data submitted by SNF providers. |
| Outpatient SAF | The Outpatient SAF contains final action claims data submitted by institutional outpatient providers. Examples of institutional outpatient providers include hospital outpatient departments, rural health clinics, renal dialysis facilities, outpatient rehabilitation facilities, comprehensive outpatient rehabilitation facilities, and community mental health centers. |
| Home Health Agency SAF | The Home Health Agency (HHA) SAF contains final action claims data submitted by HHA providers. |
| Carrier SAF | The Carrier SAF (old file name Physician/Supplier Part B) contains final action claims data submitted by non-institutional providers. Examples of non-institutional providers include physicians, physician assistants, clinical social workers, nurse practitioners, independent clinical laboratories, ambulance providers, and free-standing ambulatory surgical centers. |
| Hospice SAF | The Hospice SAF contains final action claims data submitted by Hospice providers. |
| Durable Medical Equipment | The Durable Medical Equipment (DME) contains final action claims data submitted by Durable Medical Equipment suppliers. |
| MedPAR | The MedPAR File contains inpatient hospital and skilled nursing facility (SNF) final action stay records. Each MedPAR record represents a stay in an inpatient hospital or SNF. An inpatient "stay" record summarizes all services rendered to a beneficiary from the time of admission through discharge. |
| Denominator | The Denominator File contains demographic and enrollment information about each beneficiary enrolled in Medicare during a calendar year. The Denominator File is used to determine beneficiary entitlement, and beneficiary participation in Medicare Managed Care Organizations. |
Summary of the Medicare Data Release Process
In order to use the Medicare records linked to HRS respondents, there are two linked approval processes that must be completed. As a first step, users should obtain approval from HRS for the use of restricted data (see below).As a second step,
users should obtain a Data Use Agreement (DUA) from the Centers for Medicare & Medicaid Services (CMS), working through the Research Data Assistance Center (ResDAC). Formally, the request for a DUA from CMS must come from the program officer of the funding agency that supports your research.
Application Procedures
Negotiating a CMS Data Use Agreement
- User applies to HRS for restricted data approval (see below).
- While application is under review by HRS, user completes a data request packet (New Use Request) for CMS. A complete description of the required documentation can be found at the ResDAC
Requesting CMS's Identifiable Data Files (RIFs) - New Use Requests page:
(http://www.resdac.umn.edu/Medicare/requesting_data_NewUse.asp)
- User receives PRELIMINARY approval from HRS.
- User finalizes CMS data request packet, incorporating data plan approved by HRS, and sends all paperwork, including HRS approval, to Acumen, LLC.
- Acumen verifies, completes, and sends the request to the funding agency
- Funding agency signs off on the request and forwards to CMS.
- CMS approves data request and notifies user, the Research Data Distribution Center (RDDC) at Acumen, and HRS.
- RDDC sends a CD containing the Medicare data files to user (encrypted).
- HRS provides user with ID cross-reference file (encrypted) that links respondents to the record set created by Acumen.
