Matching MCBS (Medicare Current Beneficiary Survey) and Medicare data: the best of both worlds.

Survey reports from the Medicare Current Beneficiary Survey (MCBS) were matched to Medicare administrative files to create the 1992 MCBS Cost and Use file. This file improves on previous MCBS Access-to-Care user files by representing the entire (ever enrolled) Medicare population and including services not covered by Medicare such as outpatient prescription drugs and long-term facility care. The matching and reconciliation process improved the accuracy and completeness of health care use and cost. For example, Medicare billing data corrected 22 percent of survey reports that did not record Medicare as a payer and 39 percent in which the amount was missing.

Medicare beneficiary information needs: 1994.

The Medicare Current Beneficiary Survey (MCBS) is a powerful tool for analyzing enrollees' access to medical care (Adler, 1994). Based on a stratified random sample, we can derive information about the health care use, expenditure, and financing of Medicare's 36 million enrollees. We can also learn about those enrollees' health status, living arrangements, and access to and satisfaction with care. In the charts that follow, we have presented some findings on enrollee information needs in 1994, number of beneficiaries with information needs met, and sources of information used by beneficiaries. These charts attempt to answer the following questions: What types of needs do our beneficiaries have? How well do our beneficiaries understand Medicare?

Ownership and average premiums for Medicare supplementary insurance policies.

This article describes private supplementary health insurance holdings and average premiums paid by Medicare enrollees. Data were collected as part of the 1992 Medicare Current Beneficiary Survey (MCBS). Data show the number of persons with insurance and average premiums paid by type of insurance held--individually purchased policies, employer-sponsored policies, or both. Distributions are shown for a variety of demographic, socioeconomic, and health status variables. Primary findings include: Seventy-eight percent of Medicare beneficiaries have private supplementary insurance; 25 percent of those with private insurance hold more than one policy. The average premium paid for private insurance in 1992 was $914.

Why more cost-sharing won't slow Medicare spending.

In considering ways to slow the growth in Medicare expenditures, policymakers have concluded that increasing point-of-service cost-sharing for patients will reduce demand for health services. Under the current system, Medicare beneficiaries faced with increased cost-sharing can reduce their demand for services or purchase additional private insurance. New data from the 1991 Medicare Current Beneficiary Survey show that high-income persons protect themselves from out-of-pocket costs by purchasing private supplemental insurance. Surprisingly, the data also reveal that many low-income persons also purchase private insurance, demonstrating that the elderly--whatever their income level--consider supplementary insurance more of a necessity than a luxury. Thus, it appears that increased beneficiary cost-sharing would have a limited effect on Medicare spending growth.

Health insurance and the elderly: data from MCBS (Medicare Current Beneficiary Survey).

This article shows the supplemental insurance distribution and Medicare spending per capita by insurance status for elderly persons in 1991. The data are from the Medicare Current Beneficiary Survey (MCBS) and Medicare bill records. Persons with Medicare only are a fairly small share of the elderly (11.4 percent). About three-fourths of the Medicare elderly have some form of private insurance. The share with Medicaid is 11.9 percent, which has increased recently as qualified Medicare beneficiaries (QMBs) started to receive partial Medicaid benefits. In general, Medicare per capita spending levels increase as supplemental insurance comes closer to first dollar coverage. When the data were recalculated to control for differences in reported health status between the insurance groups, essentially the same spending differences were observed.
