Access to cancer drugs in Medicare Part D: formulary placement and beneficiary cost sharing in 2006

The Medicare Part D benefit expands the universe of cancer drugs and biologics that Medicare may cover. Individual Part D plans have discretion to determine their formularies and cost sharing for drugs within federal guidelines. This paper analyzes differences in coverage and cost sharing for cancer drugs among these plans. We find that many cancer drugs, including brand-name products, are covered by almost all plans, although prior authorization might limit access to some. In addition, many plans charge a relatively low copayment for most cancer drugs. These findings suggest that Part D could greatly expand beneficiaries' access to cancer treatments.     

Hospital market share: the declining share of small players in the market

Analysis of a set of isolated hospital markets reveals that low-market-share hospitals have experienced a consistent decline in their market share for the last five years. The challenges presented by such a decline in market share are compounded by the overall decline in the total market (in terms of number of hospital discharges) for the markets studied. It is suggested that significant strategy changes may be required if low-market-share hospitals are to survive.     

Trends in Medicare health maintenance organization enrollment: 1986-93

This study examines Medicare health maintenance organization (HMO) enrollment under the Tax Equity and Fiscal Responsibility Act (TEFRA) of 1982 (Public Law 97-248) from 1986 to 1993. It shows that there was moderate growth in the number of Medicare beneficiaries participating in the TEFRA risk program, reaching 1 in 20 beneficiaries in 1993. Medicare HMO enrollment is heavily concentrated in a few large plans, resulting in heavy concentrations geographically. California and Florida accounted for over one-third of Medicare HMO enrollees. One-half of the States have no Medicare HMO enrollment and one-fifth of the States have fewer than 15,000 Medicare HMO enrollees.     

Geographic variation in determinants of Medicare managed care enrollment

OBJECTIVE: To examine the effect of adjusted average per capita cost (AAPCC) rate and volatility on Medicare risk plan enrollment at the county level. DATA SOURCES: Secondary data from the Health Care Financing Administration's office of managed care and other sources were merged to create comprehensive data on all Medicare risk plans in 3,069 of the 3,112 U. S. counties in December 1996. STUDY DESIGN: A two-step least squares regression was estimated to examine the effects of AAPCC rate and volatility, commercial HMO enrollment, market factors, and characteristics of the county population on Medicare HMO enrollment. The model was also used to simulate the effects of the Balanced Budget Act of 1997. Data from the Health Care Financing Administration were merged with other sources at the county level. The Federal Information Processing Standards code and a crosswalk file matching that code with the county name linked the data across sources. PRINCIPLE FINDINGS: The AAPCC rate has a small positive effect on the probability of Medicare HMO availability and enrollment. However, commercial HMO enrollment has a much stronger positive effect on Medicare HMO enrollment. Volatility has a negative effect on the probability of any Medicare HMO enrollment. CONCLUSIONS: The results suggest that payment changes enacted as part of the Balanced Budget Act will have a limited effect on Medicare HMO enrollment, especially in rural areas. Other policy changes are needed to stimulate Medicare HMO enrollment.
