Disabled Medicare beneficiaries in HMOs.

This study presents new data from a 1996 national survey of Medicare risk enrollees and disenrollees designed to profile access to care in Medicare health maintenance organizations (HMOs). The findings show that expanded benefits and low (or no) premiums are major features attracting disabled Medicare beneficiaries into Medicare HMOs. We found that most disabled persons enrolled in Medicare HMOs do not experience access problems. However, they are more likely than nondisabled Medicare HMO enrollees to experience such problems. We conclude by highlighting the importance of having information to monitor access to care for vulnerable subgroups such as disabled Medicare beneficiaries and to develop incentives to serve them well in Medicare HMOs.
