Medicare dual eligible

Medicare dual eligibles, in the Medicare system of the United States, are Medicare Part A and/or B recipients who either [1] qualify for a Medicare Savings Programs (MSP) or [2] qualify for Medicaid benefits. Dual eligibles generally qualify for the QMB benefits, in which the beneficiary's non-Medicare coverage is covered by Medicaid, effectively providing full health care coverage. With the advent of the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, these dual eligibles have automatically been enrolled to a random Medicare Part D plan, effective January 1 of 2006. As a result of this auto assignment, participants who were already enrolled in a Medicare Advantage HMO, may have been automatically disenrolled from their medical plan to allow for part D enrollment. Medicaid will still cover drugs for dual-eligible patients that are not covered by Medicare Part D, including certain controlled substances. Pharmacies know by automation who these patients are.
