N.M. Admin. Code § 8.240.400.9
To be eligible for the qualified medicare beneficiaries program (QMB), an applicant/recipient must be covered by medicare part A. Medicare part A is a free entitlement to social security beneficiaries who are 65 years of age or older or who have received social security disability payments for 24 months. Fully or currently insured workers, or their dependents, who have end-stage renal disease are also covered under medicare.
Most applicants/recipients 65 years of age or older who do not receive free medicare part A can voluntarily enroll for hospital insurance coverage, with payment of a monthly premium. Voluntary enrollees must also enroll for supplementary medical insurance, medicare part B, and pay that premium, as well.
