Magnetic Resonance Imaging (MRI) is covered by the Medicaid program except for uses contraindicated by the Centers for Medicare and Medicaid Services. MRI use is not covered for patients with certain types of pacemakers, metallic clips or for procedures involving certain bones and calcifications, according to the National Determinations Manual.
The Centers for Medicare and Medicaid Services, or CMS, administer the Medicare and Medicaid programs. CMS determines the efficacy of new medical techniques and technologies before providing coverage under federal health programs. The CMS determination can include uses indicated for specific ailments, contraindications in which the technique should not be used or general eligibility that allows local Medicare administrative contractors to make case-specific determinations.
