CMS Overview

The Centers for Medicare & Medicaid Services (CMS), a federal agency within the U.S. Department of Health and Human Services, is one of the largest purchasers of health care in the world. Medicare, Medicaid, and the Children's Health Insurance Program (CHIP) provide health care for one in four Americans. The United States Government does not discriminate in employment on the basis of race, color, religion, sex (including pregnancy and gender identity), national origin, political affiliation, sexual orientation, marital status, disability, genetic information, age, membership in an employee organization, retaliation, parental status, military service, or other non-merit factor. Federal agencies must provide reasonable accommodation to applicants with disabilities where appropriate. https://www.cms.gov/about-cms/careers-cms/diversity-equity-and-inclusion
