People with Medicare

Welcome to the Beneficiary section of the Wisconsin Physicians Service (WPS) Government Health Administrators (GHA) website.

Medicare is a federally funded health insurance program for people 65 years of age and older, certain disabled people, and people with end-stage renal disease (permanent kidney failure). WPS GHA was chosen by the Centers for Medicare & Medicaid Services (CMS) to administer the Medicare program in the states of Indiana, Iowa, Kansas, Michigan, Missouri, and Nebraska. We also administer Medicare Part A services in several other states.

For the complete information about the Medicare program, visit the Official U.S. Government Site for People with Medicare, which is found at There you will find helpful information about covered services, participating providers, prescription drugs, claim billing, and appeals. You will also find official Medicare publications and personalized Medicare information.

If you need to speak to someone about Medicare, or if you have questions about Medicare claims or services, please call 1-800-MEDICARE (1-800-633-4227). For TTY/TDD, call (877) 486-2048.
