For more detailed information on “What is Medicare?” and “When do I enroll in Medicare?” please contact Medicare at 1-800-Medicare (1-800-633-4227), (TTY 1-877-486-2048), or at www.medicare.gov.

Important Note: Subject to limited exceptions, Postal Service annuitants entitled to Medicare Part A and their eligible family members who are entitled to Medicare Part A are required to enroll in Medicare Part B to maintain eligibility for the PSHB Program in retirement.

If you are required to enroll in Medicare Part B and fail to do so at your first opportunity, you may be disenrolled (annuitants) and/or your family members removed from coverage.

For more information on these requirements, please contact the number on the back of your ID card.
