The Enrollment/Disenrollment Process
Gateway Health Plan Medicare Assured® HMO is a Health Maintenance Organization (HMO) for people with Medicare Part A, Medicare Part B and Medicaid. Most Medicare plans have certain times of the year, called election or special election periods, when a person can apply or disenroll. Gateway Health Plan's Medicare Assured® HMO is a Special Needs Plan (SNP), which must allow the applicant to enroll or disenroll at any time during the year.
Members can enroll into our plan by:
- A paper enrollment form
- On-line forms through CMS’s website
- Gateway’s website at www.gatewayhealthplan.com
- By calling Gateway Health Plan® at 1-877-GATEWAY.
Members can disenroll from our plan by completing a paper disenrollment form, sending a letter/fax to Gateway Health Plan Medicare Assured® HMO, writing a letter to Social Security or Railroad Retirement Board or by calling 1-800-Medicare. Members may also disenroll from Gateway Health Plan Medicare Assured® HMO by simply enrolling in another HMO.
Members that enroll and disenroll are made effective the first day of the calendar month.

Member ID Cards
Each Medicare Assured® HMO member will receive an ID card. Each card is issued once, unless cards are requested or reissued due to a change. ID Cards are good for as long as the person is a member of Gateway Health Plan Medicare Assured® HMO. (Sample ID cards below).

Members age 21 and over will need to use their Gateway Health Plan Medicare Assured® HMO ID card and keep their Medicaid Access card to use for services covered under Medical Assistance and to cover their Medicare deductibles and coinsurance, as long as the provider also participates with Medicaid.
Members under the age of 21 will use their Gateway Health Plan Medicare Assured® HMO ID card and their Gateway Health Plan® Medicaid card. These members will need to keep their Medicaid Access card for non-Medical assistance services, such as transportation through the Medical Assistance Transportation Program (MATP) or cash assistance.

Primary Care Practitioner’s Role in Determining Eligibility
Primary care practitioners verify eligibility by consulting their panel listing in order to confirm that the member is a part of the practitioner’s panel. The panel list is distributed on or about the first of every month. The primary care practitioner should check the panel list each time a member is seen in the office. If a member’s name is on the panel list, the member is eligible with Gateway for that month.
If members insist they are effective, but do not appear on the panel list, the practitioner should call the Gateway Health Plan Medicare Assured® HMO Provider Services Department for help in determining eligibility. (Refer to the Quick Reference section in this manual for phone number.)
