An individual who is not subject to Part A buy-in as discussed in HI 00801.140 may only enroll for Premium-HI during the
Initial Enrollment Period (IEP): the IEP begins 3 months before the first month of
eligibility (generally, the month of attainment of age 65; see HI 00801.131 C. for exceptions) and continues for 7 months. Coverage based on an IEP enrollment begins
as provided for in HI 00805.165. The IEP for Premium-HI is generally the same as the IEP for SMI.
General Enrollment Period (GEP): the GEP is January through March of each year. Coverage
based on a GEP enrollment begins the following July 1.
Special Enrollment Period (SEP): the SEP is an enrollment opportunity for individuals
whose employer group health plan coverage based on current employment has ended. (See
HI 00805.265ff. for a complete discussion of the SEP provisions.)
Transfer Enrollment Period: This is a special enrollment opportunity for Medicare
beneficiaries who are also Health Maintenance Organization (HMO) or Competitive Medical
Plan (CMP) enrollees and whose HMO or CMP enrollment is terminated either on a voluntary
basis or because of termination of the HMO or CMP contract. (See HI 00801.143 for further discussion.)
