Entitlement to Hospital Insurance (HI) under Environmental Health Hazards (EHH) Medicare
can exist concurrently with HI entitlement based on age, disability, or ESRD. It is
advantageous for a beneficiary entitled to HI based on age, disability, or ESRD to
file an application for EHH Medicare if any one of the following applies:
The beneficiary is not currently enrolled in Supplementary Medical Insurance (SMI);
The beneficiary is paying a SMI premium surcharge because of late enrollment;
The date of entitlement to EHH Medicare would be earlier than the date of entitlement
to Medicare based on other criteria; or
The beneficiary, who is enrolled in Premium HI, Premium HI and SMI, or SMI only, can
now receive free HI.
NOTE: A beneficiary who already has Medicare based on age, disability, or ESRD may choose
to apply for EHH Medicare to have his or her record reflect entitlement to Medicare
based on EHH.
