Will, who was age 65 in 4/95, did not enroll in SMI until 3/97. He was assessed a
10% premium surcharge when SMI became effective in 7/97. He also enrolled in an MMCP
in 7/97. He terminated his MMCP enrollment effective with 12/31/98 and enrolled in
Premium-HI during the 1999 GEP. His Premium-HI premium was increased by 10%, payable
for 6 years because there were 44 months (3 full years) that elapsed between the end
of his IEP and the GEP in which he enrolled (8/95 – 3/99).
In 6/00, he applied for a premium surcharge rollback because of his enrollment in
the MMCP. His Premium-HI surcharge remains at 10 percent, but the period of time for
which it is payable is reduced to 4 years. The 18 months from 7/97 through 12 /98,
during which he was enrolled in an MMCP, were subtracted from the 44 months that elapsed
after his IEP and through the end of the 1999 GEP, leaving 26 chargeable months (2
full years, instead of 3 full years).
