The HI surcharge exists only for a period equal to twice the number of months in each
full 12-month period during which the individual could have been, but was not, enrolled
in Premium-HI. Thus, some individuals who start 1994 with a surcharge will have the
surcharge removed by the end of the year.
NOTE: The number of months in excess of 12 does not, as in SMI, determine the percentage
to be assessed as the surcharge.
