Concerning high aggregate cost for long-term care service, my father, who lives with me, is covered under Medical Care System for the Advanced Elderly. Can his copayment be included in the aggregate total too?

Since under the medical insurance system insured persons covered under Medical Care System for the Advanced Elderly are not considered to be part of the same household as insured persons under other plans, in this case your father's copayment cannot be included in the aggregate total.

Howeber, if your father was your dependent for any period during the calculation period, his copayment for that period can be included in the aggregate total.
