Added years

The years added to the ‘actual membership years’ to enhance the benefits for the member of a defined benefit scheme. It may be the outcome of a transfer payment received by the pension scheme, an additional voluntary contribution, or the employer or the scheme improving the member’s benefits.

Addition to age

A method used by life underwriters when charging an extra premium to under average lives. The underwriter adds a number of years to the proposer’s age in order to determine the actual premium that will be charged.

Additional benefits

Health care services not covered by Medicare and reductions in premiums or cost sharing for Medicare-covered services. Additional benefits are specified by the Medicare Advantage (MA) Organization and are offered to Medicare beneficiaries at no additional premium. Those benefits must be at least equal in value to the adjusted excess amount calculated in the adjusted or average community rate (ACR). An excess amount is created when the average payment rate exceeds the adjusted community rate (as reduced by the actuarial value of coinsurance, copayments, and deductibles under Parts A and B of Medicare). The excess amount is then adjusted for any contributions to a stabilization fund. The remainder is the adjusted excess, which is used to pay for services not covered by Medicare and/or is used to reduce charges otherwise allowed for Medicare-covered services. Additional benefits can be subject to cost sharing by plan enrollees. Additional benefits can also be different for each MA plan offered to Medicare beneficiaries.
