Healthcare cost trend rate requires a named plan, population, date, and evidence owner. The healthcare cost trend rate estimates future per-capita changes in covered healthcare costs. Preserve the initial rate, decline pattern, ultimate rate, year reached, covered cost base, and actuarial model.

Apply it

A one-percentage-point sensitivity supplied by the actuary shows the conditional effect on APBO and service-plus-interest cost. It does not mean every medical claim rises by one percent.

Common mistake

Do not assume that the healthcare trend rate is a single permanent inflation rate. The assumption can follow a stated path to an ultimate rate and must reflect the plan's covered costs and cost sharing. That error would misstate benefit cash flows by ignoring the supported path to an ultimate rate.

Keep the boundary clear

Participant cost sharing, caps, subsidies, utilization, and government-program interactions can change the result. Accounting reviews the evidence but does not select the trend path.

Authority

Read ASC 715-60-35-99 for the healthcare cost trend assumption.
