Per-X-Years Limit
A per-X-years limit means a benefit can only be claimed once during a specified number of years. This rule applies to items or treatments that are not needed annually, such as hearing aids, orthotics, or major dental appliances.
How It Works
A per-X-years limit is a benefit maximum that applies over a multi-year period instead of resetting every benefit year, so a service might be covered only once every two years. While most coverage maximums on a personal health plan are stated per calendar year for each insured person, some maximums use a multi-year window instead. For one of these multi-year maximums, the period begins on the day the insured person first incurs an expense under that maximum, rather than on a fixed calendar date. This kind of frequency or per-period limit restricts how often a service is covered, which is different from an annual dollar maximum that caps the total amount a plan will pay over a benefit period. In dental plans, these limits are often expressed by time or frequency, capping the number of procedures permitted during a stated period, such as no more than two cleanings in twelve months or one cleaning every six months.
Example:
A Canadian personal health plan might cover prescription eyewear, but make the benefit eligible only once every two years rather than annually. If you claim new glasses this year, you generally will not be eligible to claim prescription eyewear again until two years have passed, even though other benefits like dental cleanings reset on their own schedule.
What to Watch For:
Once a frequency-limited benefit has been used for its allowed period, you are responsible for any further charges until the next eligible period, and major services may require predetermination to confirm coverage. Keep in mind that per-period maximums often coexist with other limit types on the same plan, since a single benefit can carry both an annual cap and additional sub-limits such as per-visit caps. Multi-year frequency limits are common for benefits such as vision care, where a plan may make prescription eyewear eligible only every two years.
