Annual limits, sub-limits, lifetime limits and waiting periods

A plan's headline limit tells you almost nothing about what it pays for a specific claim. IPMIBenefits explains the four kinds of limit on an international plan, how they interact, and which one to check for each benefit.

Four kinds of limit on every plan

Every international private medical insurance (IPMI) plan limits what it pays in four different ways, and they are easy to confuse because brochures lead with only one of them.

Annual maximum

The most the plan pays for one person in one policy year, across all benefits. Also called the overall annual limit or annual overall benefit maximum. Resets at renewal.

Sub-limit

The most the plan pays for one benefit within the year, inside the annual maximum. Outpatient, dental, maternity, wellness and therapies nearly always have one. Expressed as an amount, a number of sessions or days, or a percentage of the bill.

Lifetime limit

The most the plan pays for one benefit over the whole life of the policy, not per year. Used for benefits that are rare but very expensive or long-running: organ transplant, hospice care, some chronic conditions.

Waiting period

Not a limit on amount but on time: a stretch after your start date during which a benefit cannot be claimed at all. Longest for maternity, common for dental and wellness.

A plan with a very high annual maximum can still pay very little for a therapy session, a crown or a check-up, because those claims hit a sub-limit long before they approach the annual figure. The annual maximum protects you in a catastrophe; the sub-limits decide most ordinary claims.

The annual maximum: what it protects and what it does not

The annual maximum is the ceiling. Insurers publish it prominently because it is the simplest number to compare, and ladders of plans are usually built around it: each tier raises the maximum and adds benefits. Cigna Global, Now Health WorldCare, XN Global and Bupa Global all publish their ladders this way, with some top tiers described as paid in full or without an overall limit.

What the annual maximum does: it caps the plan's total exposure in a bad year. A long illness with surgery, intensive care and months of treatment is the case where it matters, and a low maximum can run out before the treatment does. Because such years are rare, a high maximum costs less than its importance, as the cost guide explains.

What it does not do: it does not tell you how much a specific benefit pays. Bupa Global makes the point on its own ladder, noting that its hospital-focused Major Medical plan has a higher annual limit than its Select and Premier plans, which include more day-to-day benefits. A higher maximum did not buy routine dental or maternity; the tier did. Two further details to check: whether the maximum is per person or per family, and whether it applies per policy year or per condition.

Sub-limits: the numbers that decide most claims

Sub-limits sit inside the annual maximum and apply to individual benefits. They are the reason to read the whole table rather than the first line. Typical forms:

• An amount per year. The outpatient limit, the dental limit, the wellness amount. Now Health SimpleCare states plainly that its annual maximum is not the limit for every benefit and that sub-limits sit in the regional brochures.
• An amount per event. A limit per pregnancy, per evacuation, or per course of treatment.
• Days or sessions. Inpatient psychiatric care limited by days per year, as XN Global publishes with day counts rising by tier; rehabilitation by days, as Bupa Global lists by plan; physiotherapy by sessions; home nursing by weeks, as IPH Emerald lists by level.
• A percentage. A benefit paid at a stated share of the bill, common for major dental and some therapies.
• An aggregate. A limit that several benefits share. XN Global's routine chronic management, for example, is paid at full refund subject to the plan's outpatient aggregate limit, so chronic care and ordinary outpatient claims draw from the same pool.

Sub-limits also nest. A plan may have an outpatient limit, within which prescriptions have their own limit, within which a single item is capped. When comparing, find the smallest limit that applies to the claim you care about; that is the effective limit.

Day-to-day benefits are where sub-limits bite hardest. See the outpatient, dental and optical, mental health and wellness pages for the sub-limits typical of each.

Lifetime limits: the ones that do not reset

A lifetime limit caps a benefit over the life of the policy rather than per year. It is used for treatment that is rare, expensive and sometimes recurring, where an insurer wants a firm ceiling. The benefits most often subject to a lifetime limit: organ transplant, hospice and terminal care, stem-cell treatment, and some chronic or congenital condition benefits. HCI Nimbl publishes lifetime limits for organ transplant and for hospice and terminal care in its core; IPH Emerald publishes lifetime limits for hospice and stem-cell treatment that rise by level.

A few plans apply a lifetime limit to the whole policy as well as an annual one. VUMI Global notes that some of its plans carry a lifetime maximum alongside the annual maximum, and that the two are not interchangeable when comparing headline figures. On a plan of that kind, a long illness across several years draws down the lifetime figure even though the annual figure resets.

Lifetime limits matter most for people who intend to keep a plan for decades, which is most expats. A modest lifetime limit on hospice care is unlikely to be tested; a lifetime limit on the whole policy is worth understanding before you commit to it for the long term.

Waiting periods: limits on time rather than money

A waiting period stops you claiming a benefit until a set time has passed since your start date. Insurers use it where a benefit could be bought the week before it is needed: maternity, routine dental, health checks, and sometimes mental health or specific procedures. Inpatient and emergency benefits rarely have one.

The lengths published by the insurers on this site show the range. IMG Global lists a 6-month wait for optional dental, with accidental damage covered immediately, and a 10-month wait for routine maternity. HCI Nimbl lists a 6-month wait for its dental module and a 12-month wait for maternity on group plans. Now Health WorldCare lists 9 months for dental on Excel and above and 12 months for maternity on Apex. Bupa Global lists 6 months for routine and major restorative dental, 10 months for health checks, and 18 months for maternity and assisted fertility on Elite and Ultimate. Exact periods are confirmed by each insurer at quote.

Three mechanics to understand:

• When the clock starts. Usually the date the benefit was added, not the date you first joined. Adding maternity at renewal restarts the maternity wait.
• Accidents and emergencies. Often exempt. Accidental dental is typically covered from day one even where routine dental waits.
• Switching insurer. Some insurers waive waiting periods already served on a comparable plan when you transfer; many do not. Ask before you switch, especially for maternity.

Waiting periods are the first thing to check on maternity cover and the second thing, after the limit, on dental.

How the four interact on a real claim

Take a single course of treatment and trace it through the limits. A physiotherapy course after surgery: the surgery is paid under inpatient up to the annual maximum; the physiotherapy sessions are paid under the outpatient benefit, subject to a session sub-limit and perhaps an outpatient amount; both count towards the annual maximum; and if the plan also has a lifetime limit on rehabilitation, the sessions draw that down too. If the surgery was dental, the routine dental waiting period decides whether anything is paid at all.

The order of operations is roughly: waiting period first, because if it has not run there is no claim; then the most specific sub-limit; then any aggregate it sits inside; then the annual maximum; then any lifetime limit. Cost sharing, the excess and co-insurance, applies on top, and the cost-sharing guide explains where in the order it falls.

Two consequences follow. First, the effective limit on any claim is the smallest figure in the chain, which is almost never the annual maximum. Second, a plan with an unlimited annual maximum is not unlimited for dental, therapy or maternity; it is unlimited for the admission, and limited for everything with a sub-limit.

Which limit to check for each benefit

Reading a plan this way is what IPMIBenefits means by comparing benefit by benefit. The benefits guide explains each line; Nomi shows the limits on every plan it quotes, next to the price.

Common mistakes with limits and waiting periods

• Comparing annual maximums and assuming the plan with the higher one pays more for everything.
• Missing that routine chronic care shares an aggregate with ordinary outpatient claims.
• Reading a per-pregnancy maternity limit as a per-year one, or the reverse.
• Adding a benefit at renewal and expecting the waiting period to have run from the original start date.
• Overlooking a lifetime limit on a policy you intend to keep for decades.
• Treating "paid in full" as unlimited when it is subject to the annual maximum and to usual and customary charges.

None of these is hidden. Every figure is in the table of benefits. The mistake is reading the first line and stopping.
