Maternity and fertility waiting periods compared across insurers

The comparison the brochures do not print

Maternity is the benefit where international insurers differ most and disclose least comparably. Each publishes its own waiting period, its own tier restriction and its own benefit categories, and none of them prints the others' figures next to its own. The result is that a decision with a lead time of well over a year is routinely made on the basis of a single insurer's marketing page.

What follows is the published position of the major carriers set side by side, with the client-supplied policy documents where those give a more precise answer than the marketing material. The existing guide to maternity cover in international health insurance covers what maternity benefits actually include, choosing a country of birth and the treatment side; this is deliberately the quantitative counterpart to it.

One figure is deliberately absent. AXA Global Healthcare offers routine pregnancy and childbirth from its Prestige level upward, but the waiting period attaching to it was not established in the research behind this guide. No figure is published here, and none should be inferred from the other insurers' twelve and eighteen months. Ask AXA directly.

Published waiting periods and tier restrictions

Two patterns run through the table. The first is that maternity is a tier benefit rather than a universal one — on every carrier in the set it appears only on the upper part of the range, which means the maternity decision is also a plan-level decision affecting everything else on the policy. Where the benefit sits inside a module rather than a tier, as it historically did on Allianz's legacy structure, the choice is narrower but the dependency question is sharper — see IPMI plan architecture: tiers versus modules. The second is that the waiting periods cluster at twelve and eighteen months, a six-month difference that decides whether a plan bought in January is useful for a birth eighteen months later.

Cigna publishes money limits at each tier as well as the waiting period, and the shape of them is instructive: the limit for complications of maternity is set at double the routine maternity limit on both Gold and Platinum, and the Platinum limits are double the Gold ones. Whatever else varies, the ratio between routine and complications is deliberate.

What a waiting period actually does

A waiting period is not an administrative delay before the policy takes effect. The policy is in force from the date of entry; the maternity benefit alone is unavailable until the stated period has elapsed from that date of entry.

Three consequences follow, and all three are commonly missed.

It runs from date of entry, not from the start of the current policy year, and not from the date a maternity module was added if that was later. Renewal does not advance it and does not reset it, but a lapse in cover generally does — insurers requiring continuous cover for the benefit will treat a gap as breaking it.

Because it runs from date of entry, the decision has to be made well over a year before the benefit is needed. On an eighteen-month wait, cover bought today first supports a birth roughly two years and three months from now once gestation is added. Anyone who buys maternity cover on discovering a pregnancy has bought it for a subsequent pregnancy.

And switching insurer restarts it. This is the specific, expensive and slightly counter-intuitive point: continuity arrangements that carry across underwriting exclusions do not necessarily carry a benefit waiting period across with them. Someone planning a family who moves insurer to save on premium can lose a year of served waiting period in the process. If you are within two years of wanting the benefit, that is a concrete reason not to move — and it is worth reading against the wider position in switching IPMI insurer without losing continuity.

Three benefit categories, and why the boundary matters at claim time

Allianz names three separate maternity categories: routine maternity, complications of pregnancy and complications of childbirth. Most of the market uses the same three, whether or not it labels them so clearly, and the boundaries between them decide which limit a claim is paid from.

The distinction is not academic. Complications limits are typically higher than routine limits, so a claim classified as a complication may be paid where the same cost classified as routine would exhaust the benefit. Cigna's published position illustrates the direction of travel: a Caesarean section is paid at the routine maternity limit unless it is medically necessary, at which point it moves into the complications category and the higher limit applies.

Complications benefits are also usually closed lists rather than general provisions. William Russell's complications of pregnancy benefit is limited to a named set — ectopic pregnancy, gestational diabetes, pre-eclampsia, miscarriage, threatened miscarriage, stillbirth and molar pregnancy — with childbirth itself expressly outside it. A closed list is easy to check before you buy and impossible to argue with afterwards.

The practical instruction is to read the complications definition before the routine limit, because that is where the large and unpredictable claims sit.

Cover on lower tiers: complications without maternity

The most useful thing on a plan without maternity is often that it still covers something.

William Russell's product information document, version 1 dated 10 November 2025, shows routine maternity care, care of newborns, Caesarean section, complications of childbirth and complications of pregnancy affecting the mother on Gold only, while listing limited cover for complications of pregnancy affecting the mother on Bronze and Silver. A member on a lower tier is therefore not covered for a delivery but may be covered for a defined set of conditions affecting the mother during pregnancy.

That is the right way round from an insurance perspective — the unpredictable, potentially serious event is covered and the planned, budgetable one is not — but it is not what most buyers assume they have. Anyone on a mid-tier plan should establish which of the three categories they hold, at what limit, and with what waiting period, rather than concluding from the absence of a maternity line that pregnancy is uninsured entirely.

Fertility: the sharpest divergence in the market

Fertility treatment is where the published positions diverge most, and where an assumption is most likely to be wrong.

Bupa Global includes assisted fertility within its Global Health Plans, subject to an 18-month waiting period — the same clock as maternity. Cigna includes infertility treatment within its International Outpatient module, which means it depends on that optional module having been purchased; the core International Medical Insurance plan alone does not carry it. William Russell excludes infertility, IVF and assisted reproduction outright, listed among the general exclusions in its product information document.

Surrogacy is commonly excluded across the market, including by Cigna. Where a pregnancy has been established through assisted reproduction, insurers frequently apply additional conditions even when the fertility treatment itself was funded elsewhere: William Russell's agreement gives no cover for complications of pregnancy until after the standard twelve-week scan where the pregnancy was established through assisted reproduction, irrespective of how long the policy has been in force, and restricts treatment of a newborn conceived by assisted reproduction and born within 36 weeks of conception to the complications-of-childbirth benefit.

The pattern is that fertility is treated as a discrete underwriting risk rather than as part of maternity, and it is priced, timed and excluded separately. Whether it is inside the core plan or inside an optional module also determines whether it can be added later — see core cover versus optional modules.

Adding the newborn, and the risk of leaving it late

The last window in the sequence is the shortest.

William Russell adds a newborn without medical underwriting and backdates cover to the date of birth, provided the name and date of birth are notified and the additional premium paid within 30 days of birth, and the policyholder has been insured continuously for 12 months or more at the date of birth. Its congenital and hereditary conditions benefit for newborns requires the baby to be added within 30 days, on the same plan, with either parent insured on one of the upper plans for at least 12 months before the birth.

AXA works the same risk from the plan-start side: where a baby is added within 10 months of the plan start date, AXA requests the baby's medical history and may apply pre-existing condition limits, with no cover for a special care baby unit or paediatric intensive care immediately after birth in that scenario. Allianz gives limited in-patient cover for multiple births and adopted babies in the first three months.

The site's existing modular IPMI plans guide covers how these components are assembled at the point of sale. Missing any of these windows converts an automatic, unwritten addition into a fresh underwritten application on a newborn — which is the one applicant whose medical history is entirely unknown and therefore priced conservatively. The wider mechanics of adding people to a policy are in family and dependant cover.

What to establish, and in what order

Work backwards from the date you want the benefit available. Subtract the waiting period, then check that against your existing date of entry rather than your renewal date — that gives you the real deadline.

Then confirm four things in writing: which plan tier carries routine maternity and whether you hold it; whether complications of pregnancy and complications of childbirth are separate benefits with separate limits, and whether the complications list is closed; whether fertility treatment is in the core plan, in a module, or excluded; and what the newborn notification window is and what prior-cover condition attaches to it.

Finally, if any part of that analysis makes a different insurer look better, price the cost of restarting the waiting period before you move. The limits are set out in the plan's benefit table; how those tables are constructed, and where the inner limits sit, is covered in annual benefit limits and inner limits.
