Kindernachversicherung: Insuring a Newborn in PKV (2026)

How do you add a newborn to private health insurance in Germany?

You file a Kindernachversicherung (newborn enrolment) application with the parent's own insurer within two months of the birth. The insurer is then obliged[1] to insure the child with no risk surcharges and no waiting periods, and cover runs from the completion of the birth, so there is no gap even if the form arrives in week seven.

This is one of the genuinely strong features of the private system, and it is easy to underrate until you need it. Ordinarily, joining private cover means a health assessment and whatever the insurer concludes from it. Here the insurer has no say: it cannot ask health questions, cannot price in a risk surcharge, cannot exclude a condition, and cannot apply the waiting periods that would normally delay dental work, orthodontics or psychotherapy.

The catch is entirely in the timing.

What are the three conditions for Kindernachversicherung?

Three things must hold: a parent is insured with that insurer on the day of the birth and has been for long enough under the contract, the application reaches the insurer within two months of the birth, and the child's cover is no better than the parent's. All three come from the same provision.[1]

In detail:

1. A parent is insured with that insurer on the day of the birth. The contract may additionally require a minimum period of prior cover, and this is where nearly every competitor page goes subtly wrong. The provision only requires that cover exists[1] on the birth date. It is Abs. 3 that permits the insurer to agree a minimum prior-insurance period, and it caps that period at three months. The standard policy terms use the full three months, so in practice that is what most contracts say, but it is a contractual ceiling rather than a statutory floor. If your policy is only a few weeks old when the baby arrives, read your actual terms rather than assuming. The three months count backwards from the birth date, not from when you apply.
2. The application reaches the insurer within two months of the birth, with retroactive effect. Cover then starts at completion of the birth.
3. The child's cover is no higher and no more comprehensive than the insured parent's. You cannot use the guarantee to place the baby in a premium tariff while the parent sits in a mid-tier one. Where the two parents hold different tariffs, this is a real planning lever: register the child under whichever parent has the cover you want for the child, provided that parent also clears the prior-insurance rule.

What happens if you miss the two-month deadline?

The guarantee disappears. Two months is an Ausschlussfrist, a cut-off that extinguishes the right itself rather than merely pausing it, so there is no late filing, no extension and no good-cause exception. The child then needs an ordinary private application, with full health questions answered at its current state of health.

At that point the insurer regains all its normal options: accept at standard terms, accept with a risk surcharge, accept with a permanent exclusion for a specific condition, or decline.

For a healthy baby, missing the window is usually an administrative annoyance that ends in ordinary acceptance. For a baby with a condition diagnosed at or shortly after the birth, it is a different matter entirely, because anything on record by the application date is a pre-existing condition. The realistic outcomes are a permanent exclusion of that indication, a substantial surcharge, or refusal. The remaining route is then the Basistarif, which insurers must offer without surcharges or exclusions, but at benefits comparable to the public system rather than to your own tariff.

There is one more consequence that surprises people, and it is the strongest reason to treat the date seriously. If both parents are privately insured, there is no public fallback. A newborn cannot independently qualify for voluntary statutory membership, because it cannot meet the statutory pre-insurance requirement,[2] and there is no publicly insured parent to co-insure it under family cover. The instinct to say "we will just put the baby in the public system instead" does not work in a two-PKV household.

Are congenital conditions covered?

In practice yes, and for a newborn enrolled within the window the insurer cannot exclude anything. The wording still varies: many tariffs state expressly that congenital conditions of the newborn are covered, while a minority leave it implicit, relying on the argument that cover begins at completion of the birth, so no condition pre-exists it.

That reasoning is defensible. The problem is where it leaves you if it is ever contested: arguing about the interpretation of policy terms at exactly the moment you have a sick baby.

So treat it as a question to settle in advance. Ask your insurer to confirm in writing how your specific tariff handles congenital conditions, and do it before the birth rather than after. A written answer costs you one email during the pregnancy and removes the only real ambiguity in an otherwise very solid guarantee.

What if one parent is in public insurance instead?

Then the child can normally be co-insured free,[3] with no premium, no health check, and no application deadline. The entitlement arises by operation of law once the conditions are met; registering with the Krankenkasse is administrative, and it takes effect from the birth.

The registration is not urgent in the way the private one is, but do it promptly anyway, since it is what gets the child's insurance card issued. There is a general income limit of €565 per month for a co-insured person in 2026, which is irrelevant for a newborn but becomes relevant much later.

Mixed households have one exception, and marital status decides whether it applies at all:

• Unmarried parents: the exception does not apply. The child goes on the publicly insured parent's family cover regardless of who earns more.
• Married parents or registered partners: the child is excluded from free family cover only if all three hold true: the privately insured parent is not a member of a Krankenkasse, their regular total income exceeds €6,450 per month in 2026 (one twelfth of the JAEG), and that income is regularly higher than the publicly insured parent's. Miss any one of the three and the free cover survives.

Note the threshold is the JAEG, not the contribution ceiling. Using the wrong one is a common error in expat-facing content. Family health insurance in Germany works through the household maths in full.

There is a timing quirk here that catches out exactly the households this post is written for, and it is worth understanding before you make a decision on it. Take a married couple where the mother is privately insured, earns above the JAEG and out-earns her publicly insured husband. On those figures the child is excluded from free family cover. But during her Elternzeit she has no regular income above the threshold, because parental allowance is not counted as income for this test. The exclusion condition therefore fails while she is on leave, and the newborn can go on the father's family cover for that period.

That is a real saving, and it is also a trap. The window closes when she goes back to work on her old salary, because the three conditions apply again and the child drops out of free cover. By then the two-month private enrolment window is long gone, so the child would need an ordinary application with full health questions. If you use the parental-leave window, treat it as a temporary saving rather than the plan, and decide before the two months run out whether you also want the private enrolment as the durable answer.

How does adoption work?

The same way, with one difference. The same provision puts adoption on the same footing[4] as birth, provided the child is still a minor at the time of the adoption, so it is not limited to infants. The prior-insurance rule and the two-month window apply exactly as they do for a birth, counted from the adoption instead.

The difference sits in the pricing. Where a higher risk exists, for instance a documented pre-existing condition, the insurer may agree a risk surcharge of up to one full premium, meaning the premium may at most double. For a biological newborn, surcharges are excluded outright. In practice, acceptance at standard terms is the norm and that surcharge headroom is reserved for genuine special cases.

Documents are the same, with adoption papers in place of the birth certificate.

What does PKV cost for a child, and which tariff should you pick?

Expect roughly €150 to €250 per month for a child's own contract in 2026, as a broad market range rather than a quote. What moves the figure is mainly the level of cover you choose. Within the children's rate the premium does not follow the child's age, but there are age steps: many insurers move to a teenage rate before 18 and to the adult rate at 21, and the ages differ between insurers, so the tariff's own terms are what to check. The statutory 10 % surcharge that adults carry is not levied until the calendar year after the insured turns 21, so it is not in a child's premium at all.

Two things reduce the real cost more than parents expect.

Private long-term care cover for children is free. The child needs its own comprehensive health contract with its own premium, but the private long-term care insurance covers the policyholder's children at no additional premium.[5] Readers arriving from the public system usually assume private means paying per person for everything. That is only half true.

The employer subsidy stretches further than one contract. The employer subsidy is half of what the employee pays for health insurance, capped at €613.22 per month outside Sachsen in 2026 (€584.15 in Sachsen, where the employer's care-insurance share is lower). Because co-insured children count toward the total the subsidy is calculated on, any headroom left on the parent's own contract can absorb part of the child's premium. Where the parent's premium does not already exhaust the cap, adding a child costs materially less net than the sticker price suggests.

For tariff choice, four things actually matter:

1. The parent's tariff is the ceiling, so if both parents are privately insured, choose which one to register under deliberately.
2. The deductible is the biggest single lever on the premium. Judge the Selbstbeteiligung carefully for a young child, who will be at the doctor often in the early years.
3. Check outpatient cover, the preventive check-up catalogue and orthodontics. Orthodontics arrives about ten years later but is priced into the tariff now, and the public system only funds the more severe grades, capped at age 18, with a 20 % own share that is refunded once the treatment is completed as planned,[6] and set at 10 % from the second child under 18 being treated at the same time.[6]
4. Later changes are possible but not free. Switching tariff within the same insurer stays open[7], though moving up into materially better cover can trigger underwriting for the added benefits.

Children of civil servants are the cheapest configuration in the market: where the child qualifies for Beihilfe at 80 %, only a 20 % top-up tariff is needed. See the Beamte glossary entry for how that entitlement works.

One last thing worth knowing, because it uses the same logic: if the privately insured parent dies, the co-insured child normally has a right to continue as its own policyholder without new underwriting, and that right is also commonly bound to a two-month window.

A child enrolled through this route carries that acceptance for life. The insurer never revisits the underwriting, so a condition that develops at age six or sixteen cannot be excluded or surcharged afterwards. It is a strong guarantee, and the whole of it depends on one date.
