Supplemental plans
The right top-up for your GKV.
An overview of the most important private supplemental policies that cover gaps in statutory health insurance.
Why a supplemental plan?
GKV is mandatory coverage with clear limits: it pays only 60–75 % of standard dental prosthetics, sick pay caps at 70 % of net income (about €120/day), it reimburses nothing outside Europe, and a single hospital room is out-of-pocket only. A supplemental policy fills exactly these gaps — surgically, without forcing you to change your whole insurance setup. Households typically spend €250–800 a year on supplemental cover, far less than a single uninsured incident would cost.
An important clarification: a supplemental plan is NOT a substitute for the GKV but built on top of it. You keep your GKV status, family coverage and switching rights — and only top up specific risk areas. Unlike a full PKV switch, supplemental policies can be cancelled at any time (usually 1–3 months’ notice), allow adjustments at life events and don’t exclude you from the solidarity system. Anyone reacting to rising GKV rates with a frustrated full switch usually does better with targeted supplemental policies.
Actuarially, supplemental policies make sense most for plannable and expensive events: dental prosthetics (implant €2,500–4,000 per tooth), hospital stay with comfort wishes (single room €80–200 extra per day), treatment abroad (US daily rates €3,000–10,000). Here the potential damage exceeds the premium many times over — the classic definition of useful insurance. For small recurring costs like glasses, insurance often doesn’t pay; a self-funded reserve is more economical.
Dental supplement: the most-bought policy
With over 17 million contracts, dental supplemental insurance is the most common private supplemental policy in Germany — and for good reason: GKV reimburses only the fixed subsidy for the standard solution (60–75 % of a basic option), while a good supplement covers 80–100 % of the actual bill — including all-ceramic, implants, inlays, root canals and professional cleaning. For a typical implant case at €3,500, GKV pays around €700 and the supplement the remaining €2,800 — a €25/month premium pays for itself many times over after a single claim.
Important selection criteria are the waiting period (3–8 months standard), benefit caps in the first 3–5 years (typical €1,000–3,000 cumulative), reimbursement rate for prosthetics, and inclusion of professional cleaning. Premium tariffs additionally waive the offset against the GKV subsidy, lowering your out-of-pocket cost further. The policy must be taken out before the first treatment plan — already announced treatment is never reimbursed, even after the waiting period.
A useful rule: the younger you are, the better the conditions. At 25 a top tariff costs around €18/month; at 50 often double for the same benefits. Children also benefit strongly — orthodontics from indication grade KIG 1–2 (about 60 % of all malocclusions) is not covered by GKV but by a good supplement. For families an early purchase is triple-helpful: lower premiums, longer claim-free intervals and protection for predictable orthodontic cases.
Travel health: a must for travelling
Travel health insurance is by far the cheapest supplemental policy — and one of the most important. GKV doesn’t cover treatment outside the EU/EEA (plus Switzerland) at all, and even within the EHIC zone there is no medical repatriation to Germany. A US hospital day costs €3,000–10,000, a medical evacuation flight quickly €30,000–80,000. An annual policy for a single person costs €8–15, for a family €25–40 a year. The premium-to-risk ratio is exceptionally favourable — few other insurance products match it.
Four standard benefits matter: "medically reasonable" (not just "medically necessary") repatriation, full outpatient and inpatient cover with no sublimits, emergency dental pain treatment up to at least €300, and direct billing between insurer and hospital (you don’t want to pay €5,000 cash on the spot). A 24-hour emergency hotline in German is also a practical advantage that takes a lot of stress out of medical emergencies.
Frequent travellers are nearly always better off with the annual policy, which covers unlimited trips up to 6–8 weeks each. Anyone who travels only once a year may opt for a per-trip policy at €1–2 per day — from three trips a year onward the annual policy wins. Longer stays (semester abroad, sabbatical, multi-month backpacking) need a separate "long-term" tariff with its own conditions, since the standard maximum trip length applies.
Sick pay for the self-employed
The self-employed in GKV have only limited entitlement to sick pay — and only if they choose the higher general rate of 14.6 % rather than the reduced 14.0 %. Statutory sick pay then equals 70 % of net income (max around €120/day) and starts on the 43rd day of illness. A sick-pay supplemental policy fills the gap: it usually pays from day 22 of illness (sometimes earlier) a contracted daily benefit that maintains your standard of living. On a €4,000 monthly income a €100 daily benefit from day 22 costs about €35–55/month.
The right benefit level is based on net — not gross — income. Customary is 80–90 % of average daily net; higher is not allowed (no enrichment). The self-employed should be able to provide tax assessments or income statements when applying, since the insurer verifies the level in case of claim. A sick-pay policy is also useful for voluntary GKV members who chose the reduced rate without sick pay — they would otherwise have no income protection during longer illness.
An important special rule: the sick-pay policy is tied to professional activity in case of claim. Anyone unable to perform their self-employed activity for more than 6 months counts as "occupationally disabled" — the sick-pay policy ends, and disability insurance (BU) should kick in. A sick-pay supplement therefore never replaces a BU; it is an additional cushion for temporary illness. Both modules together are practically essential for self-employed with families.
Inpatient supplement: senior doctor and single room
Inpatient supplemental insurance covers three main hospital benefits: senior-doctor treatment (instead of ward doctor), single or twin room (instead of multi-bed), and free choice of hospital in Germany. It typically costs €15–50/month, depending on entry age and benefit scope. For young, healthy insured it’s cheap and cannot be added later without underwriting — anyone signing up at 30 secures conditions they will not get at 60. The policy applies to every planned and acute hospital stay, often also to rehabilitation.
Practically the policy makes a difference in two areas. First in comfort — a single room with private bathroom is bookable in modern clinics for an extra €80–200 per day. Over a longer stay (operation plus rehab) that quickly adds up to €2,000–5,000 per claim. Second in choice of doctor: with senior-doctor cover you can be operated on by the chief physician, which for complex procedures measurably improves outcomes. Standard patients without supplemental cover see ward doctors on rotating shifts — usually medically adequate, but without choice.
Combining with hospital daily allowance is wise: while the supplemental policy covers direct treatment costs, the daily allowance pays a fixed sum per hospital day (e.g. €30/day) you can use for phone, accompanying person, lost income or deductibles. Both modules together cost €25–60/month and protect financially in serious hospital cases. Some insurers offer combo tariffs at 10–15 % discount over individual cover.
Outpatient and care supplements
Outpatient supplemental insurance covers gaps in everyday practice: alternative practitioner treatment (GKV: zero, policy: €800–1,500/year), eyeglasses for adults (GKV: zero, policy: €200–500 every two years), extended preventive exams, travel vaccinations and sometimes osteopathy. It costs €10–25/month and is especially useful for those regularly using alternative methods. The long-term care supplemental insurance (Pflege-Bahr) is state-subsidised at €60/year and pays a daily care allowance on top of statutory care insurance — important since GKV care benefits often cover only 30–60 % of actual costs.
For long-term care insurance there are three variants: care-cost insurance (reimburses specific bills up to a contracted limit), care daily-allowance (pays a fixed sum independent of actual costs), and care annuity (pays a monthly annuity in case of care). For most insured the care daily-allowance is the most flexible — usable freely, plannable, and not tied to receipts. The state-subsidised Pflege-Bahr tariff is a cheap entry but often covers only a fraction of actual need.
Important to know: care supplemental premiums rise sharply with age. Anyone signing up at 35 pays around €30/month for €1,500/month daily benefit at care level 5 — at 55 already €70–90/month. Past 70 the policy is often no longer offered or only at substantial risk surcharges. The policy is therefore a typical "young investment for the future" — financially hard to justify but potentially life-saving for the family that would otherwise bear the personal share (averaging €2,500/month in 2026).
When is it worth buying?
Three rules of thumb. First, before the need, not after — once your dentist has issued a treatment plan, no insurer will pay for it anymore. Second, young rather than late: at 30 you often pay half what a 50-year-old does for the same coverage, and the 3–8 month waiting periods are long over by the time you actually need them. Third, targeted rather than complete: one well-chosen module almost always beats an expensive all-in-one bundle on price-to-value. Always compare at least three providers and watch for benefit caps in the first few years.
The ideal timing depends on the type of insurance. Travel health should be in place before any trip abroad, ideally as an annual policy from year one. Dental supplement is most worthwhile for young adults (20–35) before initial damage appears. Inpatient and care supplements are cheap when young and become expensive or unobtainable later. Sick-pay is relevant from the start of self-employment. A complete overview by life phase with recommended modules is on our detail pages for each insurance type.
Avoid these three anti-patterns: First "buy when sick" — most policies refuse to cover existing treatments. Second "as cheap as possible" — the cheapest tariff often has the worst conditions, high deductibles and low maximums. Third "as much as possible" — an all-in-one policy at €60–100/month includes benefits you’ll likely never use. Better: targeted purchase of 2–3 fitting individual policies for the truly relevant risks of your situation.
Comparison and tips
Practical procedure for a sensible choice: 1. Clarify your risk inventory — what life situation, what age, which benefits did you actually use in recent years? 2. Prioritise gaps — typically dental before travel before inpatient. 3. Compare at least three providers — Stiftung Warentest, Finanztip, independent insurance brokers. 4. Read the contract terms, especially waiting periods, benefit caps and cancellation rules. 5. Check lifetime premium development — some tariffs already rise 30–50 % after 10 years.
A frequently overlooked strategy: some health funds offer their members discounted supplemental tariffs with top insurers — so-called group contracts. The premiums there are 10–25 % cheaper than the open market, with identical benefits. Anyone using a top fund with strong cooperation partners should always check if a group rate exists before signing direct. These discounts are rarely highlighted in advertising but are widely available.
When designing a contract, look for flexibility: ideally you have a switching right to other tariffs of the same insurer without renewed underwriting, a premium pause option (e.g. for parental leave or stays abroad), and the right to cancel monthly without minimum term. These options are not a given — some tariffs effectively bind you for life because a later switch with new health questions becomes impossible. Read at least the "cancellation" and "tariff change" sections carefully before signing.
