Yes, in three cases. From the age of 50, basic health insurance pays for a screening mammogram every two years in an early detection programme, without the deductible but with a 10 % retention fee. If you have an increased family risk or there is an urgent clinical suspicion, it pays at any age, with the deductible. It does not pay for screening outside a programme.

Key points at a glance
- Screening mammogram every two years from the age of 50, within a programme; no deductible is charged on this benefit (Art. 12e let. c KLV).
- The 10 % retention fee remains, because Art. 64 para. 6 let. d KVG only allows an exemption from the deductible.
- If you have a moderately or highly increased family risk of breast cancer, basic health insurance pays for digital mammography and breast MRI, adapted to risk and age, through a certified breast centre (Art. 12d para. 1 let. d KLV).
- For diagnosis, it pays for a mammogram if there is an urgent clinical suspicion of a breast disease (KLV Annex 1 no. 9.1).
What basic health insurance pays
A mammogram is an X-ray examination of the breast. For health insurance, what counts is the reason it is done. Early detection without symptoms is part of prevention: basic health insurance only pays for it if the Health Care Benefits Ordinance (KLV) lists it (Art. 26 of the Federal Health Insurance Act, KVG; Art. 12d and 12e KLV). Investigating a suspected condition is a benefit in the event of illness (Art. 25 KVG); the conditions for this are set out in Annex 1 KLV.
| Case | For whom | Frequency | Deductible | Legal basis |
|---|---|---|---|---|
| Screening mammogram in a programme | from the age of 50 | every two years | no, 10 % retention fee remains | Art. 12e let. c KLV |
| Monitoring at increased risk: digital mammography, breast MRI | moderately or highly increased family risk or comparable individual risk | adapted to risk and age according to the FOPH reference document | yes | Art. 12d para. 1 let. d KLV |
| Diagnostic mammogram | urgent clinical suspicion of a breast disease, any age | as decided by the physician | yes | Art. 25 KVG, KLV Annex 1 no. 9.1 |
| Screening without symptoms outside a programme | – | – | – | not a benefit of basic health insurance |
Art. 64 para. 6 let. d KVG allows screening to be exempt from the deductible: the Federal Council may exempt benefits from nationally or cantonally organised prevention programmes from the deductible. The provision does not mention the retention fee. You therefore pay 10 % of the invoice, up to the annual maximum of CHF 700 for adults (Art. 103 para. 2 of the Health Insurance Ordinance, KVV). In the other cases, the normal co-payment applies: first the deductible, then a 10 % retention fee (Art. 64 para. 2 KVG).
How the programme works
The requirements for an early detection programme are set out in the Ordinance on Quality Assurance in Programmes for the Early Detection of Breast Cancer by Mammography (SR 832.102.4). A programme is run in an area defined by one or more cantons, by an organisation recognised by one or more cantons (Art. 2 and 3). The organisation invites women aged 50 and over in writing and informs them about the risk of breast cancer and the meaning of the result (Art. 5). You are entitled to a consultation and information session, which you can waive in writing (Art. 5 para. 2, Art. 6). Each image is read by two independent specialists, and a third time if their results differ (Art. 8).
Monitoring at increased risk
Separate requirements apply to women with a moderately or highly increased family risk of breast cancer. The risk is classified with a risk calculation model; for the category “highly increased risk”, genetic counselling under Art. 12d para. 1 let. f KLV is required first. Before the first examination, there is a comprehensive, documented information and counselling session. A certified breast centre is responsible for the indication, counselling and monitoring; the imaging may also be done by service providers who work with such a centre under a contract. For a different centre, you need the insurer’s specific cost approval in advance. Whether monitoring is appropriate for you is something you decide with your physician.
What supplementary insurance pays
Screening outside the rules of the KLV, for example before 50 without a reason, more often than every two years or without a programme, is paid for at most by supplementary outpatient insurance. It is governed by the Insurance Contract Act (ICA); the law does not require it to contribute to preventive check-ups. Whether and how much a product pays, at what intervals and with which service providers, is set out in the insurer’s general terms and conditions.
No supplementary insurance may cover the deductible and retention fee of basic health insurance (Art. 64 para. 8 KVG); so you also pay the retention fee for screening in a programme yourself. We are building a comparison of supplementary products under Supplementary insurance. What counts is always the general terms and conditions and the information from your insurer.
Conditions
- Age and interval: Screening is covered from the age of 50, every two years. Basic health insurance does not cover earlier screening, even in the same two-year rhythm.
- Programme: Cover and the exemption from the deductible only apply within a programme under SR 832.102.4. The KLV does not say which cantons run a programme; your cantonal health department can tell you.
- Medical referral: Monitoring at increased risk and diagnostic mammograms are ordered by a physician (Art. 26 KVG, Annex 1 KLV).
- Breast centre and cost approval: Risk monitoring is done through a certified breast centre; for a different centre, you need the insurer’s cost approval (Art. 12d para. 1 let. d KLV).
- Deductible and retention fee: For screening in a programme, only the 10 % retention fee; otherwise the deductible and retention fee.
Sample calculation
Example with fictitious people and assumed costs. Three women have a mammogram in the same year, each assumed to cost CHF 200.00; the actual amount depends on the tariff. All three have a CHF 2,500 deductible and no other healthcare costs in the year. The deductible and retention fee follow Art. 64 KVG, Art. 103 KVV and Art. 12e KLV.
| Step | Esther, 56, screening in a programme | Ruth, 44, urgent suspicion | Karin, 47, no reason, no programme |
|---|---|---|---|
| Invoice (assumed) | CHF 200.00 | CHF 200.00 | CHF 200.00 |
| Covered by basic health insurance | CHF 200.00 | CHF 200.00 | CHF 0.00 |
| Deductible | does not apply | CHF 200.00 | – |
| Retention fee 10 % | CHF 20.00 | CHF 0.00 | – |
| Paid out by basic health insurance | CHF 180.00 | CHF 0.00 | CHF 0.00 |
| Own share | CHF 20.00 | CHF 200.00 | CHF 200.00 |
If you are examined regularly because of an increased risk, you bear these costs through the deductible. The deductible calculator works out the break-even point between a low and a high deductible, and the premium calculator shows the premiums for each deductible. A lower deductible must reach your insurer by 30 November, see Deadlines.
How to proceed
- Check for a programme: If you are 50 or older, ask your cantonal health department or your physician whether there is an early detection programme in your canton.
- Book within the interval: Note the date of your last screening mammogram; the next one is covered after two years. You can store invoices and statements of benefits in your account.
- Mention family risk: If breast or ovarian cancer occurs in your family, raise it with your physician; Art. 12d KLV applies to risk groups.
- Check the invoice: The statement of benefits for a screening mammogram in a programme must not show a deductible, only the retention fee.
Common mistakes
- Thinking screening is free. The deductible does not apply, but the 10 % retention fee does.
- Going for screening outside the programme. Without a programme and without a reason, basic health insurance does not pay.
- Not waiting long enough. Basic health insurance does not cover screening before two years have passed.
- Leaving symptoms until the next screening. Investigating an urgent suspicion is a separate, covered benefit; discuss any changes with your physician.

Frequently asked questions
Does health insurance cover a mammogram from age 50?
Yes, every two years, if the screening mammogram takes place within an early detection programme. The deductible does not apply; you pay the 10 % retention fee. Without a programme, basic health insurance does not pay for screening without symptoms.
Does health insurance pay for a mammogram before 50?
If there is an urgent clinical suspicion of a breast disease, yes, at any age, with the deductible and retention fee. The same applies if you have a moderately or highly increased family risk, through a certified breast centre. Screening without a reason before 50 is not a benefit of basic health insurance.
Is there an upper age limit?
Art. 12e let. c KLV does not set an upper age limit, only the start from the age of 50 and the two-year interval. Who is invited is decided by each programme; ask the programme directly.
What if my canton has no programme?
Then there is no screening without the deductible. In that case, basic health insurance only pays for a mammogram if there is an urgent clinical suspicion or an increased risk under Art. 12d KLV, each time with the deductible. Your cantonal health department can tell you whether your canton has a programme.
