Identify the law and the reason first
The Federal Office of Public Health distinguishes voluntary daily allowance insurance under the Health Insurance Act from private cover under the Insurance Contract Act. Identify which law your policy cites before deciding how to respond. Ask the insurer to explain precisely why it reduced or refused the benefit and which dates are affected. It may be about the waiting period, the degree of incapacity, an exclusion, a missing document or disagreement about insured earnings. Each issue calls for different evidence.
Rebuild the calculation one line at a time
Assume the policy would pay CHF 150 per day at the full benefit rate. You expected 20 payable days and received CHF 1,800 rather than CHF 3,000. That amount could represent 12 days at CHF 150, but it could also represent 20 days at CHF 90. Ask for the number of days used, the amount per day and the contract term behind the calculation. There is little value in arguing over the daily rate if the real difference is the number of days accepted.
Match your evidence to the issue
If the disagreement is about dates, gather the certificates and any proof the insurer received them. If it concerns self-employed earnings, prepare the evidence your policy calls for and match it to the accounting periods in question. Ask for the insurer’s secure channel for any medical documents. Start with a short timeline and the clauses the insurer cited. Ask for written acknowledgement and find out when you should expect a response.
Mediation and a formal challenge serve different purposes
For a private contract, FINMA explains that the courts decide individual disputes and points to the appropriate mediation service, depending on the insurer. A report to the regulator does not amount to a formal appeal. For social insurance, ask what formal decision and challenge process apply. Check the relevant time limits promptly, especially if you seek mediation. Do not assume that informal discussions stop a deadline running.
Build an interim cash plan while the claim is disputed
In the example, the CHF 1,200 difference is unavailable until the claim is resolved. Work out which essentials you can pay with confirmed money, including household rent, your business lease and other unavoidable costs. If your arrangements distinguish personal income and business expenses, maintain separate budgets. This gives you a way to protect essential payments while the insurer or an independent adviser reviews the figures.
