Abstract: This paper sheds light on some unexpected consequences of health insurance regulation that may pose a big challenge to insurers' risk management. Because mandated uniform contributions to health insurance trigger risk-selection efforts, risk adjustment (RA) schemes become necessary. A good deal of research into the optimal RA formula has been performed. A recent proposal in Switzerland has been to add 'Hospitalization exceeding three days during the previous year' as an indicator of high risk. Applying the new formula to an individual Swiss health insurer, its payments into the RA scheme are predicted to increase substantially, reaching up to 13% of premium income. Its mistake had been to implement Managed Care successfully, resulting in low rates of hospitalization. The expected risk management response is to extend hospital stays beyond three days, contrary to stated policy objectives.
