This article describes the behavior of insurance health companies registered during 2012 to 2016, from the state of Huila - Colombia. A retrospective observational descriptive study was performed; the source of information was a national database “Registro Único Comercial y Social - RUES”; taking into account only registered health insurance companies, their economic activity, size and location. It was found an inverse association between company size and survival, and a direct association between size and number of companies that are registered under a specific economic activity. This information can be useful for future projects, strategies, interventions for new and established health insurance companies.
