Since Patrick J. Geraghty arrived here a year and a half ago to lead the state's largest health insurer, Florida Blue, he has expanded its operations in Medicare and Medicaid, entered arrangements with hospitals and doctors, bought a medical group, and dabbled with a new private sector marketplace that allows employees to choose plans from different insurance companies.

After years of focusing on selling plans to employers, rather than individual consumers, the insurers must alter course.
