What are the different types of health insurance available?

The main types of health insurance are HMOs, PPOs, EPOs, and POS plans. HMOs require you to choose a primary care physician and get referrals for specialists. PPOs offer more flexibility in choosing healthcare providers. EPOs are similar to PPOs but do not cover out-of-network care. POS plans combine features of HMOs and PPOs, allowing you to choose in-network or out-of-network care.
