which of these types of health insurance plans requires a referral to see a specialist?\nepo\nppo\nhmo\nhsa
Answer
Brief Explanations:
HMO (Health - Maintenance Organization) plans typically require a referral from a primary - care physician to see a specialist. EPO (Exclusive Provider Organization) and PPO (Preferred Provider Organization) plans generally do not require referrals, and HSA (Health Savings Account) is a savings account for medical expenses, not an insurance plan type in the same sense.
Answer:
C. HMO
