Final answer:
A PPO has more choices of specialized health care providers compared to an HMO.
Step-by-step explanation:
An advantage of a Preferred Provider Organization (PPO) compared to a Health Maintenance Organization (HMO) is that there are more choices of specialized health care providers.
In a PPO, you can see any doctor or specialist you choose without needing a referral.
This gives you greater flexibility and access to specialized care if needed.
