Question

What is a main difference between a HMO and a PPO? include references

Answer 1

The main difference between HMO and PPO is the claim difference where in HMO, the insuranc companies directly pays the health providers and therefore no patient is required to make a claim. But in a PPO, patients must actually pay them first and then make a claim about the reimbursement all in all.
