Both HMO (Health Maintenance Organization) and PPO (Preferred Provider Organization) are types of Medicare Advantage Plans, but they have differences:

HMO: Typically, you need to choose a primary care doctor and get a referral to see a specialist. You are usually required to use doctors and providers in the plan's network, except for emergencies.

PPO: You don't need to choose a primary care doctor and don't require referrals to see specialists. You can use doctors in or out of your plan's network, but using the network will cost you less.

If your doctor doesn't accept Medicare, you may have to pay the full cost of the services provided. However, in some cases, doctors who don’t participate in Medicare may still choose to accept Medicare's approved amount for certain services, but they can charge you up to 15% over that amount (known as "excess charges").

If you have an HSA and enroll in Medicare, you can't contribute to your HSA anymore. However, you can still use the money in your HSA to pay for medical expenses, including Medicare premiums and out-of-pocket expenses.
