APO stands for Army or Air Force Post Office. The same is true as above, however they ocassionally service Navy and Marine personnel.
The HMO will not pay for non-emergency care provided by a non-HMO physician. Additionally, there may be a strict definition of what constitutes an emergency. Like an HMO, a preferred provider organization (PPO) is a managed healthcare system. However, there are several important differences between HMOs and PPOs. A PPO is actually a group of doctors and/or hospitals that provides medical service only to a specific group or association.
