A type of managed care organization. In return for a monthly premium, plus any applicable deductible or co-payment, all or most of an individual's physician services will be provided by the HCPP. The HCPP will pay for all services it has arranged for (and any emergency services) whether provided by its own physicians or its contracted network of physicians. If a member enrolled in an HCPP chooses to receive services that have not been arranged for by the HCPP, he/she is liable for any applicable Medicare deductible and/or coinsurance amounts, and any balance would be paid by the regional Medicare carrier.
