There are multiple options to have an insurance provider cover some or all of your costs not covered by original Medicare. These plans allow you to keep Medicare as your primary coverage and have varying premiums and deductables.
An insurance provider becomes your primary coverage, but agrees to cap your maximum out of pocket for the year. These plans are either PPO or HMO plans with a network of doctors and typically include drug coverage.
Standalone drug plans are required if you do not have any other creditable prescription coverage such as; an employer plan or coverage included in an Advantage plan. Failure to have creditable coverage can lead to financial penalties.
