TRICARE Open Season is from Nov. 12 through Dec. 10, 2018. This is the annual period when you can enroll in or change your TRICARE Prime or TRICARE Select plan. Here is an overview of both plans. TRICARE Prime is a managed care option, similar to a health maintenance organization program. You will be assigned a provider who is your primary care manager (PCM). TRICARE Select is a self-managed, preferred provider option. You manage your own health care without a PCM and choose which TRICARE authorized providers you see. Compare TRICARE Prime and TRICARE Select using the Compare Plans tool.
