Final answer:
TRICARE Select costs can change annually, usually at the beginning of the fiscal year on October 1st, with adjustments based on healthcare inflation and policy changes.
Step-by-step explanation:
TRICARE Select costs may change annually. The Department of Defense adjusts the TRICARE Select costs, including enrollment fees, deductibles, and copayments, based on various factors such as healthcare cost inflation and policy changes.
These changes are often implemented at the beginning of the fiscal year on October 1st. Hence, beneficiaries should be prepared for potential adjustments to their healthcare expenses once a year. It's important for those utilizing TRICARE Select to review the published rates annually to budget for the upcoming year.
The costs associated with TRICARE Select for beneficiaries are determined by the Department of Defense (DoD) and can change on an annual basis.
For example, the DoD may adjust the premiums, deductibles, and copayments for TRICARE Select each year to reflect changes in healthcare costs.
Therefore answer is b) Annually.
