Amount: Deductibles are specified in the insurance plan's terms and conditions and are typically expressed as an annual dollar amount. For example, a health insurance plan might have a $1,000 deductible per year.

Paid by Insured: The insured individual is responsible for paying the deductible amount directly to healthcare providers or for covered services or expenses out-of-pocket before the insurance company begins to contribute.

Accumulation Period: Deductibles usually apply on an annual basis, meaning that they reset at the beginning of each plan year (often on January 1st). Once the deductible is met for the year, the insured individual typically does not need to pay it again until the start of the next plan year.

Covered Services: Deductibles typically apply to certain covered services or medical expenses, such as doctor visits, hospital stays, prescription drugs, laboratory tests, and other healthcare services specified in the insurance plan. However, some services, such as preventive care (e.g., annual check-ups, vaccinations, screenings), may be exempt from the deductible and covered at 100% by the insurance plan.

Coinsurance and Copayments: After the deductible is met, the insurance plan may require the insured individual to pay coinsurance or copayments for covered services, in addition to any deductible already paid. Coinsurance is a percentage of the cost of the service that the insured individual is responsible for paying, while copayments are fixed amounts paid for each service.

Different for In-Network and Out-of-Network: Deductibles may vary depending on whether the healthcare provider is in-network (participating in the insurance plan's network) or out-of-network (not participating). Deductibles are often higher for out-of-network providers.

Exclusions: Some healthcare services or expenses may not count toward the deductible, such as cosmetic procedures, elective surgeries, alternative therapies, or services that are not covered by the insurance plan.
