If you're healthy and don't end up meeting your plan's out-of-pocket maximum—or even the deductible—having benefits that aren't subject to the deductible just means that your health insurance company will start paying for a portion of your care sooner than they would if all the services were subject to the deductible.

What applies to deductible?

A deductible is the amount you pay for most eligible medical services or medications before your health plan begins to share in the cost of covered services. ... Depending on how your plan works, what you pay in copays may count toward meeting your deductible.

What Does not subject to deductible mean?

Not subject to deductible: In deductible plans, some medical services are covered immediately and therefore are “not subject to deductible.” This means that from your first day of coverage, you can receive these services for the standard copayment or coinsurance, without having to first satisfy the deductible.
