High-deductible plans: how to control what you actually pay

You should pay the negotiated rate, not the list price

Even before your deductible is met, an in-network provider is contractually limited to the plan's allowed amount. If the provider bills you the gross charge, they are billing above contract. The EOB's 'you may owe' figure is the number that governs.

Wait for the EOB before paying anything. Paying a provider statement that arrives ahead of the EOB is the single most common way people overpay on an HDHP.

Preventive care should be $0

Most plans must cover a defined list of preventive services with no cost sharing, even before the deductible. When a preventive visit generates a bill, the cause is usually a diagnostic code attached to a screening service.

Ask the provider to review the coding. A screening colonoscopy that becomes diagnostic because a polyp was removed is a well-known case where coding rules — and often your plan's own policy — decide whether you owe anything.

Use the HSA deliberately

HSA dollars are pre-tax going in, tax-free coming out for qualified expenses, and there is no deadline to reimburse yourself. Keep every receipt and EOB; you can pay out of pocket now and reimburse from the HSA years later once the balance has grown.

• Keep receipts and EOBs together, per date of service
• Never reimburse from the HSA until the EOB confirms the amount
• Track reimbursements so you never double-claim an expense

Timing and shopping

Deductibles reset annually. If you have already met yours, elective care completed before the reset costs less. If you have not, comparing published cash prices to your negotiated rate is worth doing — for some imaging and lab work the cash price is lower than the deductible-phase rate.
