Cash price Discounted cash price What a hospital charges a self-pay patient who pays directly, without going through insurance — usually well below the gross charge. Example: A CT scan has a $3,200 gross charge but an $850 discounted cash price. Ask for it by name when scheduling — hospitals don't always advertise it up front.

What you pay up front if you don't use insurance.
$643.00
Gross charge Gross charge (chargemaster price) The hospital's full, undiscounted list price — pulled from its internal "chargemaster" price list. Almost no one actually pays this. Example: A chest X-ray has a gross charge of $1,450. The same hospital's discounted cash price for the same X-ray is $180 — the gross charge mostly anchors negotiations, not what patients pay.

Negotiated rates by payer
?
Negotiated rate
The price a specific insurance plan agreed to pay the hospital for a service — it varies by insurer, and even by plan within the same insurer.
Example: The same knee MRI has a negotiated rate of $904 with one insurer's PPO plan and $1,509 with another's — identical hospital, identical scan.

Full explanation →Payer ?Payer The insurance company footing the bill — Aetna, UnitedHealthcare, Medicare, and so on. Example: "Blue Cross Blue Shield" is the payer. Its negotiated rate for an MRI might be $904, while a different payer's negotiated rate for the same scan is $1,509. Full explanation → |
Plan ?Plan The specific product an insurer sells — e.g. "Blue Cross PPO 500" — which sets your deductible, coinsurance and negotiated rates. Example: Two people both insured by Aetna can owe very different amounts for the same MRI: $50 with an HMO plan's flat copay, or the full $1,200 toward a high-deductible PPO plan's unmet deductible.
