How the QPA Is Calculated
- The plan takes its contracted rates for the same or a similar service, from providers in the same or a similar specialty, in the same area and insurance market.
- It uses the rates in effect on January 31, 2019, and leaves out bonuses, risk-sharing and other incentive payments.
- It finds the median of those rates. The plan needs at least three contracted rates; if it has fewer, it uses other data.
- It raises that median each year by the change in the consumer price index (CPI-U).
What the QPA Is Used For
| Use | How it works |
|---|---|
| Patient cost sharing | For protected care, your coinsurance or deductible is figured on the lesser of the billed charge or the QPA, unless a state law or all-payer model sets the amount. |
| Payment disclosure | The plan must send the QPA with its first payment or denial for a protected out-of-network claim. |
| Payment disputes | If the provider and plan cannot agree, a certified independent dispute resolution (IDR) entity considers the QPA among other factors. |
Example
An out-of-network anesthesiologist bills $2,000 for care at an in-network hospital. The plan's QPA is $600, and you have already met your deductible, with 20% coinsurance. You owe 20% of $600, which is $120. The anesthesiologist cannot bill you for the rest.
For Billing Teams
- Check the QPA on the remittance for every protected out-of-network claim.
- Do not balance bill the patient above the in-network cost share.
- If the payment looks too low, you can negotiate with the plan and then use the federal IDR process.
- The federal IDR administrative fee is $15 per party for disputes started on or after June 11, 2026, down from $115.
