Implement the No Surprises Act balance billing protections for out-of-network emergency services: detect applicable claims and apply the correct payment calculation
Identify claims that meet the definition of a covered emergency service rendered by a nonparticipating provider at an in-network emergency facility — these claims fall under the No Surprises Act balance billing prohibition.
Calculate the qualifying payment amount (QPA) for each claim: the QPA is generally the plan's median contracted rate for the same or similar service in the same geographic area, determined as of January 31, 2019, and indexed annually.
Apply the greater of three potential payment floor options as required: the QPA, the plan's usual out-of-network amount, or the amount that would be paid under Medicare fee-for-service — this ensures the patient is not balance billed beyond cost-sharing based on the applicable floor.
Notify the provider of the initial payment or denial with an explanation, informing them of the QPA and their right to initiate open negotiation within 30 business days.
Send the patient an Explanation of Benefits that reflects the cost-sharing based on in-network rates (not out-of-network rates), with a notice that balance billing above the cost-sharing amount is prohibited for this service.
Maintain documentation of the QPA calculation methodology and data source for each service type and geographic area in the event of an IDR challenge.
Known gotchas
The QPA calculation methodology has been subject to ongoing rulemaking and court challenges; confirm that you are using the currently operative QPA rules, as earlier court decisions vacated portions of prior regulations.
Air ambulance services rendered by nonparticipating providers are also covered by the No Surprises Act balance billing protections but use a separate QPA calculation pathway — do not apply the ground emergency QPA to air ambulance claims.
Cost-sharing for covered NSA services must be calculated based on the in-network cost-sharing level, not the out-of-network level; applying out-of-network deductibles and coinsurance to these claims is a common error that exposes the plan to patient complaints and regulatory penalties.
