Balance Billing, an OOP Max, and a Retrospective Denial
Priya holds a non-grandfathered bronze plan through Connect for Health Colorado: $7,500 deductible, 40% coinsurance after the deductible, $9,200 individual out-of-pocket maximum. She had an emergency appendectomy at an in-network hospital. The plan's allowed amount for the admission is $31,000. The emergency physician group and the radiologist who read her CT are out of network and have sent balance bills totaling $2,340. Separately, the plan completed a retrospective review and denied the inpatient stay as not medically necessary, asserting it should have been billed as observation; the denial would leave her owing an additional $6,800.
1. Assuming the claim is paid as billed, what is Priya's maximum liability, and what happens to the $2,340?

Plan liability math. Deductible $7,500, then 40% of the remaining $23,500 = $9,400. Total cost sharing would be $16,900, which exceeds the out-of-pocket maximum, so the OOP maximum controls: $9,200. The plan absorbs the difference.
The balance bills. Emergency services are protected under both Colorado's balance-billing statute and the federal No Surprises Act. The hospital is in network, and the emergency physicians and radiologist were not chosen by Priya. She may be billed only in-network cost sharing, and those amounts count toward her deductible and OOP maximum. The $2,340 should be zeroed out against the plan at in-network rates.
The notice-and-consent exception does not apply. An out-of-network provider at an in-network facility can bill the patient only if it gave at least 72 hours' advance written notice and obtained signed consent. Nobody obtains informed consent for a CT read from a patient being wheeled into an appendectomy, and emergency services are excluded from the exception outright.
2. Map the appeal route and the deadlines for the medical-necessity denial, and explain why this is not an ERISA claim.

Internal appeal first. Priya has 180 days from the adverse determination to file. Because the service is already rendered, the plan has up to 60 days to decide a post-service appeal (30 days for a pre-service appeal; 72 hours if expedited because a delay would seriously jeopardize health). She should request the specific clinical criteria relied on, the identity and credentials of the reviewer, and a peer-to-peer discussion with the plan's medical director.
External review second. If the internal appeal is denied in whole or part, she has 4 months from that final denial to request an independent external review. For a Colorado-regulated non-grandfathered individual plan, the Colorado Division of Insurance administers the process and assigns an independent review organization. Standard decisions issue within 45 days; expedited within 72 hours.
Why not ERISA. ERISA governs employer-sponsored plans. Priya bought individual coverage on the exchange, so her remedies run through the ACA appeals rules and the Colorado DOI, not the Department of Labor. Filing an ERISA claim would simply be bounced, which is a common and costly error in this fact pattern.
3. Priya asks whether she must pay the hospital and the out-of-network doctors before she can appeal. What do you advise?
Read the worked answer
No. Payment is not a precondition to appeal. Filing the internal appeal preserves her rights regardless of whether the bill has been paid.
What she should actually do:
- Pay only the in-network cost sharing the plan calculates. Her exposure is capped at the $9,200 OOP maximum, and if the denial is overturned she will have overpaid and is entitled to a refund of the excess.
- Send each out-of-network provider a written notice citing the No Surprises Act and Colorado's balance-billing law, with the claim number and a demand that the bill be withdrawn and resubmitted to the plan.
- If either persists, file a complaint with the Colorado Division of Insurance and a federal NSA complaint; both have enforcement authority over this exact conduct.
Watch the interaction. If the medical-necessity denial is reversed, the admission is reprocessed at the in-network rate, her cost sharing is recalculated, and the OOP maximum still caps her at $9,200. If the emergency services were never counted toward the OOP maximum in the first place, that is a separate processing error and should be raised in the same appeal.
