Appendectomy, an Out-of-Network Anesthesiologist, and a Denied MRI
Maya, 41, is covered by a non-grandfathered ACA-compliant PPO through her employer: $2,000 individual deductible, $4,000 family deductible, 20% in-network coinsurance after the deductible, a $40 office-visit copay that does not apply to the deductible, a $7,500 individual in-network out-of-pocket maximum, and a separate $12,000 out-of-network maximum with 50% coinsurance and balance billing permitted. By March she has paid $1,400 in allowed charges toward her deductible. In April she has an emergency appendectomy at an in-network hospital. Allowed amounts are: hospital $22,000; in-network surgeon $4,300; anesthesiologist $2,100 allowed, billed at $3,600. The anesthesiologist is out of network and was assigned to the case without any notice or consent form. In June the anesthesiology group bills Maya $1,500 for the balance. In July the plan denies a follow-up MRI as not medically necessary, citing an internal guideline.
1. Assuming the hospital claim processes first, calculate Maya's total cost sharing for the April claims. Has she met her out-of-pocket maximum?

Step 1 - remaining deductible. $2,000 − $1,400 = $600 left, all consumed by the $22,000 hospital claim.
Step 2 - hospital coinsurance. ($22,000 − $600) × 20% = $4,280. Hospital cost sharing: $600 + $4,280 = $4,880.
Step 3 - surgeon. Deductible is satisfied, so $4,300 × 20% = $860.
Step 4 - anesthesiologist. Even though the provider is out of network, the No Surprises Act treats this ancillary service at an in-network facility as in-network for cost-sharing purposes absent a valid written notice and consent. $2,100 × 20% = $420. Note that if the plan applied out-of-network rules, the $2,100 would hit the separate $4,000 out-of-network deductible and then 50% coinsurance, and only that cost sharing would count toward the $12,000 out-of-network maximum - a materially worse outcome the statute is designed to prevent.
Total. $4,880 + $860 + $420 = $6,160.
Out-of-pocket maximum. She has not met it. The $7,500 in-network maximum includes deductible and coinsurance (and copays, which count toward the maximum but not the deductible). She has $1,340 of room remaining before the plan pays 100% of covered in-network services for the rest of the plan year. The $40 office copays she paid earlier also count toward the $7,500, so her actual remaining room is slightly smaller than $1,340.
2. Is Maya obligated to pay the $1,500 balance bill? What are her options, and how would the analysis change if she had signed a notice?
Read the worked answer
She is probably not obligated. The No Surprises Act prohibits balance billing by out-of-network providers of ancillary services (anesthesiology, radiology, pathology, hospitalist, intensivist, assistant surgeon) at an in-network facility for non-emergency care unless the patient received a written notice and gave consent at least 72 hours before the scheduled service (same-day for urgent services). The notice must state that the provider is out of network, list an in-network alternative and a good-faith estimate, and be separate from other consent forms. Maya received no notice, so:
- Her cost sharing is capped at the in-network rate - the $420 already calculated.
- The provider must stop billing her and instead pursue the plan, using the open-negotiation and independent dispute resolution (IDR) process. The dispute is between the plan and the provider.
Action steps. Do not pay the $1,500. Call the number on her ID card, ask the plan to confirm the claim was processed under No Surprises Act protections, ask the provider in writing for any signed consent form (a form buried in admission paperwork is not valid), and file a complaint with CMS at 1-800-985-3059 or with the state department of insurance if the bill is not withdrawn.
If she had signed a valid notice, she would owe the balance bill ($3,600 − $2,100 = $1,500, on top of her cost sharing on the allowed amount), and that cost sharing would count toward her out-of-network accumulators, not the in-network maximum.
3. The MRI is denied as not medically necessary. Lay out Maya's appeal rights and the deadlines that apply.
Read the worked answer
The denial notice itself is a compliance document. It must be in writing, state the specific reason, cite the clinical guideline used, explain the internal appeal and external review rights, and provide the diagnosis and procedure codes and the criteria on request. If any of that is missing, that is a separate basis for challenge.
Internal appeal. Maya has 180 days from the denial to file. Because this is a post-service claim, the plan must decide within 60 days on a standard appeal (one 60-day extension is permitted if more information is needed). If the service were still pre-service, the deadline would be 30 days; an expedited appeal, available when the standard timeline could seriously jeopardize her health, must be decided within 72 hours.
External review. If the internal appeal is upheld, she must request external review within 4 months of the final internal denial, and an independent review organization decides within 45 days (72 hours expedited). The plan pays for the review. Because her plan is fully insured, the state external review process applies, but the ACA requires an equivalent federal process either way.
Practical leverage. Submit the ordering physician's letter documenting symptoms, prior conservative treatment, and what the guideline requires; ask the plan which specific criterion was not met; and ask whether the denial was made by a physician in the same specialty. A common outcome is reversal at the internal stage once the plan has the full clinical record, so filing the appeal is almost always worth it even for a modest claim.
