Out-of-network underpayments and NSA IDR for plastic and reconstructive surgeons
Yes, plastic and reconstructive surgeons can recover out-of-network underpayments through the No Surprises Act when they treat patients at in-network facilities or in an emergency. That covers ER call, trauma reconstruction and many assistant or co-surgeon lines. Elective cases where the patient knowingly chose you and an out-of-network facility usually fall outside the Act, and those are handled as commercial out-of-network appeals instead.
Why plastic and reconstructive surgery gets underpaid out of network
Reconstructive work has high billed charges and many line items on one case. A single mastectomy reconstruction can include a flap, a tissue expander, an implant, mesh and a skin closure. Payers pay each line, and they cut most of them.
Four things drive the cuts.
- QPA anchoring. When the No Surprises Act applies, many plans pay the qualifying payment amount, or QPA, which is based on the plan’s own in-network rates. It is often far below what the work is worth. Our guide on the QPA and how out-of-network providers challenge it explains how it is calculated and where it can be questioned.
- Repricers. Plans often send claims to vendors such as Data iSight, MultiPlan, Zelis or Naviguard, which reprice the claim to a fraction of the billed amount.
- Multi-procedure cuts. Plans reduce second and third procedures in the same session. Add-on codes such as each additional 30 sq cm of tissue transfer or a biologic implant for soft tissue reinforcement are often paid at a small fraction, or bundled away.
- Assistant and co-surgeon cuts. When you assist another surgeon’s case, plans often pay a reduced share of the primary fee or deny the line for supposed lack of need.
The result is a familiar pattern: a large reconstruction claim comes back paid at a small share of what was billed, and the practice writes off the difference because the patient cannot be balance billed.
What the federal data shows for plastic and reconstructive codes
The table below comes from the CMS Federal IDR public use file. It shows the plan’s median QPA next to the median award across disputed line items for plastic and reconstructive codes. Awards in decided disputes were far above the QPA on every code listed.

These numbers are not a promise for your claims. Every dispute turns on the plan, the service, the facility and the evidence. They do show that the QPA is not the ceiling, and that the federal process is used for reconstruction, breast surgery, flaps and wound closure.
Where the No Surprises Act applies to your practice
The Act applies by situation, not by specialty. Here is how it sorts out for a plastic and reconstructive practice.
ER call and trauma reconstruction
If you take call and treat an emergency patient at a hospital that is in network with the plan, but you are not, the Act generally protects the patient from balance bills and gives you the right to dispute the payment. That includes facial trauma, hand injuries, burns and complex wound repair, and it can reach follow-on care until the patient can be moved or can choose a provider.
Reconstruction after mastectomy
Many reconstruction cases begin as another surgeon’s mastectomy at an in-network hospital. If you are out of network with the plan and the facility is in network, you generally fall inside the Act. If the patient scheduled with you in advance, an out-of-network facility is involved and you gave the required notice and consent, the case is more likely a commercial out-of-network claim. Check the paperwork before you decide which route fits.
Assistant and co-surgeon lines
You may bill as an assistant or co-surgeon on another specialty’s case, such as a breast, head and neck, trauma or ortho case. When the facility is in network and you are not, those lines can be disputed like any other. Plans often cut or deny them first. Our article on out-of-network assistant surgeons recovering underpaid claims covers that side in more detail.
Cosmetic work is out of scope
Cosmetic procedures are paid by the patient, so there is no insurance claim and nothing to dispute. Keep them out of any underpayment review. If a case starts as cosmetic and turns medical, such as a complication or a revision that the plan covers, review the facts for that case.
Elective out-of-network cases with notice and consent
When a patient knowingly chooses an out-of-network surgeon at an out-of-network facility and signs proper notice and consent before the service, the Act usually does not apply. Your remedy is then a commercial out-of-network underpayment appeal under the plan’s terms and your state’s rules. State law differs here, so talk to counsel where it is unsettled. Our page on out-of-network underpayment recovery covers that route.
Self-funded and fully insured plans
Not every plan falls under the federal process. Some fully insured plans follow a state process instead. See whether your claim is eligible for federal IDR before you file.
The deadlines that matter
Two clocks decide whether you can dispute a claim.
- Open negotiation. After you get the initial payment or denial, you have 30 business days to start open negotiation with the plan. The plan and the practice then have 30 business days to try to settle. Our guide to starting the open negotiation clock has a notice template.
- IDR initiation. If negotiation fails, you have 4 business days after the 30-business-day negotiation period ends to start federal IDR. Miss it and the claim is generally out of the federal process.
The CMS site has the official No Surprises Act resources if you want to read the rules directly. For a walk through each stage, see the federal IDR process for providers, step by step.
What to do about claims you already accepted
Many practices wrote off underpayments months ago and assume it is too late. Often it is not. Some claims can still be disputed, and some cannot, depending on the date of service and the plan. We review claims back to 2022 and sort them into open, closed and worth a closer look.
Start with the claims that carry the largest billed amounts: flaps, tissue expanders, implant lines and breast reconstruction after mastectomy. A few large claims can matter more than hundreds of small ones.
Filing yourself or handing it off
You can file disputes yourself. Many small practices do, and many lose. The common failure points are:
- Default losses. A missed deadline or an incomplete submission can end the dispute before anyone looks at the merits.
- Ineligible batches. Grouping claims that should not be batched together can get the whole filing rejected.
- Weak offers. The reviewer picks one side’s number. An offer that cannot be supported loses to the QPA.
- Too few filings. Practices that file a handful each year leave the rest unpaid.
Each of these is fixable, but each takes time a surgeon and an administrator do not have between cases. Our page on No Surprises Act IDR recovery explains how the full process works end to end.
How Happy Billing works with plastic and reconstructive practices
Happy Billing recovers out-of-network and No Surprises Act underpayments for independent specialty practices. We run open negotiation and federal IDR in-house, from the first notice to the final award. We work on contingency, so we are only paid from what we recover.
You do not have to switch billers. We work alongside your current biller and take the underpaid claims off their plate. We also take practices that national recovery firms consider too small.
The free review starts with your claims. We flag what is recoverable, which claims qualify for federal IDR, and which belong in a commercial appeal. Then we give you a clear number so you can decide.
Frequently asked questions
Does the No Surprises Act cover my breast reconstruction claims?
It can. If you treated the patient at an in-network hospital or surgery center and you are out of network with the plan, the claim is usually covered, and you cannot bill the patient the difference. If the patient chose you and an out-of-network facility with proper notice and consent, the Act usually does not apply and you appeal under the plan’s out-of-network terms instead.
Can I dispute a payment I already accepted?
Often, yes. A payment sitting in your bank account does not always close the claim. Whether it can still be disputed depends on the date of service and the plan type, so we review claims back to 2022 and sort out which ones are still open.
Can I use the federal process for cosmetic surgery?
No. Cosmetic work is normally paid by the patient, so there is no insurance claim to dispute. The federal process covers insured medical services, such as reconstruction, emergency care and medically necessary procedures.
Who handles IDR for a small plastic surgery practice?
You can file yourself, hand it to your current biller, or use a recovery firm. Many national firms turn away small practices. Happy Billing runs open negotiation and federal IDR in-house for independent practices, and we work alongside your current biller.
What does it cost to have Happy Billing review my claims?
The review is free. If we take on recovery work, it is on contingency, so we are only paid from what we recover.
Next step
If you take ER call, do reconstruction after mastectomy or assist on other surgeons’ cases, there is likely a set of claims worth a second look.
