Plastic surgery billing is a tale of two practices: the reconstructive work that insurance pays, and the cosmetic work that patients pay out of pocket. The line between them isn't always obvious, and payers know it, which is why reconstructive plastic surgery claims get scrutinized heavily. The dollars add up quickly: even a modest error rate here means avoidable revenue loss every year.
If you're working through these issues, our specialty billing services can help you address them systematically.
Insurance covers surgery to correct a functional impairment or a condition resulting from disease, trauma, or congenital abnormality. Cosmetic surgery, performed solely to improve appearance without a functional basis, is not covered. The same procedure can be reconstructive or cosmetic depending on the clinical indication.
Rhinoplasty for a deviated septum causing breathing obstruction, reconstructive. Rhinoplasty to change the shape of the nose, cosmetic. Blepharoplasty causing ptosis that obstructs the visual field, reconstructive. Blepharoplasty for baggy eyelids without functional impairment, cosmetic. The documentation has to make this distinction explicit.
Breast reconstruction following mastectomy is federally mandated to be covered by the Women's Health and Cancer Rights Act. This includes reconstruction of the affected breast, surgery to achieve symmetry of the opposite breast, and prostheses and physical complications. The WHCRA applies to all group health plans that cover mastectomy.
Bill reconstruction using CPT codes for the specific technique: 19340–19342 for implant-based reconstruction, 19357 for tissue expander, 19361–19369 for flap procedures (TRAM, DIEP, etc.). Each technique has specific documentation requirements around the type of reconstruction, the mastectomy that preceded it, and the reconstruction plan.
Excision codes differ based on whether the lesion is benign (11400–11471) or malignant (11600–11646). The distinction requires a pathology result. You can code based on clinical impression at the time of service, but if pathology comes back different, you may need to recode. Build a workflow to reconcile pathology results with billed codes within your timely filing window.
Size matters for excision coding; the code is selected based on the excised diameter including margins. Document the lesion size AND the total excision size including margins. Not just one or the other.
Plastic surgeons often repair complex wounds. The repair codes (12001–13160) are stratified by type (simple, intermediate, complex) and length in centimeters. Lengths of repairs of the same complexity can be added together across similar anatomic areas. Don't bill each laceration separately when they can be combined, and don't combine lacerations of different repair types or anatomically distinct regions.
Local flaps (14000–14302) and free flaps have their own codes. The flap size is measured as the area of primary and secondary defects, not just the flap itself. Documentation needs the dimensions of both.
Cosmetic procedures are non-covered and patient-pay. The billing implications: you don't submit to insurance (doing so for cosmetic procedures is fraud), you collect from the patient directly, and you don't need to accept Medicare assignment rates. Your practice sets the price.
Financial counseling before cosmetic procedures is essential. Patients need a clear understanding of the cost, what's included in the surgical fee versus anesthesia versus facility, and your collection policy. Practices that handle this poorly end up in payment disputes that are hard to resolve after the service is provided.
Most plastic surgery procedures have 90-day global periods. Post-operative visits within that period are included in the surgical fee. But if a complication arises requiring a return to the OR, a new global period may start. Use modifier -78 for returns to the OR for complications of the original procedure. Use modifier -79 for procedures unrelated to the original surgery during the global period.

For a reconstructive claim to hold up, the record has to show the functional problem, not just the anatomy. If a patient has excess skin causing chronic rashes, describe the symptoms, how long they've lasted, and what conservative treatment was tried. If a nasal procedure is meant to fix breathing, document the obstruction and the exam findings. Photographs, measurements, and prior treatment notes all help.
Payers publish medical policies for the common procedures, and those policies list the criteria. Read the policy for each payer before you request authorization, and write the note to address each criterion. When the policy says a patient must have failed six weeks of conservative care, the chart should show six weeks of conservative care.
When a patient has both cosmetic and reconstructive goals in the same operation, the record and the billing have to separate them. Document which portion of the surgery is medically necessary, bill only that portion to insurance, and quote and collect the cosmetic portion from the patient. A consent and financial agreement that spells this out in advance prevents disputes and protects the practice.
Train the front desk and the surgical coordinators to use the same words, too. A patient who hears "insurance will probably cover this" from one person and "it's cosmetic" from another is likely to complain, and a complaint often leads to a review.
Most plastic surgery procedures carry a 90-day global period, and complications don't always wait for a convenient time. If the patient returns to the operating room, a modifier and separate documentation may be needed. If the patient comes in for an unrelated problem, a different modifier applies. Build a short decision guide for your billers that lists the common scenarios and the right modifier for each, and keep the operative note attached to every claim that uses one.
For every reconstructive case, use a pre-authorization checklist that lists the payer's criteria and what the chart shows for each one. Attach photographs and measurements where the policy calls for them. If a criterion isn't met, decide with the surgeon whether to appeal, wait, or discuss cosmetic pricing with the patient before scheduling.
That conversation up front, with a written financial agreement, prevents most disputes later.
Reconstruction is billed in stages, and each stage has its own code and payment. At 2026 Medicare rates, tissue expander placement (19357) pays $1,072.84 and the later exchange for an implant (19342) pays $694.40, so one patient generates $1,767.24 across the two surgeries. A latissimus flap reconstruction (19361) pays $1,382.13, and a two-pedicle TRAM flap (19369) pays $1,755.89.
A practice that does 12 expander cases a month earns $12,874 from the first stage alone.
Because the second stage happens months later, it's the one that gets lost. If 3 of 12 patients a month have no authorization on file for the exchange, that's 3 surgeries at $694.40 each, or $2,083.20 at risk every month and $24,998 a year.
Track the second-stage authorization at the time of the first. Put the expected date on a worklist, and confirm approval at least 30 days before the OR date, so the schedule and the payer agree.
Insurance covers surgery that corrects a functional impairment or a condition resulting from disease, trauma, or a congenital abnormality. Surgery done solely to improve appearance is cosmetic and isn't covered, as the article explains.
Yes. The article notes the Women's Health and Cancer Rights Act requires coverage, including reconstruction of the affected breast and surgery on the other breast to achieve symmetry.
No. The article says submitting cosmetic procedures to insurance is fraud. They're patient-pay, so collect directly from the patient and document that the service was cosmetic.

Revenue check: Because contractors can extrapolate a sample error rate across the full lookback period, a documentation gap that looks minor on paper can become a much larger repayment demand. A brief monthly reconciliation between what was documented and what was billed in this area is one of the highest-return habits a billing team can build, it catches revenue leakage and audit exposure in the same pass.
Keep this on a schedule: A short monthly reconciliation between what was documented and what was billed is one of the cheapest habits a billing team can build. For most practices it's the difference between catching a $10,000 to $25,000 problem early and finding it during an audit.
