Plastic surgery billing turns on a question most surgical specialties never face, which is whether the procedure is reconstructive or cosmetic. The same blepharoplasty, rhinoplasty, or breast reduction can be a covered claim for one patient and a self-pay service for the next, and the only thing separating them is what the chart shows. Add staged reconstructions that run for months, grafts and flaps coded by size and site, and new Medicare prior authorization rules for ambulatory surgery centers, and a plastic surgery practice can lose more to documentation than to any payer rate.
Key Takeaways
- Reconstructive procedures are billed to insurance and need documented functional impairment or a medical cause, while cosmetic procedures are self-pay and should never reach a claim.
- Skin graft, adjacent tissue transfer, and repair codes are chosen by technique, size, and anatomic site, so the operative note has to record measurements.
- The Women’s Health and Cancer Rights Act requires most group health plans to cover every stage of post-mastectomy reconstruction, including symmetry surgery on the other breast.
- Medicare requires prior authorization for blepharoplasty, rhinoplasty, panniculectomy, and botulinum toxin in hospital outpatient departments, and a 2026 demonstration extends it to ambulatory surgery centers in 10 states.
- Self-pay cosmetic patients are entitled to a good faith estimate under the No Surprises Act before the procedure is scheduled.
Reconstructive or Cosmetic
Reconstructive procedures correct abnormal structures caused by congenital defects, trauma, infection, tumors, or disease, or restore function. Cosmetic procedures reshape normal structures to improve appearance. Insurance covers the first group when the record supports it and excludes the second, no matter how the claim is coded.
Most of the procedures that cause trouble sit on both sides of that line. An upper eyelid blepharoplasty is covered when visual field testing and photographs show the lids obstruct vision, and it’s cosmetic when they don’t. A panniculectomy can be covered when the pannus causes recurring skin breakdown that hasn’t responded to treatment, while an abdominoplasty done at the same time is cosmetic and the patient pays for that portion. Breast reduction coverage usually depends on the payer’s criteria for symptoms, failed conservative care, and tissue removed.
The clinical note decides which side a case lands on. It should describe the functional problem, the objective findings, what conservative treatment was tried, and why surgery is needed. A note built around how the patient feels about their appearance won’t support a reconstructive claim, and a note that overstates function for a cosmetic case creates real compliance exposure.
Repairs, Adjacent Tissue Transfer, and Grafts
Wound repairs bill in three tiers, simple (12001 to 12021), intermediate (12031 to 12057), and complex (13100 to 13160). Lengths are added together for wounds of the same tier in the same anatomic group, so three intermediate facial lacerations become one code for the total length. A simple repair after an excision is included in the excision, while intermediate and complex repairs can be billed separately when the note supports the layered or complex closure.
Adjacent tissue transfer codes (14000 to 14302) apply when a local flap such as a rotation, advancement, or Z-plasty closes the defect. The code is chosen by the combined size of the primary defect and the secondary defect the flap creates, and the excision of the lesion is included, so it isn’t billed again.
Skin grafts are coded by type, recipient site, and size. Split-thickness grafts on the trunk, arms, or legs bill as 15100 for the first 100 square centimeters and 15101 for each additional 100, while grafts on the face, scalp, eyelids, neck, hands, feet, or genitalia use 15120 and 15121. Full-thickness grafts bill under 15200 through 15261, also by recipient site and size. Recipient site preparation (15002 to 15005) is reported separately when the note documents it, and skin substitute application uses 15271 through 15278.
Skin substitutes changed in 2026. Medicare now pays most products as incident-to supplies at an initial rate of about $127 per square centimeter, adjusted by locality, instead of at each product’s average sales price. Practices that use acellular dermal matrix or other substitutes in the office should check that their charges and inventory costs reflect the new rate.
Flaps and Breast Reconstruction
Muscle, myocutaneous, and fasciocutaneous flaps bill under 15730 through 15738, and pedicle flap formation uses 15570 to 15576. Free flaps with microvascular anastomosis bill as 15756 (muscle), 15757 (skin), or 15758 (fascia). The operative report has to name the flap, the donor and recipient sites, their dimensions, and the vessels used, or the coder can’t pick a code with confidence.
Breast reconstruction has its own code set. Tissue expander placement bills as 19357, and the later exchange of the expander for a permanent implant bills as 11970. A breast implant placed on the same day as the mastectomy bills as 19340, and on a separate day as 19342. Autologous reconstruction uses 19361 for a latissimus dorsi flap, 19364 for a free flap such as a DIEP, and 19367 through 19369 for TRAM flaps.
The Women’s Health and Cancer Rights Act requires most group health plans that cover mastectomy to cover every stage of reconstruction, surgery on the other breast for symmetry, prostheses, and treatment of complications such as lymphedema. Symmetry procedures like a contralateral reduction (19318) or mastopexy (19316) are often under-billed because staff assume they’re cosmetic. Each stage after the first usually carries modifier 58 when it falls inside the prior stage’s 90-day global period.
Hand Surgery and Burn Care
Plastic surgeons with hand training bill much of their volume in the 26000 series, plus nerve codes such as 64721 for open carpal tunnel release, while endoscopic release bills as 29848. Trigger finger release bills as 26055, and Dupuytren’s contracture can be treated surgically or with a collagenase injection under 20527. Tendon repairs are coded by flexor or extensor, by zone, and by primary or secondary repair, so the zone has to be in the operative note. The Eaton hand surgery code list is a useful reference for the full range.
Burn care bills dressings and debridement by size under 16020 through 16030, with escharotomy under 16035 and 16036, and the percentage of total body surface area has to be documented. Grafting sessions in a burn course are usually planned, so each one carries modifier 58 if it falls inside an earlier procedure’s global period, and a return to the operating room for a complication uses modifier 78 instead.
Modifiers and Global Periods
Most major plastic surgery procedures carry a 90-day global period, and repairs and many minor procedures carry 0 or 10 days. The modifiers below decide whether work inside those windows gets paid.
- 58 for a staged or planned procedure, or one more extensive than the first, during the global period
- 78 for an unplanned return to the operating room for a related complication
- 79 for an unrelated procedure during the global period
- 22 for substantially greater work than usual, with a short narrative and an operative note that explains why
- 50, RT, and LT for bilateral and one-sided procedures, depending on the payer’s rules for each code
- 59 or XS for a separate site or session that would otherwise bundle
An office visit on the same day as a minor procedure needs modifier 25 and a note showing work beyond the usual pre-procedure assessment. Separate-site claims should follow our guide to modifier 59, because using 59 to push past a bundling edit without that support is one of the most common audit findings in surgical billing.
Prior Authorization for Plastic Surgery
Medicare has required prior authorization for blepharoplasty, rhinoplasty, panniculectomy, botulinum toxin injections, and vein ablation in hospital outpatient departments since 2020. The hospital submits the request, but when it’s denied or missing, CMS can also deny related claims for the same procedure, including the surgeon’s.
In 2026 CMS started a five-year demonstration that adds the same five services to prior authorization in ambulatory surgery centers. It began in January 2026 in California, Florida, Georgia, Maryland, New York, Pennsylvania, and Tennessee, and expanded in February to Texas, Arizona, and Ohio. Prior authorization is voluntary under the demonstration, but ASC claims without it go to prepayment medical review. Our guide to ASC billing covers how surgery center claims are handled more broadly.
Commercial plans and Medicare Advantage plans add their own requirements, most often for breast reduction, reconstruction with implants or free flaps, and panniculectomy. A request should include the diagnosis, photographs where required, measurements, conservative treatment history, and the exact codes planned, since an authorization for one code won’t cover a different code added in the operating room.
Cosmetic Procedures and Self-Pay Patients
Cosmetic procedures run outside insurance entirely. The practice sets its own fees, collects before surgery under a written financial agreement, and never submits the procedure to a payer. Submitting a cosmetic procedure as reconstructive to get it paid is false billing, whatever the intent.
Self-pay patients also have federal rights. Under the No Surprises Act, uninsured patients and insured patients who choose not to use their coverage must get a good faith estimate of expected charges before a scheduled procedure, and they can dispute a final bill that comes in substantially higher. When a cosmetic and a reconstructive procedure happen in the same session, the estimate, consent, and operative note should separate the two so each part is billed to the right party.
Plastic Surgery Credentialing
Plastic surgeons certify through the American Board of Plastic Surgery after an accredited residency, written and oral exams, and a case log review. Payers verify that certification along with medical education, residency and fellowship training, every state license, DEA registration, malpractice history, and an NPDB query. Hospital and surgery center privileges are delineated procedure by procedure, so a surgeon who adds microsurgery or hand surgery needs those privileges approved at each facility, and our guide to hospital privileging walks through that process.
Office-based surgical suites need their own attention. Many states require accreditation through AAAASF, AAAHC, or The Joint Commission for office surgery under more than local anesthesia, and many payers won’t pay facility-level or office procedures performed in an unaccredited suite. Practices that also bill skin cancer excisions and Mohs reconstruction should compare notes with our dermatology billing page.
Plastic Surgery Billing FAQ
Is breast symmetry surgery covered after a mastectomy?
Yes, under the Women’s Health and Cancer Rights Act for most group health plans that cover mastectomy. Procedures on the other breast to achieve symmetry, such as a reduction or mastopexy, are covered as part of reconstruction, though many plans still require prior authorization.
Which code applies when a tissue expander is replaced with a permanent implant?
CPT 11970. Tissue expander placement bills as 19357, and the later exchange for a permanent implant bills as 11970, usually with modifier 58 when it falls inside the first stage’s global period.
Does Medicare require prior authorization for blepharoplasty?
In hospital outpatient departments, yes, since 2020. A 2026 demonstration also covers ambulatory surgery centers in 10 states, where claims without prior authorization go to prepayment review.
How are split-thickness skin grafts coded on the face versus the trunk?
Grafts on the trunk, arms, or legs bill as 15100 for the first 100 square centimeters and 15101 for each additional 100. Grafts on the face, scalp, eyelids, neck, hands, feet, or genitalia bill as 15120 and 15121.
Is a panniculectomy covered when an abdominoplasty is done at the same time?
The panniculectomy can be covered when the patient meets the payer’s criteria, such as recurring skin breakdown that hasn’t responded to treatment. The abdominoplasty portion is cosmetic, so the patient pays for it under a separate financial agreement.
Do cosmetic surgery patients need a good faith estimate?
Yes. Under the No Surprises Act, uninsured patients and patients who choose not to use insurance must get a good faith estimate before a scheduled procedure, and they can dispute a bill that comes in substantially higher.
Medwave on Reconstructive and Cosmetic Claims
A plastic surgery claim is usually won or lost in the chart, long before the coder sees it. Medwave checks that each reconstructive case has the functional findings and measurements to support it, keeps cosmetic portions off the claim, and tracks staged procedures through their global periods. Our medical billing team holds a 98% clean claim rate, and we follow the CMS plastic surgery billing and coding article on every Medicare claim it covers.
Our medical credentialing team handles ABPS verification, office suite accreditation records, and payer enrollment, averaging 85 days to approval. Groups with a strong reconstructive volume, especially breast reconstruction, hand surgery, and burn care, have more leverage than they often use, and our payer contracting team builds rate requests around that case mix.
