Top denials in plastic surgery billing services: reconstructive versus cosmetic claims

How do we tell a reconstructive claim from a cosmetic one?

Medicare decides by purpose and function, not by code. Chapter 16, section 120 of the Medicare Benefit Policy Manual defines cosmetic surgery as any procedure directed at improving appearance, except surgery for the prompt repair of accidental injury or to improve the functioning of a malformed body member. The rule is codified at 42 CFR 411.15(h).

The code cannot settle it. A coverage policy from CGS Administrators, which covers Kentucky and Ohio, says current CPT codes cannot separate cosmetic from reconstructive nasal surgery, so each case is sorted by the presence or absence of signs or symptoms. The 2026 fee schedule file shows the same split: upper blepharoplasty 15822 has status A, while abdominal skin excision 15830 and rhinoplasty 30400 to 30420 have status R, restricted coverage with contractor pricing if covered.

Before the date of service the chart needs the symptom in the patient's words and the surgeon's measurements, the conservative treatment tried and for how long, labelled photographs where the policy asks for them, and an operative note that matches the code. A complication of cosmetic surgery can be covered when reasonable and necessary, but chapter 16 says visits a global fee would include are not.

What proves medical necessity for a breast reduction?

Medicare contractors want symptoms that persisted despite conservative care, not breast size alone. Local coverage determination (LCD) L35001, published by Wellpoint Federal for jurisdictions 6 and K, calls the surgery necessary when symptoms interfered with daily activity for at least 6 months despite conservative management, with one of three findings: back or shoulder pain not relieved by analgesics, garments, therapy or weight correction; significant arthritic change in the cervical or upper thoracic spine; or skin maceration or infection under the breast, or shoulder grooving, that did not respond to treatment.

L35001 lists tissue weights by body surface area but calls them guidelines, not rules. CGS in Kentucky and Ohio (L39506) applies the Schnur scale, a table of grams removed per breast for each body surface area, and treats the case as necessary above the 22nd percentile.

Commercial plans start with the benefit. UnitedHealthcare policy MP.004.32 says most of its plans exclude breast reduction except as the Women's Health and Cancer Rights Act requires, some allow it to treat a physiological functional impairment, and necessity is judged against InterQual criteria.

How do we bill bilateral breast procedures?

For Medicare, report a bilateral reduction once with modifier 50 and one unit. Chapter 12, section 40.7 of the Claims Processing Manual says a code not described as bilateral is reported once with modifier 50, and that bilateral indicator 1 pays 150 percent of the fee schedule amount. The 2026 file gives 19318, 19316, 19325, 19357 and 19364 indicator 1. The manual notes this differs from CPT, which uses two lines, so read each commercial policy. An ambulatory surgery center reports two lines with LT and RT (NCCI chapter III, section K.5).

What does the Women's Health and Cancer Rights Act require for breast reconstruction?

The Women's Health and Cancer Rights Act (WHCRA) requires a group health plan that pays for a mastectomy to cover reconstruction when the patient elects it. Under 29 U.S.C. 1185b, which is ERISA section 713, the plan must cover all stages of reconstruction of the breast where the mastectomy was done, surgery on the other breast to produce a symmetrical appearance, and prostheses and physical complications, including lymphedema. Deductibles and coinsurance may apply if they match the plan's other benefits.

The symmetry procedure on the healthy breast is the claim most often denied as cosmetic. Document the mastectomy, the decision to reconstruct and the symmetry plan in one note, and cite the Act in the appeal. UnitedHealthcare states that all its plans cover breast reduction that qualifies under the Act.

Original Medicare is outside the Act. National coverage determination (NCD) 140.2, effective January 1, 1997, allows payment for reconstruction of the affected and the contralateral breast after a medically necessary mastectomy, and not for cosmetic reasons.

How do we bill staged breast reconstruction?

Bill each planned stage with modifier 58 when it falls inside the global period of the earlier stage. Chapter 12 of the Claims Processing Manual says a new postoperative period begins when the next procedure in the series is billed, and that 58 is not for a problem that returns the patient to the operating room, which is 78. The 2026 file gives a 90-day global period to expander placement (19357), immediate and delayed implants (19340, 19342), nipple reconstruction (19350) and flap reconstruction (19361, 19364, 19367, 19369). Modifiers 57, 58, 78 and 79 are on our general surgery billing page.

NCCI chapter III, section J sets three rules that drive reconstruction edits.

• A reconstruction code that includes an implant is not reported with a separate implant code
• Flap code 15734 is not reported with 19357 to 19364, 19367 to 19369, 19340 or 19342, because the flap is included
• Codes 19357 to 19369 include adjacent tissue transfer such as 14000, unless it is at an unrelated site

Which plastic surgery procedures need Medicare prior authorization?

Medicare requires prior authorization for blepharoplasty, panniculectomy and rhinoplasty, plus botulinum toxin and vein ablation, when done in a hospital outpatient department. These categories apply from July 1, 2020 under 42 CFR 419.83(a)(1). Under 419.82(b)(1), CMS or its contractor denies a listed service if the provider has no provisional affirmation.

The request goes in before the service and before the claim, with the documentation showing Medicare coverage, coding and payment rules are met. The decision is due within 7 calendar days, or 2 business days for expedited review when delay would seriously jeopardize the patient's life, health or ability to regain maximum function. After a non-affirmation the provider may resubmit. An affirmation is provisional: section 419.82(b)(2) lets the contractor still deny for technical requirements or information not available at the time.

For ambulatory surgery centers, CMS runs a voluntary demonstration for the same five categories; an ASC that skips it faces prepayment review. It began for dates of service on or after January 19, 2026 in California, Florida, Tennessee, Pennsylvania, Maryland, Georgia and New York, and February 16, 2026 in Texas, Arizona and Ohio. See our prior authorization page.

What do Medicare policies require for eyelid, abdominal and nasal surgery?

Each Medicare Administrative Contractor (MAC) writes its own policy, so the test depends on the surgeon's location. Open the policy your MAC currently publishes before building a checklist. These four show how the tests differ.

The CGS policy excludes abdominal wall laxity, diastasis recti, redundant tissue after weight loss without refractory infection or inflammation, and anything done solely for appearance. If a cosmetic procedure shares a session with a covered one, only the covered one is paid. NCCI chapter VIII bundles upper blepharoplasty (15822, 15823) into ptosis repair (67901 to 67908) on the same eyelid; the other eyelid may bypass the edit. Ptosis and visual field rules are on our ophthalmology billing page.

How do we code flaps, wound repairs and skin substitutes?

An adjacent tissue transfer (14000 to 14350) already includes excision and repair of the same defect. NCCI chapter III, section H says codes 11400 to 11646 and 12001 to 13160 are not reported with it, and debridement is included. Extensive undermining may be a complex repair, not a transfer, because a transfer requires adjacent tissue to be incised and carried over. A graft with a transfer is separately reportable when the descriptor does not include grafting. Repairs after lesion removal are on our dermatology billing page.

Skin graft and substitute codes are sorted by size, site and type. The primary code, such as 15271, takes one unit, and add-ons such as 15272 (ZZZ global) cover more area. Debridement before the graft is included.

The product is paid apart from the application. In the CY 2026 physician fee schedule final rule, CMS pays a skin substitute as an incident-to supply when used in a covered application in the non-facility setting or under the hospital outpatient system, at an initial rate of about $127.28 per square centimeter before geographic adjustment for PMA, 510(k) and registered 361 HCT/P products. Non-sheet products are priced by the MACs, and CMS will update rates annually. Coverage and debridement are on our wound care billing page.

When is modifier 22 justified on a plastic surgery claim?

Only when the work was substantially greater than the code describes. Chapter 12, section 40.2.A.10 requires a concise statement and the operative report, and limits 22 to codes with a 0, 10 or 90-day global. The note must say what made the case harder. See our modifier 22 page.

How do we handle self-pay cosmetic cases and the ABN?

For a cosmetic Medicare case, an Advance Beneficiary Notice (ABN) is optional but worth issuing. Chapter 30, section 50.2.1 of the Claims Processing Manual says an ABN is not required for statutorily excluded care, though CMS strongly encourages one, with no option box. NCCI chapter VIII adds that ABN instructions apply to a cosmetic blepharoplasty done with a necessary ptosis repair.

A functional case that may miss the LCD test is different. A denial as not reasonable and necessary under section 1862(a)(1) is on the list where chapter 30, section 50.2 requires an ABN before the service.

For commercial and self-pay patients, the plan document governs. Our workflow is to quote fees in writing, collect the cosmetic portion before surgery and keep it off the insurance claim. When a covered and a cosmetic procedure share a session, we bill the covered one and the patient pays for the rest.
