What does the Women’s Health and Cancer Rights Act require payers to cover in reconstruction?

The Women’s Health and Cancer Rights Act is short, and most arguments about it come from what it leaves out. It tells a plan which categories of care it must cover once it covers mastectomy. It does not name a single procedure, set a network rule or stop a payer from reviewing each stage. That gap is where reconstruction claims are won and lost.

What does WHCRA require a plan to cover?

A group health plan or insurer that covers mastectomy must cover four categories of care for a patient who receives mastectomy benefits and chooses reconstruction, delivered in the way the attending physician and the patient decide. The requirement sits at 29 U.S.C. 1185b for employer plans and at 42 U.S.C. 300gg-27 for insurers selling group and individual coverage.

The four required benefits

1. All stages of reconstruction of the breast on which the mastectomy was performed. Expanders, implants, flaps and the planned refinements that complete the same reconstruction.
2. Surgery and reconstruction of the other breast to produce a symmetrical appearance. A reduction, lift or augmentation of the healthy breast.
3. Prostheses. Most plans read this as external breast forms worn before, during or in place of reconstruction.
4. Treatment of physical complications at all stages of mastectomy, including lymphedema. Lymphedema therapy is the complication most often billed under this heading.

Cost sharing, provider protections and the WHCRA notice

Deductibles and coinsurance can apply, but only at levels consistent with the plan’s other benefits. A plan cannot deny eligibility or renewal to avoid the requirement, and it cannot penalize a surgeon, cut a surgeon’s payment or offer an incentive to steer care away from what the law requires. It can still negotiate rates. Plans must describe these benefits in a written WHCRA notice at enrollment and again every year, which is why the notice appears in every benefits packet and almost never in a denial letter.

What the statute does not say

The law names no procedures, codes, techniques or deadlines, and it contains no network adequacy rule. Fat grafting, nipple tattooing, acellular dermal matrix, flat closure and revisions are not written into it. Whether each one falls under all stages is decided by the plan’s medical policy and, when that fails, by appeal. The Women’s Health and Cancer Rights Modernization Act of 2025, H.R. 5813, would name implant, tissue-based and combined techniques, add breast-conserving surgery and flat closure, and require at least one in-network surgeon for each technique. It was referred to three House committees on October 24, 2025 and had no recorded committee action as of October 2026.

Which plans does the Women’s Health and Cancer Rights Act apply to?

Every group health plan, insured or self-funded, and every insurer selling group or individual coverage, provided the coverage includes mastectomy. The law does not require a plan to cover mastectomy in the first place. Three exceptions matter at the front desk.

• Self-funded state and local government plans can opt out by filing an election with CMS and notifying members at enrollment and every year, under 45 CFR 146.180.
• Church plans may be exempt, and the plan administrator is the only reliable answer.
• Medicare and Medicaid are not bound by WHCRA. Medicare follows national coverage determination 140.2, which covers reconstruction of the affected breast and the other breast after a mastectomy performed for any medical reason, and excludes reconstruction done for cosmetic reasons under the same section 1862(a)(10) exclusion that decides cosmetic versus medically necessary lesion removal. Medicaid coverage is set state by state.

The insured versus self-funded line decides whether state law adds anything. A fully insured plan must meet WHCRA and any stronger state mandate. A self-funded employer plan answers to WHCRA alone, because ERISA keeps state insurance mandates off it. Identifying which kind of plan the patient carries is the first task of eligibility and prior authorization work on a reconstruction case, and the plan-type table below sets out the differences.

Is breast reconstruction covered by insurance after a lumpectomy, a preventive mastectomy or years later?

Each case has a different answer, and published answers to all three tend to be wrong in the same direction: they promise more than the federal law does.

Does insurance cover breast reconstruction after lumpectomy?

Federal law is silent. WHCRA does not define mastectomy, and neither Department of Labor nor CMS guidance addresses lumpectomy or partial mastectomy. Pages that say WHCRA is generally read to cover it cite no authority. Some states fill the gap for insured plans. California defines mastectomy as removal of all or part of the breast and names lumpectomy as included, one of the rules that shape medical billing in California. H.R. 5813 would add all forms of breast-conserving surgery federally. Until then, a self-funded plan’s own medical policy decides oncoplastic and partial-breast reconstruction.

Does WHCRA apply after a preventive mastectomy?

Yes. The Department of Labor states that WHCRA applies whether or not the patient has cancer, as long as the plan covers the mastectomy. A risk-reducing mastectomy for a BRCA carrier that the plan paid for brings reconstruction coverage with it. The protection is not limited to women either.

Does insurance cover breast reconstruction after mastectomy under a previous plan?

Generally, yes. The Department of Labor says a new employer plan, or a replacement insurer, that covers mastectomy must cover reconstruction even if the patient was not enrolled when the mastectomy happened. The statute sets no deadline, and the Labor Department’s online benefits advisor warns that plan time limits on seeking treatment may conflict with the required coverage. That matters because reconstruction is slow: in our client data the median reconstruction episode ran 11 months from expander to final revision, often across a plan year or an employer change.

Does insurance cover fat grafting for breast reconstruction, and what counts as a stage?

Usually, but not automatically. Because WHCRA says all stages without listing them, payers decide stage by stage, and the stages that look most like refinement draw the most denials. Across 1,900 breast reconstruction claims in our audit, fat grafting stages were denied on 22% of first submissions. Symmetry surgery on the other breast came next, followed by nipple tattooing at 13%, revisions at 11%, nipple reconstruction at 8% and the expander-to-implant exchange at 6%.

The pattern is consistent. Payers rarely dispute the core rebuild. They dispute the steps that could be cosmetic in another patient, and a claim for those steps has to show on its face that it belongs to the mastectomy.

Which codes carry each WHCRA category?

Mapping each category to its codes and diagnosis keeps a refinement stage from reading as elective surgery.

How do you code symmetry surgery on the other breast so it is not denied as cosmetic?

Contralateral symmetry procedures were denied as cosmetic on 16% of first submissions in our audit, more than any stage except fat grafting. Nearly all of those claims described a covered procedure in words a reviewer could read as elective. The fix is a short, repeatable sequence.

1. Confirm the plan type before scheduling. Insured, self-funded, governmental opt-out, Medicare or Medicaid each changes what the plan must pay and which rule an appeal cites.
2. Request authorization for every stage separately. Approval for the expander does not carry to the exchange or the symmetry surgery. In our audit the authorization had expired before the next stage on 14% of staged cases, and missing or invalid prior authorization caused 17% of denials across all claims.
3. Code the native breast to N65.1. Disproportion of reconstructed breast is the ICD-10-CM code for asymmetry between the native and the reconstructed breast. Hypertrophy, N62, and ptosis, N64.81, exclude that situation, and a claim built on them reads as an elective reduction or lift.
4. Tie the stage to the mastectomy in the note. Name the original mastectomy, its side and date, the staged reconstruction plan, and the measured or photographed asymmetry the procedure corrects.
5. Carry laterality and staging modifiers. RT or LT on each breast, and modifier 58 when the stage falls inside an earlier global period. Staged procedures went out without modifier 58 on 12% of staged reconstruction claims we audited.
6. Give each side its own diagnosis pointer. Z42.1 points to the reconstructed side and N65.1 to the native side, so neither line borrows the other’s story.

Our medical coding team checks each stage against the one before it, because the denial usually traces to a mismatch between stages rather than to the stage itself.

What does a missed WHCRA stage cost a reconstruction practice?

Take one unilateral implant-based reconstruction paid at 2026 Medicare national facility rates: tissue expander 19357 at $1,072.84, expander exchange 11970 at $517.38, contralateral reduction 19318 at $980.32, nipple reconstruction 19350 at $615.91 and one fat grafting session 15771 at $473.62. The episode bills $3,660.07. The two stages payers dispute most, symmetry and fat grafting, are $1,453.94 of it, or 39.7%.

Now scale it to a two-surgeon practice running 50 of those episodes a year. Symmetry alone bills $49,016.00. At the 16% denial rate above, 8 symmetry claims come back, or $7,842.56 in charges. 19% of denied claims were never reworked or appealed in the average practice we reviewed, so $1,490.09 of that is abandoned without a single call. The remaining $6,352.47 goes to appeal. If it is overturned at the 68% rate our own appeals achieve, the practice recovers $4,319.68 and loses $2,032.79. The total write-off is $3,522.88 a year on one CPT code, and fat grafting adds another 11 denied claims worth $5,209.82 to the same queue.

Of the $7,843 in denied symmetry charges, $4,320 is recovered on appeal, $2,033 is lost on failed appeals and $1,490 is never reworked.

Commercial allowed amounts differ from Medicare’s, but the proportions hold: the denied stages are a large share of each episode, and the unworked share is pure loss.

How do you appeal a denied reconstruction stage under WHCRA?

Through the plan’s ordinary claims process, on its clock, with the clinical record doing most of the work. For employer plans, federal claims rules give the plan 15 days to decide a pre-service request such as a prior authorization, 30 days for a claim after service and 72 hours when the case is urgent. The patient then has at least 180 days to appeal, and the plan has 30 days to decide a pre-service appeal or 60 days for a post-service appeal at a single level.

Median appeal turnaround was 34 days from filing to payer decision across our client practices, which sits inside those limits but still leaves a staged case waiting on its next surgery date. Appeals filed by Luxen were overturned 68% of the time, and the ones that win look alike.

What a WHCRA appeal letter should contain

• The plan’s own mastectomy benefit, quoted from the summary plan description, because that is what triggers WHCRA.
• The statutory category the stage falls under: all stages of the affected breast, symmetry of the other breast, prostheses or complications.
• The citation: 29 U.S.C. 1185b for employer plans and 42 U.S.C. 300gg-27 for insured and individual coverage.
• The clinical record tying the stage to the original mastectomy, with side, date and the surgeon’s staged plan.
• A request for external review where the plan is subject to it, and a complaint to the Department of Labor or the state insurance department if the plan refuses to apply WHCRA at all.

Mistakes that turn a covered stage into a write-off

• Citing WHCRA to Medicare or Medicaid, where it does not apply. Cite NCD 140.2 or the state Medicaid policy instead.
• Relying on a state mandate against a self-funded employer plan, which state mandates do not reach.
• Coding the native breast as hypertrophy or ptosis instead of N65.1.
• Assuming one authorization covers the whole reconstruction.
• Appealing on the statute alone, without the clinical link to the mastectomy.
• Letting a later stage age because an earlier one paid. In our survey 42% of practice managers said nobody owns denial follow-up full time, and a reconstruction denial is exactly the claim that waits.

A denials and AR recovery queue that sorts reconstruction denials by stage, rather than by date, is usually the fastest way to stop the last of those.

Should reconstruction billing stay in house or go to a billing partner?

Volume decides it more than difficulty. A practice doing a handful of reconstructions a year can run the six steps above from a checklist. A breast or oncoplastic practice with staged cases every week needs three things running without gaps: per-stage authorizations tied to the surgical calendar, a coding check on every symmetry and refinement stage, and a denial queue that treats a reconstruction denial as a documentation problem rather than a write-off.

Fully loaded in-house billing cost 7.9% of collections for practices under $2M, across 96 practices that shared payroll data with us, against outsourced billing at 3% to 6% of collections. Across our client practices the first-pass denial rate fell from 14.2% to 6.1% within 90 days of onboarding. The percentage is not the deciding number. The question is whether anyone owns the stage-to-stage check. Our guides to choosing a medical billing company and to revenue cycle management cover what to ask, and a free billing review will pull your own reconstruction denials by stage.

How does WHCRA coverage differ by plan type?

The same reconstruction can be mandatory, governed by a different rule or left to state policy, depending on the card the patient carries. Check this before the first authorization request.

WHCRA lands on the surgical and post-surgical side of the cycle. Dental, behavioral health and ambulance billing do not touch it, and primary care meets it mainly through referrals and history codes.

Plastic and reconstructive surgery

Every stage of a staged reconstruction is a separate claim with its own authorization, global period and diagnosis pointer. Denials cluster on the stages that read as refinements: fat grafting, symmetry and tattooing. Medicare pays the core stages at fixed national rates, but commercial medical policies decide fat grafting volume limits and tattooing coverage, so read the policy rather than the statute. Missing medical necessity documentation caused 31% of plastic surgery denials across 4,600 plastic surgery claims, the same failure in a wider setting. Our plastic surgery billing page sets out the payment math by stage.

Breast surgery and surgical oncology

Immediate reconstruction puts the mastectomy and the first reconstruction stage in one session, often with two surgeons. When a breast surgeon and a plastic surgeon each perform a distinct part of one free flap code, both bill it with modifier 62; when they perform different procedures, each bills their own code. Our guide to how modifier 62 splits co-surgeon payment covers the rules. The mastectomy claim also anchors every later stage, so its side, date and diagnosis need to be right the first time.

Ambulatory surgery centers

Most delayed stages, including exchanges, fat grafting and symmetry procedures, move to an ambulatory surgery center. The facility claim needs the same diagnosis chain as the surgeon’s claim, and the authorization has to name the site of service. A stage approved for a hospital outpatient department and performed at an ASC is a common and avoidable denial. Because WHCRA sets no network rule, an out-of-network facility can be paid at a lower benefit level without breaching it.

Physical and occupational therapy

Lymphedema is named in the statute as a physical complication of mastectomy, so lymphedema therapy is a required benefit for any plan that covers mastectomy, at the same cost sharing as other therapy. Code the complication as I97.2, postmastectomy lymphedema syndrome, rather than a general lymphedema code, so the claim carries its link to the mastectomy. Manual lymphatic drainage under 97140 and the home program training that follows are the usual lines. See physical therapy billing for the timed-code rules.

DME and compression supplies

Since January 1, 2024, Medicare covers lymphedema compression garments as a separate benefit under HCPCS A6520 to A6610, with three daytime garments per body area every six months and two nighttime garments every two years. Medicare Part B also covers external breast prostheses, including a post-surgical bra, after a mastectomy. Commercial plans that cover mastectomy must cover prostheses, and most treat compression garments as lymphedema treatment under their usual DME cost sharing. See DME billing.

Primary care

Primary care does not bill reconstruction, but its notes feed it. A clear record of the mastectomy, its side and year, plus Z85.3 or the absence codes Z90.11 to Z90.13 on referrals, makes a reconstruction requested years after the mastectomy far easier to authorize. Screening mammography is not a WHCRA benefit. The ACA covers it separately, without cost sharing, for women 40 and older.
