Does Medicare Cover Breast Reduction Surgery?

Medically necessary vs. cosmetic: the key distinction

Medicare draws a firm line between cosmetic surgery and medically necessary surgery. It will not pay for any procedure done solely to improve your appearance. Reshaping the breasts just because you would prefer a different size or shape is considered cosmetic and is not covered.

Breast reduction (the medical term is reduction mammaplasty) crosses into covered territory when overly large breasts, sometimes called macromastia or breast hypertrophy, are causing real physical problems that surgery can relieve. In that situation Medicare treats the operation as a medical treatment, not a cosmetic one.

Medicare also covers reducing a normal breast so it matches a breast that was rebuilt after breast cancer surgery. This is called symmetry surgery and is part of post-mastectomy care, not cosmetic enhancement.

• Not covered: surgery done only to change the look or size of healthy breasts.
• Covered: reduction for documented physical symptoms that have not responded to non-surgical care.
• Covered: reducing the opposite breast for symmetry after a mastectomy and reconstruction.

What symptoms qualify, and what you must try first

Local Medicare coverage policies (called Local Coverage Determinations, or LCDs) spell out when breast reduction is considered medically necessary. They look for ongoing physical signs and symptoms caused by the weight and size of the breasts.

Typical qualifying symptoms include chronic upper back, neck, and shoulder pain; deep grooves in the shoulders from bra straps; numbness or tingling in the arms; and skin rashes or infections under the breasts that keep coming back. Under most policies these symptoms must have been present for at least six months.

Medicare generally expects that you have already tried non-surgical approaches before it will approve surgery. Your records usually need to show that an endocrine or metabolic cause for the breast enlargement has been ruled out, that you have tried properly fitted supportive garments, and that you have completed a course of medical management (such as prescribed topical or oral medication) for any skin symptoms.

• Symptoms commonly cited: back, neck, and shoulder pain; shoulder grooving from bra straps; recurring rashes or skin infections under the breasts.
• Symptoms usually must have lasted at least six months.
• Conservative care expected first: supportive garments, medical management of skin symptoms, and ruling out a hormonal or metabolic cause.
• Some Medicare contractor policies use a body-surface-area (BSA) chart that sets a minimum amount of tissue (in grams) that must be removed from each breast, which can range from roughly 199 to 238 grams at a smaller body size up to 350 grams or more for a larger body size.

Breast reduction for men and for symmetry after cancer

Enlarged breast tissue in men is a separate condition called gynecomastia. Medicare may cover surgery to remove it when it is medically necessary rather than cosmetic, but the coverage rules and documentation requirements are different from those for reduction in women. If this applies to you, talk with your doctor about whether your case meets your local Medicare policy.

After breast cancer surgery, Medicare covers reducing the size of the remaining healthy breast so it is symmetric with a breast that was reconstructed. This is recognized as part of breast reconstruction following a mastectomy, not as cosmetic surgery.

Which part of Medicare pays, and your 2026 costs

Most breast reductions are done as outpatient procedures. Outpatient surgery is covered under Medicare Part B. In 2026 you first pay the annual Part B deductible of $283, after which Medicare pays 80% of the Medicare-approved amount and you pay the remaining 20% coinsurance. There is no yearly cap on that 20% under Original Medicare. You also must keep paying your Part B premium, which is $202.90 per month for most people in 2026, to keep this coverage.

If your surgery requires an inpatient hospital admission, it falls under Part A instead. In 2026 the Part A inpatient deductible is $1,736 per benefit period. If a stay runs long, days 61 through 90 carry a coinsurance of $434 per day. Most people pay no monthly premium for Part A.

You can get a personalized estimate of the national average outpatient cost for breast reduction (procedure code 19318) using Medicare's Procedure Price Lookup tool, which compares an ambulatory surgical center with a hospital outpatient department and shows your expected share.

Your exact bill depends on where the surgery is done, what your doctor charges relative to the Medicare-approved amount, and whether you have other coverage.

• Outpatient (Part B): $283 deductible (2026), then you pay 20% coinsurance.
• Inpatient (Part A): $1,736 deductible per benefit period (2026); $434/day coinsurance for days 61-90.
• A Medigap (Medicare Supplement) policy can pay some or all of these out-of-pocket costs; what it covers depends on which lettered plan you have.
• Use Medicare's Procedure Price Lookup (code 19318) for a national average outpatient estimate.

Prior authorization, Medicare Advantage, and appeals

Original Medicare does not give you an advance approval before surgery. Instead, your surgeon submits documentation and Medicare decides whether to pay after the claim is filed, based on whether your case meets the medical-necessity rules. That is why thorough documentation matters so much.

Medicare Advantage plans work differently. Many require prior authorization before breast reduction, and their coverage criteria and cost-sharing can differ from Original Medicare. If you are in an Advantage plan, ask your plan for its prior-authorization rules and check your Evidence of Coverage before scheduling surgery.

If Medicare or your plan denies the claim, you have the right to appeal. The denial notice explains the deadline and the steps to file an appeal, and you can submit additional records from your doctor to support medical necessity.

• Original Medicare: no advance prior authorization; the claim is reviewed for medical necessity after surgery.
• Medicare Advantage: often requires prior authorization; rules and costs vary by plan, so confirm with your plan.
• Helpful documentation: a record of symptoms lasting at least six months, conservative treatments tried, photographs, and an estimate of grams to be removed per breast.
• If denied, you can appeal; the denial notice lists the deadline and process.
