POLICY

Effective for dates of service after April 9, 2021:

Mastectomy for gynecomastia may be considered medically necessary for adult patients (≥ 18 years of age) with symptoms that have persisted for one year OR adolescent patients (≤18 years of age) with symptoms that have persisted for at least two years when ALL of the following criteria are met:

  • Glandular breast tissue confirming true gynecomastia is documented on physical examination and/or mammography (medical records must contain frontal and lateral view preoperative photographs); AND
  • Gynecomastia is classified as Grade II, III or IV per the American Society of Plastic Surgeons classification; AND
  • Gynecomastia is associated with persistent breast discomfort despite the use of analgesics; AND
  • Presence of an underlying pathologic process (e.g. breast, adrenal or testicular tumors, kidney or liver disease) has been ruled out; AND
  • Use of potential gynecomastia-inducing drugs and substances has been identified and discontinued for at least one year, when medically appropriate; AND
  • Hormonal causes have been excluded by appropriate laboratory testing and, if present, have been treated for at least one year prior to surgery. These include but are not limited to the following as confirmed by laboratory testing:
    • Hyperthyroidism (e.g., thyroid stimulating hormone [TSH])
    • Excess estrogen (e.g., excess estradiol)
    • Prolactinomas (e.g., prolactin)
    • Hypogonadism (e.g., testosterone, human chorionic gonadotropin [hCG], and/or luteinizing hormone [LH])

Mastectomy for gynecomastia is considered not medically necessary in all other circumstances including but not limited to the following

  • Pubertal gynecomastia with tender palpable breast tissue or fatty tissue;
  • Gynecomastia surgery to improve the appearance of the breast or to alter the contours of the chest wall;
  • Surgery to remove excess adipose (fat) tissue (pseudogynecomastia);
  • Use of liposuction to perform gynecomastia surgery

 

Effective for dates of service prior to April 9, 2021:

Mastectomy for gynecomastia may be considered medically necessary for:

  • Adult and mid to late pubertal (age 14 to 20) patients with non-tender, palpable breast tissue;
  • Adult patients with recent onset of progressive breast enlargement with or without tenderness;
  • Patients with Klinefelter’s Syndrome.

The following information will be used to determine if true gynecomastia is present (except in those patients with Klinefelter’s Syndrome). True gynecomastia is defined as the presence of glandular tissue and not fatty tissue:

  • Full history that includes conditions present for at least 12 months on an adolescent, medication history to include drugs, alcohol, and specific questions regarding hepatic dysfunction, testicular insufficiency (decreased libido or impotence), pulmonary symptoms suggestive of lung cancer, and hyperthyroidism;
  • Physical exam that includes description of palpation of breast, evidence of any alteration of expected secondary sexual characteristics, and testicular, liver, and thyroid examination;
  • Work-up of any abnormal findings;
  • Medical evaluation to exclude endocrinopathy;
  • Pre-op photos;
  • Post-operatively, a pathology report may be requested to confirm the presence of glandular tissue as removal of fatty tissue is considered cosmetic.

For an adult patient with recent onset of progressive breast enlargement, with or without tenderness and mid to late pubertal patients, the following additional information will be used to determine true gynecomastia versus other etiologies. True gynecomastia is defined as the presence of glandular tissue and not fatty tissue:

  • Emphasis on drug-induced gynecomastia (with discontinuance of the drug, if possible, for one month with re-evaluation);
  • Measurement of serum chorionic gonadotropin, testosterone, estradiol, and luteinizing hormone is required when no underlying cause is apparent;
  • If reports result in diagnosis of idiopathic gynecomastia, the condition may be monitored for six months.

Mastectomy for gynecomastia is considered not medically necessary for:

  • Pubertal gynecomastia with tender palpable breast tissue or fatty tissue;
  • Drug related gynecomastia (these may include but not limited to:  androgens and anabolic steroids, oral and topical estrogens, spironolactone, methyldopa, phenytoin, cimetidine, digitalis, psychoactive agents, alcohol, marijuana);
  • Removal of fatty tissue.

The plan will not cover mastectomy for gynecomastia performed by liposuction ONLY.

 

DESCRIPTION OF PROCEDURE OR SERVICE

Gynecomastia is the benign enlargement of the male breast, either due to increased adipose tissue, glandular tissue, fibrous tissue, or a combination of all three. This condition should not be confused with pseudogynecomastia, which is an enlargement of the male breast due to excess fat deposition. Gynecomastia can be attributed to physiologic, pathologic, or pharmacologic causes.  Physiologically in newborns breast development may be associated with galactorrhea. It is also seen with aging and teenage boys. Causes of pathologic gynecomastia may include testicular and pituitary tumors, chronic liver disease, genetic disorders/congenital endocrine conditions (Klinefelter’s disease) and kidney failure.

In adults, it has been suggested that approximately 45-50% of cases are associated with an underlying pathology. Adolescent gynecomastia is considered a normal variation of puberty that rarely persists and typically spontaneously regresses within 18 to 24 months. If adolescents have surgical therapy before completion or at near completion of their puberty, the hormonal imbalance that caused the gynecomastia may cause recurrence. Especially in children and youths, most cases of gynecomastia have no absolute indication for therapeutic intervention, as they are temporary and show a high number of spontaneous remissions.

The most common cause of gynecomastia in the male is puberty. It accounts for more than 65 percent of male breast disorders. The condition may occur in one or both breasts and begins as a small lump beneath the nipple, which may be tender. Gynecomastia during puberty is not uncommon, is self-limiting and usually resolves spontaneously within two years. The etiology appears to be related to an increase in estrogens, a decrease in androgens or some alteration in the estrogen-androgen level. Gynecomastia may also result as a side effect from certain drugs including, but not limited to: estrogens, androgens, spironolactone, digitalis preparations, flutamide, ketoconazole, cimetidine, anabolic steroids, alcohol, amphetamines, and marijuana.

Careful clinical evaluation is warranted to rule out possible pathological etiologies prior to any surgical intervention. When a cause of the gynecomastia is determined and addressed appropriately, spontaneous resolution of the gynecomastia usually occurs over a short period. 

Treatment of gynecomastia involves consideration of the underlying cause. For example, treatment of the underlying hormonal disorder, cessation of drug therapy, or weight loss may all be effective therapies. Gynecomastia may also resolve spontaneously and adolescent gynecomastia may resolve with aging. Prolonged gynecomastia causes periductal fibrosis and stromal hyalinization, which prevents regression of the breast tissue. A variety of surgical techniques have been described as being used to perform mastectomy for gynecomastia, including direct excision, liposuction or a combination of both.

KEY POINTS

This has been updated regularly with searches of the MEDLINE database. The most recent literature update was performed through December 17, 2021.

Summary of Evidence

The medical literature indicates that gynecomastia is due to the stimulated growth of glandular breast tissue and does not significantly affect the disposition of fatty tissue. Therefore, mastectomy for gynecomastia should focus on the removal of glandular tissue underlying the condition. The use of liposuction as a method of mastectomy for gynecomastia has not been sufficiently proven to remove glandular tissue and is not considered an acceptable alternative to standard surgical approaches.

Practice Guidelines and Position Statements

The American Society of Plastic Surgeons

The American Society of Plastic Surgeons (ASPS) issued practice criteria for third-party payers in 2002, which was reaffirmed in 2015. ASPS classified gynecomastia using the following scale, which was “adapted from the McKinney and Simon, Hoffman and Kohn scales”:

Grade I

Small breast enlargement with localized button of tissue that is concentrated around the areola.

Grade II

Moderate breast enlargement exceeding areola boundaries with edges that are indistinct from the chest.

Grade III

Moderate breast enlargement exceeding areola boundaries with edges that are distinct from the chest with skin redundancy present.

Grade IV

Marked breast enlargement with skin redundancy and feminization of the breast.

 

According to the ASPS, in adolescents, surgical treatment for unilateral or bilateral grade II or III gynecomastia may be appropriate if the gynecomastia persists for more than one year after pathological causation is ruled out (or six months if grade IV) and continues after six months if medical treatment is unsuccessful.  In adults, surgical treatment for unilateral or bilateral grade III or grade IV gynecomastia is ruled out and continues after three to four months after pathological causation is ruled out and continues after three to four months of medical treatment that is unsuccessful.  The ASPS also indicates surgical treatment of gynecomastia may be appropriate when distention and tightness cause pain and discomfort.

 

American Society of Andrology

In 2019, the American Society of Andrology, in collaboration with the European Academy of Andrology, released clinical practiceguidelines on gynecomastia evaluation and management.7, Their recommendation related to surgical intervention is as follows:

  • "We suggest surgical treatment only for patients with long-lasting GM [gynecomastia], which does not regress spontaneously orfollowing medical therapy. The extent and type of surgery depend on the size of breast enlargement, and the amount of adiposetissue [weak recommendation, low quality of evidence]."

 

U.S. Preventive Services Task Force Recommendations

Surgery for gynecomastia is not a preventive service.

KEY WORDS

Gynecomastia, mastectomy

APPROVED BY GOVERNING BODIES

This medical policy is not an authorization, certification, explanation of benefits, or a contract. Eligibility and benefits are determined on a case-by-case basis according to the terms of the member’s plan in effect as of the date services are rendered. All medical policies are based on (i) research of current medical literature and (ii) review of common medical practices in the treatment and diagnosis of disease as of the date hereof. Physicians and other providers are solely responsible for all aspects of medical care and treatment, including the type, quality, and levels of care and treatment.

This policy is intended to be used for adjudication of claims (including pre-admission certification, pre-determinations, and pre-procedure review) in Blue Cross and Blue Shield’s administration of plan contracts.

The plan does not approve or deny procedures, services, testing, or equipment for our members. Our decisions concern coverage only. The decision of whether or not to have a certain test, treatment or procedure is one made between the physician and his/her patient. The plan administers benefits based on the member’s contract and corporate medical policies. Physicians should always exercise their best medical judgment in providing the care they feel is most appropriate for their patients. Needed care should not be delayed or refused because of a coverage determination.

As a general rule, benefits are payable under health plans only in cases of medical necessity and only if services or supplies are not investigational, provided the customer group contracts have such coverage.

The following Association Technology Evaluation Criteria must be met for a service/supply to be considered for coverage:

  1. The technology must have final approval from the appropriate government regulatory bodies;
  2. The scientific evidence must permit conclusions concerning the effect of the technology on health outcomes;
  3. The technology must improve the net health outcome;
  4. The technology must be as beneficial as any established alternatives;
  5. The improvement must be attainable outside the investigational setting.

Medical Necessity means that health care services (e.g., procedures, treatments, supplies, devices, equipment, facilities or drugs) that a physician, exercising prudent clinical judgment, would provide to a patient for the purpose of preventing, evaluating, diagnosing or treating an illness, injury or disease or its symptoms, and that are:

  1. In accordance with generally accepted standards of medical practice; and
  2. Clinically appropriate in terms of type, frequency, extent, site and duration and considered effective for the patient’s illness, injury or disease; and
  3. Not primarily for the convenience of the patient, physician or other health care provider; and
  4. Not more costly than an alternative service or sequence of services at least as likely to produce equivalent therapeutic or diagnostic results as to the diagnosis or treatment of that patient’s illness, injury or disease.
