Note: Most Aetna plans exclude coverage of sex change surgery (gender reassignment surgery, transgender surgery) or any treatment of gender identity disorders.  Please check benefit plan descriptions. 

Aetna considers sex reassignment surgery medically necessary when all of the following criteria are met:

1. Member is at least 18 years old; and

2. Member has met criteria for the diagnosis of "true" transsexualism, including:

   • Life-long sense of belonging to the opposite sex and of having been born into the wrong sex, often since childhood; and
   • A sense of estrangement from one's own body, so that any evidence of one's own biological sex is regarded as repugnant; and
   • Wishes to make his or her body as congruent as possible with the preferred sex through surgery and hormone treatment; and
   • A stable transsexual orientation evidenced by a desire to be rid of one's genitals and to live in society as a member of the other sex for at least 2 years, that is, not limited to periods of stress; and
   • Does not gain sexual arousal from cross-dressing; and
   • Absence of physical inter-sex of genetic abnormality; and

   • Not due to another biological, chromosomal or associated psychiatric disorder, such as schizophrenia; and

3. Member has completed a recognized program of transgender identity treatment as evidenced by all of the following:

   • The member has successfully lived and worked within the desired gender role full-time for at least 12 months (so-called real-life experience), without periods of returning to the original gender; and
   • Unless medically contraindicated, member has received at least 12 months of continuous hormonal sex reassignment therapy recommended by a mental health professional and carried out by an endocrinologist (which can be simultaneous with the real-life experience); and
   • A qualified mental health professional* who has been acquainted with the member for at least 18 months recommends sex reassignment surgery documented in the form of a written comprehensive evaluation; and
   • A second concurring recommendation by another qualified mental health professional * must be documented in the form of a written expert opinion**; and
   • Psychotherapy is not an absolute requirement for surgery unless the mental health professional's initial assessment leads to a recommendation for psychotherapy that specifies the goals of treatment, estimates its frequency and duration throughout the real life experience (usually a minimum of 3 months); and
   • For genital surgical sex reassignment, member has undergone a urological examination for the purpose of identifying and perhaps treating abnormalities of the genitourinary tract, since genital surgical sex reassignment includes the invasion of, and the alteraton of, the genitourinary tract (urological examination is not required for persons not undergoing genital reassignment); and
   • Member has demonstrated an understanding of the proposed male-to-female or female-to-male sex reassignment surgery with its attendant costs, required lengths of hospitalization, likely complications, and post surgical rehabilitation requirements of the planned surgery.

* At least one of the two clinical behavioral scientists making the favorable recommendation for surgical (genital and breast) sex reassignment must possess a doctoral degree (e.g., Ph.D., Ed.D., D.Sc., D.S.W., Psy.D., or M.D.). Note: Evaluation of candidacy for sex reassignment surgery by a mental health professional is covered under the member’s medical benefit, unless the services of a mental health professional are necessary to evaluate and treat a mental health problem, in which case the mental health professional’s services are covered under the member’s behavioral health benefit. Please check benefit plan descriptions.

** Either two separate letters or one letter with two signatures is acceptable.

Note: Rhinoplasty, face-lifting, lip enhancement, facial bone reduction, blepharoplasty, liposuction of the waist, reduction thyroid chondroplasty, laryngoplasty or shortening of the vocal cords, which have been used in feminization, are considered cosmetic. Similarly, chin implants, nose implants, and lip reduction, which have been used to assist masculinization, are considered cosmetic.

Transsexualism is "a gender identity disorder in which the person manifests, with constant and persistent conviction, the desire to live as a member of the opposite sex and progressively take steps to live in the opposite sex role full-time."  People who wish to change their sex may be referred to as "Transsexuals" or as people suffering from "Gender Dysphoria" (meaning unhappiness with one's gender).

Transsexuals usually present to the medical profession with a diagnosis of transsexualism, a sophisticated understanding of their condition, and a desired course of treatment, that is, hormone therapy and sex-reassignment surgery.  Due to the far-reaching and irreversible results of hormonal and/or surgical transformational measures, a careful diagnosis and differential diagnosis is absolutely vital to the patient's best interest.  In and of themselves, a patient's self-diagnosis and the intensity of his desire for sex reassignment cannot be viewed as reliable indicators of transsexuality.  A vital part of the long-term diagnostic therapy is the so-called real-life experience, in which the patient lives as a member of the desired sex continually and in all social spheres in order to accumulate necessary experience.  Experience in specialist Gender Identity Units has shown that only about 15% of male transsexuals and 90% of female transsexuals are considered suitable for surgery or still desire it after specialist psychiatric care and a prolonged period of observation used to identify the relatively rare "true" transsexual from the more common "secondary" transsexual.

Hormone therapy and sex-reassignment surgery are superficial changes in comparison to the major psychological adjustments necessary in changing sex.  Treatment should concentrate on the psychological adjustment, with hormone therapy and sex-reassignment surgery being viewed as confirmatory procedures dependent on adequate psychological adjustment.  Psychiatric care may need to be continued for many years after sex-reassignment surgery.  The technical success of sex-reassignment surgery is greater for male-to-female transsexuals than female-to-male transsexuals, and continues to improve as new techniques are developed.  The overall success of treatment depends partly on the technical success of the surgery, but more crucially on the psychological adjustment of the transsexual, and the support from family, friends, employers and the medical profession.

Lawrence and colleagues (2005) stated that male-to-female transsexuals display male-typical category-specific sexual arousal following sex reassignment surgery, and that vaginal photoplethysmography is a promising methodology for studying patterns of sexual arousal in post-operative transsexuals.
