Health Care Provider Letters

Letters from Health Care Providers

Además de la letter you send to your insurance asking for your transition-related procedure to be pre-approved, your doctor or health care provider should also submit a letter explaining why the treatment is medically necessary a sus necesidades. Your doctor can also include medical documentation about your diagnosis and course of treatment.


Your insurance plan might have specific instructions about the type of medical documentation you need to provide or about the doctor who can provide the letter. For example, some insurance plans require you to provide letters from two doctors, or require a letter from a doctor with a specific type of accreditation (such as a mental health provider). Some insurance plans require specific information, like how long ago you were diagnosed with gender dysphoria or what treatments you’ve received in the past.

You should check your member handbook to make sure that your provider letter meets all the requirements. You should also send your plan policy to your provider so they are aware of the areas their letter will have to address.


Provider letters should typically include:

  • A statement that, in the doctor’s professional opinion, the treatment is medically necessary and the appropriate step in the course of care for the patient’s gender dysphoria. Some plans also require the provider to include codes for specific treatments or diagnosis. 
  • A brief description of the patient’s history of care. This can include, for example, how long they have been a patient of the provider writing the letter, when and by whom they were diagnosed with gender dysphoria, the symptoms of gender dysphoria that they are exhibiting, how long they have been living according to their gender identity, and what transition-related treatments they have received so far.
  • An explanation of why this procedure is medically necessary for this patientIt is recommended that the letter refer to the criteria in the World Professional Association for Transgender Health’s most recent Estándares de cuidado, and demonstrate why the patient meets those criteria. The letter can also discuss the positive impacts that undergoing the procedure is expected to have on the patient’s health and the negative impacts that not receiving the treatment would likely have. In some cases, the letter should also discuss why other treatments that the patient has already received, like counseling, hormone therapy, or previous surgeries, have not fully resolved the patient’s gender dysphoria.
  • Relevant medical research. If possible, the letter should refer to studies demonstrating the effectiveness and medical necessity of the specific treatment that the patient is seeking. The letter can also refer to guidelines and statements by medical organizations that recognize that transition-related treatments for gender dysphoria generally are necessary and effective and that the World Professional Association for Transgender Health (WPATH) Estándares de cuidado provide the established standards of care for gender dysphoria. The letter can also refer to WPATH’s specific 2016 guidance on the medical necessity of coverage for treatment for gender dysphoria en los EE.UU. y WPATH’s recommended benefits policy document. See below for examples of studies and statements that can be cited in a letter or included as supporting documentation.
  • If appealing a denial, the reason why the denial was incorrect (we recommend consulting a lawyer or clinic for assistance with any appeal): If the letter is being provided to appeal a denial that has already happened, it should quote the reason given in the denial letter and directly address why that reason is inappropriate. Sometimes, the denial will happen because the plan excludes a particular procedure (for example, facial feminization surgery or nipple reconstruction). In these cases, it will be particularly important to discuss about why that exclusion should not apply in the case of this particular patient, and why this treatment is medically necessary to treat the patient’s gender dysphoria. WPATH’s Estándares de cuidado and guidance on medical necessity, referenced above, might be particularly helpful in these cases.
  • Health care provider’s credentials and contact information. The letter should include the doctor’s or health care provider’s licensing number, accreditation, and contact information in case more information is needed. It can also include information about the provider’s experience treating patients with gender dysphoria.
