Getting a letter for top surgery typically involves meeting with a licensed mental health professional who evaluates your readiness and writes a referral. Most surgeons and insurance companies require one letter for chest surgery, and the process can take anywhere from a single session to several weeks depending on the provider. Here’s what you need to know to move through it efficiently.
What the Letter Actually Is
A surgical readiness letter (sometimes called a referral letter) is a document from a qualified mental health professional confirming that you meet the clinical criteria for gender-affirming chest surgery. It serves two purposes: it satisfies the surgeon’s requirements before they’ll schedule your procedure, and it’s typically needed by insurance companies to approve coverage. You’ll need a separate letter for each surgery you pursue, so a top surgery letter is specific to that procedure.
The letter generally documents a diagnosis of gender dysphoria or gender incongruence, confirms that your experience has been marked and sustained over time, notes that any mental health concerns are reasonably well controlled, and states that you have the capacity to give informed consent. It also covers practical readiness factors like your housing stability, support system for recovery (someone to drive you home, help with meals and errands), and any mobility or access needs that might affect your post-surgical care.
Who Can Write the Letter
The letter must come from a licensed mental health professional, not your primary care doctor. Qualified providers include licensed professional counselors, licensed clinical social workers, psychologists, marriage and family therapists, and psychiatrists. The key requirement is that they hold a current license and have training or experience working with transgender individuals. Familiarity with the WPATH Standards of Care is expected.
Your primary care provider or whoever prescribes your hormones (if applicable) may also need to submit a separate letter of support alongside the mental health letter. Check with your surgeon’s office to confirm exactly what they need, since requirements vary by practice and insurer.
What You’ll Need to Qualify
Under the current WPATH Standards of Care (Version 8), the criteria for chest surgery are more straightforward than many people expect. You need:
- Persistent, well-documented gender dysphoria or gender incongruence
- Capacity to consent to treatment after being fully informed of risks and outcomes
- Age of majority in your country (typically 18), with separate guidelines for adolescents
- Any significant mental health concerns reasonably well controlled
One important detail: hormone therapy is not a prerequisite for top surgery. You do not need to have been on testosterone (or any hormones) to qualify. This is a common misconception, but the current standards explicitly state that hormones are not required for chest surgery. Some older provider practices or insurance policies may still reference outdated requirements, so if you’re told otherwise, it’s worth pushing back and citing the current guidelines.
The Evaluation Process
What happens during the assessment depends on the provider. Some therapists who specialize in gender-affirming care can complete the evaluation in one to three sessions. Others, particularly those less experienced with trans patients, may want to see you over a longer period. At multidisciplinary clinics like Mount Sinai’s Center for Transgender Medicine, the process can be condensed into visits over a couple of days, where you meet with a social worker, primary care provider, and behavioral health specialist in coordinated appointments.
During the evaluation, expect the therapist to ask about your gender history, how long you’ve experienced dysphoria, your understanding of the surgery and recovery process, your mental health history, and your support system. This isn’t a test you pass or fail. The therapist is confirming that your decision is informed and that you’re in a stable place to handle a surgical recovery. If you have a diagnosed mental health condition like depression or anxiety, that won’t disqualify you. It just needs to be managed and not actively interfering with your ability to make decisions or recover safely.
Letters must be written within 18 months of surgery, so timing matters. If you get a letter too early and your surgery is delayed, you may need to get an updated one.
Finding an Affordable Provider
Cost can be a real barrier. A private therapy session runs anywhere from $100 to $250 or more without insurance, and if a provider wants multiple sessions before writing a letter, it adds up quickly. Here are several ways to reduce that burden.
The Gender Affirming Letter Access Project (GALAP) maintains a directory of independent clinicians who have pledged to provide gender-affirming care. These providers are licensed in specific states, and many offer telehealth appointments, which broadens your options significantly. The GALAP is not a clinic or health system but a network of individual providers, so you’ll need to contact them directly, verify their licensure in your state, and vet them before scheduling. Their website also offers a “Harm Reduction Guide to Referral Letters” that can help you prepare.
Other options include community health centers with sliding-scale fees, university training clinics where supervised graduate students provide low-cost therapy, and LGBTQ+ health organizations in your area. If you have insurance, call your plan and ask specifically for in-network therapists experienced with gender dysphoria assessments.
Some Surgeons Skip the Letter
A growing number of surgeons use an informed consent model for top surgery, where they conduct their own assessment during the consultation rather than requiring an outside letter. In this model, the surgeon discusses risks, benefits, and alternatives directly with you and documents your verbal or written consent. This approach is more common for top surgery than for genital surgeries, which typically still require two letters.
Research on gender-affirming care shows that clinicians practicing in multidisciplinary clinics are less likely to require a separate mental health assessment, while solo practitioners or those who also perform genital surgeries tend to be more conservative in their requirements. If you want to avoid the letter process entirely, search specifically for informed consent surgeons in your area. Keep in mind, though, that even if a surgeon doesn’t require a letter, your insurance company almost certainly will if you want coverage. So skipping the letter often means paying out of pocket for the surgery itself.
How to Prepare for Your Appointment
Walking into the evaluation prepared can shorten the process considerably. Bring a written summary of your gender history: when you first recognized your identity, how long you’ve experienced chest dysphoria, any steps you’ve already taken (social transition, hormones, binding), and what you understand about the surgery and recovery. If you’ve been seeing a therapist, ask them to forward notes to the evaluating provider ahead of time.
Be ready to discuss your post-surgical support plan. Providers writing these letters are specifically asked to document that you have someone to take you to and from surgery, help with recovery needs like grocery shopping and meal preparation, and that your housing situation is stable with access to a private bathroom. If your support network is limited, think through this in advance and have a plan, even if it means lining up friends, community members, or a post-op recovery service.
If you already have a therapist who knows your history but isn’t qualified or comfortable writing a surgery letter, ask them for a referral to someone who is. They can also send supporting documentation to the new provider, which often speeds up the assessment to a single session.
