If your surgeon has told you that you need a psychological evaluation before your procedure, you are not in trouble. You are not being screened out. The evaluation exists because the surgeries that require it, bariatric, spinal cord stimulator implantation, organ transplant, gender-affirming, and a few others, have outcomes that depend partly on psychological factors. The evaluation is part of setting you up for the best possible result.

Which surgeries typically require one

  • Bariatric surgery (gastric sleeve, bypass, etc.), required by virtually every accredited bariatric program.
  • Spinal cord stimulator and other neuromodulation implants, required by Medicare and most commercial insurers.
  • Organ transplant (kidney, liver, heart, lung), required by transplant programs.
  • Gender-affirming surgery, often required, sometimes a letter rather than full evaluation.
  • Certain elective fertility and oncology procedures, occasionally requested.

What the evaluation is actually for

The evaluation answers three practical questions:

  • Do you have the cognitive and emotional resources to follow the post-surgical regimen? Bariatric surgery, for example, requires lifelong dietary changes. Spinal cord stimulators require adjusting expectations about pain.
  • Are there active mental health conditions that should be addressed before surgery, or supported during recovery, to reduce risk?
  • What support and follow-up will give you the best outcome?

It is not a pass/fail test. The vast majority of patients are cleared. The evaluation often results in a recommendation for short-term support (therapy, a nutritionist, sleep treatment) before or alongside surgery, not a delay.

What happens during the evaluation

A typical pre-surgical psychological evaluation at Lifespan involves:

  • A clinical interview (60 to 90 minutes): medical history, mental health history, motivation for the surgery, support system, lifestyle factors, expectations.
  • Standardized measures: depression and anxiety screening, sometimes personality and coping assessments depending on the surgery type. Bariatric evaluations often include eating-related measures.
  • Surgery-specific assessment: for spinal cord stimulators, we assess pain catastrophizing, kinesiophobia, opioid use patterns, and treatment expectations. For bariatric, we assess understanding of dietary changes, body image, and history of disordered eating.
  • Feedback and recommendations: a brief report sent to your surgical team within a few business days.

Total clinical time is usually 2 to 4 hours, depending on the procedure. It is one visit, sometimes two.

What you should bring to the appointment

  • A list of current medications and any past or current mental health treatment.
  • The name of your surgeon and the procedure you are being evaluated for.
  • Your insurance card and a copy of the referral if you have one.
  • If applicable, any prior psychological evaluations or therapy records.

Common worries we hear, addressed directly

"Will the report disqualify me?" Usually no. Most evaluations result in clearance. When concerns come up, they typically lead to brief targeted support, not denial.

"Will my surgeon see everything I say?" No. The report sent to your surgical team contains the conclusions and recommendations relevant to surgery, not the full clinical interview. Sensitive content stays in your protected chart.

"What if I have anxiety or depression?" Those are extremely common and almost never disqualify you. They are reasons to make sure you have good support around surgery, not reasons to delay.

"How long until I can have surgery?" Most evaluations result in a clearance letter within one to two weeks of the appointment.

Insurance and payment

Many commercial insurance plans cover pre-surgical psychological evaluations under behavioral health benefits. Medicare covers spinal cord stimulator evaluations. We verify benefits and provide a written quote before scheduling. If we are out-of-network with your plan, we provide a superbill.
