Cost of Bypass With Insurance


  • $3,500 average out-of-pocket costs, depending on your insurance plan

1. United States: Covered If Your Plan Includes Bariatric Surgery

In the U.S., gastric bypass is covered under any plan that includes weight loss surgery.

How Do You Know If Your Insurance Includes Weight Loss Surgery?

It varies based on how you get your health insurance:

  • Individual/Family Plans & Small Group Plans (under 50 employees) – Obamacare requires that many states cover weight loss surgery.
  • Large Group Plans (50+ employees) – it is 100% up to the company whether the chosen benefits plan includes bariatric surgery. Ask someone in the HR department or contact your insurance company to see whether it’s covered.
  • Medicare & Medicaid – both of the federally sponsored plans cover gastric bypass surgery, but not all surgeons accept Medicare and Medicaid.

If Your Policy Covers It: Ask for a Free Insurance Check

Most surgical practices will check your insurance benefits for free. Importantly, they’ll normally do it quickly since they have a staff experienced in dealing with insurance companies.

Instead of doing your own research, reach out to local surgeon’s office to check your insurance benefits.

Contact a surgeon for a free insurance check.

The below are average out-of-pocket gastric bypass costs if you have insurance:

  • HMO: $1,475
  • PPO: $2,542
  • POS: $2,270
  • High-Deductible Health Plan: $1,901

See below for assumptions:

  • Zero dollars paid towards your calendar year deductible for other services
  • The were calculated with special formulas that are based off of average plan designs from Kaiser Family Foundation’s Annual Employer Health Benefits Survey (1)

If Your Policy Does NOT Cover It: Seek Partial Coverage

You can likely get some of the costs associated with weight loss surgery paid for by insurance even if you have plan exclusion for bariatric surgery. Whether some of the costs are covered turns on how your medical team submits the claims to the insurance company.

For example, there are a lot reasons unrelated to weight loss surgery why your doctor might request:

  • Cardiology exam
  • Lab work
  • Medically supervised diet program
  • Psychological exam
  • Sleep study

Since is possible or likely that the above was ordered for a reason other than weight loss surgery, the costs can be covered by insurance. If your doctor submits one of these claims using a weight loss surgery CPT code (Current Procedural Terminology Code), your insurance is unlikely to cover it. But if your doctor uses a general CPT code, it likely will be covered.

We assure you that the most upstanding doctors do this. It’s an ethical option because these types of tests and can be beneficial to your health whether or not you end up having weight loss surgery.

The U.S. Insurance Approval Process

Getting your insurance company to approve your gastric bypass surgery takes between 1 and 12 months. Below are the steps:

  1. You meet the body mass index (BMI) requirements and that fact is documented by your doctor:
    • BMI of 40+ –OR–
    • BMI above 35 with one or more of:
      • Clinically significant obstructive sleep apnea
      • Coronary heart disease
      • Medically refractory hypertension
      • Type 2 diabetes mellitus
      • Other obesity-related health issues
  2. Complete three to seven months of a medically supervised diet program in succession.
  3. Book an appointment with your chosen weight loss surgeon for a consultation.
  4. Schedule an appointment with your regular doctor (PCP) so you can get a medical clearance letter.
  5. You’ll need to book a psychiatric exam to get a clearance letter for your mental health.
  6. Book an appointment with a Registered Dietitian for your nutritional evaluation.
  7. Your insurance company will have you send them:
    • Everything you received in steps 1 – 6 above
    • A history of health issues that stem from suffering from obesity
    • Additional problems caused by your weight and any treatment attempts
  8. You’ll hear back from your insurance company in less than a month.
  9. Your insurance company will mail you an approval or denial:
    • If it’s a yes, your weight loss surgeon’s office will call you to get you on the schedule
    • If it’s a no, you can try and appeal the denial.

Your chosen surgical practice can do nearly all of this for you. It’s likely that all the required experts are part of the staff (registered dietitian, psychiatrist, bariatric coordinator, etc.).

Cost Without Insurance


  • Total Cost: $24,000, on average
  • Loan Payment: $556/month, on average
  • Discounts & Tax Savings: Usually available

The average cost of gastric bypass without insurance is $24,300, although this varies widely by surgeon. If you don’t have insurance and ask a surgeon for a gastric bypass quote, you will get one of 3 responses:

  • No Self-Pay Option – these are few and far between – most surgeons readily accept self-pay patients.
  • Partial Quote – some surgeons will respond with only the fees they directly control: the surgical fees. Due to the fact that they don’t know the exact amount of some fees in advance (such as hospital fees). However, most will furnish you with contact information so you can call the hospital and figure out the total cost of your surgery.
  • All-Inclusive Packages – many surgeons will have an “all-inclusive” cost for to share. This is just what it sounds like: a detailed description of everything covered by the cost-quote the surgeon provides.

1. How to Get Weight Loss Surgery Insurance in the U.S.

If your benefits package doesn’t currently include coverage for gastric bypass surgery there are two ways to get it:

  • You may be able to get covered by a plan that requires weight loss surgery be an included benefit under The Affordable Care Act (“Obamacare”). See the Obamacare page for more information.
  • Request that your place of work add it to the current benefits package. If your current employer has more than 50 employees, the employer gets to make the decision on whether weight loss surgery is covered. It makes good financial sense for the company to include bariatric surgery. You can click here to find specific statistics and information to share with the decision-makers in your Human Resources department.

2. Discounts: 6 Discounts to Ask Your Surgeon About

Ask your surgical center if any of the below are available to you:

  • Self-Pay Discounts. Make sure you ask about a possible discount for cash pay!
  • Other Discounts. If you the cash to pay all of your out-of-pocket costs up front, some surgical offices will provide a discount.
  • Same Surgeon, Different Hospitals. This might surprise you, but the hospital fees are always the largest portion of the bill for weight loss surgery. Like anything, some hospitals charge more than others. Be sure to ask your surgeon if he or she is using the lowest-cost location suitable for their needs.
  • Complications. It’s possible you could experience a complication during your procedure. Ask your doctor who foots the bill if that happens. Look at your cost quote carefully to see whether it falls on the surgeon or on you.

Cost Vs. Remaining Obese


  • The average patient saves $11,000 per year after year 2, post-surgery

$24,300 (the average cost of gastric bypass surgery without insurance) is a lot of money, but it’s a small number when compared to the lifelong medical costs of remaining obese.

Beginning in Month-13 post-surgery, people that paid for bariatric surgery out-of-pocket (i.e., insurance didn’t cover anything) save about $900 a month when compared to the average cost of remaining obese (2). Said another way, it’s about $11,000 you’ll “save” every year. Just reducing the number of prescription drugs you’ll take saves, on average, $3,000 or more each year (3).

Stated simply, approximately 21 months after you have surgery you will “break even” and be able to spend $11,000 less on your healthcare expenses each year.
