Medicare and Lap-Band care

Medicare covers laparoscopic adjustable gastric banding, along with gastric bypass and some other operations, for people with a body mass index (BMI) of 35 or more, at least one obesity-related condition, and earlier medical treatment for obesity that did not work. Medicare Advantage plans must cover the same medically necessary services but may require prior approval. This reflects the rules as of October 2026.

What Medicare's national rule covers

Medicare's coverage of weight-loss surgery is set by National Coverage Determination (NCD) 100.1 from the Centers for Medicare & Medicaid Services (CMS). The current version took effect on September 24, 2013. It covers these operations when all three conditions are met:

open or laparoscopic Roux-en-Y gastric bypass
open or laparoscopic biliopancreatic diversion, with or without duodenal switch
laparoscopic adjustable gastric banding

The three conditions are a BMI of at least 35, at least one co-morbidity (another condition) related to obesity, and previous unsuccessful medical treatment for obesity. CMS states that type 2 diabetes counts as a co-morbidity for this purpose. For the stand-alone laparoscopic sleeve gastrectomy, the NCD leaves coverage to the regional Medicare Administrative Contractors (MACs) for people who meet the same criteria.

What it does not cover

The NCD states that treatments for obesity alone remain non-covered. It lists these as nationally non-covered:

open adjustable gastric banding
open sleeve gastrectomy
open or laparoscopic vertical banded gastroplasty
intestinal bypass surgery
gastric balloon for treatment of obesity

Medicare.gov adds that Medicare does not pay for transportation to a bariatric surgery center. Earlier versions required surgery at a certified bariatric facility, but CMS removed that requirement for services on or after September 24, 2013.

Band adjustments, removal and revision

The NCD describes the adjustable band and how it is adjusted by adding or removing saline through a port. Its text does not set separate rules for fills, band removal, repair of a complication, or conversion to another operation. Those services are reviewed for medical necessity like other surgery, by your Medicare contractor or, in Medicare Advantage, by your plan.

In practice, the documentation that matters is the same as for any insurer: the operative report, imaging that shows the problem, and notes about your symptoms. Our page on insurance for band removal and revision explains how insurers sort complication cases from weight-regain cases.

Original Medicare and Medicare Advantage

Medicare.gov explains the difference this way:

	Original Medicare	Medicare Advantage
What is covered	Most medically necessary services	Must cover all medically necessary services Original Medicare covers
Prior approval	In most cases not needed	May be needed for certain services
Doctors	Any provider who accepts Medicare	May need to use the plan's network for non-emergency care
Specialist referral	Usually not needed	May be needed

For costs, Medicare.gov says it is hard to predict them in advance. Your share depends on your Part A and Part B deductibles, other insurance, and whether your doctor accepts assignment.

Second opinions and GLP-1 medications

Medicare Part B covers a second opinion before medically necessary surgery that is not an emergency. After the Part B deductible, you pay 20% of the Medicare-approved amount. Medicare also covers a third opinion if the first two differ. See our page on getting a second opinion.

For medication, CMS runs a temporary Medicare GLP-1 Bridge from July 1, 2026, through December 31, 2027. According to Medicare.gov, it is for people with Part D drug coverage, aged 18 or older, who meet set BMI and health criteria. It covers Foundayo, Wegovy and the Zepbound KwikPen for a $50 copay per monthly supply, with prior authorization. People with type 2 diabetes, moderate to severe sleep apnea or fatty liver disease are excluded, because their Part D plan may cover GLP-1 drugs for those conditions. See GLP-1 medications with a Lap-Band.

Frequently asked questions

Does Medicare cover a new Lap-Band in 2026?

NCD 100.1 still lists laparoscopic adjustable gastric banding as covered when you have a BMI of 35 or more, an obesity-related condition and a history of unsuccessful medical treatment. Open banding is not covered. Whether a band is the right operation for you is a separate medical question; see who is a candidate.

Am I too old for bariatric surgery under Medicare?

The NCD's criteria are BMI, an obesity-related condition and prior treatment; they do not include an age cut-off. The 2022 ASMBS/IFSO guidelines say there is no upper age limit for weight-loss surgery, and that older adults should be assessed carefully for frailty and other conditions.

Do I need to go to a certified bariatric center for Medicare to pay?

Not under the current national rule. CMS removed the facility certification requirement for services on or after September 24, 2013. A Medicare Advantage plan may still limit you to its own network of surgeons and hospitals for non-emergency care, so check with your plan before scheduling.

I have a Medicare Advantage plan. Who decides on my band removal?

Your plan does, using Medicare's coverage rules as the minimum. Medicare.gov says Advantage plans must cover all medically necessary services Original Medicare covers, but may require prior approval and in-network providers. Ask the surgeon's office to request authorization, and keep copies of what is sent.
