Source review: November 2, 2026. Public policies can change. This page does not check member benefits.
Anthem guideline CG-SURG-83 lists sleeve, Roux-en-Y bypass, adjustable band, BPD/DS, SADI-S and ESG among procedures that may be considered medically necessary under its stated criteria. Anthem says contract language, law and medical policy take precedence, and individual plans may choose whether to adopt a guideline.
Anthem and Elevance bariatric coverage: start with the exact product
This page interprets a named public source: Anthem Clinical UM Guideline CG-SURG-83, published December 18, 2025. “Named in a clinical policy” means that the procedure appears in the document under conditions, not that any member has a covered bariatric benefit or is approved for surgery. “Not established” means this review did not find a reliable nationwide procedure answer from the cited source. “Not medically necessary” is used only where the named document explicitly says so for its defined line of business. A Medicare Advantage or Medicaid card issued by the same company may use a different policy.
The cited adult guideline names procedure, age, BMI, comorbidity and evaluation criteria. The word “guideline” is consequential: it is not proof that a particular Anthem or Elevance affiliate adopted the document or that a member has a bariatric benefit. Ask the number on the card for the exact policy and utilization-review path.
Which procedures are named, limited or unresolved?
The labels below apply only to the cited source and its stated product scope. They are not promises of payment. A procedure may be performed in different ways or billed with different codes; the clinical team should identify the exact operation before any request.
| Procedure | What the cited source establishes |
|---|---|
| Sleeve gastrectomy | Named in the cited clinical policy as potentially medically necessary when its criteria are met. This is not a member benefit determination. |
| Roux-en-Y gastric bypass | Named in the cited clinical policy as potentially medically necessary when its criteria are met. This is not a member benefit determination. |
| Adjustable gastric band | Named in the cited clinical policy as potentially medically necessary when its criteria are met. This is not a member benefit determination. |
| BPD/duodenal switch | Named in the cited clinical policy as potentially medically necessary when its criteria are met. This is not a member benefit determination. |
| SADI-S | Named in the cited clinical policy as potentially medically necessary when its criteria are met. This is not a member benefit determination. |
| Endoscopic sleeve gastroplasty (ESG) | Named in the cited clinical policy as potentially medically necessary when its criteria are met. This is not a member benefit determination. |
If a procedure is not established here, do not conclude that it is covered or excluded. Ask for the current procedure-specific written policy. Revisions, conversions and complication care often have separate criteria from first-time surgery. An authorization for one operation, hospital or date should not be assumed to authorize a different one.
Questions to ask Anthem and Elevance
- What is the exact product and line of business on my member card, and does it include a bariatric surgery benefit? Please identify the benefit section or exclusion in writing.
- Which current medical policy applies to the specific operation my surgeon proposes, including any revision or endoscopic procedure?
- What BMI, health conditions, prior treatment and preoperative evaluations must be documented? Is a nutrition or behavioral-health review required?
- Do the surgeon, hospital, anesthesia group and follow-up providers participate in my network? Is an exception process available if they do not?
- Who submits prior authorization, what documents are missing, how long is the decision valid, and how will I obtain the written approval or denial?
- What deductible, coinsurance and separately billed services could remain after approval?
Keep the date, representative name and call reference number. Ask the surgeon’s office for the exact operation name and planned facility. If the plan year changes before surgery, have the office recheck the benefit, policy and authorization. A verbal answer alone does not settle a claim.
If a request is denied, compare the denial reason with the actual benefit and policy. A missing document, clinical criterion, exclusion and network problem have different remedies. Request the cited policy and appeal deadline, then coordinate any clinical appeal with the treating team. Do not submit member identifiers or medical records to this site.
