Molina bariatric surgery denied: how to appeal

Quick answer

If Molina Healthcare denied your bariatric surgery, you can appeal, and the plan must give you its file and the criteria it used. Filing windows by plan type: 60 days from the notice (Medicaid managed care); at least 180 days (insured and Marketplace plans); 65 days from the notice (Medicare Advantage). The date printed on your denial notice controls; it can only be later than these floors, never earlier.

Why Molina Healthcare denies bariatric surgery

Molina Healthcare is concentrated in Medicaid managed care, with smaller marketplace and Medicare Advantage footprints. Appeal pathways depend heavily on the underlying line of business and the state Medicaid agency that contracts with Molina.

For bariatric surgery specifically: Sleeve gastrectomy, gastric bypass, and revision surgery are denied for unmet criteria far more often than for medical reasons: BMI history, a supervised weight-loss program, a psychological evaluation, or nutrition counseling missing from the file.

The law that controls this appeal

Plans set written criteria, commonly BMI of 40 or more, or 35 or more with a qualifying condition such as type 2 diabetes, sleep apnea, or hypertension, plus documented conservative weight-loss attempts, a psychological evaluation, and a nutrition assessment. Some plans exclude bariatric surgery entirely, which is a benefit exclusion rather than a medical-necessity decision. Medicare covers bariatric surgery for beneficiaries meeting its criteria under National Coverage Determination 100.14. Criteria must be disclosed on request (29 CFR 2560.503-1(m)(8); 45 CFR 147.136).

Molina Healthcare appeals: the rule, the deadline and the next level, by plan type

Which row applies depends on the plan you hold, not on Molina Healthcare's brand. Your ID card, the Summary Plan Description and the denial letter say which.

Plan type	Rule that governs	File your appeal within	The plan must answer	If the plan says no again
Medicaid managed care plan A Medicaid plan run by the carrier under a state contract. The card says Medicaid, Medi-Cal, STAR, HealthChoice or your state's programme name.	42 CFR Part 438, Subpart F (plan appeals) and 42 CFR Part 431, Subpart E (state fair hearings).	60 calendar days from the date on the notice of adverse benefit determination to request the plan's appeal (42 CFR 438.402(c)(2)(ii)). State fair hearing: within 120 calendar days of the plan's appeal decision (§ 438.408(f)(2)).	Standard appeal: 30 calendar days. Expedited: 72 hours (42 CFR 438.408(b)).	A state fair hearing after the plan's single level of appeal (§ 438.402(b)); some states add an external medical review. Benefits continue during the appeal if you ask within 10 calendar days of the notice (§ 438.420).
Fully insured employer, individual or Marketplace plan The carrier holds the risk and is licensed in your state. Small employers and almost all individual and HealthCare.gov plans.	45 CFR 147.136 (Public Health Service Act § 2719), which applies the 29 CFR 2560.503-1 procedures and adds state external review; state insurance law on top.	At least 180 days from the denial (45 CFR 147.136(b); 29 CFR 2560.503-1(h)(3)(i)).	Urgent care: 72 hours. Pre-service: 30 days. Post-service: 60 days. Prior-authorization decisions by Marketplace issuers from 2026: 72 hours expedited, 7 calendar days standard (CMS-0057-F).	External review through your state's process, or the federal process where the state has none, generally within 4 months of the final internal denial (45 CFR 147.136(c), (d)). The state insurance department and its Consumer Assistance Program take complaints.
Medicare Advantage (Part C) A private plan that replaces Original Medicare. The card says Medicare Advantage, HMO, PPO or PFFS.	42 CFR Part 422, Subpart M (§§ 422.560 to 422.634). Coverage decisions must follow Original Medicare rules (42 CFR 422.101).	65 calendar days from the date on the denial notice to request the plan's reconsideration (42 CFR 422.582, as amended effective 1 January 2025).	Expedited: 72 hours. Standard pre-service: 30 days (7 days for Part B drugs). Payment: 60 days (42 CFR 422.590).	If the plan does not fully reverse itself it must send the case to the Independent Review Entity on its own (42 CFR 422.592); then an ALJ hearing when the amount in controversy meets the annual threshold, the Medicare Appeals Council and federal court. State external review does not apply.

Medicaid managed care plan

What you can demand. Free copies of the case file, medical records and the criteria used, before and during the appeal (42 CFR 438.406(b)(5)). Children under 21 have EPSDT rights to medically necessary care (42 U.S.C. 1396d(r)(5)).

How to open the appeal. Cite 42 CFR 438.402 and 438.406(b)(5): request the case file and the criteria, ask for continued benefits within 10 days, and reserve the state fair hearing.

Fully insured employer, individual or Marketplace plan

What you can demand. The plan must give you the claim file, the criteria it applied and any new evidence or rationale before the final decision, free of charge (45 CFR 147.136(b)(2)(ii)(C); 29 CFR 2560.503-1(h)(2)(iii)).

How to open the appeal. Cite 45 CFR 147.136 and 29 CFR 2560.503-1: request the claim file and the criteria, note the decision clocks, and name the state external-review right.

Medicare Advantage (Part C)

What you can demand. The plan may not apply internal criteria that are more restrictive than Medicare's national and local coverage determinations, and must decide medical necessity on your individual circumstances (42 CFR 422.101(b), (c)). You can ask for the case file and the criteria used.

How to open the appeal. Cite 42 CFR 422.582 and 422.101(c): the plan must decide on your individual circumstances under Medicare coverage rules, and must forward an unfavorable reconsideration to the IRE itself.

What Molina Healthcare denies for bariatric surgery

The bariatric surgery services most often denied:

Sleeve gastrectomy or Roux-en-Y gastric bypass
Revision or conversion surgery after weight regain or complications
Surgery for patients with BMI between 35 and 40
Adolescent bariatric surgery
Surgery when the plan has a bariatric exclusion

Why bariatric surgery claims get denied

Supervised weight-loss program not completed or not documented month by month
Psychological evaluation or nutrition consult missing
Comorbidity not documented in the record
Plan excludes weight-loss surgery as a benefit

The Molina Healthcare appeal process

Appeal levels: Plan internal appeal, then state Medicaid fair hearing for Medicaid lines. Marketplace: internal then federal external review. Medicare Advantage: federal 5-level ladder.

Carrier timing: Medicaid filing windows are state-specific, commonly 60-120 days from the action notice. Continuation-of-benefits typically requires filing within 10 days. Marketplace: 180 days internal, 4 months external.

Bariatric surgery timing: Internal appeal: at least 180 days to file for commercial and employer plans; pre-service decisions within 30 days (29 CFR 2560.503-1). Medicare Advantage: 65 days to request reconsideration. External review within 4 months of the final internal denial for ACA-covered plans.

What we know about Molina Healthcare: Molina appeals are most often won at the state fair-hearing stage. We preserve continuation-of-benefits where the timing permits and brief the case to the state's administrative law judge.

Common Molina Healthcare denial patterns for bariatric surgery

State Medicaid fair-hearing escalation. Molina Medicaid denials must first run through the plan's internal grievance and appeal process. After plan-level denial, the member has the right to a state Medicaid fair hearing, a separate administrative track that frequently overturns prior-auth and medical-necessity denials.
Continuity-of-care protections. Medicaid rules generally require continuation of previously authorized services pending the outcome of a timely-filed appeal. Members who file within the state's continuation window (often 10 days from the action notice) preserve services during the appeal.
EPSDT-based denials in pediatric cases. For Molina members under 21, federal EPSDT (Early and Periodic Screening, Diagnostic, and Treatment) requirements broaden coverage beyond the adult benefit. Many pediatric denials reverse on appeal once the EPSDT framework is cited.

How to win your Molina Healthcare bariatric surgery appeal

Strategy for bariatric surgery: Request the plan's bariatric policy. Assemble the BMI history from every visit, the dated notes from the supervised program, the psychological evaluation, and the nutrition assessment, and index them to each criterion. If the denial is a benefit exclusion, check the plan document; an exclusion is appealed on the plan language, not on medical necessity, and external review may not be available. For revision surgery, document the complication or the anatomic failure, since criteria differ from first surgery.

Filed against Molina Healthcare, that strategy rides on this procedural spine:

Procedural-rights anchor. Cite 42 CFR 438.402 and 438.406(b)(5): request the case file and the criteria, ask for continued benefits within 10 days, and reserve the state fair hearing. If your Molina Healthcare coverage is a different plan type (Fully insured employer, individual or Marketplace plan, Medicare Advantage), use that row of the table above instead; the rule and the deadline change with the plan, not the carrier.
Criteria-disclosure demand. Molina Healthcare frequently denies on "not medically necessary" without disclosing the clinical criteria applied. Once disclosed, those criteria become the rebuttal map.
Controlling-standard citation. Plans set written criteria, commonly BMI of 40 or more, or 35 or more with a qualifying condition such as type 2 diabetes, sleep apnea, or hypertension, plus documented conservative weight-loss attempts, a psychological evaluation, and a nutrition assessment. Some plans exclude bariatric surgery entirely, which is a benefit exclusion rather than a medical-necessity decision. Medicare covers bariatric surgery for beneficiaries meeting its criteria under National Coverage Determination 100.14. Criteria must be disclosed on request (29 CFR 2560.503-1(m)(8); 45 CFR 147.136).
Treating-provider attestation. A letter from the treating physician addressing each criterion in Molina Healthcare's own policy language. This is the single strongest evidentiary element.
Requested action. A specific demand to reverse the bariatric surgery denial and approve the service, not a general "please reconsider."

Documents you'll need for your Molina Healthcare bariatric surgery appeal

The denial letter naming the criterion not met
BMI and weight history from every visit in the policy period
Supervised weight-loss program notes with dates
Psychological evaluation and nutrition assessment
Records documenting comorbidities (labs, sleep study, blood pressure)

What a bariatric surgery appeal can recover

Typical recovery for bariatric surgery cases runs Bariatric procedures are high-cost hospital surgeries; the amount at stake is the plan's allowed amount for the surgery and the hospital stay.. The exact figure depends on the specific service and your plan's contracted rates.

Molina Healthcare bariatric surgery appeals: frequently asked questions

Molina Healthcare says I did not complete a supervised diet. I did. What now?

The plan needs dated notes from each month of the program, not a summary letter. Gather the visit notes and index them to the policy's requirement in the appeal.

My Molina Healthcare plan excludes bariatric surgery. Can I appeal?

You can appeal on whether the exclusion applies to your procedure and whether the plan document says what the denial says. An exclusion is not a medical-necessity decision, and independent external review is generally not available for it.

What BMI does Molina Healthcare require?

Most policies use 40 or more, or 35 or more with a qualifying condition. The exact figures are in the plan's bariatric policy, which you can request in writing.

Is revision surgery covered by Molina Healthcare?

Often, when there is a documented complication or anatomic failure of the first procedure. Weight regain alone is treated differently by different policies. Get the policy and document the medical reason.
