Read this as a base rate, not as your odds

These are decisions about other patients, in one state, that had already been through the plan's own internal appeal and were then sent to an outside reviewer. That population is self-selected toward disputes worth pursuing, so the rate says what happened to cases like this at that stage — not what will happen to a specific claim. It is not medical or legal advice.

Why plans deny bariatric surgery

The supervised weight-management programme does not cover the consecutive months the policy requires.
Documentation of the programme is missing months, or the visits are not with the professional the policy names.
The body-mass threshold is met at some points and not at others in the record.
A required psychological or nutritional evaluation is absent.

What actually carried the cases that won

Failed conservative treatment led here — the only procedure in the corpus where that specific dimension came first — and it means the supervised programme, on the policy's own terms. The overturned records showed consecutive documented months with the professional the policy names. The gaps in the affirmed records were usually calendar gaps, not clinical ones. Reviewers grounded these decisions in the published literature and in clinical guidelines.

What the record showed	Share of overturned decisions
Conservative treatment was documented as failed	40%
A published guideline supported the request	31%
The condition was documented as chronic or long-standing	26%
The severity or urgency was documented	23%
Prior treatment was documented	17%
The diagnosis was confirmed	14%
The functional impact on the patient was documented	3%
Objective findings were documented	3%

Shares are of the overturned decisions and do not sum to 100% — a single decision often rested on more than one, and some rested on none of these.

What the reviewers cited

Peer-reviewed literature — in 46% of the overturned decisions

Specialty-society criteria — in 17% of the overturned decisions

bariatric surgery denials — frequently asked

Is denied bariatric surgery worth appealing?

63% of 56 California independent medical reviews were overturned — a solid majority on a modest sample.

What is the most common defect?

A calendar gap. Policies that require consecutive supervised months will read a missing month as a failure to meet the criterion, however good the clinical record is. Assembling the dated visit history is often the whole appeal.

Does the body-mass threshold have to hold throughout?

Policies differ, and some measure at a specific point. Where the record shows the threshold met and later not met, the appeal has to address which measurement the policy governs by rather than leaving the reviewer to choose.
