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 radiation therapy

The policy treats the requested technique as not necessary where a conventional one is available.
The number of fractions exceeds what the policy allows for the indication.
Planning or image-guidance codes are denied as not separately necessary.
The indication falls outside the policy's enumerated list for the technique requested.

What actually carried the cases that won

Severity and red-flag findings led the overturned decisions — the anatomy at risk, the extent of disease, the reason a conventional technique would not do here. The pattern mirrors proton therapy: a patient-specific reason beats a general claim about the modality. Clinical guidelines and specialty-society criteria were the reviewers' authorities.

What the record showed	Share of overturned decisions
The severity or urgency was documented	95%
A published guideline supported the request	41%
The diagnosis was confirmed	21%
Objective findings were documented	19%
The functional impact on the patient was documented	17%
The condition was documented as chronic or long-standing	12%
Prior treatment was documented	6%
Conservative treatment was documented as failed	5%

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

Clinical guidelines — in 53% of the overturned decisions
Specialty-society criteria — in 42% of the overturned decisions
Peer-reviewed literature — in 29% of the overturned decisions
Standard of care — in 9% of the overturned decisions
FDA labeling — in 3% of the overturned decisions

radiation therapy denials — frequently asked

Is a denied radiation therapy claim worth appealing?

61% of 129 California independent medical reviews were overturned — a solid majority, and notably better than the proton-therapy group, where the same kind of technique dispute went the plan's way more often.

What makes a technique argument work?

Anatomy. The overturned records identified what was at risk and why the conventional plan could not spare it — not that the advanced technique is generally superior.

Are planning and guidance codes appealed separately?

Often they have to be. A denial of the planning or image-guidance code is a distinct determination from a denial of delivery, and an appeal that addresses only the course may leave the denied component untouched.
