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 chemotherapy administration

The regimen is not one the policy recognises for the stage and histology submitted.
The line of therapy is not established in the record for a policy that covers the regimen at a specific line.
The administration setting is disputed — the plan directs the infusion to a lower-cost site.
Supportive-care agents billed alongside are denied as not separately necessary.

What actually carried the cases that won

Prior treatment appeared in 87% of the reversals, guideline support in 40%, and failed conservative treatment in 33%. Reading those together: the reviewers wanted the sequence, dated, with the reason each prior regimen ended, and then a recognised regimen recommendation for the line that follows. Records that summarised the patient as heavily pretreated did not establish a line. Peer-reviewed literature led the authorities, with specialty-society criteria behind it.

What the record showed	Share of overturned decisions
Prior treatment was documented	87%
A published guideline supported the request	40%
Conservative treatment was documented as failed	33%
The severity or urgency was documented	23%
The condition was documented as chronic or long-standing	17%
The diagnosis was confirmed	10%
The functional impact on the patient was documented	7%
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 37% of the overturned decisions

FDA labeling — in 17% of the overturned decisions
Clinical guidelines — in 17% of the overturned decisions
Standard of care — in 7% of the overturned decisions

chemotherapy administration denials — frequently asked

Is a denied chemotherapy claim worth appealing?

The plan prevailed in most of these — 50 of 80 California determinations were upheld, with 30 reversed. Chemotherapy denials survived neutral review more often than they fell, on a base of 80 decisions.

How is the line of therapy established?

As dated events. Regimen, dates, and why each stopped — progression, toxicity or completion. Prior treatment appeared in 87% of the reversals, and a policy that covers an agent at second line will not read a narrative summary as proving this is second line.

What about a site-of-care redirection?

That is a different dispute from whether the regimen is necessary. It turns on whether the patient can safely receive the infusion at the site the plan names, and the record has to speak to that specifically.
