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 general anesthesia

The policy treats the procedure as one ordinarily done under local or moderate sedation.
Anesthesia for a dental or imaging procedure is denied absent documented behavioural or medical necessity.
The units billed exceed what the policy allows for the documented time.
The technique is denied because the record does not identify a patient-specific risk factor.

What actually carried the cases that won

This is a category where the plan's position held two times in three, and the reversals shared a discipline: they identified the patient, not the procedure. A documented airway concern, a comorbidity, an age or developmental factor, a prior failed attempt under sedation. General statements about patient comfort or standard practice did not carry a case. Where the underlying procedure was itself authorised, saying so plainly removed the plan's easiest reason to look no further.

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.

general anesthesia denials — frequently asked

Is a denied anesthesia claim worth appealing?

Two out of three anesthesia denials survived review: 51 upheld and 24 reversed across 75 California determinations. Anesthesia denials survived neutral review more often than not.

What carried the reversals?

A patient-specific factor. An airway finding, a comorbidity, a developmental or behavioural factor, or a documented failure under lighter sedation — rather than an argument about how the procedure is usually done.

Are unit denials the same dispute?

No. A units denial is a documentation and time question answered with the anesthesia record, not a necessity question, and it is appealed on different ground.
