Peanut Immunotherapy (CPB 0968, reviewed 2026-08-21)

Effective date
Not stated in the notice
Identified
Sep 30, 2026

Summary

Aetna considers oral Palforzia (peanut allergen powder-dnfp) medically necessary to mitigate allergic reactions, including anaphylaxis, in members with a confirmed peanut allergy when all initial approval criteria are met, including use with a peanut-avoidant diet, no uncontrolled asthma, no history of eosinophilic esophagitis or other eosinophilic gastrointestinal disease, and age 1 to 17 years for initial dose escalation or age 1 year and older for up-dosing or maintenance. Co-administration of Palforzia with a monoclonal antibody such as omalizumab, and Palforzia for the emergency treatment of allergic reactions, are considered experimental, investigational, or unproven, as are all other indications. The policy also states that the Initial Dose Escalation and the first dose of each Up-Dosing level must be given in a healthcare setting equipped to monitor members and manage anaphylaxis.

What to do

Action · 9 steps
01Billing team: confirm that each Palforzia claim is supported by a confirmed peanut allergy diagnosis by serum IgE or skin prick test, that the record documents use with a peanut-avoidant diet, and that the member's age fits the phase billed (ages 1 to 17 for Initial Dose Escalation, ages 1 year and older for Up-Dosing or maintenance).
02The record also needs to show no uncontrolled asthma and no history of eosinophilic esophagitis or other eosinophilic gastrointestinal disease.
03Z91.010 is the covered ICD-10 code for allergy to peanuts.
04Palforzia has no specific HCPCS code.
05Initial Dose Escalation and the first dose of each new Up-Dosing level must be given under healthcare supervision in a setting able to manage potentially severe allergic reactions, including anaphylaxis, and the source states that the medication must be prescribed by or in consultation with a healthcare professional trained in allergic diseases.
06During Initial Dose Escalation, doses are separated by 20 to 30 minutes of observation, and members must be observed for at least 60 minutes after the last dose.
07The source states that Palforzia should be discontinued if symptoms requiring medical intervention, such as epinephrine use, occur with any dose during Initial Dose Escalation.
08If a member cannot begin Up-Dosing within 4 days, the source says Initial Dose Escalation must be repeated in a healthcare setting.
09Co-administration with omalizumab (J2357) and use for emergency treatment of allergic reactions are listed as experimental, investigational, or unproven.
