Anaphylactic reaction due to peanuts, subsequent encounter

This code signifies a severe, life-threatening allergic reaction (anaphylaxis) specifically triggered by peanut consumption. It indicates that the patient is presenting for follow-up care, management of residual symptoms, or evaluation of long-term effects related to a previously diagnosed peanut-induced anaphylactic event.

Use this code when documenting subsequent visits for a patient who has experienced anaphylaxis due to peanuts. This includes encounters for medication refills, allergy testing after the acute phase, education on allergen avoidance, or management of any lingering complications from the initial reaction.

• Ensure the documentation clearly specifies "anaphylaxis" and "peanuts" as the cause.
• Verify that the encounter is not the initial treatment for the acute anaphylactic episode.
• Consider additional codes for any specific symptoms or complications being addressed during the subsequent encounter.
