Clinical Definition

Anaphylactic reaction due to food is a severe, potentially life-threatening systemic allergic response that occurs rapidly after exposure to a food allergen. The reaction typically involves multiple organ systems and can cause respiratory distress, cardiovascular collapse, and shock.

Documentation Requirements

• Acuity

  • Must specify "anaphylactic" or "anaphylaxis"

  • Document if initial or subsequent encounter

  • Note if this is a recurring condition

• Causative Agent

  • Specific food trigger must be documented

  • If multiple foods, list all triggers

  • Note if trigger is confirmed or suspected

• Clinical Manifestations

  • Document at least TWO system involvement:

    • Respiratory (bronchospasm, stridor)

    • Cardiovascular (hypotension)

    • Cutaneous (urticaria, angioedema)

    • Gastrointestinal (vomiting, diarrhea)

• Treatment

  • Document epinephrine administration

  • Note any additional interventions

  • Include treatment response

Scribing.io Automation

The AI scribe automatically flags key phrases like "anaphylaxis," "epinephrine administered," and "food trigger" to ensure proper coding. It identifies system involvement by recognizing terms like "stridor," "hypotension," or "urticaria" and prompts for additional documentation if only one system is mentioned. The system also maintains a running list of documented food allergens for the patient's record.
