Diagnosis Overview

What is .07Xd?
Essential facts and insights about Anaphylactic Reaction Due to Milk and Dairy Products

Key Clinical Considerations:

  • Acute onset of symptoms such as hives, swelling, difficulty breathing, or gastrointestinal distress after exposure to milk or dairy products.
  • Laboratory findings may include elevated serum tryptase levels or specific IgE testing for milk proteins.
  • Physical examination may reveal urticaria, angioedema, wheezing, or hypotension.
  • Imaging is typically not required for diagnosis but may be used to rule out other conditions in severe cases.
  • Severity criteria include the presence of respiratory distress, cardiovascular instability, or gastrointestinal symptoms indicating anaphylaxis.

Clinical Information

Clinical Criteria & Documentation Requirements

  • Document the patient's history of allergic reactions to milk or dairy products, including previous anaphylactic episodes.
  • Use specific terminology such as 'anaphylactic reaction' and 'milk allergy' in the medical record.
  • Examples include: 'Patient experienced anaphylaxis after consuming dairy' or 'History of milk allergy confirmed by testing.'
  • Medical necessity documentation should include the rationale for testing and treatment based on the patient's history and symptoms.
  • Quality measures may require documentation of the patient's allergy status and response to treatment.

Coding Guidelines

Usage Guidelines & Examples

  • Use this diagnosis code when a patient has a confirmed anaphylactic reaction specifically due to milk or dairy products.
  • Do not use this code for non-anaphylactic allergic reactions to milk or for lactose intolerance.
  • Related codes include T78.01 for anaphylactic reaction due to peanuts and T78.02 for anaphylactic reaction due to other nuts.
  • Common coding errors include using this code for mild allergic reactions or misidentifying the allergen.
  • In complex cases, ensure that the specific allergen is documented and that the reaction meets anaphylaxis criteria.

Code Exclusions

Important Exclusions

  • Excluded conditions include lactose intolerance and non-allergic food sensitivities.
  • Alternative codes for excluded conditions include K90.4 for lactose intolerance.
  • Conditions are excluded because they do not involve an immune-mediated response.
  • Common exclusion mistakes include misclassifying lactose intolerance as anaphylaxis.
  • Related but distinct conditions include food protein-induced enterocolitis syndrome (FPIES).

Specialty Focus

Primary Specialty

Allergy and Immunology

Specialty Applications

  • This diagnosis applies to patients with a known allergy to milk or dairy products.
  • Patient populations include children and adults, particularly those with a family history of allergies.
  • Clinical settings include outpatient allergy clinics, emergency departments, and inpatient settings for severe reactions.
  • Specialty-specific applications are relevant in allergy and immunology practices.
  • Treatment contexts include emergency management of anaphylaxis and long-term allergy management.

Coding Complexity

High Complexity

This diagnosis requires careful attention to:

  • Comprehensive clinical documentation
  • Accurate code selection based on clinical criteria
  • Proper exclusion considerations
  • Specialty-specific coding guidelines

Documentation

Documentation Templates

Template 1

Template: 'Patient diagnosed with anaphylactic reaction due to milk based on clinical findings of urticaria and respiratory distress.'

Template 2

Template: 'Clinical presentation consistent with anaphylaxis including hives and difficulty breathing after dairy consumption.'

Template 3

Template: 'Diagnostic criteria for anaphylaxis met as evidenced by elevated tryptase levels and acute symptoms.'

Template 4

Template: 'Treatment plan initiated for anaphylactic reaction with epinephrine administration and observation.'

Template 5

Template: 'Follow-up care for milk allergy including education on avoidance and emergency action plan.'

Billing Information

Billing Considerations

  • Ensure proper documentation for billing
  • Verify code specificity requirements
  • Check for any additional codes needed
  • Review payer-specific guidelines

Common Issues

  • Insufficient clinical documentation
  • Incorrect code selection
  • Missing supporting diagnoses
  • Timing and frequency documentation

Frequently Asked Questions

What documentation is required for this diagnosis?

Detailed documentation of the patient's allergic history, symptoms, and any diagnostic testing results.

How does this differ from similar diagnoses?

This diagnosis specifically refers to anaphylaxis triggered by milk, while other codes may refer to different allergens.

What are common billing considerations?

Ensure that the diagnosis is clearly linked to the services provided, especially in emergency settings.

What procedures are typically associated?

Related CPT codes may include 95115 for allergy testing and 96372 for administration of epinephrine.

Are there any quality reporting implications?

Quality measures may include tracking anaphylaxis management and patient education on allergen avoidance.
