CodeDescriptionWhen to UseKey Documentation
Z88.6Allergy status to analgesic agentUse when a patient has a confirmed allergy to aspirin or other analgesic agents.
  • Documented history of hypersensitivity reaction to aspirin
  • Positive aspirin challenge test
T39.015AAdverse effect of aspirin, initial encounterUse when documenting an adverse effect of aspirin, such as anaphylaxis or urticaria.
  • Documented adverse reaction to aspirin
  • Clinical symptoms consistent with drug reaction

Clinical Decision Support

Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Adverse effect of aspirin, initial encounter

T39.015A
Use when documenting an adverse effect of aspirin in conjunction with Z88.6.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Aspirin Allergy to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code Z88.6.

Impact

Clinical: Leads to incorrect allergy status documentation., Regulatory: Non-compliance with ICD-10 coding guidelines., Financial: Potential claim denials due to incorrect coding.

Mitigation Strategy

Verify the correct code for analgesic allergies., Educate staff on code differences.

Impact

Reimbursement: Incorrect coding can lead to improper billing and potential denial of claims., Compliance: Misclassification may lead to non-compliance with coding standards., Data Quality: Affects the accuracy of patient records and data analytics.

Mitigation Strategy

Differentiate between true allergic reactions and non-allergic adverse effects.

Impact

Inadequate documentation of allergy details can lead to audit issues.

Mitigation Strategy

Ensure comprehensive documentation of allergy reactions and validation methods.

Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.

Specialty: Cardiology

Required Elements

  • Allergy status
  • Reaction details
  • Validation method
  • Desensitization protocol

Example Documentation

Allergy Status: [ ] No known drug allergies [✔] Aspirin allergy (Z88.6) Reaction: Anaphylaxis (T78.2XXA) in 2023 after 325mg ASA Validation: Positive oral challenge (3/2024, 100mg dose) Desensitization: Completed per Scripps protocol (650mg tolerated) Current ASA Use: 81mg daily without reaction Cross-Reactivity: Avoid all NSAIDs except acetaminophen

Examples: Poor vs. Good Documentation

Poor Documentation Example
Allergic to aspirin.
Good Documentation Example
Patient developed generalized urticaria, angioedema, and wheezing within 30 minutes of 81mg aspirin ingestion. Aspirin challenge positive. Allergy confirmed by immunology.
Explanation
The good example provides specific reaction details, timing, and validation method, which are essential for accurate coding and clinical management.
