Use when the patient presents with symptoms of an allergic reaction and testing is performed.
Applicable To
- Evaluation of unspecified allergic reactions
Excludes
- Specific allergic reactions
Clinical Validation Requirements
- Documentation of symptoms indicative of an allergic reaction
- Testing performed to identify the allergen causing the reaction
Coding Notes
Ensure symptoms are documented to support the use of this code.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Allergy Testing to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code Z01.82.
Impact
Clinical: Inadequate data for clinical decision-making, Regulatory: Non-compliance with documentation standards, Financial: Potential claim denials
Mitigation Strategy
Use templates to ensure all necessary details are recorded, Train staff on documentation standards
Impact
Reimbursement: Incorrect coding may lead to claim denials., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate data on patient encounters.
Mitigation Strategy
Use T78.40XA for active reactions and Z01.82 for testing without symptoms.
Impact
Using Z01.82 when active symptoms are present
Mitigation Strategy
Educate staff on proper code usage and documentation requirements.
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.
