| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| T78.2XXA | Unspecified anaphylactic shock, initial encounter | Use when the trigger for anaphylaxis is unknown or not documented. |
|
| T88.6XXA | Anaphylactic shock due to adverse effect of drug, initial encounter | Use when anaphylaxis occurs due to a correctly administered drug. |
|
| T80.52XA | Anaphylactic shock due to serum, initial encounter | Use when anaphylaxis is directly linked to serum administration. |

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

Primary ICD-10-CM Codes for anaphylactic reaction
Decision Criteria
clinical Criteria
- Two or more organ systems involved without identifiable trigger.
Applicable To
- Anaphylaxis of unknown origin
Excludes
- Anaphylactic shock due to adverse effect of drug (T88.6XXA)
Clinical Validation Requirements
- Absence of identifiable trigger despite history review
- Involvement of two or more organ systems
Code-Specific Risks
- Risk of under-documentation if trigger is not explored thoroughly.
Coding Notes
- Ensure thorough documentation of symptoms and lack of identifiable trigger.
T88.6XXA - Anaphylactic shock due to adverse effect of drug, initial encounter
Use when anaphylaxis occurs due to a correctly administered drug.
Applicable To
- Drug-induced anaphylaxis
Excludes
- Anaphylactic shock due to serum (T80.52XA)
Clinical Validation Requirements
- Documented adverse reaction to a drug administered correctly
- Temporal relationship to drug administration
Coding Notes
Sequence T88.6XXA before specific drug adverse effect codes.
T80.52XA - Anaphylactic shock due to serum, initial encounter
Use when anaphylaxis is directly linked to serum administration.
Applicable To
- Serum-induced anaphylaxis
Excludes
- Anaphylactic shock due to drug (T88.6XXA)
Clinical Validation Requirements
- Reaction following serum administration
- Temporal relationship to serum infusion
Coding Notes
Document the specific serum and timing of reaction.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Anaphylactic Reaction to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code T78.2XXA.
Impact
Clinical: May lead to inappropriate treatment., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims due to insufficient documentation.
Mitigation Strategy
Always review patient history for potential triggers., Use structured templates to capture all necessary details.
Impact
Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate data for research and quality metrics.
Mitigation Strategy
Identify and document the specific trigger to use the appropriate code.
Impact
Frequent use of unspecified codes like T78.2XXA can trigger audits.
Mitigation Strategy
Ensure thorough documentation and identification of specific triggers.
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.
