| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| J45.990 | Exercise-induced bronchospasm | Use when symptoms are explicitly linked to exercise and confirmed by objective testing. |
|
| J45.909 | Unspecified asthma | Use when asthma symptoms are present but not specifically linked to exercise. |

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Exercise-Induced Asthma to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code J45.990.
Impact
Clinical: May lead to inappropriate treatment plans., Regulatory: Increases risk of audit and compliance issues., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Ensure thorough documentation of exercise as a trigger, Use templates to guide documentation
Impact
Reimbursement: May result in lower reimbursement rates., Compliance: Increases risk of audit due to lack of specificity., Data Quality: Leads to inaccurate clinical data representation.
Mitigation Strategy
Query provider to confirm exercise as a trigger and use J45.990.
Impact
Using unspecified codes when specific codes apply increases audit risk.
Mitigation Strategy
Ensure documentation clearly specifies exercise as a trigger and includes objective test results.
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.
