| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| J84.112 | Idiopathic pulmonary fibrosis | Use when HRCT shows UIP pattern and other causes are excluded. |
|
| J70.4 | Drug-induced interstitial lung disorders | Use when ILD is temporally related to drug exposure. |

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

Decision Criteria
clinical Criteria
- HRCT shows UIP pattern
documentation Criteria
- Exclusion of other known causes
Applicable To
- Usual interstitial pneumonia (UIP)

- Pulmonary fibrosis due to known causes (J70.4)
Clinical Validation Requirements
- UIP pattern on HRCT
- Exclusion of known causes such as CTD or environmental exposures
Code-Specific Risks
- Misclassification if exclusion criteria are not documented
Coding Notes
- Ensure documentation of exclusion criteria for idiopathic classification.
J70.4 - Drug-induced interstitial lung disorders
Use when ILD is temporally related to drug exposure.
Applicable To
- Interstitial lung disease due to medications
Excludes
- Idiopathic pulmonary fibrosis (J84.112)
Clinical Validation Requirements
- Temporal relationship with drug exposure
- Improvement upon drug cessation
Coding Notes
Ensure documentation of drug exposure and response to cessation.
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 Interstitial Lung Disease to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code J84.112.
Impact
Clinical: May lead to misdiagnosis or inappropriate treatment., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims.
Mitigation Strategy
Use specific terminology, Include detailed clinical findings
Impact
Reimbursement: May lead to lower reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases accuracy of clinical data.
Mitigation Strategy
Use specific codes like J84.112 or J70.4 when the type of ILD is identified.
Impact
Risk of audits due to use of unspecified codes when specific codes are applicable.
Mitigation Strategy
Ensure thorough documentation and use of specific codes.
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.
