Compare key differences between these codes to ensure accurate selection
| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| J84.112 | Idiopathic pulmonary fibrosis | Use when HRCT confirms UIP pattern and other causes are excluded. |
|
| J84.170 | Interstitial lung disease with progressive fibrotic phenotype | Use when progressive fibrosis is documented and linked to an underlying condition. |

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

Essential facts and insights about Interstitial Pulmonary Fibrosis
Primary ICD-10-CM Codes for interstitial pulmonary fibrosis
Decision Criteria
clinical Criteria
- HRCT shows UIP pattern
documentation Criteria
- Exclusion of other known causes
Applicable To
- Usual interstitial pneumonia
Excludes
- Pulmonary fibrosis due to known causes
Clinical Validation Requirements
- HRCT showing basal/subpleural honeycombing and traction bronchiectasis
- Multidisciplinary diagnosis excluding known causes
Code-Specific Risks
- Misclassification if documentation is vague
- Incorrect use if UIP pattern is not confirmed
Coding Notes
- Ensure HRCT findings and multidisciplinary consensus are documented.
J84.170 - Interstitial lung disease with progressive fibrotic phenotype
Use when progressive fibrosis is documented and linked to an underlying condition.
Applicable To
- Progressive fibrosis in diseases classified elsewhere
Excludes
- Idiopathic pulmonary fibrosis without progression
Clinical Validation Requirements
- ≥10% FVC decline or increased fibrosis on HRCT
- Documentation of underlying condition
Coding Notes
Ensure documentation of progression and underlying condition.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Interstitial Pulmonary Fibrosis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code J84.112.
Impact
Clinical: Misdiagnosis or inappropriate treatment, Regulatory: Non-compliance with coding standards, Financial: Potential reimbursement issues
Mitigation Strategy
Use specific terminology like 'idiopathic' and 'UIP pattern'., Document exclusion of other causes.
Impact
Reimbursement: Potential underpayment due to less specific code, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate data for clinical research and quality measures
Mitigation Strategy
Query for confirmation of idiopathic versus secondary causes and use J84.112 if confirmed.
Impact
Lack of specific HRCT findings can lead to audit issues.
Mitigation Strategy
Ensure detailed HRCT findings and multidisciplinary consensus are documented.
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.
