| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| J84.178 | Other interstitial pulmonary diseases with fibrosis | Use when PPFE is confirmed by imaging and histology without progressive fibrotic phenotype. |
|
| J84.170 | Interstitial pulmonary disease with progressive fibrotic phenotype | Use when PPFE shows a progressive fibrotic phenotype. |

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 Lung Fibroelastosis
Primary ICD-10-CM Codes for lung fibroelastosis
Decision Criteria
clinical Criteria
- HRCT and biopsy findings consistent with PPFE
Applicable To
- Pleuroparenchymal fibroelastosis (PPFE)
Excludes
- Idiopathic interstitial pneumonia (J84.112)
Clinical Validation Requirements
- HRCT showing upper lobe pleural thickening and subpleural fibrosis
- Histopathology confirming intra-alveolar fibrosis with septal elastosis
Code-Specific Risks
- Misclassification as unspecified pulmonary fibrosis (J84.10)
Coding Notes
- Ensure documentation specifies PPFE features to avoid using unspecified codes.
J84.170 - Interstitial pulmonary disease with progressive fibrotic phenotype
Use when PPFE shows a progressive fibrotic phenotype.
Applicable To
- Progressive pleuroparenchymal fibroelastosis
Excludes
- Non-progressive PPFE (J84.178)
Clinical Validation Requirements
- Documented FVC decline >10% over 12 months
- HRCT showing increased fibrosis
Coding Notes
Ensure progression is documented to justify this code.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Solitary pulmonary nodule
R91.1Differential 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 Lung Fibroelastosis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code J84.178.
Impact
Clinical: Misdiagnosis risk., Regulatory: Non-compliance with coding standards., Financial: Potential for denied claims.
Mitigation Strategy
Ensure specific PPFE features are documented.
Impact
Reimbursement: Potential underpayment due to less specific coding., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Use J84.178 or J84.170 based on disease progression.
Impact
Risk of using non-specific codes for PPFE.
Mitigation Strategy
Ensure documentation supports the use of specific PPFE 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.
