What is the ICD-10 code for idiopathic pulmonary fibrosis?

The ICD-10 code for idiopathic pulmonary fibrosis is J84.112, which requires confirmation of a UIP pattern on HRCT.

How do you code pulmonary fibrosis with a known cause?

Code J84.17 is used for pulmonary fibrosis with a known cause, such as systemic sclerosis, and requires coding the underlying disease first.

Code	Description	When to Use	Key Documentation
J84.10	Unspecified interstitial pulmonary disease	Use when the specific cause of fibrosis is not identified.	Clinical diagnosis of pulmonary fibrosis without specific etiology Radiological evidence of fibrosis
J84.112	Idiopathic pulmonary fibrosis	Use when HRCT confirms UIP pattern and no other cause is identified.	HRCT showing UIP pattern Exclusion of known causes
J84.17	Interstitial pulmonary disease with fibrosis in diseases classified elsewhere	Use when fibrosis is associated with a known systemic disease.	Documentation of underlying systemic disease Radiological evidence of fibrosis

Documentation & Coding Risks

Avoid these common issues when documenting Fibrosis of Lung.

Failure to document HRCT findings

Impact

Clinical: May lead to misdiagnosis., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims.

Mitigation

Ensure HRCT reports are reviewed and included in documentation., Train staff on documentation standards.

Using J84.10 when a specific cause is documented

Impact

Reimbursement: May lead to incorrect reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases accuracy of clinical data.

Mitigation

Identify and code the specific cause of fibrosis if known.

Use of unspecified codes

Impact

High risk of audit if unspecified codes are used when more specific codes are applicable.

Mitigation

Ensure thorough documentation and use of specific codes when possible.
