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

The ICD-10 code for idiopathic pulmonary fibrosis is J84.112, used when HRCT confirms a UIP pattern and other causes are excluded.

How do you code progressive fibrotic phenotype in interstitial lung disease?

Use J84.170 for progressive fibrotic phenotype when there is documented fibrosis progression and an underlying condition.

Documentation & Coding Risks

Avoid these common issues when documenting Interstitial Pulmonary Fibrosis.

Vague documentation of fibrosis

Impact

Clinical: Misdiagnosis or inappropriate treatment, Regulatory: Non-compliance with coding standards, Financial: Potential reimbursement issues

Mitigation

Use specific terminology like 'idiopathic' and 'UIP pattern'., Document exclusion of other causes.

Using J84.9 when HRCT confirms UIP

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

Query for confirmation of idiopathic versus secondary causes and use J84.112 if confirmed.

Documentation of UIP pattern

Impact

Lack of specific HRCT findings can lead to audit issues.

Mitigation

Ensure detailed HRCT findings and multidisciplinary consensus are documented.
