ICD Code J84.112

ICD code J84.112 is idiopathic pulmonary fibrosis, a chronic lung disease characterized by progressive scarring of lung tissue with no known cause.

1. Progressive exertional dyspnea lasting more than three months

2. Persistent dry cough

3. Bibasilar inspiratory crackles on lung auscultation

4. Restrictive pattern on pulmonary function tests (reduced FVC, normal or increased FEV1/FVC ratio)

5. Decreased diffusing capacity for carbon monoxide (DLCO)

6. High-resolution CT scan showing usual interstitial pneumonia (UIP) pattern (subpleural, basal-predominant reticulation, honeycombing, and absence of features suggesting alternative diagnoses)

7. Exclusion of known causes of interstitial lung disease (such as connective tissue disease, drug toxicity, or environmental exposures)

8. Absence of significant lymphadenopathy, pleural disease, or airway disease on imaging

Relevant CPT codes that may be used to treat ICD code J84.112 include:

- 94010 (Spirometry, including graphic record)

- 94726 (Plethysmography for determination of lung volumes and, when performed, airway resistance)

- 94640 (Pressurized or nonpressurized inhalation treatment for acute airway obstruction or for sputum induction for diagnostic purposes)

- 31622 (Bronchoscopy, diagnostic)

- 32408 (Core needle biopsy, lung or mediastinum, percutaneous)

- 32607 (Thoracoscopy, surgical; with diagnostic biopsy of lung)

- 99457 (Remote physiologic monitoring treatment management services)

- 99454 (Device(s) supply with daily recording or programmed alert transmission, each 30 days)

- 96372 (Therapeutic, prophylactic, or diagnostic injection; subcutaneous or intramuscular)

- 96401 (Chemotherapy administration, subcutaneous or intramuscular; non-hormonal anti-neoplastic)

CPT code selection should be based on the specific services rendered and clinical scenario.
