ICD Code J84.1

ICD code J84.1 is pulmonary fibrosis, a condition characterized by scarring and thickening of the lung tissue, which leads to breathing difficulties and reduced oxygen supply in the body.

1. Presence of chronic, progressive shortness of breath (dyspnea) not explained by other causes

2. Persistent dry cough

3. Fine inspiratory crackles on lung auscultation

4. Evidence of diffuse interstitial lung abnormalities on high-resolution computed tomography (HRCT), such as reticular opacities, honeycombing, or ground-glass changes

5. Restrictive pattern on pulmonary function tests (reduced total lung capacity and forced vital capacity)

6. Decreased diffusing capacity for carbon monoxide (DLCO)

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

8. Histopathological confirmation of interstitial fibrosis if clinically indicated

Relevant CPT codes that may be used to treat ICD code J84.1 include:

- 94010 (Spirometry, including graphic record, total and timed vital capacity, expiratory flow rate measurement(s), with or without maximal voluntary ventilation)

- 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, rigid or flexible, including fluoroscopic guidance, when performed; with bronchial alveolar lavage)

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

- 88108 (Cytopathology, concentration technique, smears and interpretation)

- 71045 (Radiologic examination, chest; single view)

- 71250 (Computed tomography, thorax; without contrast material)

These CPT codes are commonly associated with the management and treatment of conditions identified by ICD code J84.1.
