J84: ICD10 Code for Other interstitial pulmonary diseases

J84 refers to Other interstitial pulmonary diseases, a group of severe or chronic lung conditions that impact gas exchange and often require urgent or long-term respiratory care. These diseases can lead to widespread inflammation, fluid accumulation, or fibrosis of the lung tissue.

Symptoms

• Severe shortness of breath – Common in ARDS (J80) and pulmonary edema (J81)
• Low oxygen levels – Detected via pulse oximetry or blood gas tests
• Rapid breathing and respiratory distress – Often seen in J80 and J82
• Crackles or rales on auscultation – Associated with fluid or fibrosis (J81, J84)
• Chronic cough or fatigue – Typical in interstitial lung disease (J84)
• Allergic symptoms and eosinophilia – Seen in J82 cases

Diagnosis

Diagnosis of Other interstitial pulmonary diseases includes clinical examination, chest X-ray or high-resolution CT scan, arterial blood gases, pulmonary function tests, and in some cases, lung biopsy. Identifying the underlying cause is critical for targeted treatment and prognosis.

ICD10 Code Usage

ICD10 code J84 is used by intensivists, pulmonologists, internists, and hospitalists. It facilitates critical care documentation, respiratory therapy management, and coding for ARDS, non-cardiogenic edema, and fibrotic lung diseases.

Related Codes

• J80 – Acute respiratory distress syndrome
• J81 – Pulmonary edema
• J82 – Pulmonary eosinophilia, not elsewhere classified

FAQs

Q1: What is ICD10 code J84?
A: It refers to Other interstitial pulmonary diseases, a respiratory condition marked by lung inflammation, fluid accumulation, or fibrosis that impairs oxygen exchange.

Q2: How does ARDS (J80) differ from pulmonary edema (J81)?
A: ARDS is usually caused by inflammation or sepsis, while pulmonary edema often results from heart failure or fluid overload.

Q3: What causes eosinophilic lung disease (J82)?
A: It can be idiopathic, drug-induced, or allergic in nature, and is identified by increased eosinophils in the lungs.

Q4: Are interstitial lung diseases (J84) curable?
A: Most are not curable but can be managed with anti-inflammatory or antifibrotic therapies, oxygen, and pulmonary rehab.

Q5: Who treats these conditions?
A: Pulmonologists, critical care specialists, and respiratory therapists collaborate to manage these complex lung disorders.

Conclusion

ICD10 code J84 enables clinicians to document and treat Other interstitial pulmonary diseases accurately, supporting intensive care, pulmonary rehabilitation, and long-term disease tracking for patients with complex respiratory pathologies.
