J90: ICD10 Code for Pleural effusion, not elsewhere classified
J90 is the ICD10 code used for documenting Pleural effusion, not elsewhere classified in clinical and billing records.

J90 refers to Pleural effusion, not elsewhere classified, a category of pleural diseases involving fluid buildup, scarring, or trapped air within the pleural space. These conditions can significantly impact lung function, cause chest pain, and require both diagnostic and interventional procedures.
Symptoms
- Chest pain – Often pleuritic in nature, sharp and worsened by breathing
- Shortness of breath – Common in pleural effusion (J90, J91) and pneumothorax (J93)
- Cough – Typically nonproductive in pleural diseases
- Decreased breath sounds – Suggestive of fluid or air in the pleural space
- Asymptomatic – Some pleural plaques (J92) are found incidentally
Diagnosis
Diagnosis of Pleural effusion, not elsewhere classified involves chest X-ray, CT scan, and ultrasound. Thoracentesis may be used to analyze pleural fluid. In pneumothorax, clinical exam and imaging quickly confirm trapped air. Pleural plaques are often seen on CT in asbestos-exposed individuals.
ICD10 Code Usage
ICD10 code J90 is used by pulmonologists, radiologists, thoracic surgeons, and hospitalists. It guides documentation for diagnostic evaluation, drainage procedures, pleurodesis, and monitoring of pleural complications from systemic diseases or trauma.
Related Codes
- J91 – Pleural effusion in conditions classified elsewhere
- J92 – Pleural plaque
- J93 – Pneumothorax and air leak
- J94 – Other pleural conditions
FAQs
Q1: What is ICD10 code J90?
A: It refers to Pleural effusion, not elsewhere classified, which involves abnormalities of the pleura, the lining surrounding the lungs, such as fluid accumulation, plaques, or air leaks.
Q2: What’s the difference between J90 and J91?
A: J90 is used when pleural effusion occurs independently; J91 is for effusions linked to other conditions like heart failure or cancer.
Q3: What are pleural plaques (J92)?
A: Localized thickening or calcification of the pleura, typically related to asbestos exposure, and often asymptomatic.
Q4: Is pneumothorax (J93) life-threatening?
A: It can be—especially if it progresses to tension pneumothorax, requiring emergency decompression.
Q5: Who treats these pleural conditions?
A: Pulmonologists, emergency physicians, thoracic surgeons, and interventional radiologists manage these cases.
Conclusion
ICD10 code J90 provides essential classification for diagnosing and treating Pleural effusion, not elsewhere classified, ensuring appropriate interventions such as thoracentesis, chest tube placement, and pleural disease management in various care settings.
