ICD-10-CM Code J90
Pleural effusion, not elsewhere classified

Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
| ICD-10 from 2011 - 2016

J90 is a billable ICD code used to specify a diagnosis of pleural effusion, not elsewhere classified. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code J90 is used to code Pleural effusion

Pleural effusion is excess fluid that accumulates in the pleural cavity, the fluid-filled space that surrounds the lungs. This excess can impair breathing by limiting the expansion of the lungs. Various kinds of pleural effusion, depending on the nature of the fluid and what caused its entry into the pleural space, are hydrothorax (serous fluid), hemothorax (blood), urinothorax (urine), chylothorax (chyle), or pyothorax (pus). Pneumothorax is the accumulation of air in the pleural space.
