Other diseases of the pleura (J90-J94)

Codes J90 through J94 cover a variety of specific diseases affecting the pleura, the thin lining around the lungs. These codes are used to classify different types of pleural effusions, pneumothorax (air leaks), plaques, and other distinctive pleural conditions.

This range includes J90, describing pleural effusion not classified elsewhere, known by terms like exudative pleural effusion or hydrothorax. J91 codes pleural effusions related to other diseases, including malignant pleural effusion under J91.0. Pleural plaques, which may be asbestos-related (J92.0) or not (J92.9), are fibrotic thickenings of the pleura. The J93 series covers pneumothorax types, including spontaneous tension pneumothorax (J93.0) and chronic pneumothorax (J93.81). Other pleural conditions like chylous effusion (J94.0), fibrothorax from scarring (J94.1), and hemothorax (J94.2) are also included. These codes help medical professionals accurately record complex pleural diseases such as pleurisy, pneumococcal pleurisy, asbestos-induced fibrosis, and various air or fluid leaks around the lungs.
