Other diseases of the respiratory system (J96-J99)

ICD-10 codes J96 to J99 are used to classify a variety of respiratory system diseases that do not fit into common categories like infections or asthma. This range primarily covers different forms of respiratory failure, other lung and bronchial disorders, mediastinal conditions, and respiratory problems linked to other diseases.

The codes from J96 specify states of respiratory failure, including acute, chronic, and acute-on-chronic respiratory failure, with distinctions based on presence of hypoxia (low oxygen) or hypercapnia (high carbon dioxide). For example, conditions like hypoxemic respiratory failure or hypercapnic respiratory failure correspond to codes such as J96.01 and J96.02. J98 covers other respiratory disorders affecting the bronchus, lungs, diaphragm, and mediastinum, including acute bronchospasm (J98.01), atelectasis or pulmonary collapse (J98.11), and various lung conditions like restrictive lung disease and pulmonary fibrosis variant syndromes (J98.4). This range also flags complications such as mediastinitis (J98.51) and diaphragm disorders like paralysis or displacement (J98.6). Lastly, J99 identifies respiratory disorders that occur in the course of other systemic diseases, for instance, lung involvement in connective tissue diseases or pulmonary histoplasmosis. These codes help medical coders accurately capture complex respiratory diagnoses for clinical documentation and billing, ensuring nuanced respiratory conditions are properly recorded and recognized.
