List of ICD-9 codes 460–519: diseases of the respiratory system

List of ICD-9 codes 460–519: Diseases of the Respiratory System encompasses a range of conditions, disorders, and diseases affecting the respiratory system. The International Classification of Diseases, Ninth Revision (ICD-9), categorizes these conditions under codes 460 to 519. This classification aids in the systematic recording, analysis, and interpretation of mortality and morbidity data globally. The respiratory system diseases are divided into several categories, including acute respiratory infections, chronic obstructive pulmonary disease and allied conditions, pneumonia and influenza, and other diseases of the respiratory system.

Acute Respiratory Infections (460–466)

Acute respiratory infections are among the most common health problems worldwide. They range from the common cold (460) to acute bronchitis and bronchiolitis (466). These conditions are characterized by the sudden onset of symptoms such as coughing, sneezing, and, in more severe cases, breathing difficulties.

Chronic Obstructive Pulmonary Disease and Allied Conditions (490–496)

Chronic Obstructive Pulmonary Disease (COPD) (496) is a chronic inflammatory lung disease that causes obstructed airflow from the lungs. It is typically caused by long-term exposure to irritating gases or particulate matter, most often from cigarette smoke. Allied conditions include bronchiectasis (494) and chronic bronchitis (491).

Pneumonia and Influenza (480–488)

Pneumonia (480 to 486) is an infection that inflames the air sacs in one or both lungs, which may fill with fluid or pus. Influenza (487), commonly known as the flu, is a viral infection that attacks the respiratory system. The ICD-9 codes for pneumonia and influenza are crucial for tracking outbreaks and managing public health resources.

Other Diseases of the Respiratory System (490–519)

This category includes a wide range of other respiratory conditions, such as pulmonary emphysema (492), asthma (493), and respiratory conditions due to external agents (500–508). It also covers diseases of the pleura (510–519), such as pleurisy and pneumothorax.

The above overview provides a structured insight into the ICD-9 codes 460–519, focusing on diseases of the respiratory system. Each condition is unique in its presentation, management, and implications for public health. The classification system aids healthcare professionals and researchers in diagnosing, treating, and studying respiratory diseases systematically.
