Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the R04 range.

About the R04 Code Range
ICD-10 code R04 covers various types of bleeding from the respiratory passages, including the nose, throat, and lungs. It is used to identify and classify hemorrhages from specific respiratory sites like epistaxis (nosebleeds), throat bleeding, and coughing up blood (hemoptysis).
These codes help healthcare providers document conditions such as epistaxis (R04.0), commonly known as nosebleeds, including anterior and posterior bleeding or trauma-related nasal bleeding. Bleeding from the throat or pharynx is coded as R04.1, while coughing up blood, medically termed hemoptysis, is classified under R04.2. For bleeding from other parts of the respiratory system, the codes R04.8 and R04.89 apply, covering rare causes like pulmonary hemorrhage or tracheal bleeding. The code R04.81 is specifically used for acute idiopathic pulmonary hemorrhage in infants. When the exact source of respiratory bleeding is unclear, R04.9 is used. These details make the ICD-10 code for hemorrhage from respiratory passages essential for accurate diagnosis, treatment planning, and medical coding of respiratory bleeding disorders.
