About the R04 Code Range
Bleeding from the breathing passages includes nosebleeds, throat bleeding, and bleeding from other respiratory sites.
R04 separates nosebleeds, called epistaxis, under R04.0 from throat bleeding under R04.1 and hemoptysis under R04.2. Other respiratory sites fall under R04.8, which separates acute lung bleeding of unknown cause in infants from bleeding at other sites. R04.9 identifies bleeding from respiratory passages when the site is unspecified.
