Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the J70 range.
Radiation Pneumonitis
Inflammation of the lung due to harmful effects of ionizing or non-ionizing radiation.
Smoke Inhalation Injury
Pulmonary injury following the breathing in of toxic smoke from burning materials such as plastics, synthetics, building materials, etc. This injury is the most frequent cause of death in burn patients.
About the J70 Code Range
ICD-10 code section J70 covers respiratory conditions caused by various external agents such as radiation, drugs, and smoke inhalation. These codes help identify lung diseases directly linked to environmental or treatment-related exposures.
This section includes codes for acute and chronic lung issues caused by radiation, such as J70.0 (acute pulmonary radiation disease) and J70.1 (chronic pulmonary radiation fibrosis). It also addresses drug-induced interstitial lung disorders, with J70.2 for acute cases and J70.3 for chronic cases, alongside an unspecified category J70.4. Smoke inhalation injuries are captured under J70.5, often referred to as inhalation injury or smoke inhalation injury. Additional codes like J70.8 and J70.9 cover respiratory conditions from other or unspecified external agents, including rare occupational lung diseases like silo-fillers' disease and environmental lung disease. Using these ICD-10 codes ensures accurate classification of respiratory problems stemming specifically from external harmful exposures.
