Primary blast injury of lung, unspecified, initial encounter

This code signifies lung damage resulting from the direct impact of a blast wave, without specifying the exact nature or severity of the injury. It covers the initial presentation of such an injury, indicating the patient is receiving active treatment for the condition.

This code is appropriate for patients presenting with respiratory symptoms, such as dyspnea, chest pain, or hemoptysis, following exposure to an explosion where a primary blast injury to the lungs is suspected or confirmed. It is used when the specific type of lung damage (e.g., contusion, laceration) has not yet been determined or documented.

• Always assign a more specific code if the type of primary blast injury to the lung is known (e.g., contusion, laceration).
• Ensure documentation clearly links the lung injury to a blast event.
• The "A" at the end indicates an initial encounter for active treatment; use subsequent encounter codes for follow-up care.
