Primary blast injury of bronchus, unspecified, subs encntr

This code signifies a primary blast injury affecting an unspecified bronchus, indicating damage directly caused by the overpressure wave of an explosion. The injury could range from contusion to rupture, and the specific bronchus involved is not documented. This code is used for encounters following the initial treatment phase.

Use this code for follow-up visits, rehabilitation, or subsequent evaluations of a patient who previously sustained a primary blast injury to an unspecified bronchus. This applies when the patient is receiving continuing care for the effects of the initial injury, such as monitoring for complications or managing persistent symptoms.

• Ensure documentation clearly states "primary blast injury" and specifies a bronchus, even if unspecified.
• Verify the encounter is not the initial treatment for the injury; the "D" seventh character indicates a subsequent encounter.
• Do not use if the injury is secondary to a blast (e.g., impact from flying debris); this code is specific to the blast wave itself.
