Explosion and rupture of boiler (W35)
ICD-10 code W35 covers injuries related to the explosion and rupture of boilers. These codes specify whether the medical encounter is the first treatment, a follow-up, or care for lasting effects of such an accident.
The code W35 and its extensions address incidents involving the accidental explosion of boilers or pressure vessels, commonly referred to as accidents caused by boiler or pressure vessel explosions. The initial encounter code W35.XXXA applies when the patient is being treated for the first time after such an event. The subsequent encounter code W35.XXXD is used for follow-up visits, while the sequela code W35.XXXS relates to complications or conditions that develop later as a direct result of the explosion. Medical coders use these specific distinctions to accurately capture the timing and ongoing care related to injuries from boiler explosions, which assists in proper reporting and resource allocation.
