About W36.9

W36.9 is the ICD-10-CM diagnosis code for explosion and rupture of unspecified gas cylinder. It belongs to category W36 (explosion and rupture of gas cylinder), block W20-W49 (exposure to inanimate mechanical forces) and chapter 20 (external causes of morbidity). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within W36, choose W36.9 (unspecified gas cylinder) only when documentation doesn't support a more specific option: aerosol can (W36.1), air tank (W36.2), pressurized-gas tank (W36.3) and other gas cylinder (W36.8).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
