Explosion and rupture of gas cylinder (W36) ICD-10-CM
The W36 code range covers explosion and rupture of gas cylinder with 21 ICD-10-CM diagnosis codes. 15 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
7th Character Note
Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.
- The appropriate 7th character is to be added to each code from category W36
7th Character
Indicates that a seventh character is to be assigned to codes in a subcategory.
- A - initial encounter
- D - subsequent encounter
- S - sequela

About the W36 Code Range
These codes describe explosions and ruptures of gas cylinders as external causes involving inanimate mechanical forces.
The subdivisions identify the container: an aerosol can, air tank, or pressurized-gas tank. Separate subdivisions cover other gas cylinders and unspecified gas cylinders. The seventh character distinguishes an initial encounter (A), subsequent encounter (D), or sequela (S).
