Specific Coding for Explosion and rupture of gas cylinderOverview

Non-specific codes like W36 require more characters. Use one of these billable codes instead:

  • W36.1 for Explosion and rupture of aerosol can

  • W36.2 for Explosion and rupture of air tank

  • W36.3 for Explosion and rupture of pressurized-gas tank

  • W36.8 for Explosion and rupture of other gas cylinder

  • W36.9 for Explosion and rupture of unspecified gas cylinder

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to W36: its own notes plus those printed at block W20-W49 and Chapter 20. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

From Block W20-W49 Exposure to inanimate mechanical forces applies to 510 codes
  • assault (X92-Y09)
  • contact or collision with animals or persons (W50-W64)
  • exposure to inanimate mechanical forces involving military or war operations (Y36.-, Y37.-)
  • intentional self-harm (X71-X83)

Notes

General instructions on how these codes are used.

From Chapter 20 (V00-Y99) External causes of morbidity and mortality applies to 7,461 codes
  • This chapter permits the classification of environmental events and circumstances as the cause of injury, and other adverse effects. Where a code from this section is applicable, it is intended that it shall be used secondary to a code from another chapter of the Classification indicating the nature of the condition. Most often, the condition will be classifiable to Chapter 19, Injury, poisoning and certain other consequences of external causes (S00-T88). Other conditions that may be stated to be due to external causes are classified in Chapters I to XVIII. For these conditions, codes from Chapter 20 should be used to provide additional information as to the cause of the condition.

7th Character

Every code in the category takes a 7th character from the listed values, with the placeholder X filling any empty positions before it.

  • The appropriate 7th character is to be added to each code from category W36
Values for category W36 Encounter: Initial, Subsequent, Sequela
  • Ainitial encounter
  • Dsubsequent encounter
  • Ssequela

Questions About W36Overview

What is the ICD-10 code for explosion and rupture of gas cylinder?

W36 is the ICD-10-CM category for explosion and rupture of gas cylinder, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is W36 (Explosion and rupture of gas cylinder) a billable code?

No. This is a category header that groups the codes for explosion and rupture of gas cylinder, and headers cannot be submitted on claims. Claims for explosion and rupture of gas cylinder need a more specific code from this category, such as W36.1XXA, W36.1XXD, and W36.1XXS.

Can W36 be reported with a code from Y36?

Not as a rule. The Excludes1 note at block W20-W49, which applies to W36, lists "exposure to inanimate mechanical forces involving military or war operations (Y36.-, Y37.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
