How is T71.2 listed in the External Cause Index?

The External Cause of Injuries Index lists these routes under T71, the nearest indexed parent of T71.2. This is a separate index from the Alphabetic Index and is where external cause codes are looked up.

  • Suffocation (accidental) (by external means) (by pressure) (mechanical)

Inclusion terms

Alternative wording in documentation that is classified to T71.2.

  • Suffocation due to systemic oxygen deficiency due to low oxygen content in ambient air

Excludes1 — never code together — inherited from T71

The conditions below can never be reported together with T71.2 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • acute respiratory distress (syndrome) (J80)
  • anoxia due to high altitude (T70.2)
  • asphyxia NOS (R09.01)
  • asphyxia from carbon monoxide (T58.-)
  • asphyxia from inhalation of food or foreign body (T17.-)
  • asphyxia from other gases, fumes and vapors (T59.-)
  • respiratory distress (syndrome) in newborn (P22.-)

Use additional code — inherited from Chapter 19

Report an additional code alongside T71.2 to fully describe the condition. T71.2 is sequenced first.

  • code to identify any retained foreign body, if applicable (Z18.-)

Excludes2 — not included here — inherited from Chapter 19

The conditions below are not part of T71.2, but a patient may have both at the same time. When documentation supports it, T71.2 and the excluded code may both be reported.

  • birth trauma (P10-P15)
  • obstetric trauma (O70-O71)

Code also — inherited from T66-T78

Two codes may be needed to describe the condition fully. Whether T71.2 is sequenced first depends on the reason for the encounter.

  • , if applicable, place of occurrence, such as:
  • highway rest stop (Y92.523)
  • school (private) (public) (state) as the place of occurrence of the external cause (Y92.21-)
  • service areas as the place of occurrence of the external cause (Y92.52-)
  • single-family non-institutional (private) house as the place of occurrence of the external cause (Y92.01-)
  • transport vehicle as the place of occurrence of the external cause (Y92.81-)
