Code Classification

  • Injury, poisoning and certain other consequences of external causes
    (S00–T88)
    • Other and unspecified effects of external causes
      (T66-T78)
      • Asphyxiation
        (T71)

T71.2 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of asphyxiation due to systemic oxygen deficiency due to low oxygen content in ambient air. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Asphyxiation due to systemic oxy defic due to low oxy in air

Coding Guidelines

The appropriate 7th character is to be added to each code from block Asphyxiation (T71). Use the following options for the aplicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela
