Code Classification

  • External causes of morbidity and mortality
    (V01–Y99)
    • Exposure to electric current, radiation and extreme ambient air temperature and pressure
      (W85-W99)
      • Exposure to high and low air pressure and changes in air pressure
        (W94)

W94.3 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of exposure to rapid changes in air pressure during descent. 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 Exposure to rapid changes in air pressure during descent

Non-specific codes like W94.3 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for exposure to rapid changes in air pressure during descent:

  • W94.31 for Exposure to sudden change in air pressure in aircraft during descent - NON-BILLABLE CODE

  • Use W94.31XA for initial encounter - BILLABLE CODE

  • Use W94.31XD for subsequent encounter - BILLABLE CODE

  • Use W94.31XS for sequela - BILLABLE CODE

  • W94.32 for Exposure to high air pressure from rapid descent in water - NON-BILLABLE CODE

  • Use W94.32XA for initial encounter - BILLABLE CODE

  • Use W94.32XD for subsequent encounter - BILLABLE CODE

  • Use W94.32XS for sequela - BILLABLE CODE

  • W94.39 for Exposure to other rapid changes in air pressure during descent - NON-BILLABLE CODE

  • Use W94.39XA for initial encounter - BILLABLE CODE

  • Use W94.39XD for subsequent encounter - BILLABLE CODE

  • Use W94.39XS for sequela - BILLABLE CODE
