ICD-10-CM Code W94.3

Exposure to rapid changes in air pressure during descent

Version 2020 Non-Billable Code

Not Valid for Submission

W94.3 is a "header" nonspecific and non-billable 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 valid for the year 2020 for the submission of HIPAA-covered transactions.

ICD-10:W94.3
Short Description:Exposure to rapid changes in air pressure during descent
Long Description:Exposure to rapid changes in air pressure during descent

Consider the following ICD-10 codes with a higher level of specificity:

  • W94.31 - Exposure to sudden change in air pressure in aircraft during descent
  • W94.31XA - Exposure to sudden change in air pressure in aircraft during descent, initial encounter
  • W94.31XD - Exposure to sudden change in air pressure in aircraft during descent, subsequent encounter
  • W94.31XS - Exposure to sudden change in air pressure in aircraft during descent, sequela
  • W94.32 - Exposure to high air pressure from rapid descent in water
  • W94.32XA - Exposure to high air pressure from rapid descent in water, initial encounter
  • W94.32XD - Exposure to high air pressure from rapid descent in water, subsequent encounter
  • W94.32XS - Exposure to high air pressure from rapid descent in water, sequela
  • W94.39 - Exposure to other rapid changes in air pressure during descent
  • W94.39XA - Exposure to other rapid changes in air pressure during descent, initial encounter
  • W94.39XD - Exposure to other rapid changes in air pressure during descent, subsequent encounter
  • W94.39XS - Exposure to other rapid changes in air pressure during descent, sequela

Code Classification

  • External causes of morbidity and mortality (V01–Y98)
    • Exposure to electric current, radiation and extreme ambient air temperature and pressure (W85-W99)
      • Expsr to high and low air pressr and changes in air pressure (W94)
