Expsr to chng in air pressr in arcrft during descent, sqla

This code signifies a long-term or residual health condition resulting from a rapid decrease in cabin pressure during an aircraft's descent. Such an event can lead to barotrauma affecting various body systems, particularly the ears, sinuses, and lungs, with sequelae manifesting after the initial incident.

Apply this code when documenting a chronic or persistent medical problem directly attributable to a sudden change in air pressure experienced during an aircraft's descent. This includes conditions like chronic otitis media, persistent sinus pain, or pulmonary issues that developed as a consequence of the barotrauma.

• Always use in conjunction with a code identifying the specific sequela (e.g., H65.11- for chronic serous otitis media).
• Ensure documentation clearly links the current condition to the past aircraft pressure change.
• The "S" in the seventh character indicates sequela, meaning it's used for conditions arising as a late effect of the initial exposure.
