Expsr to high air pressr from rapid descent in water, sqla

This code describes the long-term or residual effects resulting from a rapid decrease in altitude while submerged in water, commonly experienced by divers. These sequelae are typically related to barotrauma affecting various body systems due to the sudden pressure changes.

Apply this code when documenting conditions such as chronic ear pain, persistent sinus issues, neurological deficits, or joint pain that are directly attributed to a past incident of rapid descent during diving. This code is appropriate for follow-up visits addressing these lasting complications, not the initial acute injury.

• Always use this code with an additional code identifying the specific sequela (e.g., chronic otitis media, neurological disorder).
• Ensure documentation clearly links the current condition to a past rapid descent in water.
• The "S" in the seventh character indicates sequela, meaning it's used for complications or conditions that arise as a direct result of the initial injury.
