Expsr to high air pressure from rapid descent in water, subs

This code signifies an injury or adverse health effect resulting from a rapid decrease in atmospheric pressure experienced during a dive, specifically in a subsequent encounter. This can lead to conditions such as barotrauma of the ears or sinuses, decompression sickness, or other pressure-related injuries. The "subsequent encounter" indicates that the patient is receiving follow-up care for an injury that occurred previously.

Use this code for patients presenting for ongoing treatment, evaluation, or management of an injury sustained due to rapid descent in water. This includes follow-up appointments for conditions like middle ear barotrauma, inner ear decompression sickness, or pulmonary barotrauma that occurred during a prior diving incident. It is appropriate when the initial injury has already been diagnosed and treatment is continuing.

• Always assign an additional code to specify the nature of the injury (e.g., T70.0XXA for ear barotrauma).
• Ensure documentation clearly indicates that the patient is being seen for follow-up care related to a previously diagnosed diving injury.
• Distinguish from initial encounters (W94.32XA) and sequela encounters (W94.32XS) based on the patient's current stage of care.
