Activity, underwater diving and snorkeling

This code identifies an injury or adverse health effect that occurred while an individual was engaged in underwater diving activities, including both scuba diving and snorkeling. It signifies that the patient's condition is directly attributable to their participation in these aquatic sports.

Use this code as an external cause code when documenting injuries such as barotrauma, decompression sickness, marine life stings, or near-drowning incidents that occurred during a diving or snorkeling excursion. It helps to specify the activity context for the primary injury diagnosis.

• Always use this code as a secondary diagnosis following the primary injury or condition code.
• Ensure documentation clearly links the injury to the underwater diving or snorkeling activity.
• Consider additional external cause codes for specific environmental factors (e.g., marine animal contact) if applicable.
