Activity, cross country skiing

This code identifies cross-country skiing as the specific activity involved in an injury or health condition. It helps to pinpoint the mechanism of injury or the context of a health event, providing crucial detail beyond just the nature of the injury itself. This information is vital for understanding risk factors and for public health surveillance.

This code should be appended to an external cause code (e.g., W00-Y34) when a patient presents with an injury or adverse health effect that occurred while participating in cross-country skiing. It is used to provide specificity about the activity when the primary diagnosis relates to a condition sustained during this sport.

• Always use in conjunction with an external cause code and a primary diagnosis code for the injury or condition.
• Ensure the medical record explicitly documents "cross-country skiing" as the activity; do not assume based on general winter sports.
• Distinguish from downhill skiing (Y93.21) or snowboarding (Y93.22) based on documentation.
