Contact w steam and hot vapors, undetermined intent, subs

This code signifies an injury resulting from exposure to steam or hot vapors where the circumstances surrounding the incident are unclear or cannot be determined. It specifically applies to follow-up care for such an injury, indicating that the initial treatment has already occurred.

Use this code for subsequent encounters when a patient presents for ongoing management of burns or other injuries sustained from steam or hot vapors, and the provider's documentation indicates that the intent (e.g., accidental, intentional self-harm, assault) of the exposure remains unknown. This is appropriate for follow-up visits for wound care, physical therapy, or medication adjustments related to the initial undetermined steam/hot vapor injury.

• Ensure documentation clearly states "undetermined intent" for the steam/hot vapor exposure.
• Only use the "D" seventh character for subsequent encounters, after the initial treatment of the injury.
• Always code the specific nature of the injury (e.g., burn, respiratory tract injury) first, followed by this external cause code.
