Contact with hot tap water, undetermined intent, subs encntr

This code signifies an injury resulting from exposure to hot tap water where the circumstances surrounding the contact are unclear or unknown. It specifically applies to follow-up care for such an injury, indicating that the initial assessment and treatment have already occurred. The "undetermined intent" aspect means it's not definitively accidental, self-harm, or assault.

Apply this code for subsequent encounters when a patient presents for ongoing treatment or evaluation of burns or other injuries sustained from hot tap water, and the provider's documentation does not specify whether the contact was accidental, intentional self-harm, or due to an assault. This is appropriate for conditions like wound care, physical therapy, or follow-up appointments after the initial injury.

• Ensure documentation clearly indicates "undetermined intent" regarding the hot tap water contact.
• The "D" seventh character is crucial for subsequent encounters; do not use for initial care.
• Always code the specific burn or injury first, then this external cause code as a secondary diagnosis.
