Contact with other hot tap-water, initial encounter

This code signifies an injury resulting from direct exposure to hot tap water from sources other than a bathtub or shower. This typically involves burns or scalds sustained when an individual comes into contact with excessively heated water from a sink, hose, or other spigot.

Use this code when documenting an initial encounter for a burn or scald caused by hot tap water from a source like a kitchen sink, utility sink, or outdoor spigot. This code is appropriate for injuries sustained during activities such as washing hands, doing dishes, or filling containers.

• Ensure the documentation clearly specifies "tap water" and excludes immersion in a bathtub or shower.
• Verify this is the initial encounter for the injury; subsequent care would use a different seventh character.
• Always code the nature of the injury (e.g., T20-T25 for burns) first, followed by this external cause code.
