Toxic effect of contact w oth venomous fish, assault, init

This diagnosis code signifies a harmful physiological reaction resulting from direct contact with a venomous fish species other than those specifically classified elsewhere (e.g., stingrays, jellyfish). The injury is explicitly due to an intentional act of violence or aggression by another party.

Apply this code when documenting a patient presenting with symptoms such as localized pain, swelling, erythema, or systemic effects following an assault involving a venomous fish. This is for the initial treatment of the acute injury.

• Ensure documentation clearly states the injury was due to an "assault" and not accidental or undetermined intent.
• Confirm the venomous fish is not a stingray (T63.6X-) or other specified marine animal.
• The "A" suffix indicates an initial encounter for active treatment of the injury.
