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

This code signifies a harmful reaction resulting from direct contact with a venomous fish species other than those specifically classified (e.g., stingray, scorpionfish), where the exposure was intentionally inflicted by another person. The "subsequent encounter" indicates that the patient is receiving follow-up care for the initial injury, such as wound checks, ongoing symptom management, or treatment of complications.

This code is appropriate for documenting subsequent visits for a patient who was intentionally exposed to the venom of an unspecified venomous fish by another individual. Examples include follow-up appointments for wound care, management of persistent pain or swelling, or treatment of secondary infections arising from such an assault.

• Ensure documentation clearly states the encounter is for follow-up care of an injury from a venomous fish assault.
• Verify that the specific type of venomous fish is not otherwise classified in T63.5.
• Confirm the intent of the exposure was an assault, not accidental or undetermined.
