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

This code signifies a harmful reaction resulting from unintentional contact with a venomous fish species other than those specifically classified elsewhere. The "subsequent encounter" designation indicates that the patient is receiving follow-up care for the initial toxic effect, such as wound management, monitoring for systemic symptoms, or treatment of complications.

Apply this code when a patient presents for ongoing treatment of symptoms or complications arising from an accidental sting or bite from an unspecifed venomous fish. This includes scenarios like wound infection, persistent pain, or neurological sequelae after the initial acute phase of treatment.

• Always assign an external cause code (V00-Y99) to describe the circumstances of the injury.
• Ensure documentation clearly specifies "accidental" and "subsequent encounter" for accurate code selection.
• Distinguish from initial encounters (A) or sequela (S) codes, which represent different phases of care.
