Other contact with other fish, sequela

This code describes the long-term or late effects resulting from an encounter with an unspecified type of fish, excluding venomous or shark encounters. These sequelae could manifest as chronic pain, scarring, infection, or functional impairment directly attributable to the original incident.

Apply this code when documenting conditions that are residual effects of a past injury or adverse event involving contact with a non-specific fish. This is appropriate when the acute phase of the injury has passed, and the patient presents for treatment of the lasting consequences. Examples include chronic wound care for a fish bite or scar revision following a fish-related injury.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, scar).
• Ensure documentation clearly links the current condition to a past "other fish" contact.
• The "S" in the 7th character indicates sequela; do not use for initial or subsequent encounters.
