Toxic effect of unspecified seafood, assault, subs encntr

This code signifies a patient presenting for follow-up care related to a toxic reaction caused by consuming an unknown type of seafood, where the exposure was intentionally inflicted by another person. The patient is no longer in the acute phase of treatment but is receiving ongoing management or monitoring for the effects of the poisoning.

This code is appropriate for subsequent encounters when a patient is being treated for lingering symptoms or complications arising from a seafood poisoning that was determined to be an assault. Examples include follow-up appointments for persistent gastrointestinal issues, neurological deficits, or other long-term effects after the initial acute care.

• Ensure documentation clearly states the encounter is subsequent and the poisoning was due to an assault.
• Verify that the type of seafood ingested was not identified in the medical record.
• Pair with external cause codes (X-codes) to fully describe the circumstances of the assault, if available.
