Toxic eff of cntct w oth venom marine animals, undet, sqla

This code signifies the long-term or late effects resulting from an exposure to an unspecified venomous marine animal, where the initial toxic effect was of an undetermined nature. It indicates that the acute phase of the poisoning has passed, and the patient is now experiencing residual symptoms or complications.

Apply this code when documenting a patient presenting with chronic or persistent health issues directly attributable to a past, unconfirmed toxic exposure from a marine animal. This is appropriate when the specific marine animal responsible for the venomous contact was never identified, and the initial toxic effect was not clearly classified as accidental, intentional self-harm, assault, or undetermined.

• Requires a seventh character "S" to indicate sequela, meaning the residual effect of a past injury or illness.
• Only use when the specific venomous marine animal cannot be identified from the medical record.
• Ensure documentation clearly links the current condition to a previous, undetermined toxic marine animal exposure.
