Poisoning by salicylates, undetermined, subsequent encounter

This code signifies a poisoning event involving salicylates where the intent (accidental, intentional self-harm, assault, or undetermined) cannot be definitively established. The "subsequent encounter" designation indicates that the patient is receiving follow-up care for the sequelae or ongoing management of this poisoning, after the initial treatment.

This code is appropriate for encounters where a patient is being seen for ongoing monitoring, treatment of residual effects, or complications stemming from a salicylate poisoning, and the circumstances surrounding the poisoning remain unclear. This would apply after the initial acute phase of treatment has concluded.

• Ensure documentation clearly states the encounter is for follow-up care related to the poisoning.
• Confirm that the intent of the poisoning is explicitly documented as "undetermined" or that there is insufficient information to classify it otherwise.
• Do not use for initial acute care encounters; a different 7th character would be required.
