Poisoning by caffeine, accidental (unintentional), sequela

This code signifies a long-term or residual effect resulting from an accidental overdose or toxic exposure to caffeine. It indicates that the acute poisoning event has passed, but the patient is still experiencing health problems directly attributable to that past caffeine intoxication.

Apply this code when documenting conditions such as persistent cardiac arrhythmias, chronic anxiety disorders, or neurological deficits that are directly linked as a sequela to a previously occurring, unintentional caffeine poisoning. This code is appropriate for follow-up encounters addressing these lasting effects, not the initial acute poisoning.

• Always sequence this sequela code first, followed by codes for the specific residual condition(s) being treated.
• Ensure documentation clearly links the current condition to a past accidental caffeine poisoning event.
• Do not use this code for acute caffeine poisoning; refer to the appropriate acute poisoning codes for initial encounters.
