Poisoning by caffeine, undetermined, sequela

This code signifies a long-term or residual effect resulting from an unconfirmed or unknown intent of caffeine poisoning. It indicates that the initial acute event of caffeine toxicity has resolved, but the patient continues to experience related health issues. The "undetermined" nature means it's unclear whether the poisoning was accidental, intentional self-harm, or assault.

Apply this code when documenting a patient presenting with persistent symptoms or conditions directly attributable to a past caffeine overdose, where the circumstances surrounding the original poisoning event were not definitively established. This is appropriate for follow-up encounters addressing chronic complications or sequelae.

• Ensure documentation clearly links the current condition to a previous caffeine poisoning and specifies the "undetermined" intent.
• This code is for the sequela (S) of the poisoning; do not use for acute caffeine toxicity.
• Always sequence this code after the code for the specific residual condition being treated.
