Poisoning by caffeine, intentional self-harm, sequela

This code signifies the long-term effects or complications arising from a deliberate act of self-poisoning with caffeine. It indicates that the patient experienced an overdose of caffeine with the intent to harm themselves, and is now presenting with residual health issues directly attributable to that event. These sequelae can manifest in various organ systems depending on the severity and duration of the initial poisoning.

Apply this code when documenting conditions or symptoms that are a direct consequence of a past, intentional caffeine overdose. This includes chronic cardiac arrhythmias, persistent neurological deficits, or ongoing gastrointestinal issues that have been medically linked to the self-inflicted poisoning. It is used after the acute phase of the poisoning has passed, and the patient is being treated for the lasting effects.

• Always ensure documentation clearly links the current condition to a past intentional caffeine poisoning.
• This code requires an "S" (sequela) seventh character, indicating a late effect.
• Code additional diagnoses to specify the exact nature of the sequela (e.g., specific cardiac arrhythmia, chronic gastritis).
