Adverse effect of caffeine, sequela

This code signifies a long-term or residual effect resulting from a previous adverse reaction to caffeine. It indicates that a patient experienced an undesirable or harmful response to caffeine, and now, at a later date, is presenting with a persistent condition or symptom directly attributable to that past event.

Use this code when documenting a patient's current condition that is a direct consequence of a prior adverse effect from caffeine, such as chronic anxiety, sleep disturbance, or cardiac arrhythmia that developed after a significant caffeine overdose and has not resolved. It is appropriate for follow-up encounters where the sequela of the initial adverse event is being managed.

• Ensure documentation clearly links the current condition to a past adverse caffeine event.
• Do not use for acute caffeine toxicity; this code is specifically for sequelae.
• Requires an additional code to specify the nature of the sequela (e.g., specific anxiety disorder, sleep disorder).
