Poisoning by emetics, intentional self-harm, sequela

This code signifies the long-term effects or complications arising from a deliberate act of self-poisoning using an emetic substance. It indicates that the acute poisoning event has resolved, but the patient is now experiencing residual health issues directly attributable to that intentional self-harm.

Apply this code when documenting conditions such as chronic esophageal damage, persistent electrolyte imbalances, or other lasting organ dysfunction that developed as a consequence of a past intentional overdose of an emetic. This code is appropriate for follow-up encounters addressing these sequelae, not for the initial acute poisoning event.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., K22.1 for esophagitis).
• Ensure documentation clearly links the current condition to the past intentional emetic poisoning.
• The "S" in the seventh character indicates sequela, meaning the residual effect of a previous injury or illness.
