Poisoning by enzymes, intentional self-harm, subs encntr

This code signifies a patient presenting for follow-up care or treatment of complications arising from a deliberate overdose or self-poisoning using an enzyme-based substance. This could involve substances like certain industrial enzymes, biological agents, or even high doses of therapeutic enzymes taken with suicidal intent. The patient is no longer in the acute phase of the poisoning but is receiving ongoing management.

Apply this code when documenting subsequent encounters for patients who intentionally harmed themselves by ingesting or administering enzymes. This includes visits for monitoring organ damage, managing psychological sequelae, or treating long-term effects after the initial acute poisoning event has been addressed. Examples include follow-up appointments after discharge from an emergency department or inpatient stay for enzyme poisoning.

• Ensure documentation clearly states "intentional self-harm" and that the encounter is not for the initial acute poisoning.
• Verify the substance involved is an enzyme; differentiate from other drug or chemical poisonings.
• Always sequence this code after any codes for specific conditions or injuries resulting from the poisoning.
