Poisn by oth antacids & anti-gstrc-sec drugs, slf-hrm, subs

This code signifies a patient presenting for follow-up care or treatment of complications arising from an intentional overdose of antacids or other medications that reduce gastric acid secretion. This includes substances like proton pump inhibitors (PPIs), H2 blockers, or other antacids, taken with the explicit intent of self-harm. The patient is no longer in the initial acute phase of poisoning.

Apply this code when documenting subsequent encounters for patients who previously attempted self-harm by ingesting an excessive amount of antacids or anti-gastric-secretion drugs. This could include appointments for ongoing psychiatric evaluation, management of lingering physical side effects, or follow-up for complications that developed after the initial poisoning event. It is used after the initial treatment of the acute poisoning.

• Ensure documentation clearly states "intentional self-harm" and that the encounter is not the initial treatment for the acute poisoning.
• Always code the specific drug or drug class if known and documented, in addition to this code.
• Consider additional codes for any resulting physical or psychological sequelae of the poisoning.
