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

This code signifies a patient presenting with adverse effects resulting from the deliberate overdose or misuse of antacids or medications that reduce stomach acid production. The intent of the patient was to cause self-harm, and this encounter represents the initial assessment and treatment for this specific poisoning event.

Apply this code when documentation clearly indicates a patient intentionally ingested an excessive amount of antacids (e.g., calcium carbonate, aluminum hydroxide) or anti-gastric-secretion drugs (e.g., proton pump inhibitors, H2 blockers) with suicidal intent. This is appropriate for the emergency department visit or initial inpatient admission related to the poisoning.

• Always confirm the intent of self-harm is explicitly documented.
• Ensure the specific substance involved falls under "other antacids and anti-gastric-secretion drugs."
• Verify this is the patient's first encounter for this particular poisoning episode.
