Poisoning by aminoglycosides, intentional self-harm, subs

This code signifies a deliberate act of self-poisoning using an aminoglycoside antibiotic, where the patient is receiving follow-up care for the sequelae of the initial event. It indicates that the patient intentionally ingested or administered an excessive amount of this specific class of medication with the intent to harm themselves, and the current encounter is for ongoing management or complications.

Use this code for subsequent encounters when a patient is being treated for the effects of an intentional aminoglycoside overdose, such as renal failure, ototoxicity, or other systemic complications, after the initial acute phase of treatment. This applies to follow-up appointments, hospital readmissions for complications, or ongoing monitoring related to the self-harm event.

• Ensure documentation clearly specifies intentional self-harm and the specific substance as an aminoglycoside.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Always code the specific adverse effect or poisoning manifestation first, followed by this code as an external cause.
