Poisoning by propionic acid derivatives, self-harm, subs

This code signifies a patient presenting for follow-up care related to an intentional overdose of propionic acid derivatives, such as ibuprofen or naproxen. The poisoning was a deliberate act of self-harm, and the current encounter is for ongoing management or evaluation after initial treatment.

Apply this code when a patient is seen for a subsequent visit (e.g., medication management, psychiatric evaluation, or monitoring for long-term effects) following an intentional self-poisoning with propionic acid derivatives. This includes situations where the patient is stable but requires continued care related to the initial event.

• Ensure documentation clearly states "intentional self-harm" and that the substance involved was a propionic acid derivative.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Always sequence this code after any acute poisoning codes (e.g., T39.312A) if the patient is still being treated for acute effects.
