Poisoning by tetracyclines, accidental (unintentional), subs

This code signifies an adverse health event resulting from the unintended ingestion or exposure to tetracycline antibiotics, where the patient is presenting for follow-up care after the initial treatment of the poisoning. This could involve ongoing monitoring, management of residual effects, or treatment of complications arising from the initial accidental overdose.

Apply this code when a patient is seen for a subsequent visit related to an accidental tetracycline poisoning. This includes scenarios such as a patient returning to the clinic for blood work to check liver function after initial treatment, or for evaluation of persistent gastrointestinal symptoms stemming from the poisoning event. It is used after the acute phase of treatment has concluded.

• Always sequence this code after the primary diagnosis for the reason for the subsequent encounter, if applicable.
• Ensure documentation clearly indicates the poisoning was accidental and that this is not the initial encounter for the poisoning.
• Distinguish from intentional self-harm or assault, which would require different poisoning codes.
