Poisoning by chloramphenicol group, self-harm, subs

This code signifies a patient presenting for follow-up care or treatment of complications arising from an intentional overdose or self-poisoning with a chloramphenicol-based medication. The poisoning was a deliberate act of self-harm, and this encounter is not the initial presentation for the event.

Apply this code for subsequent hospital visits, outpatient clinic appointments, or rehabilitation sessions where the primary reason for the encounter is monitoring, managing sequelae, or providing ongoing care related to a past chloramphenicol self-poisoning attempt. This includes situations like managing bone marrow suppression or other organ damage that developed after the initial acute phase.

• Always sequence this code after any codes for the specific manifestations or complications of the poisoning.
• Ensure documentation clearly states "intentional self-harm" and that this is a "subsequent encounter" for the poisoning event.
• Do not use for initial acute care or for accidental poisonings.
