Adverse effect of chloramphenicol group, subs encntr

This code signifies a harmful or unintended reaction experienced by a patient due to the use of a medication belonging to the chloramphenicol drug class. The "subsequent encounter" indicates that the patient is receiving follow-up care for this adverse effect, rather than the initial diagnosis or treatment.

Apply this code when a patient presents for ongoing management, monitoring, or treatment of an adverse effect caused by chloramphenicol or a related drug. This includes situations where the patient is being seen for complications, worsening symptoms, or evaluation of the long-term impact of the drug reaction after the initial presentation.

• Always sequence this code after the code for the specific manifestation of the adverse effect.
• Ensure documentation clearly states the adverse effect is due to a chloramphenicol group drug and that this is a follow-up visit.
• Do not use for poisoning, underdosing, or initial treatment of the adverse effect.
