Adverse effect of other psychostimulants, subs encntr

This code signifies a harmful or unintended reaction to a psychostimulant medication, other than those specifically classified elsewhere, that occurs during a follow-up visit or ongoing treatment. It indicates that the patient is experiencing an undesirable side effect from a prescribed psychostimulant, not an overdose or poisoning.

Apply this code when a patient presents for management of an adverse effect from a psychostimulant, such as methylphenidate or amphetamine, during a subsequent encounter. This includes follow-up appointments where the ongoing impact of the adverse effect is being monitored or treated.

• Always sequence this code after the code for the specific adverse effect being treated.
• Ensure the documentation clearly states the adverse effect is due to a psychostimulant and that this is not the initial encounter for the adverse event.
• Distinguish from poisoning (T43.6X1-T43.6X4) or underdosing (T43.6X6-).
