Underdosing of unspecified psychotropic drug, subs encntr

This code signifies a patient's underdosing of a psychotropic medication where the specific drug is not identified, and the patient is receiving ongoing care for the sequelae of this underdosing. It indicates that the patient did not take enough of their prescribed psychotropic drug, leading to a recurrence or worsening of their underlying mental health condition.

Apply this code when a patient presents for follow-up care related to the adverse effects or worsening of their condition due to insufficient intake of an unspecifed psychotropic medication. This is appropriate for subsequent visits after the initial encounter where the underdosing was first identified.

• Ensure documentation clearly states "underdosing" and "subsequent encounter."
• Only use this code when the specific psychotropic drug is not documented. If known, a more specific T43.xxXD code should be used.
• Always code the underlying mental health condition as the primary diagnosis, with this code as a secondary diagnosis.
