Adverse effect of oxytocic drugs, subsequent encounter

This code signifies a patient experiencing a negative or harmful reaction to a medication used to induce labor or contract the uterus, such as oxytocin, during a follow-up visit. The adverse effect is not due to poisoning or overdose, but rather an expected or unexpected side effect of the drug's therapeutic use.

Apply this code when a patient presents for ongoing management or evaluation of an adverse effect from an oxytocic drug, and this is not their initial encounter for the problem. This includes situations where the patient is being monitored for complications like uterine hyperstimulation, fetal distress, or postpartum hemorrhage that developed after oxytocic administration.

• Requires a seventh character "D" for subsequent encounter, indicating ongoing care for the adverse effect.
• Always sequence the code for the specific adverse effect (e.g., uterine hyperstimulation, fetal distress) first, followed by this code.
• Distinguish from poisoning (T36-T50 with 5th or 6th character 1-4) or underdosing (T36-T50 with 5th or 6th character 6).
