Adverse effect of oral contraceptives, initial encounter

This code signifies an undesirable or harmful reaction experienced by a patient due to the therapeutic use of an oral contraceptive. It indicates that the patient is presenting for the first time for treatment of this adverse effect.

Apply this code when a patient develops symptoms or conditions directly attributable to their oral contraceptive medication, and this is their initial visit for evaluation or treatment of these symptoms. Examples include new-onset hypertension, migraines, or abnormal bleeding linked to the contraceptive.

• Always code the specific manifestation of the adverse effect first, followed by this code.
• Ensure documentation clearly states the oral contraceptive as the cause of the adverse effect, not an overdose or poisoning.
• Distinguish from "underdosing" (T38.4X6-) or "poisoning" (T38.4X1-).
