Underdosing of oral contraceptives, sequela

This code indicates a patient's underdosing of oral contraceptive medications, resulting in a long-term complication or condition arising from that underdosing. It signifies that the insufficient dosage has led to a subsequent health issue, rather than an acute event.

Use this code when documenting a condition or symptom that is a direct consequence of a patient consistently taking less than the prescribed amount of oral contraceptives over time. This typically applies to situations like an unintended pregnancy or other hormonal imbalances directly attributed to chronic underdosing.

• Always assign a secondary code for the specific sequela (e.g., Z3A.00 for unintended pregnancy).
• Ensure documentation clearly links the current condition to the historical underdosing of oral contraceptives.
• This code is for the sequela of underdosing, not for the act of underdosing itself.
