Adverse effect of oral contraceptives, sequela

This code signifies a long-term or residual condition resulting from a past adverse reaction to oral contraceptive medications. It indicates that the initial adverse effect has resolved, but its lasting consequences continue to impact the patient's health. Examples include chronic hypertension, persistent migraines, or permanent organ damage attributed to prior oral contraceptive use.

Apply this code when documenting a condition that is a direct, permanent consequence of an adverse effect from oral contraceptives, and the acute adverse event itself is no longer present. This is appropriate for follow-up encounters where the sequela is being managed, rather than the initial adverse reaction.

• Always sequence this code after the code for the specific sequela (e.g., chronic hypertension, migraine).
• Ensure documentation clearly links the current condition to a past adverse effect of oral contraceptives.
• Do not use for acute adverse reactions; refer to the appropriate T38.4X5A or T38.4X5D codes for initial or subsequent encounters.
