Maternal care due to uterine scar from oth previous surgery

This code signifies ongoing obstetric care for a pregnant patient whose uterus has a scar resulting from a prior surgical procedure other than a Cesarean section. This uterine scar presents a potential risk factor during the current pregnancy, requiring specific monitoring and management.

Apply this code when a pregnant patient has a documented uterine scar from a myomectomy, metroplasty, or other non-C-section uterine surgery, and this condition is influencing the current pregnancy management. Documentation should clearly state the presence of the scar and its impact on maternal care.

• Do not use this code for uterine scars specifically from a previous Cesarean section (use O34.21-).
• Ensure the medical record specifies the type of previous uterine surgery if known, as this code is for "other" surgeries.
• This code is typically a secondary diagnosis, accompanying a code for the current pregnancy status (e.g., Z3A.xx).
