Retained uterin contracep dev in pregnancy, third trimester

This code signifies the presence of an intrauterine contraceptive device (IUD) that remains in situ during the third trimester of a pregnancy. This situation can pose risks to both the mother and the fetus, necessitating careful monitoring and management.

Assign this code when documentation clearly indicates a pregnant patient in her third trimester with a confirmed retained IUD. This diagnosis is typically made via ultrasound or physical examination.

• Always sequence this code as a secondary diagnosis, following the code for the primary obstetric condition.
• Ensure the documentation specifies "third trimester" to support the use of this specific subcategory.
• Do not confuse this with codes for IUD complications outside of pregnancy or IUD removal procedures.
