Patient presents with postpartum hemorrhage and retained placenta.  Following delivery of the infant, the placenta failed to spontaneously expel within 30 minutes.  Manual extraction of the placenta was attempted, however, complete removal was unsuccessful.  Ultrasound examination confirms retained placental fragments or products of conception within the uterine cavity.  The patient exhibits signs and symptoms consistent with retained placenta, including continued vaginal bleeding, lower abdominal pain, and uterine tenderness.  Differential diagnoses considered include uterine atony and placental accreta.  Risk factors for retained placenta such as prior Cesarean section, preterm delivery, and advanced maternal age were assessed.  Treatment plan includes administration of uterotonic medications such as oxytocin and prostaglandins to promote uterine contractions and expulsion of the retained tissue.  Surgical intervention, specifically dilation and curettage (DandC) or hysteroscopy, may be required if medical management fails.  Patient is monitored for complications such as postpartum infection, hemorrhage, and Sheehan syndrome.  ICD-10 code O72.1, retained placenta without hemorrhage, or O72.0, retained placenta with hemorrhage, will be applied depending on the patient's presentation.  CPT codes for procedures performed, such as manual removal of placenta (59160), Dilation and Curettage (58120), or hysteroscopy (58558), will be documented accordingly.  Patient education provided regarding potential complications and follow-up care.  Close monitoring and ongoing assessment of postpartum bleeding and uterine involution are essential.
