Hydatidiform mole
Chapter 15:Pregnancy, childbirth and the puerperium
ICD-10 O01 is a billable code used to indicate a diagnosis of hydatidiform mole.
Hydatidiform mole, also known as molar pregnancy, is a gestational trophoblastic disease characterized by abnormal growth of trophoblastic tissue, which can lead to the formation of a non-viable pregnancy. There are two types of hydatidiform moles: complete and partial. A complete mole occurs when an egg with no genetic material is fertilized, leading to the proliferation of placental tissue without fetal development. A partial mole involves the fertilization of a normal egg by two sperm, resulting in abnormal placental and fetal tissue. Patients may present with symptoms such as vaginal bleeding, excessive nausea and vomiting, and an enlarged uterus. Monitoring of human chorionic gonadotropin (HCG) levels is crucial, as elevated levels can indicate the presence of choriocarcinoma, a malignant form of gestational trophoblastic disease. Early diagnosis and management are essential to prevent complications and ensure appropriate follow-up care.
Detailed documentation of symptoms, HCG levels, and treatment plans is essential for accurate coding.
Patients presenting with vaginal bleeding and elevated HCG levels, requiring ultrasound for diagnosis.
Coders must be aware of the potential for choriocarcinoma and ensure that all relevant clinical details are captured.
Comprehensive documentation of maternal and fetal health, including any complications arising from the mole.
Management of high-risk pregnancies involving molar pregnancies and monitoring for malignancy.
High-risk factors must be documented, including previous molar pregnancies and family history of gestational trophoblastic disease.
Used for surgical management of hydatidiform mole.
Document indication for procedure and any complications.
Obstetricians should ensure that the procedure is justified based on clinical findings.
A complete hydatidiform mole occurs when an egg with no genetic material is fertilized, leading to abnormal placental tissue without fetal development. A partial mole involves fertilization of a normal egg by two sperm, resulting in both abnormal placental and some fetal tissue.
