Hydatidiform mole; an abnormal pregnancy characterized by an abnormal placenta with swollen chorionic villi.
Medical necessity is established by the presence of abnormal pregnancy symptoms and confirmatory diagnostic testing results (ultrasound and hCG levels).Treatment is necessary to prevent complications, such as hemorrhage, infection, and malignant transformation.
Obstetrician-gynecologist;management includes diagnosis via ultrasound and hCG levels, treatment (often surgical evacuation), and follow-up monitoring for malignant transformation.
In simple words: A hydatidiform mole is an abnormal pregnancy where the placenta develops abnormally, forming grape-like cysts.This isn't a normal pregnancy and might need medical attention.It's usually not cancerous, but it can sometimes spread or become cancerous.
Hydatidiform mole is a gestational trophoblastic disease characterized by the abnormal development of the placenta.The chorionic villi, which normally develop into the placenta, become swollen and cystic, forming grape-like clusters.This can range from a complete mole (absence of fetal tissue) to a partial mole (presence of some fetal tissue).It is usually benign but may become invasive or malignant.Further classification may include specifying if the mole is complete (O01.0) or incomplete/partial (O01.1).Additional codes from category O08 may be used to identify associated complications.
Example 1: A 30-year-old woman presents with vaginal bleeding and an enlarged uterus at 10 weeks gestation.Ultrasound reveals a hydatidiform mole.The patient undergoes dilation and curettage (D&C) to remove the molar tissue. Post-procedure hCG monitoring is implemented., A 25-year-old woman with a history of irregular menses presents with persistent nausea and vomiting at 8 weeks gestation.Elevated hCG levels and ultrasound findings are consistent with a complete hydatidiform mole. She requires suction curettage followed by close monitoring of hCG levels to ensure complete removal of the mole., A 35-year-old woman experiences vaginal bleeding at 12 weeks gestation. Imaging reveals a partial hydatidiform mole. A combination of close monitoring, expectant management and potential surgical intervention are discussed, tailored to the patient's clinical picture and preferences.
Detailed history and physical examination, including symptoms (vaginal bleeding, abdominal pain, excessive nausea/vomiting), ultrasound imaging findings, serum beta-hCG levels, pathology report from the removed tissue (confirming the diagnosis and the type of mole).
** The specific type of hydatidiform mole (complete or partial) should be documented and coded when possible.Regular follow-up care and monitoring of hCG levels are crucial following treatment.
