    ICD-10-CM Code For Hydatidiform Mole: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group O01 includes diagnoses for hydatidiform mole, covering complete and partial molar pregnancies and abnormal products of conception arising from trophoblastic proliferation. These ICD-10-CM diagnosis codes are used to document pregnancy losses due to molar gestation, capture the type of mole and any associated complications relevant to care. Accurate coding within the ICD-10-CM O01 group supports proper claim adjudication and complete clinical documentation for pregnancy with abortive outcome.

    The ICD-10-CM O01 group represents hydatidiform mole diagnoses, abnormal gestational trophoblastic proliferations originating in the placenta. These conditions affect the reproductive system during pregnancy and range from complete to partial mole variants. Accurate coding matters for correct classification of pregnancy with abortive outcome and supports appropriate billing and clinical recordkeeping.

    Typical Clinical Scenarios

    • A 24-year-old woman presents to the emergency department with heavy, painless vaginal bleeding and passage of grape-like tissue at 10 weeks' gestation after a period of amenorrhea. Ultrasound demonstrates a heterogeneous intrauterine mass with no identifiable fetal pole and markedly elevated beta-hCG levels, prompting uterine evacuation for suspected complete hydatidiform mole; a diagnosis from this group is assigned based on clinical, laboratory, and imaging findings. Typical codes: O01.0
    • A 32-year-old woman seen in outpatient gynecology for persistent abnormal uterine bleeding and enlarged uterine size at 12 weeks' gestation during routine prenatal evaluation; ultrasound shows retained molar tissue consistent with an invasive process but with no acute hemorrhage, leading to planned surgical management and close follow-up. Typical codes: O01.1
    • A 19-year-old patient presents to her primary care provider after a spontaneous first-trimester pregnancy loss with incomplete clinical information and nondiagnostic imaging, where the clinician documents a hydatidiform mole pending pathologic confirmation and schedules histopathology and follow-up monitoring of hCG levels. Typical codes: O01.9
