Hydatidiform mole O01- >

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation. In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere." Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code. "In diseases classified elsewhere" codes are never permitted to be used as first listed or principle diagnosis codes. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition.

A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as O01. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Information
  • A gestational disorder characterized by an abnormal placenta with marked enlargement of the chorionic villi and hyperplasia of the villous trophoblastic cells. According to the amount of villous involvement, a hydatidiform mole is defined as complete or partial. Most molar pregnancies are complete and are characterized by generalized hydropic villous changes. Partial moles are characterized by a mixture of large hydropic villi and normal placenta tissue. Complete moles are usually diploid and typically present between the eleventh and twenty-fifth week of pregnancy, whereas partial moles are usually triploid and usually present around the nineteenth week of pregnancy. The incidence of choriocarcinoma is higher in patients with complete hydatidiform mole. When a hydatidiform mole invades the myometrium and broad ligament, or it is found in distant sites as vagina, vulva, and lung, it is referred as invasive mole.
  • A slow-growing tumor that develops from trophoblastic cells (cells that help an embryo attach to the uterus and help form the placenta) after fertilization of an egg by a sperm. A hydatidiform mole contains many cysts (sacs of fluid). It is usually benign (not cancer) but it may spread to nearby tissues (invasive mole). It may also become a malignant tumor called choriocarcinoma. Hydatidiform mole is the most common type of gestational trophoblastic tumor.
  • Trophoblastic hyperplasia associated with normal gestation, or molar pregnancy. It is characterized by the swelling of the chorionic villi and elevated human chorionic gonadotropin. Hydatidiform moles or molar pregnancy may be categorized as complete or partial based on their gross morphology, histopathology, and karyotype.
  • Trophoblastic hyperplasia associated with normal gestation, or molar pregnancy; characterized by the swelling of the chorionic villi and elevated human chorionic gonadotropin; hydatidiform moles or molar pregnancy may be categorized as complete or partial based on their gross morphology, histopathology, and karyotype.
