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.

Clinical Information

A primary or metastatic malignant neoplasm involving the ovary. Most primary malignant ovarian neoplasms are either carcinomas (serous, mucinous, or endometrioid adenocarcinomas) or malignant germ cell tumors. Metastatic malignant neoplasms to the ovary include carcinomas, lymphomas, and melanomas.
A primary or metastatic malignant tumor involving the ovary. Most primary malignant ovarian neoplasms are either carcinomas (serous, mucinous, or endometrioid adenocarcinomas) or malignant germ cell tumors. Metastatic malignant neoplasms to the ovary include carcinomas, lymphomas, and melanomas.
Cancer that forms in tissues of the ovary (one of a pair of female reproductive glands in which the ova, or eggs, are formed). Most ovarian cancers are either ovarian epithelial carcinomas (cancer that begins in the cells on the surface of the ovary) or malignant germ cell tumors (cancer that begins in egg cells).
The ovaries are part of the female reproductive system. They produce a woman's eggs and female hormones. Each ovary is about the size and shape of an almond.cancer of the ovary is not common, but it causes more deaths than other female reproductive cancers. The sooner ovarian cancer is found and treated, the better your chance for recovery. But ovarian cancer is hard to detect early. Women with ovarian cancer may have no symptoms or just mild symptoms until the disease is in an advanced stage. Then it is hard to treat. Symptoms may include
- a heavy feeling in the pelvis
- pain in the lower abdomen
- bleeding from the vagina
- weight gain or loss
- abnormal periods
- unexplained back pain that gets worse
- gas, nausea, vomiting, or loss of appetite
to diagnose ovarian cancer, doctors do one or more tests. They include a physical exam, a pelvic exam, lab tests, ultrasound, or a biopsy. Treatment is usually surgery followed by chemotherapy. nih: national cancer institute
