C58 - Malignant neoplasm of placenta
ICD-10: | C58 |
Short Description: | Malignant neoplasm of placenta |
Long Description: | Malignant neoplasm of placenta |
Status: | Valid for Submission |
Version: | ICD-10-CM 2023 |
Code Classification: |
C58 is a billable ICD-10 code used to specify a medical diagnosis of malignant neoplasm of placenta. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
The code C58 is applicable to female patients aged 12 through 55 years inclusive. It is clinically and virtually impossible to use this code on a non-female patient outside the stated age range.
The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic fetal membrane or Neoplasm, neoplastic placenta .

Clinical Information
- Choriocarcinoma-. a malignant metastatic form of trophoblastic tumors. unlike the hydatidiform mole, choriocarcinoma contains no chorionic villi but rather sheets of undifferentiated cytotrophoblasts and syncytiotrophoblasts (trophoblasts). it is characterized by the large amounts of chorionic gonadotropin produced. tissue origins can be determined by dna analyses: placental (fetal) origin or non-placental origin (choriocarcinoma, non-gestational).
- Choriocarcinoma, Non-gestational-. a highly malignant choriocarcinoma derived from the non-placental origin such as the totipotent cells in the testis, the ovary, and the pineal gland. it produces high levels of chorionic gonadotropin and can metastasize widely through the bloodstream to the lungs, brain, liver, bone, and other viscera by the time of diagnosis.
- Gestational Trophoblastic Disease-. a group of diseases arising from pregnancy that are commonly associated with hyperplasia of trophoblasts (trophoblast) and markedly elevated human chorionic gonadotropin. they include hydatidiform mole, invasive mole (hydatidiform mole, invasive), placental-site trophoblastic tumor (trophoblastic tumor, placental site), and choriocarcinoma. these neoplasms have varying propensities for invasion and spread.
- Fallopian Tube Gestational Choriocarcinoma|Gestational Choriocarcinoma of Fallopian Tube|Gestational Choriocarcinoma of the Fallopian Tube-. a malignant trophoblastic tumor that arises from the fallopian tube during pregnancy.
- Gestational Choriocarcinoma-. a rare, highly malignant epithelial tumor that develops from a hydatidiform mole (50%), following abortion (25%), or during normal pregnancy (22%). it is characterized by the presence of invasive and anaplastic trophoblastic tissue composed of intermediate trophoblastic cells, cytotrophoblasts and syncytiotrophoblasts, abundant vascularity, and secretion of human chorionic gonadotropin. because of rapid growth and a high propensity for hemorrhage, this neoplasm often constitutes a medical emergency.
- Ovarian Gestational Choriocarcinoma|Gestational Ovarian Choriocarcinoma-. a rare malignant trophoblastic tumor that arises from the ovary as a result of ectopic ovarian pregnancy. there is no germ cell component present.
- Uterine Corpus Choriocarcinoma|Gestational Uterine Corpus Choriocarcinoma|Uterine Corpus Gestational Choriocarcinoma-. an aggressive malignant tumor arising from trophoblastic cells in the uterus during pregnancy. approximately half of the cases develop from a complete hydatidiform mole. there is often marked elevation of human chorionic gonadotropin (hcg) in the blood. choriocarcinomas disseminate rapidly through the hematogenous route; the lungs are most frequently affected.
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to this diagnosis code:
Includes
IncludesThis note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- choriocarcinoma NOS
- chorionepithelioma NOS
Type 1 Excludes
Type 1 ExcludesA type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
Index to Diseases and Injuries References
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for this diagnosis code are found in the injuries and diseases index:
- - Carcinoma (malignant) - See Also: Neoplasm, by site, malignant;

Code Edits
The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10 Code Edits are applicable to this code:
- Maternity diagnoses - The Medicare Code Editor detects inconsistencies in maternity cases by checking a patient's age and any diagnosis on the patient's record. The maternity code edits apply to patients age ange is 9–64 years inclusive (e.g., diabetes in pregnancy, antepartum pulmonary complication).
- Diagnoses for females only - The Medicare Code Editor detects inconsistencies between a patient’s sex and any diagnosis on the patient’s record, these edits apply to FEMALES only .

Table of Neoplasms
This code is referenced in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.
Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Patient Education
Tumors and Pregnancy
Tumors during pregnancy are rare, but they can happen. Tumors can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. The most common cancers in pregnancy are breast cancer, cervical cancer, lymphoma, and melanoma. Cancer itself rarely harms the baby, and some cancer treatments are safe during pregnancy. You and your health care provider will work together to find the best treatment. Your options will depend on how far along the pregnancy is, as well as the type, size, and stage of your cancer.
Another type of tumor that women can get is called a gestational trophoblastic disease (GTD). It happens when a fertilized egg doesn't become a fetus. GTD is not always easy to find. It is usually benign, but some types can be malignant. The most common type of GTD is a molar pregnancy. In its early stages, it may look like a normal pregnancy. You should see your health care provider if you have vaginal bleeding (not menstrual bleeding).
Treatment depends on the type of tumor, whether it has spread to other places, and your overall health.
