Version 2020 Billable Code Diagnoses For Females Only Neoplasm Malignant Primary

Valid for Submission

C57.4 is a billable code used to specify a medical diagnosis of malignant neoplasm of uterine adnexa, unspecified. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code C57.4 might also be used to specify conditions or terms like carcinosarcoma of uterine adnexa or malignant neoplasm of uterine adnexa or primary malignant neoplasm of uterine adnexa or primary mucinous carcinoma of uterine adnexa or primary serous carcinoma of uterine adnexa.

The code C57.4 is applicable to female patients only. It is clinically and virtually impossible to use this code on a non-female patient.

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: adnexa (uterine) or uterus, uteri, uterine adnexa NEC .

The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2020 through 09/30/2020.

Table of Neoplasms

The code C57.4 is included 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.

Information for Patients

Uterine Cancer

The uterus, or womb, is the place where a baby grows when a women is pregnant. There are different types of uterine cancer. The most common type starts in the endometrium, the lining of the uterus. This type is also called endometrial cancer.

The symptoms of uterine cancer include

Abnormal vaginal bleeding or discharge
Trouble urinating
Pelvic pain
Pain during intercourse

Uterine cancer usually happens after menopause. It is more common in women who have obesity. You also have a higher risk if you took estrogen-only hormone replacement therapy (menopausal hormone therapy) for many years.

Tests to find uterine cancer include a pelvic exam, imaging tests, and a biopsy. The most common treatment is a hysterectomy, which is surgery to remove the uterus. Sometimes the surgery also removes the ovaries and fallopian tubes. Other treatments include hormone therapy, radiation therapy, and chemotherapy. Some women get more than one type of treatment.
