2021 ICD-10-CM Code C57.00
Malignant neoplasm of unspecified fallopian tube
Valid for Submission
C57.00 is a billable diagnosis code used to specify a medical diagnosis of malignant neoplasm of unspecified fallopian tube. The code C57.00 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code C57.00 might also be used to specify conditions or terms like any t/any n and m1 , carcinoma of fallopian tube, malignant tumor involving an organ by direct extension from fallopian tube, malignant tumor involving an organ by separate metastasis from fallopian tube, malignant tumor involving bladder by direct extension from fallopian tube , malignant tumor involving bladder by separate metastasis from fallopian tube, etc.
The code C57.00 is applicable to female patients only. It is clinically and virtually impossible to use this code on a non-female patient.
Unspecified diagnosis codes like C57.00 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code C57.00 is grouped in the following groups for version MS-DRG V38.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. 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 09/30/2021.

Convert C57.00 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code C57.00 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.

Information for Patients
Uterine Cancer
Also called: Endometrial 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.
