Code Classification

  • Neoplasms
    (C00–D49)
    • Malignant neoplasms of female genital organs
      (C51-C58)
      • Malignant neoplasm of corpus uteri
        (C54)

C54.9 is a billable diagnosis code used to specify a medical diagnosis of malignant neoplasm of corpus uteri, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

This code 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 reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic corpus uteri or Neoplasm, neoplastic uterus, uteri, uterine body or Neoplasm, neoplastic uterus, uteri, uterine cornu or Neoplasm, neoplastic uterus, uteri, uterine corpus .

Unspecified diagnosis codes like C54.9 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.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Adenosarcoma of corpus uteri
  • Adenosarcoma of uterus
  • Carcinofibroma of corpus uteri
  • Carcinoma of corpus uteri
  • Carcinosarcoma of corpus uteri
  • Carcinosarcoma of uterus
  • Complex mixed and stromal malignant neoplasm of corpus uteri
  • Leiomyosarcoma of corpus uteri
  • Leiomyosarcoma of uterus
  • Malignant germ cell neoplasm of corpus uteri
  • Malignant neoplasm of body of uterus
  • Malignant neoplasm of cornu of corpus uteri
  • Malignant neoplasm of corpus uteri, excluding isthmus
  • Peripheral neuroectodermal neoplasm of corpus uteri
  • Peripheral neuroectodermal tumor
  • Primary malignant neoplasm of body of uterus
  • Primary papillary carcinoma of body of uterus
  • Primary poorly differentiated endocrine carcinoma of corpus uteri
  • Primitive neuroectodermal tumor of corpus uteri
  • Rhabdomyosarcoma of corpus uteri
  • Sarcoma of corpus uteri
  • Serous carcinoma of body of uterus
  • Squamous cell carcinoma of corpus uteri
  • Transitional cell carcinoma of corpus uteri
  • Undifferentiated carcinoma of corpus uteri

Clinical Classification

Index to Diseases and Injuries References

The following annotation back-references for this diagnosis code are found in the injuries and diseases index. The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM code(s).

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10-CM Code Edits are applicable to this code:

  • 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 .

Convert C54.9 to ICD-9-CM

  • ICD-9-CM Code: 182.0 - Malig neo corpus uteri
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

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


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.
