What ovarian cancer ICD codes can I use?

If you’re looking for ovarian cancer ICD codes, five are specifically available for it:

  1. C56.9 - Malignant neoplasm of unspecified ovary

This ICD-10 code is meant to be used on a patient confirmed to have a malignant neoplasm in an ovary. Malignant neoplasm is another term used when healthcare professionals refer to cancerous tumors. In the case of this ICD-10 code, the malignant neoplasm is in the ovary, but given its unspecified label, it’s not identified as to which ovary it’s located.

  1. C56.1 - Malignant neoplasm of right ovary

This is the same as Item 1, but it’s confirmed that the malignant neoplasm is in the right ovary.

  1. C56.2 - Malignant neoplasm of left ovary

This is the same as Item 1, but it’s confirmed that the malignant neoplasm is in the left ovary.

  1. Z85.43 - Personal history of malignant neoplasm of ovary

This ICD-10 code is meant to be used on a patient confirmed to have a personal history of malignant neoplasm in their ovary. This means the patient has had ovarian cancer before. Do note that this is not acceptable as a principal diagnosis because this type of ICD-10 code is meant to explain something about a person’s health condition. For example, this can explain why a patient is dealing with certain problems in the ovary that ovarian cancer left in its wake.

  1. Z80.41 - Family history of malignant neoplasm of ovary

This is the same as Item 4, but this time, the patient has a family history of ovarian cancer. This can be used to explain how at risk a patient is of getting it or that it’s likely they got it because “it runs in the family.”

Do note that there are ICD-10 codes for malignant neoplasms in the fallopian tubes as well.

Are these ovarian cancer ICD codes billable?

Yes. All five of these ovarian cancer-related ICD-10 codes are valid and billable. Do note that these codes are only meant to be used on female patients.

Clinical information about ovarian cancer

Ovarian cancer is a type of cancer of the female reproductive organs. If a person has ovarian cancer, there is an abnormal growth and multiplication of cells in the ovary. This type of cancer is often difficult to diagnose immediately because it tends to be asymptomatic. More often than not, this cancer would have already made its way to the abdomen before it starts making itself known through the following symptoms:

  • Bleeding in the vagina (especially when it’s not during the menstrual cycle)
  • Discharge of the vagina
  • Having to constantly urinate
  • Pain in the vagina
  • Pain in the pelvis
  • Sudden changes in bowel movement
  • Pain in the abdomen
  • Bloating or enlargement of the abdomen

Synonyms include:

  • Carcinoma of ovary, stage 1
  • Carcinoma of ovary, stage 2
  • Carcinoma of ovary, stage 3
  • Carcinoma of ovary, stage 4
  • Carcinosarcoma of ovary
  • Carcinosarcoma of left ovary
  • Carcinosarcoma of right ovary
  • History of bilateral primary malignant neoplasm of ovaries
  • History of carcinosarcoma of ovary
  • History of malignant neoplasm of female genital organ
  • History of malignant neoplasm of ovary
  • Family history of malignant neoplasm of ovary
  • Family history of malignant neoplasm of ovary in first degree relative
