Ovarian Cancer ICD-10-CM Codes

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.

2. 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.

3. 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.

4. 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.

5. 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.

• 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
