Commonly asked questions

Given the carcinomatosis, no. There isn’t. There are no ICD-10 codes with peritoneal carcinomatosis in their name, so the ICD-10 code we indicated is the best choice. There is an ICD-10 code for peritoneum cancer (C48.2), but that’s specific to cancer that starts there. In contrast, carcinomatosis results from a pre-existing cancer that has spread to certain areas, so it doesn’t fit that ICD-10 code.

To diagnose this, healthcare professionals will conduct blood tests, imaging tests, and/or biopsies. They might even detect this while performing surgery for another cancer.

It depends on how severe it is, but if a person has this, the person has a severe enough cancer that gave birth to this problem. Treatment for this can be surgical (cytoreductive surgery or peritonectomy). It can also come in the form of hyperthermic intraperitoneal chemotherapy.
