Hyperthermic Intraperitoneal Chemotherapy for Select Intra-Abdominal and Pelvic Malignancies

Effective date
Not stated in the notice
Identified
Jun 20, 2026

Summary

Cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy (HIPEC) at the time of surgery may be considered medically necessary for pseudomyxoma peritonei and diffuse malignant peritoneal mesothelioma. For newly diagnosed epithelial ovarian or fallopian tube cancer, HIPEC at interval cytoreductive surgery may be considered medically necessary only when all listed criteria are met: stage III disease, ineligibility for primary cytoreductive surgery (or incomplete surgery followed by neoadjuvant chemotherapy and interval debulking surgery), and expected complete or optimal cytoreduction. HIPEC in all other ovarian cancer settings, including stage IIIC or IV, cytoreductive surgery plus HIPEC for peritoneal carcinomatosis from colorectal, gastric or endometrial cancer, and all other indications, including goblet cell tumors of the appendix, are considered investigational.

What to do

Action · 5 steps
01Billing team: Bill intraoperative HIPEC for pseudomyxoma peritonei or diffuse malignant peritoneal mesothelioma as medically necessary only when the record documents that the service meets the policy's medical necessity criteria.
02For ovarian or fallopian tube cancer, document all three criteria before billing HIPEC: stage III disease, ineligibility for primary cytoreductive surgery or incomplete surgery followed by neoadjuvant chemotherapy and interval debulking surgery, and expected complete or optimal cytoreduction.
03Use CPT 96547 for the first 60 minutes and CPT 96548 for each additional 30 minutes of the intraoperative HIPEC procedure, which list separately in addition to the primary procedure code.
04Do not bill HIPEC for colorectal, gastric or endometrial peritoneal carcinomatosis, or for other ovarian cancer settings as medically necessary, because the policy treats them as investigational.
05BCBSMS makes no payment for services not documented to be medically necessary.
