Coverage assessment is based on indication-specific criteria documented by the provider. The form collects the following conditional elements used to determine medical necessity:
Breast cancer (HER2+): For breast cancer, confirm human epidermal growth factor receptor 2 (HER2)-positive disease; specify whether use is neoadjuvant/adjuvant for >= T2 or >= N1 early stage or locally advanced disease or for recurrent/stage IV disease; if neoadjuvant/adjuvant, confirm Perjeta will be given in combination with trastuzumab AND either docetaxel or paclitaxel; document whether the patient has been previously treated for this diagnosis and if previously treated, indicate whether Perjeta will be used in combination with trastuzumab when prior therapy included chemotherapy and trastuzumab in the absence of prior Perjeta.
Form contains checkboxes for each conditional item.
Colorectal cancer (CRC): For CRC, document unresectable advanced or metastatic disease and HER2-amplified disease; indicate whether Perjeta will be given as subsequent therapy in combination with trastuzumab; confirm tumor is RAS wild-type and document prior HER2 inhibitor exposure and prior chemotherapy history including whether patient received oxaliplatin-based or irinotecan-based regimens as queried on the form.
Multiple conditional questions capture prior regimen exposures (oxaliplatin, irinotecan, FOLFOXIRI, fluoropyrimidines).
Appendiceal cancer: For appendiceal cancer, document HER2-amplified disease and that tumor is RAS and BRAF wild-type as requested; indicate whether Perjeta will be given as subsequent therapy in combination with trastuzumab and whether patient previously received a HER2 inhibitor.
Form contains specific yes/no items for appendiceal cancer.
Biliary tract cancer: For biliary tract cancer, indicate whether Perjeta will be given as subsequent therapy in combination with trastuzumab and confirm progression on or after systemic treatment for unresectable or gross residual (R2) disease or metastatic HER2-positive disease (IHC3+/ISH+/NGS amplification) as queried on the form.
Specific progression and HER2-status questions are on the form.
Salivary gland / head and neck cancer: For salivary gland or head and neck cancer, document planned combination with trastuzumab when applicable, confirm use as systemic therapy for HER2-positive recurrent disease with distant metastases when indicated, and document performance status (PS 0-3) per form items.
Form asks performance status and combination therapy questions.
Brain metastases in HER2-positive breast cancer: For brain metastases in HER2-positive breast cancer, indicate whether Perjeta will be given in combination with high-dose trastuzumab as treatment per the form.
Form includes a specific question about combination with high-dose trastuzumab.
Other indications: For all other indications, document the requested indication and provide HER2 status, prior therapies, and any other condition-specific information requested on the form to support medical necessity.
Form includes a checkbox for ‘All other indications or diagnoses’ and space for additional pertinent information.
