Andexanet alfa (Andexxa) is the first reversal agent for direct factor Xa inhibitors. It qualified as a new, novel therapeutic for the New Technology Add-on Payment (NTAP) reimbursement from the Centers for Medicare and Medicaid Services (CMS) in October 2018. This paper is the first analysis of a healthcare system (HCS) reporting its implementation and utilisation of the NTAP for a new therapeutic. The number of patients treated with Andexxa at the level 1 trauma centre of southern New Jersey, Cooper University Hospital (CUH) was analysed. This paper highlights the successful implementation of Andexxa as a treatment option for (non)traumatic intracranial haemorrhage and acute, nongastrointestinal haemorrhage requiring surgical management at CUH. This paper looked at how well CUH obtained the Andexxa NTAP from CMS for Medicare patients. During the 4-year reimbursement period, CUH treated a total of 88 patients with Andexxa, of which 53 were Medicare patients treated before the expiry of the Andexxa NTAP. The study found that CUH received NTAP for 81 per cent of Andexxa-treated Medicare patients and that CUH received the maximal NTAP amount of US$18,281.25 for 43 per cent of those same patients. The paper discusses how a large trauma centre implemented and received the NTAP for Andexxa and evaluates the effect of cost on reimbursement amounts during the Andexxa NTAP period. Finally, this paper should help healthcare providers, stakeholders and administrators better understand the process through which to obtain NTAP reimbursements from CMS and improve their HCS with new, innovative therapies for their patients.
