Centers For Medicare & Medicaid Services Creates New Hospital Inpatient Payment for Coronary Intravascular Lithotripsy

August 2, 2023 at 8:00 AM EDT
Three New IVL-Specific Diagnostic Related Groups (DRGs) with Increased Payments Go Into Effect October 1, 2023

SANTA CLARA, Calif., Aug. 02, 2023 (GLOBE NEWSWIRE) -- Shockwave Medical, Inc. (NASDAQ: SWAV), a pioneer in the development and commercialization of transformational technologies for the treatment of cardiovascular disease, announced today that as part of the Fiscal Year 2024 Medicare Hospital Inpatient Prospective Payment System (IPPS) final rule, the Centers for Medicare & Medicaid Services (CMS) has created new Medicare Severity Diagnosis Related Group (MS-DRG) codes and payments for coronary Intravascular Lithotripsy (IVL) in the hospital inpatient setting. The new MS-DRG codes and payments will become effective October 1, 2023.

Three new codes, MS-DRGs 323, 324, and 325, have been created to describe Percutaneous Coronary Interventions (PCI) that utilize coronary IVL, with and without a stent implant (intraluminal device), in the hospital inpatient setting. The new coronary IVL-specific MS-DRGs are associated with higher payments than the MS-DRG payments for other Percutaneous Coronary Intervention (PCI) procedures.

The relevant codes are as follows:

MS-DRG Descriptor Payment2
323 Coronary Intravascular Lithotripsy with Intraluminal Device with MCC1 $28,987
324 Coronary Intravascular Lithotripsy with Intraluminal Device without MCC1 $20,785
325 Coronary Intravascular Lithotripsy without Intraluminal Device without CC/MCC1 $18,514

1 MCC: Major Complications and Comorbidities; CC: Complications and Comorbidities.
2 CMS-1785-F; National Average MS-DRG rates shown are based on Medicare Inpatient Prospective Payment System FY2024 Final Rule, National average payment rates assume full update amount for hospitals which have submitted quality data and hospitals have a wage index greater than 1. Site specific payment rates will vary based on regional area wage differences, teaching hospital status, indirect medical education costs, quality data, additional payments to hospitals that treat a large percentage of low income patients (“disproportionate share payments”), etc.

To date, hospitals in the U.S. have been reimbursed for coronary IVL via a New Technology Add-On Payment (NTAP), which provides an incremental payment of up to $3,666 in addition to the relevant MS-DRG payment for a PCI procedure performed in a hospital inpatient setting. The NTAP for coronary IVL will expire on September 30, 2023. In keeping with procedure, CMS analyzed the relevant data collected on coronary IVL under the NTAP program in order to determine how to best code and pay for coronary IVL going forward. CMS first proposed these new MS-DRGs in April via the Fiscal Year 2024 Proposed IPPS, which, following a 60-day public comment period, has now been finalized.

"We appreciate CMS' decision to create new MS-DRGs for coronary IVL. We believe these new MS-DRGs, which are the first new additions in the field of PCI in over 20 years, will help ensure access to the safe and effective benefits of Shockwave IVL for patients suffering from complex, calcified coronary artery disease," said Robert Fletcher, Senior Vice President of Marketing and Market Access at Shockwave Medical. "Having appropriate reimbursement for hospitals is key to ensuring that physicians are able to choose the optimal calcium modification strategy for patients undergoing a PCI. We would like to acknowledge CMS for their thorough evaluation of the NTAP program for coronary IVL and for their thoughtful conclusion on a permanent reimbursement structure.”
