Centers for Medicare and Medicaid Services (CMS) Proposed Rule for the Inpatient Prospective Payment System (IPPS)

On Tuesday, April 24, 2018, the Centers for Medicare and Medicaid Services (CMS) released a draft of hospital payment levels proposed for patient discharges after October 1, 2018. The April 2018 Proposed Rule for the Inpatient Prospective Payment System (IPPS) update includes ICD-10 coding and assignment of percutaneous Impella implantation to MS-DRG 215 for Other Heart Assist System Implant. The Proposed Rule also maintained bi-ventricular Impella support in MS-DRG 1-2 assignments, and Impella hospital transfer and support in MS-DRG 268-269 for the receiving hospital.

Proposed new payment levels for all hospital MS-DRGs, including those most relevant to Impella related procedures, are in Table A. Impella related procedures were previously assigned to MS-DRG 216-221 for assistance in the catheterization lab only, and were reimbursed at a lower rate than MS-DRG 215 and MS-DRGs 1-2. The final rulemaking may differ substantially from this proposal and will take effect October 1, 2018. The MS-DRG 215 proposed rate is lower than the previous year based on the CMS process to evaluate hospital charges, length of stay, patient comorbidities and takes into effect hospital efficiencies over the prior year.

The American Hospital Association (AHA) and CMS have completed a system of care around the utilization of percutaneous heart pumps. A designated DRG 215 code will simplify coding and enable hospitals to receive payment in multiple settings and indications. This IPPS update also reflects the recent expansion of Impella indications from the U.S. Food and Drug Administration for High Risk Percutaneous Coronary Intervention, Cardiogenic Shock, and Bi-Ventricular Support.

The Proposed Rule for the Inpatient Prospective Payment System (IPPS) is available on the CMS website at cms.gov and is open for public comment until June 25, 2018.
