Reviewed by [Christian Espinosa, Founder, Blue Goat Cyber](/authors/christian-espinosa) Last reviewed May 5, 2026 ## Definition IPPS pays acute-care hospitals a predetermined rate per discharge based on the assigned [MS-DRG](/terms/ms-drg). The annual IPPS rule updates rates, NTAPs, and DRG reassignments - closely watched by MedTech. What the regulation says The Inpatient Prospective Payment System (IPPS) is a Medicare payment system for acute care hospitals, established by the Centers for Medicare and Medicaid Services (CMS). It sets predetermined payment rates for inpatient stays based on Diagnosis-Related Groups (DRGs), as outlined in 42 CFR Part 412, Subpart D. Each year, CMS publishes a proposed and then a final rule updating payment rates, policies, and DRG classifications, which directly impacts hospital reimbursement for services, including those utilizing MedTech products. ## What this means in practice Comments to the annual IPPS proposed rule are a key advocacy lever for new device coverage and payment. ## Examples - A MedTech company develops a novel surgical implant, and successful advocacy during the IPPS rulemaking process leads to its inclusion in an existing MS-DRG with an appropriate weighting, ensuring adequate hospital reimbursement. - A new diagnostic imaging device receives a New Technology Add-on Payment (NTAP) designation, providing hospitals with additional reimbursement for its use in qualifying cases for a limited period. - A hospital meticulously documents the severity of a patient's condition and the specific procedures performed, leading to assignment to a higher-paying MS-DRG for a complex MedTech-enabled surgery. Common pitfalls - • Hospitals might not fully understand the specific documentation requirements for optimal MS-DRG assignment, potentially leading to under-reimbursement. - • MedTech manufacturers may over-estimate the impact of a new technology add-on payment (NTAP) without considering the broader IPPS payment structure. - • Failing to engage in the annual IPPS rulemaking process can result in missed opportunities for advocating for appropriate reimbursement of innovative devices. - • Misinterpreting the nuances of DRG assignments can lead to inaccurate financial forecasting for MedTech products used in inpatient settings. ## Frequently asked questions How does IPPS affect MedTech companies? IPPS directly influences the adoption and market access of MedTech products by determining how much hospitals are reimbursed for procedures where these devices are used. Favorable DRG assignments or New Technology Add-on Payments (NTAPs) can significantly improve product uptake. What are MS-DRGs? What is the significance of the annual IPPS rule? How do New Technology Add-on Payments (NTAPs) relate to IPPS? ## Related terms Grouped by theme ### Editor's picks · Hand-selected related concepts [ Reimbursement MS-DRG(MS-DRG) Medicare's inpatient hospital payment classification system. ](/terms/ms-drg)[ Reimbursement New Technology Add-On Payment(NTAP) Supplemental Medicare payment for inpatient use of qualifying new technologies. ](/terms/ntap) ### More in Reimbursement · Same category [ Reimbursement 340B Drug Pricing Program(340B) Federal program providing discounted drugs to safety-net providers. ](/terms/340b)[ Reimbursement Ambulatory Payment Classification(APC) The Medicare grouping system that determines hospital outpatient payment amounts under OPPS, analogous to MS-DRGs for inpatient. ](/terms/apc)[ Reimbursement ASC Site-of-Service Shift Migration of procedures from hospitals to ambulatory surgery centers. ](/terms/asc-shift)[ Reimbursement Budget Impact Model(BIM) Financial model that estimates the total cost consequences of adopting a new technology to a payer's budget over a defined horizon. ](/terms/budget-impact-model) Cited by Where this term appears across MedTech Terms.
