The FY 2027 Inpatient Prospective Payment System (IPPS) Proposed Rule includes several updates that could affect hospital reimbursement, coding, documentation, and operational planning.
While many organizations may first focus on the proposed 2.4% operating payment increase, the rule also includes notable changes to MS-DRGs, ICD-10-CM/PCS codes, CC and MCC designations, quality reporting, and new technology payments. Although payment updates often receive the most attention, these operational changes frequently require the greatest amount of planning, education, and implementation before the October 1 effective date.
What’s Proposed?
CMS is proposing to create 14 new MS-DRGs and delete 18 existing MS-DRGs, with several changes tied to cardiac device procedures, spinal fusion, hip and knee revisions, and emerging technologies. The proposed MS-DRG revisions appear intended to more closely align payment classifications with the resources hospitals use to care for increasingly complex patients.
The Proposed Rule also includes 184 new ICD-10-CM diagnosis codes, four revised codes, and one new ICD-10-PCS procedure code. Many of these proposed changes focus on greater specificity, including osteomyelitis, pregnancy-related diagnoses, BMI reporting, neoplasms, and musculoskeletal conditions. For coding and CDI teams, these updates reinforce the need for accurate, detailed documentation.
CC and MCC changes are another important area to watch. CMS is proposing three additions to the MCC list, 56 additions to the CC list, and 22 deletions from the CC list. Several social determinants of health Z codes are proposed for removal from the CC list, signaling CMS’s continued focus on resource utilization tied directly to the underlying medical condition.
New technology payments are also a key part of the Proposed Rule. CMS proposes continuing New Technology Add-on Payments for 41 technologies, discontinuing 13, and reviewing additional applications for FY 2027. The agency is also proposing to eliminate the alternative NTAP pathway beginning in FY 2028.
How To Prepare?
Although the Final Rule will determine which proposals are ultimately adopted, hospitals should begin reviewing the areas most likely to affect their organization now. MS-DRG changes, ICD-10 updates, documentation needs, quality reporting, and new technology payment policies may all require education, workflow updates, and cross-department planning before the October 1 effective date.
For organizations looking for deeper analysis after the Final Rule is released, the 2027 IPPS Masterclass is a comprehensive 3-part webcast series designed to break down the most important FY 2027 changes and explain their real-world impact.
