Major Changes in the FY 2025 IPPS Final Rule
To help healthcare providers quickly grasp the most critical updates, here’s a summary of the major changes:
| Key Change | FY 2025 Update | Practical Implication |
|---|---|---|
| IPPS Base Rates | Net 2.9% increase (3.4% market basket – 0.5% productivity) | Overall higher payments, requires precise billing to capture. |
| New Technology Add-on Payments (NTAPs) | Expanded to cover 6 additional devices & procedures | Hospitals can claim additional payments for specific innovative treatments. |
| Outlier Thresholds | Fixed-loss amount raised to $29,000 | Fewer cases will qualify as outliers, demanding careful cost management and documentation. |
| MS-DRG Updates | 23 re-weighted, 4 new DRGs, 2 deleted DRGs | Impact specific service lines, requiring updated coding practices for accurate reimbursement based on the new DRG payment table 2025. |
CMS finalized a net 2.9% increase to IPPS base rates, reflecting a 3.4% market basket update minus a 0.5% multifactor productivity adjustment. [CMS FY 2025 Final Rule]
New technology add-on payments (NTAPs) expanded to cover six additional devices and procedures under CMS-1808-F, including innovations in areas such as gene therapies, advanced wound care technologies, and specific cardiovascular interventions. These additions provide crucial financial support for hospitals adopting cutting-edge treatments. [CMS NTAP Fact Sheet]
Outlier thresholds were recalibrated, raising the fixed‐loss amount to $29,000 for most MS-DRGs. This increase means fewer complex and high-cost cases will qualify for outlier payments, directly impacting hospital revenue cycles. Hospitals must meticulously track costs and ensure robust documentation to justify services for these higher thresholds. It necessitates a proactive approach to revenue cycle management, potentially requiring adjustments to charge master pricing and enhanced claim monitoring. [CMS IPPS Updates]
Official FY 2025 MS-DRG Weights and Payment Tables
Understanding the official FY 2025 MS-DRG Weights and the complete DRG Payment Table 2025 is essential for accurate reimbursement. These updates directly influence how hospitals are paid for inpatient services.
MS-DRG Updates
CMS re-weighted 23 MS-DRGs based on FY 2023 MedPAR data. Notably, four new DRGs were added to specialized oncology care, such as those for CAR T-cell therapy and other advanced immunotherapies, reflecting evolving treatment landscapes. Conversely, two underutilized DRGs were deleted. These adjustments demand that medical coders stay current with the official DRG payment table 2025 and the CMS DRG weights FY 2025 to ensure accurate assignment and optimal reimbursement for inpatient stays.

Accessing the CMS IPPS Pricer for FY 2025
The CMS IPPS Pricer 2025 is an indispensable tool for healthcare providers to estimate Medicare inpatient prospective payments. Effectively utilizing the CMS web pricer 2025 ensures accurate financial forecasting and helps verify expected reimbursements. Here’s a practical guide on how to access and leverage this vital resource:
- Navigate to the official CMS.gov website.
- Use the search bar to look for “IPPS Pricer” or “Inpatient Prospective Payment System Pricer”.
- Locate and select the specific link for the FY 2025 IPPS Pricer or CMS web pricer 2025. This is typically an application or a downloadable file.
- Once accessed or downloaded, input relevant claim data such as the MS-DRG, wage index, geographic adjustment factors, and other case-specific details.
- The pricer will calculate the estimated Medicare payment. Use this information to verify expected reimbursements, identify potential discrepancies, and inform your revenue cycle management strategies. The CMS pricer 2025 is critical for understanding the impact of various payment adjustments.
Common Questions from Billers & Coders in 2025
1. How Do Pre-Entitlement Days Affect IPPS Billing?
“If a patient exhausts Part A benefits mid-stay, how do we bill pre-entitlement days?” [FCSO FAQ]
Answer: Pre-entitlement days are excluded from PPS pricer calculations and not counted toward the 60-day benefit period. Bill using Value Code 09 for SNF days only after entitlement date. [FCSO Resource]
2. What’s Changed with POA Indicator Reporting?
“Are new POA exemptions in effect for COVID-related diagnoses?” [CMS POA Policy]
Answer: Acute-care IPPS discharges still require POA indicators for all principal and secondary diagnoses, with CMS clarifying that codes U07.1 and U09.9 remain exempt until Dec 31, 2025. Exempt diagnoses use a dash (“–”) in FL 67–69 on UB-04. [CMS POA Reporting]
3. How to Navigate the Two-Midnight Rule?
“Has CMS modified the two-midnight benchmark for inpatient admission?” [CMS Two-Midnight Rule]
Answer: The two-midnight framework stands, but CMS encourages clinical documentation specifying physician expectation of ≥2 midnights. Medical review denials persist if documentation lacks rationale. Critical scenarios where physician documentation is paramount include:
- Patient admitted with acute chest pain, observation initially, then physician documents expectation for further inpatient care extending beyond two midnights due to complex diagnostic workup and potential intervention.
- Elderly patient with pneumonia, initially stable, but physician notes high risk of deterioration requiring close monitoring and intravenous antibiotics for an anticipated stay crossing two midnights.
- Post-surgical patient where recovery is expected to be prolonged due to comorbidities, and physician explicitly states the necessity of inpatient care for greater than two midnights for safe discharge.
4. What Are the New Outlier Thresholds?
“Why are more cases qualifying as outliers in Q1 2025?” [CMS Outlier Details]
Answer: The fixed-loss amount rose to $29K, raising cost volume necessary to trigger outlier payments. Review cost reports to adjust thresholds and monitor DSH ratio impacts. [CMS Source]
5. How to Bill for Drug-Shortage Separate Payments?
“Can we bill Part A for buffer stock purchases?” [CMS NTAP Rule]
Answer: Under CMS-1808-F, small independent hospitals may receive separate Part A payments for essential drug buffer stock purchases. Submit via separate line item with HCPCS code C9399 and modifier TS. [CMS Instruction]
Appeals & Compliance Best Practices
Appealing DRG Downgrades
Document comorbidities with POA “Y” and submit physician attestation if coding disputes arise. Include discharge summaries and lab results. [AHIMA Appeals Guide]
Avoiding Upcoding Scrutiny
Health Affairs reports upcoding growth of 67% in highest severity MS-DRGs. Conduct regular audits of POA and MCC assignments to mitigate RAC audits. [Health Affairs Report]
