On July 29, 2026, the Centers for Medicare & Medicaid Services issued the Fiscal Year 2027 Inpatient Psychiatric Facility Prospective Payment System Final Rule, CMS-1847-F.
The rule applies to Medicare-certified inpatient psychiatric facilities, including freestanding psychiatric hospitals and qualifying psychiatric units within acute care and critical access hospitals. Most FY 2027 payment provisions become effective for discharges occurring from October 1, 2026, through September 30, 2027.
At first glance, the rule may look like another annual payment update.
It is not.
The FY 2027 rule continues CMS’s gradual movement toward more standardized psychiatric patient data, more structured quality reporting, and greater scrutiny of how high-cost claims are calculated. The payment increase matters. However, the longer-term operational changes may have a greater impact on inpatient psychiatric facilities than the percentage itself.
For psychiatric hospitals, compliance leaders, finance teams, clinical leadership, and health information technology vendors, the real question is not simply, “Are payments increasing?”
The more important question is this:
Is your organization’s documentation, reporting infrastructure, and technology prepared for what CMS is building next?
The FY 2027 Rule at a Glance
CMS finalized several important changes:
A 2.3% update to IPF PPS payment rates
An estimated $60 million increase in total IPF payments
An increase in the federal per diem base rate
An updated fixed-dollar loss threshold for outlier payments
A future facility-level cap on outlier payments
Removal of two quality-reporting measures
Implementation of a standardized IPF Patient Assessment Instrument
New options for submitting assessment data through a CMS web application or FHIR-based APIs
Some changes begin October 1, 2026. Others are being phased in over the next several years.
That distinction matters.
Facilities should not wait for a mandatory reporting date before reviewing their workflows. By the time reporting becomes mandatory, organizations should already have completed their documentation mapping, technology testing, staff education, and validation processes.
FY 2027 IPF Payment Rates Will Increase by 2.3%
For FY 2027, CMS is increasing IPF PPS payment rates by 2.3%.
The increase is based on a projected 2021-based IPF market basket increase of 3.2%, reduced by a 0.9 percentage-point productivity adjustment. CMS estimates that the rule will increase payments to inpatient psychiatric facilities by approximately $60 million compared with FY 2026.
The federal per diem base rate will increase from $892.87 to $912.40 for facilities meeting the IPF Quality Reporting Program requirements.
The electroconvulsive therapy payment per treatment will increase from $673.85 to $688.59. Facilities that fail to meet applicable quality-reporting requirements will receive lower rates because of the required two-percentage-point reduction.
The payment increase is meaningful, but it is slightly lower than the payment updates finalized during the previous two fiscal years.

For FY 2025, CMS updated the payment methodology using more recent patient-level claims and cost information. The agency revised adjustment factors involving principal diagnosis, comorbidities, patient age, and the variable per diem adjustment. CMS also increased the ECT payment per treatment from $385.58 in FY 2024 to $661.52 in FY 2025.
For FY 2026, CMS updated the facility-level adjustment factors for teaching status and rural location using more recent claims and cost information. CMS also removed four quality measures and revised its Extraordinary Circumstances Exception policies.
The FY 2027 rule moves in a different direction.
Rather than significantly redesigning patient-level or facility-level adjustments, CMS is focusing more directly on outlier payment distribution and standardized patient assessment data.
In other words, FY 2025 focused heavily on who the patient is.
FY 2026 focused more on what type of facility is providing the care.
FY 2027 begins placing greater emphasis on how patient information is collected, reported, and electronically transmitted.
That is the quiet shift organizations should be watching.
CMS Is Updating the Outlier Threshold
The IPF PPS includes outlier payments for unusually costly psychiatric stays.
These payments are intended to protect facilities from excessive financial risk when caring for patients whose needs result in exceptionally high costs. CMS compares the estimated cost of a stay with a designated threshold. When costs exceed the applicable threshold, the facility may qualify for an additional payment.
CMS sets the fixed-dollar loss threshold each year with the goal of keeping estimated outlier payments equal to approximately 2% of total IPF PPS payments.
For FY 2027, CMS is increasing the fixed-dollar loss threshold from $39,360 to $40,750.
This means a facility’s estimated cost for a qualifying stay must exceed a higher threshold before an outlier payment becomes available.
Although the threshold adjustment is technical, it can have a practical financial effect. Facilities that routinely treat individuals requiring long stays, intensive staffing, complex medical management, or ECT should evaluate how the new threshold may affect anticipated reimbursement.
A 20% Facility-Level Outlier Cap Is Coming in FY 2028
CMS also finalized a significant reform to the outlier payment system.
Beginning October 1, 2027, an IPF with at least 50 stays during the applicable year will generally be limited to receiving no more than 20% of its total IPF PPS payments through outlier payments.
Facilities with fewer than 50 stays per year will be exempt from the cap.
CMS initially proposed broader application of the cap. After reviewing public comments and additional data, the agency limited the policy to facilities with 50 or more stays and delayed implementation until FY 2028.
CMS explained that a small number of facilities reported exceptionally high costs and received outlier payments on a substantial portion of their claims. According to CMS, some of these costs appeared to be driven by facility-level routine expenses, such as labor, real estate, and overhead, rather than costs unique to an individual patient.
The agency intends the cap to prevent a limited number of facilities from consuming a disproportionate share of the national outlier pool.
CMS estimates that applying the policy only to facilities with at least 50 stays will affect approximately 0.8% of providers in a typical year. CMS also projects that lowering the overall concentration of outlier payments could allow more facilities to qualify for outlier reimbursement.
What facilities should do now
Organizations with significant outlier payment activity should review:
Cost-to-charge ratios
Routine cost allocation
Long-stay utilization patterns
High-cost patient populations
ECT-related expenses
Claims receiving outlier payments
Cost report consistency
Documentation supporting medical necessity and resource intensity
The cap does not begin until FY 2028. However, the data CMS will use to evaluate facility patterns will not magically appear on October 1, 2027.
That data is being created now.
CMS Is Removing Two Quality Measures
Beginning with the calendar year 2026 reporting period and FY 2028 payment determination, CMS is removing the following measures from the IPF Quality Reporting Program:
Alcohol Use Brief Intervention Provided or Offered and Alcohol Use Brief Intervention, SUB-2 and SUB-2a
Tobacco Use Treatment Provided or Offered at Discharge and Tobacco Use Treatment at Discharge, TOB-3 and TOB-3a
CMS concluded that removing the measures would reduce reporting burden while preserving other measures that address similar clinical priorities. For example, CMS retained SUB-3 and SUB-3a because those measures cover a broader population involving both alcohol and substance use disorders.
The removal of a reporting measure does not mean the underlying clinical intervention is no longer important.
Facilities must distinguish between three separate concepts:
A CMS quality-reporting requirement
A clinical standard of care
A facility’s documentation and risk-management expectations
CMS specifically encouraged facilities to continue providing clinically appropriate alcohol and tobacco interventions even when those activities are no longer included in the federal quality measure set.
This is where organizations sometimes get themselves into trouble.
A measure disappears from a reporting dashboard, and someone quietly assumes the clinical obligation disappeared with it.
It did not.
Facilities should revise reporting specifications without prematurely deleting clinically appropriate screening, treatment, education, discharge-planning, or documentation workflows.
The Standardized IPF Patient Assessment Instrument Is the Bigger Story
CMS is implementing the standardized Inpatient Psychiatric Facility Patient Assessment Instrument, commonly referred to as the IPF-PAI.
The instrument was mandated by the Consolidated Appropriations Act of 2023. Its purpose is to establish more consistent patient assessment data across inpatient psychiatric facilities.
CMS will permit facilities to submit IPF-PAI data through two methods:
1. Patient Assessment Reporting Interoperability Tool
CMS is developing a free web-based application called the Patient Assessment Reporting Interoperability Tool, or PARIT.
Facilities will be able to enter and submit required IPF-PAI data through the application without developing their own direct electronic interface.
2. FHIR-Based Application Programming Interfaces
Facilities, EHR vendors, and qualified intermediaries may also submit data using APIs developed around the HL7 Fast Healthcare Interoperability Resources standard.
This will be the first CMS statutory quality-reporting program to use FHIR to support the submission of patient assessment data.
That is not a minor technical footnote.
It signals that CMS is moving psychiatric quality reporting toward structured, interoperable, patient-level data. Instead of relying exclusively on manual abstraction and periodic file submission, future reporting will increasingly depend on whether clinical information is captured consistently and stored in a format that another system can understand.
The IPF-PAI Implementation Timeline
CMS finalized a phased implementation schedule:
October 1, 2027: Voluntary IPF-PAI reporting begins
July 1, 2028: Mandatory reporting begins for the third quarter of calendar year 2028
FY 2030: Data submitted during the third and fourth quarters of 2028 will affect the FY 2030 payment determination
CMS expects PARIT to be available no later than October 1, 2027. The agency also plans to begin PARIT training at least six months before the voluntary reporting period starts.
Organizations therefore have time.
But they do not have time to waste.
The preparation process may require coordination among clinical leadership, quality management, compliance, health information management, nursing, finance, information technology, and the organization’s EHR vendor.
What Inpatient Psychiatric Facilities Should Do Now
Conduct a payment-impact review
Evaluate how the new base rate, wage index, outlier threshold, and other adjustments may affect projected Medicare revenue.
Do not assume the national 2.3% increase will translate into an identical increase for every facility. Geographic wage information, patient characteristics, facility adjustments, quality-reporting compliance, and outlier activity can influence the actual result.
Analyze your outlier payment exposure
Identify how much of your annual IPF PPS reimbursement comes from outlier payments.
Facilities approaching the future 20% limit should investigate the drivers now. Review whether high costs are associated with individual clinical complexity, routine operating expenses, cost-report methodology, or a combination of factors.
Map current documentation to anticipated IPF-PAI elements
Determine where required information is presently collected.
Is it documented in discrete fields? Is it buried in narrative text? Is it duplicated across nursing, medical, social work, and discharge documentation? Does staff interpret the same field differently?
Standardization starts with a shared definition.
Speak with your EHR vendor
Ask whether the vendor plans to support:
IPF-PAI data collection
PARIT-compatible workflows
FHIR-based data submission
Data validation
Error correction
Submission status tracking
Audit trails
Staff testing and training
“We support FHIR” is not a complete implementation plan. Facilities need to know which resources, profiles, fields, and workflows will be supported.
Update the quality-measure crosswalk
Remove retired measures from formal reporting workflows at the correct time.
At the same time, identify which underlying clinical activities should remain part of the organization’s care standards, accreditation obligations, state requirements, or internal risk-management program.
Protect the annual payment update
Facilities that fail to submit required quality data remain subject to a two-percentage-point reduction in their annual payment update.
Reporting readiness is therefore not simply a quality department project.
It is a reimbursement protection strategy.
Frequently Asked Questions
When does the FY 2027 IPF PPS final rule take effect?
Most FY 2027 payment provisions apply to discharges occurring from October 1, 2026, through September 30, 2027. The facility-level outlier cap becomes effective October 1, 2027.
How much will Medicare IPF payments increase?
CMS finalized a 2.3% payment-rate update and estimates that total IPF payments will increase by approximately $60 million in FY 2027 compared with FY 2026.
Will every psychiatric facility receive exactly 2.3% more?
No. The 2.3% figure is the national payment-rate update. The actual financial effect on an individual facility may vary based on its wage index, patient mix, facility characteristics, outlier utilization, quality-reporting status, and other payment adjustments.
What is the FY 2027 federal per diem base rate?
The federal per diem base rate will increase from $892.87 to $912.40 for facilities meeting applicable quality-reporting requirements.
What happens when an IPF does not meet quality-reporting requirements?
An IPF that does not submit required quality data may receive a two-percentage-point reduction to its annual payment update.
What is changing with outlier payments?
The FY 2027 fixed-dollar loss threshold increases from $39,360 to $40,750. Beginning in FY 2028, facilities with at least 50 annual stays will generally be limited to receiving no more than 20% of their total IPF PPS payments through outlier payments.
Are small psychiatric facilities subject to the new outlier cap?
Facilities with fewer than 50 stays during the applicable year are exempt from the finalized 20% cap.
Does removing SUB-2 and TOB-3 mean facilities can stop addressing alcohol and tobacco use?
No. CMS is removing the measures from the federal IPF Quality Reporting Program. The change does not eliminate the need to provide clinically appropriate screening, intervention, treatment, education, or discharge planning.
Facilities should also evaluate state law, accreditation standards, payer requirements, and internal policies before changing clinical workflows.
What is the IPF-PAI?
The IPF-PAI is a standardized patient assessment instrument that inpatient psychiatric facilities will use to report specified patient-level information to CMS.
Will facilities need to purchase new software to submit IPF-PAI data?
Not necessarily. CMS plans to provide the free PARIT web application. Facilities may also work with an EHR vendor or other qualified technology partner to submit data through FHIR-based APIs.
When does IPF-PAI reporting become mandatory?
Voluntary reporting begins October 1, 2027. Mandatory reporting begins July 1, 2028, for the third quarter of calendar year 2028. Data from the third and fourth quarters of 2028 will be considered for the FY 2030 payment determination.
Should facilities wait until 2028 to prepare?
No.
Facilities should begin evaluating clinical workflows, documentation fields, system capabilities, staff responsibilities, and vendor readiness well before mandatory reporting begins.
Waiting until the reporting deadline is how a technology project becomes a compliance emergency wearing sensible shoes.
