What if your biggest reimbursement challenge isn’t the claims that are getting denied, but the ones being paid?
It’s exactly what a lot of orthopedic CFOs and revenue cycle leaders are dealing with now. Claims are moving through. Denials aren’t increasing. Collections look solid on paper. Yet reimbursement keeps declining because site-neutral payment policies are shifting the way Medicare and commercial payers handle outpatient claims.
The problem doesn’t jump out at you as a denial or an error. Instead, you quietly get paid less for the same work.
A recent study conducted by FTI consulting, based on recommendations made by the Medicare Payment Advisory Commission, has shown that expanding site-neutral Medicare cuts would cost over $182 billion over the next 10 years. As noted in the report, such cuts would put more than 1200 hospitals in danger of suffering financially and face limiting hospital services to patients.
At this point, it’s not about “if” site-neutral payments will affect orthopedic billing and reimbursement. The real questions are: How much will it cut into your financial performance, and will you identify it before it starts affecting your margins?
Let’s break down what’s actually changing, where you need to watch for financial risks, and what orthopedic leaders can do right now to stay ahead.
What Site-of-Service Policy Actually Means in 2026?
Site-of-service refers to how Medicare and other commercial payers reimburse differently for the same procedure, depending on where the care is delivered.
These payment differences comes from separate reimbursement systems:
- Hospitals bill through the Hospital Outpatient Prospective Payment System (OPPS),
- Physician offices use the Physician Fee Schedule (PFS), and
- Ambulatory surgery centers follow their own payment rules.
Historically, HOPDs receive higher reimbursements than physician offices or surgery centers, even for similar outpatient procedures.
The move toward site-neutral payments for commercial payers and patients could save $10.8 billion, but that has ripple effects. State-level hospital margins would decline modestly, but it’s big enough to notice.
According to the National Hospital Flash Report, hospital systems reported a 7 to 12% recovery in operating margins.

Why Is CMS Accelerating Site-neutral Reimbursement?
CMS isn’t treating site-neutral reimbursement as a temporary experiment. It’s part of a broader long-term effort to reduce Medicare outpatient spending. The reasoning is straightforward.
If clinically equivalent procedures can be performed safely in lower-cost outpatient settings, CMS wants reimbursement to reflect that efficiency.
From Medicare’s perspective, paying significantly different rates for the same outpatient procedure depending on location creates unnecessary spending variation.
That’s why MedPAC and CMS continue advocating for expanded site-neutral payment policies across:
- Off-campus HOPDs
- outpatient clinic visits
- drug administration services
- procedural outpatient care
- physician office settings
Orthopedic practices are heavily exposed because so many musculoskeletal procedures now qualify for outpatient migration.
The more orthopedic surgery shifts toward ambulatory environments, the more reimbursement pressure hospital outpatient models face.
Back in 2019, CMS started leveling the playing field, rolling out site-neutral payments for clinic visits at all off-campus HOPDs, including those that were previously protected from these BBA’s statutory reforms.
Now, with the proposed 2026 OPPS rule, the trajectory continues. Site-neutral payments will extend to drug administration services at those excepted off-campus HOPDs.
For years, orthopedic practices benefitted from those higher hospital reimbursements, especially for high-volume procedures like:
- Total knee arthroplasty
- Total hip arthroplasty
- Arthroscopy procedures
- Rotator cuff repair
- Spine and small joint surgeries
But CMS is actively trying to reduce these payment gaps.
One step in attempting to stanch the apparent momentum of site-neutral policies is the release of a new report that finds recommended approaches would cut hospital payments by $182 billion over 10 years, including nearly $12 billion in the first year.
You can see the bigger goal: CMS wants to pay about the same rate for the same service, no matter where the care is delivered, so long as it’s clinically comparable.
For policymakers, that’s about cost-containment, but for orthopedic groups and hospitals, it means margin compression.
Why Orthopedic Groups Face Higher Reimbursement Risk in 2026?
Orthopedics sits directly in the center of this reimbursement transition. Some specialties combine all of the following risk factors simultaneously:
- High Medicare patient volume
- Procedure-heavy revenue mix
- Multi-setting care delivery
- Implant-intensive cost structures
- Large outpatient surgical case volume
- Heavy reliance on ASC and HOPD reimbursement
That creates a perfect environment for site-of-service payment changes to materially affect revenue.
Many orthopedic groups also operate across multiple reimbursement environments simultaneously:
- Physician offices
- Hospital outpatient departments
- Joint venture ASCs
- Independent surgery centers
Each setting now carries increasingly different reimbursement implications.
And because many commercial payer contracts are still indexed against Medicare fee schedules, CMS policy changes don’t stay isolated to Medicare for long.
2026 CMS Reimbursement Changes Orthopedic Practices Need to Know
The reimbursement environment for 2026 did not arise from a single rule.
The reimbursement landscape for orthopedic practices has been influenced by various CMS policy changes that have built on each other to collectively form the current reimbursement environment.
- 2026 Physician Fee Schedule Efficiency Adjustment
The 2026 Physician Fee Schedule Final Rule established an efficiency adjustment, a reduction to 2.5% for procedural and surgical specialty practices. For an orthopedic group this directly reduces high value Medicare surgical revenue.
For an orthopedic group with $5M in Medicare allowable surgical charges, this could result in an approximate reduction of $125,000 in revenue before the impact of denials, underpayments, or any changes in commercial payer contracting are even considered.
The American Medical Association took issue with the “efficiency adjustment” calculation, citing that CMS did not consider current practice cost data that adequately addresses surgical procedure, implant, and overhead cost in the practice cost methodology.
Nonetheless, the reduction has been enacted, thus orthopedic groups are feeling compression on their Medicare surgical revenues without any changes in operating costs.
- Site-Neutral Payment Expansion
In addition to the Physician Fee Schedule reduction, the 2026 OPPS and ASC Final Rule expanded the site neutral payment changes to apply to off-campus provider-based departments (PBDs) where it is projected that hundreds of millions in Medicare savings will result.
More to the point from an operational standpoint, what will result from these site neutral payment expansion changes is that procedures previously reimbursed at higher hospital outpatient rates may begin to be reimbursed more closely to the rates provided by a physician’s office or ASC.
It is important to note that for these changes: The claim will be paid. The claim will be compliant. A denial will not occur. An appeal does not exist.
It simply pays at a lower rate than before. Many orthopedic finance teams have identified revenue loss not through the denial management process, but through the variance reporting process.
- ASC Procedure Expansion
Simultaneously with compressing hospital outpatient payments,CMS continues to drive utilization to ambulatory surgery centers (ASCs).
The 2026 Rules: Established 235 additional procedures to the ASC Covered Procedures List, Added another large number of musculoskeletal and orthopedic surgical procedures to the ASC eligible covered procedures, and Continued phasing out the inpatient-only procedure list.
Orthopedic groups with optimized ASC infrastructure may offset reimbursement compression through improved surgical routing and lower overhead.
But groups without strong ASC billing workflows risk losing revenue during the transition.
CMS projects total OPPS payments to reach approximately $101 billion and total ASC payments to reach $9.2 billion in 2026.
Orthopedic Reimbursement Comparison by Site of Service
| Factor | Hospital Outpatient Department (HOPD) | Ambulatory Surgery Center (ASC) | Physician Office |
|---|---|---|---|
| Medicare Reimbursement Level | Highest historically | Lower than HOPD but improving | Lowest overall |
| Operational Overhead | High | Moderate | Lower |
| Implant Cost Exposure | High | Moderate to High | Limited |
| Outpatient Procedure Eligibility | Broad | Rapidly expanding | Limited procedural scope |
| CMS Policy Direction | Reimbursement compression | Encouraged growth | Stable but limited |
| Site-Neutral Payment Risk | High | Lower | Lower |
| Throughput Efficiency | Moderate | High | Moderate |
| Long-Term Margin Potential | Declining in some markets | Increasing for optimized groups | Limited for surgery-heavy practices |
Why Accepted Claims Are Becoming a Bigger Revenue Risk Than Denials?
In 2026, margin erosion is increasingly happening through accepted claims reimbursed under changing site-of-service payment rules rather than through traditional denial activity.
Traditional revenue cycle management systems were built around denial prevention.
They’re designed to identify:
- Missing modifiers
- Authorization failures
- Coding edits
- Claim rejections
- Filing issues
But site-of-service reimbursement compression doesn’t behave like a denial.
The payment comes through, the claim gets closed and often , the underpayment drops by unnoticed.
Stop Letting Denials Turn into Lost Revenue
Track, appeal, and recover payments instantly with strong denial management.
That’s why orthopedic groups are increasingly finding revenue leakage through reimbursement variance analysis instead of denial analytics.
HOPD vs ASC: Which Site of Service Delivers Better Orthopedic Margins?
One of the biggest reimbursement realities orthopedic groups must understand in 2026 is the widening operational impact of the payment differential between hospital outpatient departments and ambulatory surgery centers.
For years, HOPDs generated materially higher facility reimbursement than ASCs for many orthopedic procedures.
That difference shaped:
- Surgical routing decisions
- Hospital acquisition strategies
- Outpatient expansion planning
- Joint venture ASC investments
- Long-term orthopedic growth models
But CMS has spent the last several years gradually narrowing those payment advantages.
And while the reimbursement gap still exists, the financial assumptions surrounding it are changing quickly.
According to MedPAC data, ASCs typically receive approximately 53% to 56% of comparable HOPD reimbursement for similar procedures.
Historically, that created a strong incentive for hospital outpatient delivery. However, the equation is no longer just about gross reimbursement.
Orthopedic finance teams now have to evaluate:
- Overhead structure
- staffing costs
- implant economics
- throughput efficiency
- payer mix
- scheduling utilization
- case turnaround time
- reimbursement stability
When those variables are modeled together, many procedures may perform more efficiently in ASC environments despite lower reimbursement rates.
That’s especially true for high-volume orthopedic outpatient procedures with predictable workflows.
“The biggest force shaping ambulatory surgical care in 2026 will be the continued shift of many higher-acuity case types into ASCs,” DJ Hill, former CEO of Compass Surgical Partners and the company’s current board chair, said in ASC News’ executive outlook
Which Orthopedic Procedures Are Most Affected by Site-of-Service Payments?
Not every orthopedic procedure is equally affected by reimbursement restructuring.
The greatest exposure tends to exist within high-volume outpatient surgical categories.
These commonly include:
- Total knee arthroplasty
- Total hip arthroplasty
- Arthroscopic procedures
- Rotator cuff repair
- Spine-related outpatient procedures
- Small joint reconstruction
- Musculoskeletal injections and interventions
These procedures generate significant revenue volume across orthopedic organizations.
Even relatively small reimbursement adjustments at the per-case level can create substantial annual margin impact.
That’s why many orthopedic groups are now performing procedure-level profitability analysis by setting.
Where Orthopedic Practices Are Losing Revenue
Traditional RCM systems were built around denial prevention, identifying missing modifiers, authorization failures, coding edits, and claim rejections.
But site-of-service compression doesn’t behave like a denial. The payment comes through, the claim closes, and the underpayment often goes unnoticed.
Most orthopedic margin erosion tied to site-of-service policy happens in four areas.
1. Site-of-Service Mismatches
When procedures are billed under outdated reimbursement assumptions, Medicare may apply lower site-neutral rates automatically.
The result:
- Clean adjudication
- Lower reimbursement
- No denial visibility
Unless the organization benchmarks expected reimbursement by care setting, the shortfall often disappears into payment posting.
2. Incorrect Financial Modeling Across Care Settings
Many practices still assume HOPD reimbursement automatically generates stronger margins.
That assumption is becoming less reliable.
With updated ASC payment methodologies and expanded outpatient eligibility, some orthopedic procedures may now generate stronger net margin in ASC environments when:
- Overhead costs
- Implant expenses
- staffing costs
- reimbursement differentials
are modeled together.
Without procedure-level financial analysis, practices risk routing surgical volume inefficiently.
3. Medicare Advantage Site-of-Service Policies
Medicare Advantage plans increasingly apply their own:
- Site-of-service rules
- Authorization requirements
- Network restrictions
- Payment methodologies
These don’t always align with traditional Medicare fee-for-service reimbursement.
For orthopedic groups with growing MA patient share, this creates a second layer of reimbursement complexity.
4. Commercial Payer Alignment with Medicare
Commercial payers are gradually moving in the same direction as CMS.
State-level site-neutral policy discussions and payer reimbursement redesigns are pushing toward narrower differentials between:
- HOPDs
- ASCs
- physician offices
That means orthopedic groups relying heavily on historical HOPD reimbursement advantages may see long-term commercial margin compression as well.
How Orthopedic ASCs Can Offset Reimbursement Compression
While much of the conversation around 2026 reimbursement focuses on margin pressure, there is also real upside for orthopedic groups positioned correctly.
CMS finalized several ASC-related changes that could benefit orthopedic surgery programs significantly.
Equalized Update Methodology
ASCs will now receive payment updates tied to the hospital market basket methodology instead of relying solely on CPI-based adjustments.
This helps reduce long-term reimbursement growth disparities between ASCs and HOPDs.
Expanded Orthopedic Procedure Coverage
Hundreds of new procedures were added or revised for outpatient and ASC eligibility.
That expansion includes:
- Joint procedures
- Musculoskeletal surgeries
- Spine-related procedures
- Arthroscopy services
This creates more flexibility for orthopedic surgical routing.
Continued Migration Toward Outpatient Orthopedics
CMS is clearly signaling long-term preference for outpatient care delivery.
Orthopedic groups with strong ASC infrastructure may benefit from:
- Lower operating costs
- Faster throughput
- Better scheduling control
- Improved case profitability
But only if reimbursement workflows, coding structures, and financial modeling are aligned correctly.
The Future of Orthopedic Reimbursement Is Already Here
Site-of-service reimbursement policy is not a temporary adjustment.
It represents a structural redesign of outpatient payment strategy across Medicare and eventually the commercial market.
For orthopedic practices, the impact is especially significant because the specialty depends heavily on:
- Outpatient surgical volume
- Multi-setting care delivery
- Medicare reimbursement
- Procedure-based revenue
The biggest risk is not necessarily denials.
It’s reimbursement compression that happens quietly through accepted claims, lower payment differentials, and changing care-setting economics.
The orthopedic groups that protect margins successfully in 2026 and beyond will be the ones that:
- Build setting-specific reimbursement visibility
- Optimize ASC strategy
- model procedure profitability accurately
- restructure billing infrastructure early
- expand analytics beyond denial management
The write-down is quiet.
But the financial impact is very real.
And for orthopedic organizations still measuring revenue cycle management performance through denials alone, the largest reimbursement risk in 2026 may already be happening without visibility.
What a Modern Orthopedic RCM Strategy Should Include?
Orthopedic revenue cycle strategy can no longer focus only on coding accuracy and denial prevention.
The modern orthopedic reimbursement model requires integrated visibility across:
- Site-of-service reimbursement
- procedure profitability
- payer-specific reimbursement rules
- ASC utilization
- Medicare Advantage behavior
- underpayment analytics
- contract modeling
- operational cost alignment
That means orthopedic organizations need stronger collaboration between:
- Revenue cycle leadership
- finance teams
- surgical operations
- ASC management
- payer contracting teams
- compliance leadership
Because site-of-service policy affects all of them simultaneously.
What Orthopedic CFOs and Revenue Leaders Should Do in 2026?
Orthopedic finance teams now need to evaluate overhead structure, staffing costs, implant economics, throughput efficiency, payer mix, scheduling utilization, case turnaround time, and reimbursement stability together, not just gross reimbursement rates.
The organizations responding effectively to 2026 reimbursement changes are treating site-of-service policy as a strategic financial issue rather than an isolated billing problem.
Here are the priorities orthopedic practices should focus on immediately.
Build Setting-Specific Reimbursement Benchmarking
Every high-volume orthopedic CPT code should have:
- Expected reimbursement ranges by setting
- HOPD reimbursement benchmarks
- ASC reimbursement benchmarks
- Physician office benchmarks
Without setting-specific variance tracking, silent underpayments become almost impossible to identify consistently.
Reevaluate Procedure Routing Strategy
Many orthopedic groups need updated financial modeling around:
- ASC migration potential
- Procedure profitability by setting
- Implant cost impact
- overhead allocation
- staffing economics
The highest reimbursement rate does not automatically equal the strongest margin anymore.
Prepare for 2028 NPI Billing Requirements
CMS will require off-campus HOPDs to bill under their own NPIs beginning in 2028.
That means orthopedic organizations should begin:
- Credentialing reviews
- Billing infrastructure restructuring
- payer enrollment planning
- NPI workflow mapping
well before the deadline arrives.
Waiting until 2027 creates unnecessary operational risk.
Audit Commercial Payer Contracts
Orthopedic finance teams should evaluate:
- Medicare-linked fee schedules
- site-of-service reimbursement clauses
- outpatient reimbursement structures
- ASC reimbursement terms
because commercial payer reimbursement models are increasingly following Medicare’s direction.
Expand Variance Analytics Beyond Denials
Denial rate alone is no longer enough.
Orthopedic organizations need reimbursement analytics capable of identifying:
- Accepted claims paid below expectation
- setting-based reimbursement shifts
- underpayment trends by CPT
- ASC vs HOPD payment variance
That visibility is becoming essential for margin protection.
Is Your Orthopedic Practice Winning the Site-of-Service Shift or Falling Behind?
By 2026, orthopedic reimbursement isn’t really about coding or denial management. It comes down to two things: where you deliver care and how effectively you do revenue cycle management.
This shift doesn’t make headlines the traditional revenue cycle disruption does, but it’s more dangerous. Even when claims get paid, those still result in shrinking margins.
Orthopedic groups that’ll make it through aren’t just chasing better collections. They will be the ones that:
- know how site-of-service reimbursements work,
- set clear benchmarks,
- use ASCs smartly,
- overhaul workflows early,
- spot underpayments before the compound, and
- treat reimbursement variance as a core financial orthopedic KPI.
Site-of-service reimbursement isn’t just changing orthopedic billing. It’s altering the economics of outpatient orthopedic care itself.
- Setting-specific reimbursement benchmarking
- ASC profitability analysis
- Underpayment detection
- Payer contract reviews
- Reimbursement variance tracking
- Medicare Advantage reimbursement analysis
