Medicare’s 2027 Orthopedic Split Screen

by Michael N. Brown

Surgeon Payments Fall While Facility Rates Rise

The final rules create a margin-migration problem, not a simple rate update. Orthopedic groups and health systems must evaluate professional reimbursement, facility economics, surgeon compensation, documentation and site of service together.

One surgery. Two claims. Opposite financial directions.

That is the central story emerging from Medicare's final 2027 payment rules.

Beginning January 1, 2027, Medicare will reduce physician reimbursement for several high-volume orthopedic procedures, with primary hip and knee replacements among the most affected. Meanwhile, qualifying hospital outpatient departments and ambulatory surgery centers will receive a 2.3% general payment update. Qualifying inpatient hospitals are also receiving a 2.3% update under the federal fiscal-year payment system. www.cms.gov

These policies do not cancel each other out. They apply to different claims, different payment systems and, frequently, different organizations.

A health system may collect more on the facility claim while collecting less for the surgeon's work. An independent orthopedic practice may experience the professional reduction without participating in any facility-side increase. An organization that shifts appropriate cases to an ASC may improve facility economics while its surgeons continue to face lower professional reimbursement.

The result is not simply a Medicare cut or increase. It is a redistribution of orthopedic margin.

The orthopedic procedures Medicare revalued

CMS adopted the following work relative value units for 2027 joint arthroplasty:

Procedure	CPT	2026 work RVUs	2027 work RVUs	Change
Total hip replacement	27130	19.11	16.70	−12.6%
Total knee replacement	27447	19.11	16.70	−12.6%
Total shoulder replacement	23472	21.58	19.35	−10.3%
Shoulder hemiarthroplasty	23470	17.44	15.60	−10.6%

These figures show only the work-RVU component of Medicare payment. They do not represent the full professional fee, which also includes practice-expense and malpractice RVUs, the conversion factor and geographic adjustments.

The final reductions are smaller than CMS initially proposed, but they remain substantial. They also follow a reduction of more than 7% in Medicare surgical fees for hip and knee replacement during 2026, according to the American Association of Hip and Knee Surgeons. www.aahks.org

The work-RVU reduction is only one part of the calculation. For physicians who are not qualifying participants in an Advanced Alternative Payment Model, the Medicare conversion factor will fall from $33.40 in 2026 to $32.63 in 2027, a 2.31% decrease. The qualifying APM conversion factor will fall 1.83%, from $33.57 to $32.95. The expiration of a one-year statutory increase provided for 2026 is a major reason for the decline.

When the lower work RVU and lower nonqualifying conversion factor are combined, the physician-work component of a primary hip or knee replacement falls from approximately $638 to $545 per case before geographic adjustment, a reduction of about 14.6%.

That calculation does not represent the entire professional payment. Nevertheless, it illustrates the direction and magnitude of the pressure.

For a joint-replacement surgeon performing 300 Medicare hip and knee procedures annually, the work-component difference alone approaches $28,000 before considering practice-expense changes, contractual effects or changes to other services.

Office-based orthopedics faces a second reduction

The operating room is not the only source of exposure.

CMS also finalized a new payment policy for a separately identifiable office or outpatient E/M visit furnished on the same day as a procedure carrying a 0-day global period.

Beginning January 1, 2027:

• The highest-valued service will be paid at 100%.
• The lower-valued same-day E/M service or procedure will be paid at 80%.

This new 20% payment reduction applies only to procedures with a 0-day global period.

CMS originally proposed applying the policy to procedures with 0-, 10- and 90-day global periods. After reviewing industry comments, CMS excluded procedures with 10- and 90-day global periods from the final payment-reduction policy. www.cms.gov

The final rule is therefore considerably less severe than the original proposal, but it still creates a meaningful payment reduction for common encounters such as a medically necessary office visit performed with a same-day joint injection.

What the exclusion of 10- and 90-day procedures means

Excluding 10- and 90-day procedures from the new payment reduction does not change Medicare's existing global-surgery coding requirements.

Under those longstanding requirements:

• For 0- and 10-day minor procedures:Modifier 25 may be appended to an E/M service when the documentation supports a significant, separately identifiable service above and beyond the work inherent in the procedure.
• For 90-day major procedures:Modifier 57 may be appended when the E/M service results in the initial decision to perform the major surgery, generally on the day of or day before surgery.

Modifier 57 does not apply to every E/M service associated with a 90-day procedure. Other routine preoperative E/M services are generally included in the global surgical payment. www.cms.gov

A clearer path to payment is not automatic permission to bill

There is a positive operational aspect to the final policy.

CMS now provides a clearer national payment pathway for a qualifying E/M service and a 0-day procedure furnished on the same date. Practices that have historically encountered automatic denials or difficult appeals for these combinations may have a better opportunity to receive payment when the claim is correctly coded and fully supported.

The policy does not eliminate payer edits or guarantee payment, but it gives compliant practices a stronger basis for payment and, when necessary, appeal.

Just as important, the policy does not mean that every office visit performed with an injection is separately billable.

A minor procedure already includes an inherent E/M component, the usual pre-procedure, intra-procedure and post-procedure work associated with performing it. Medicare also considers the decision to perform a minor procedure part of the procedure payment.

To report a separate E/M service with modifier 25, the medical record must demonstrate a significant, separately identifiable service above and beyond the work already included in the minor procedure.

A different diagnosis is not required. However, the documentation must make the additional assessment, medical decision-making and plan distinguishable from the work inherent in the injection or other minor procedure.

This creates two separate risks:

• If the documentation does not support work above and beyond the procedure's built-in E/M value, the E/M service may remain nonpayable.
• If the documentation fully supports modifier 25, Medicare may still reduce the lower-valued service by 20% when it is performed with a 0-day procedure.

Strong documentation is therefore necessary to establish separate payment, but even excellent documentation will not prevent the new payment adjustment.

Why the facility increase does not offset the professional reduction

At first glance, Medicare's facility updates appear more favorable.

CMS finalized a 2.3% update for qualifying hospital outpatient departments and ASCs in 2027. The same percentage applies to qualifying inpatient hospitals for federal fiscal year 2027, although the inpatient and outpatient systems operate on different effective-date calendars.

But the 2.3% figures are base updates, not guarantees that every facility or orthopedic procedure will receive exactly 2.3% more. Service-specific weights, quality-reporting status, wage adjustments and other payment policies still affect the result.

For ASCs, the service-level economics of major joint replacement may be more favorable than the general update suggests. Analysis of CMS's final rate files indicates approximate ASC payment increases of:

• 4% for total knee replacement
• 5% for total hip replacement
• 7% for total shoulder replacement

Device-intensive procedures can move differently from the overall ASC update because of the way device costs and ASC payment weights are calculated.

That creates a strategic split.

The surgeon's professional reimbursement can decline regardless of whether the operation occurs in a hospital or an ASC. The facility economics, however, can vary significantly by site.

For health systems, the more useful questions are:

• Which part of the episode gained or lost revenue?
• Which entity receives each payment?
• Where will clinically appropriate cases be performed?
• Does the organization own or participate in the ASC?
• How do the professional and facility changes affect the total economics of the orthopedic service line?

Four areas of immediate financial exposure

1. Independent orthopedic groups

Joint-heavy practices with substantial Medicare volume face the most direct pressure.

Surgical staffing, malpractice coverage, technology, compliance, revenue-cycle operations and office overhead do not automatically decline when Medicare lowers a procedure's RVUs. In the near term, much of that cost structure is fixed, so lower collections can flow quickly to practice margin.

Practices should also determine whether Medicare Advantage and commercial contracts reference the current Medicare fee schedule, a historical fee schedule or a proprietary schedule. A Medicare change can extend beyond traditional Medicare, but only if the contract language permits it.

1. Employed physician enterprises

Health systems employing orthopedic surgeons may absorb lower professional collections while maintaining existing salary guarantees, compensation rates or recruitment commitments.

If surgeon compensation remains unchanged while professional revenue declines, the required practice subsidy increases. The facility may still perform well, but that does not eliminate the financial pressure within the employed medical group.

Leaders should avoid evaluating orthopedic professional operations and facility operations in isolation. They are separate financial statements describing the same clinical enterprise.

1. Surgeon compensation

Organizations using current-year work RVUs in productivity compensation may see surgeons receive less productivity credit for performing the same procedures.

Other groups may continue crediting historical RVUs or fixed internal values. In those organizations, physician compensation may remain stable while Medicare revenue falls, widening the gap between compensation expense and professional collections.

Neither approach should be changed without careful contractual and physician-relations review. But every affected organization should calculate the result before 2027 begins.

1. Site-of-service strategy

The ASC increases make site of service even more consequential.

When clinically appropriate cases move from the hospital to an ASC, the total economic effect depends heavily on ownership. A health system or physician group with an ASC interest may retain a portion of the facility contribution margin. An organization without such participation may simply lose cases and facility revenue.

The answer is not to move every possible procedure. Patient selection, clinical capability, payer authorization, implant cost, capacity, ownership rules and quality must remain central.

But site-of-service strategy is now inseparable from revenue strategy.

What orthopedic leaders should do before January 1

National averages will not reveal the effect on an individual organization. The only reliable answer is to model its actual utilization, contracts, documentation patterns and sites of service.

A practical readiness plan should include seven steps:

1. Reprice the trailing 12 months of professional claims.Apply the 2027 work RVUs, applicable conversion factor and geographic adjustments by CPT, provider and payer.
2. Separate professional and facility effects.Create distinct models for surgeon reimbursement, hospital inpatient payment, hospital outpatient payment and ASC payment.
3. Identify modifier 25 exposure.Measure the volume and value of office E/M services billed with 0-day procedures, including common injection combinations.
4. Audit the documentation, not only the modifier.Confirm that sampled records demonstrate a significant, separately identifiable E/M service above and beyond the work inherent in the minor procedure. Verify that claim edits neither add modifier 25 automatically nor suppress it indiscriminately.
5. Review payer contracts.Determine which agreements use current-year Medicare rates, frozen Medicare schedules, percentages of Medicare or proprietary fee schedules.
6. Model compensation consequences.Compare the effects of adopting 2027 RVUs, retaining historical RVUs and maintaining current compensation-per-RVU rates.
7. Evaluate site-of-service scenarios.Estimate the professional and facility margin implications of clinically appropriate cases remaining in the hospital or moving to an ASC.

The most useful output is not a single percentage. It is a management model showing the change in revenue and margin by procedure, payer, surgeon, location and legal entity, and a documentation review that distinguishes compliant modifier 25 use from E/M work already included in a minor procedure.

The larger lesson is to manage the episode, not the headline

Medicare's 2027 rules expose a weakness in the way many organizations evaluate reimbursement.

Professional revenue teams monitor the Physician Fee Schedule. Hospital finance teams monitor IPPS and OPPS. ASC leaders review their own rates. Managed-care teams interpret contracts. Physician compensation committees evaluate work RVUs.

Each group may understand its own numbers while the organization misses the combined economic picture.

Orthopedic reimbursement can no longer be managed as a collection of separate payment updates. It must be managed as an episode of care spanning the physician practice, hospital, ASC, payer contract and compensation plan.

The organizations best prepared for 2027 will not merely know that rates changed. They will know precisely where margin is moving, when a same-day E/M service is truly separate from a minor procedure, and how to align budgets, contracts, compensation structures, coding workflows and site-of-service strategy before the first affected claim is submitted.

At Fellow Health Partners, we help orthopedic practices, ASCs and health systems translate payment rules into practice-specific financial and operational plans. That begins with the organization's actual CPT, modifier, provider, payer, documentation and site-of-service data, not a national average.
