Why Place of Service Matters Under CMS Guidance in 2026 for Pain and Orthopedic Practices

Calendar Year (CY) 2026 Medicare payment policies finalized by the Centers for Medicare & Medicaid Services (CMS) reinforce a consistent theme across outpatient and professional payment systems: the setting in which care is furnished is inseparable from how that care is paid. For pain management and orthopedic practices operating across physician offices, ambulatory surgery centers (ASCs), and hospital outpatient departments (HOPDs), CMS’s 2026 guidance makes site-of-service alignment a practical requirement for reimbursement accuracy and compliance stability.

CMS does not publish a single “place of service framework.” Instead, site-of-service policy emerges through coordinated changes across the Physician Fee Schedule (PFS), the Outpatient Prospective Payment System (OPPS), and the ASC payment system. In 2026, these changes collectively affect outpatient migration, setting-based payment differentials, and how Medicare evaluates cost structure across care environments.
​
This article consolidates the relevant CMS 2026 policy signals and explains their implications for pain management and orthopedic practices without redefining basic billing concepts or overstating CMS intent.

CMS’s 2026 Policy Context for Site of Service
CMS’s approach to site of service in 2026 reflects a continuation of long-standing payment principles rather than a departure from them. Medicare payment systems have historically distinguished between services furnished in non-facility settings (such as physician offices) and facility settings (such as HOPDs and ASCs). What changes in 2026 is the degree to which CMS operationalizes that distinction across outpatient systems.

Across its final rules, CMS repeatedly emphasizes that:

• Payment should reflect the resources typically required in the setting where care is furnished.
• Beneficiaries should not pay materially more for comparable outpatient services solely because they were delivered in higher-cost environments.
• Payment methodologies should reflect contemporary clinical practice rather than legacy assumptions about care settings.

These principles are not new, but CMS’s 2026 policies expand their application in ways that directly affect outpatient procedural care, particularly in musculoskeletal and interventional service lines.

How CMS Uses Payment Systems to Apply Site-of-Service Logic
CMS applies site-of-service policy indirectly, through payment system design rather than explicit mandates.
Under the Physician Fee Schedule, professional reimbursement differs depending on whether services are furnished in a facility or non-facility setting. In facility settings, CMS assumes that certain practice expenses are borne by the facility and therefore reimburses the professional component differently than in office-based care.

Under OPPS and ASC payment systems, CMS reimburses facilities separately for outpatient services and adjusts payment rates based on statutory authority, cost reporting, and policy objectives. These systems increasingly intersect with PFS logic, particularly where CMS applies site-neutral methodologies.
In 2026, CMS continues to align these systems to reinforce setting-based distinctions rather than blur them.

Expansion of Site-Neutral Payment in Off-Campus Provider-Based Departments
One of the clearest site-of-service signals in CY 2026 appears in the OPPS/ASC final rule, where CMS finalized expansion of its site-neutral payment methodology to include drug administration services furnished in excepted off-campus provider-based departments (PBDs). CMS applies a Physician Fee Schedule–equivalent payment rate for these services when provided in those settings.

This policy builds on CMS’s prior application of site-neutral payment to clinic visits in off-campus PBDs. While drug administration services are the specific focus of the 2026 expansion, the policy logic extends beyond those codes. CMS is reinforcing its position that organizational ownership of an outpatient department does not, by itself, justify higher payment when comparable services can be delivered in lower-cost environments.

For pain and orthopedic practices, the relevance lies not in the specific services affected, but in how this policy influences:

• Health system outpatient strategy
• Payer contracting posture
• Utilization management expectations related to care setting

Practices operating within or alongside provider-based outpatient structures should view this expansion as confirmation that CMS will continue to evaluate outpatient payment through a site-neutral lens where statutory authority permits.

Phase-Out of the Inpatient Only (IPO) List
Beginning in 2026CMS finalized the first phase of a three-year phase-out of the Inpatient Only (IPO) list, beginning in CY 2026 with the removal of 285 procedures, the majority of which are musculoskeletal.
CMS states that advances in medical practice allow many of these procedures to be performed safely in outpatient settings and that removal from the IPO list permits Medicare payment in hospital outpatient settings when clinically appropriate. CMS frames this change as expanding flexibility rather than mandating outpatient migration.

For orthopedic practices, this policy materially changes outpatient eligibility. Procedures that were previously restricted to inpatient payment pathways may now be reimbursed in outpatient environments, subject to clinical appropriateness and payer requirements.

For pain management practices, the IPO phase-out matters indirectly. As orthopedic procedures migrate outpatient, interventional pain services often intersect with perioperative and post-procedural care pathways. This increases the importance of coordination across settings and reinforces the need for consistent site-of-service planning.

ASC Covered Procedures List Revisions
CMS finalized revisions to ASC Covered Procedures List (CPL) criteria in CY 2026, eliminating several general exclusion criteria and reclassifying them as nonbinding physician considerations related to patient safety. As a result, CMS added hundreds of procedures and codes to the ASC CPL, including procedures removed from the IPO list.

These changes expand the scope of outpatient surgical services eligible for ASC reimbursement under Medicare policy. However, CMS does not eliminate payer discretion or override commercial contract requirements. The practical effect is that ASC eligibility expands under Medicare, while operational complexity remains.

For pain management and orthopedic practices with ASC exposure, these revisions increase the importance of:

• Pre-service site selection discipline
• Alignment between clinical planning and authorization workflows
• Monitoring of payer-specific site-of-service policies

Expanded eligibility does not equate to automatic reimbursement across all payers or settings.

Non-Opioid Pain Relief Payment Policies in Outpatient Settings
CMS finalized continuation of statutory temporary additional payments for certain non-opioid treatments for pain relief furnished in HOPD and ASC settings through December 31, 2027. CMS also finalized the list of qualifying drugs and devices that will be paid separately in both settings beginning in CY 2026.
This policy applies specifically to qualifying products identified by CMS and is tied to both product eligibility and outpatient setting. The payment framework is setting-dependent, reinforcing that reimbursement outcomes for pain-related therapies can vary based on where care is delivered.

For pain management practices that furnish qualifying therapies, the policy highlights the need for:

• Accurate alignment between care setting and billing pathway
• Awareness of which outpatient settings support separate payment
• Consistent operational processes to avoid missed reimbursement

This is a targeted policy, but it illustrates CMS’s broader use of outpatient payment systems to shape care delivery and reimbursement patterns.

Practice Expense Methodology Changes Under the CY 2026 PFS
Under the CY 2026 Physician Fee Schedule, CMS finalized updates to practice expense (PE) methodology that recognize differences in indirect costs between office-based and facility-based settings. CMS states that allocating indirect costs at the same rate across settings may no longer reflect contemporary clinical practice patterns.

This change affects how CMS values professional services depending on where they are furnished. For practices that deliver services across multiple settings, changes in PE allocation can shift relative reimbursement without any change to CPT coding or clinical documentation.

For pain management and orthopedic practices operating hybrid models, this reinforces that:

• Professional reimbursement is increasingly sensitive to care setting
• Financial modeling must account for setting-based valuation changes
• Site-of-service decisions have downstream revenue implications beyond facility payment

CMS’s rationale is methodological rather than punitive, but the effect is that setting selection increasingly influences reimbursement outcomes.

How CMS Policy Shapes Payer Behavior
Although CMS policy applies directly to Medicare fee-for-service, it often influences payer behavior more broadly. Medicare Advantage plans and commercial payers frequently reference Medicare payment logic when developing site-of-service programs, utilization management rules, and reimbursement differentials.
CMS’s 2026 policies provide payers with:

• Reinforced justification for site-of-service steering
• Expanded outpatient pathways for musculoskeletal care
• Continued emphasis on aligning payment with care setting cost structure

As a result, pain management and orthopedic practices may experience site-of-service pressure even when billing non-Medicare payers.

Operational Consequences for Pain Management and Orthopedic Practices
CMS’s 2026 guidance does not require new billing codes or documentation formats. Instead, it increases the operational importance of consistency across clinical, administrative, and billing workflows.
Practices should expect that:

• Authorization approvals may be increasingly tied to specific outpatient settings
• Reimbursement variance may occur without outright denials when services are furnished in different settings
• Documentation supporting site selection becomes more important as outpatient eligibility expands

These dynamics apply across payer types and care environments.

Compliance Considerations Without Overstatement
CMS does not identify site-of-service selection as a standalone audit trigger. However, CMS’s payment methodologies and payer extrapolation of those methodologies mean that inconsistent alignment between care setting, authorization, and billing increases exposure to payment review and post-payment adjustment.

The risk is not inherent to any particular setting, but to misalignment between:

• Intended site of service
• Documented site of service
• Billed site of service

Maintaining consistency across these elements reduces friction under CMS-aligned payment frameworks.

Takeaways:
CMS’s CY 2026 payment policies reinforce a clear principle: the outpatient care setting matters to how services are paid. Through expansion of site-neutral payment approaches, outpatient migration of musculoskeletal procedures, ASC eligibility revisions, continuation of non-opioid pain relief payment policies, and updates to practice expense methodology, CMS continues to align reimbursement with care setting.

For pain management and orthopedic practices, this requires intentional site-of-service planning across clinical, administrative, and billing workflows. Aligning these elements supports reimbursement accuracy and reduces operational disruption under current CMS policy.
