2027 MPFS Proposed Rule: Why the Real Story Isn’t the Conversion Factor

Episode Date: September 23, 2026

In this episode of Stark Integrity, host Bob Wade ("Captain Integrity") examined the proposed 2027 Medicare Physician Fee Schedule (MPFS) and offered a perspective that differs from many traditional healthcare industry summaries. While much of the discussion surrounding the proposed rule has focused on conversion factor reductions and reimbursement changes, the more significant story may be CMS's effort to reshape how physician services are valued and how future physician compensation models may evolve.

Most annual MPFS analyses begin and end with one question: What happened to the conversion factor? Although reimbursement changes undoubtedly affect provider economics, the proposed 2027 rule contains broader policy signals that could have long-term implications for physician compensation, fair market value (FMV), commercial reasonableness analyses, and Stark Law compliance.

Looking Beyond Annual Payment Adjustments

The proposed rule suggests CMS is increasingly focused on reexamining the underlying methodology used to value physician services. Rather than simply adjusting reimbursement levels from year to year, CMS appears to be questioning some of the foundational assumptions that have influenced physician payment systems for decades.

For healthcare organizations, compensation committees, valuation professionals, and compliance officers, this broader direction may ultimately prove more significant than any individual reimbursement adjustment.

The G2211 Proposal Raises New FMV Questions

One notable proposal involves CMS replacing HCPCS code G2211 as a separate add-on payment with a modifier-based methodology attached to office and outpatient evaluation and management services. CMS projects meaningful payment increases for qualifying practitioners as well as enhanced benefits for certain Accountable Care Organization participants.

The reimbursement increase itself is not the most interesting aspect of the proposal. The more significant question involves physician compensation.

If reimbursement increases occur without corresponding increases in physician effort, productivity, or work hours, healthcare organizations may be forced to address whether physician compensation should increase proportionally. For physician compensation models based on collections, changes in reimbursement methodology may produce significant increases in physician income without any corresponding change in physician work effort.

This creates a distinction between higher reimbursement and higher fair market value, a distinction that compensation committees may be required to evaluate more closely going forward.

Practice Expense Reform May Have Long-Term Significance

Perhaps the most underreported aspect of the proposed rule involves CMS's proposed practice expense reforms.

CMS proposes reducing reliance on specialty survey data and moving toward methodologies driven more directly by cost information and transparency. The proposal also includes changes to indirect practice expense allocation methodologies and a phaseout of the Indirect Practice Cost Index.

Although these proposals appear highly technical, they may have profound implications. For decades, physician compensation valuation and benchmarking analyses have operated within reimbursement systems heavily influenced by specialty survey methodologies. CMS now appears willing to reevaluate components of that framework.

For valuation professionals, this may represent an early indication that certain long-standing assumptions should not be viewed as permanent.

Compliance Through Reimbursement Policy

The proposed rule also contains significant revisions related to Remote Patient Monitoring (RPM) and Remote Therapeutic Monitoring (RTM).

CMS proposes new requirements involving established patients, initiating visits, and limitations on the use of contractors for certain monitoring services. Importantly, CMS explicitly links portions of these proposals to concerns expressed by the Office of Inspector General regarding fraud, waste, and abuse.

What makes this development noteworthy is the mechanism being used. Rather than creating new Stark Law exceptions or Anti-Kickback Statute safe harbors, CMS appears to be using reimbursement policy itself as a compliance tool. In effect, CMS is attempting to reduce compliance risk before claims are submitted rather than relying solely on traditional enforcement mechanisms after the fact.

Final Thoughts

The lasting impact of the proposed 2027 MPFS rule may not be the conversion factor reductions discussed in most healthcare publications. Instead, the more significant development may be CMS's willingness to reconsider how physician services are valued, how complexity is recognized, how care management services are delivered, and how reimbursement methodologies should evolve in the future.

These developments extend beyond reimbursement. They have the potential to influence physician compensation models, FMV analyses, commercial reasonableness evaluations, compensation committee governance, healthcare transactions, and Stark Law compliance for years to come.

Ultimately, the proposed rule may be remembered less for what physicians were paid and more for how CMS began redefining why physicians are paid. That distinction may prove to be the most important aspect of the entire proposal.
