CMS has proposed significant changes to physician reimbursement, coding requirements, and billing compliance. Here’s what you need to know, and what we recommend your organization prioritize before it’s finalized.
On July 14, 2026, CMS released its proposed rule for the Calendar Year (CY) 2027 Medicare Physician Fee Schedule. The nearly 1,600-page document outlines sweeping changes to physician reimbursement, coding requirements, and billing compliance across virtually every specialty.
While the rule remains in proposed form until the public comment period closes on September 14, 2026, the direction is clear: payment margins are shrinking, billing rules are becoming more complex, and the cost of a compliance error has never been higher. Practices that start preparing now will be in a fundamentally different position than those that wait until January.
Here are MDaudit’s key takeaways from the proposed rule, and what we recommend your organization prioritize before it’s finalized.
Takeaway #1: Payment Cuts Are Coming, and They’re Broader Than You Think
The most immediate impact of the proposed rule is a decline in Medicare payments to physicians. The proposed conversion factors are $33.17 for qualifying Alternative Payment Model (APM) participants, down 1.19% from 2026, and $32.84 for non-APM participants, down 1.68% from 2026.
The driver is straightforward: the temporary 2.5% payment increase that was in place for 2026 is expiring, and positive adjustments elsewhere are not enough to offset the loss. While the percentage decrease may look modest in isolation, it compounds quickly across thousands of annual claims.
The specialty-level impact is more pronounced. Dermatology faces a proposed 9% decrease, orthopedic surgery 7%, and hand surgery 5%. A few specialties see increases, with clinical social work at +12% and clinical psychology at +11%, but the majority of practices will see smaller reimbursement checks at a time when operational costs are not declining to match.
For specialties already operating on thin margins, the 2027 proposed rule is not a minor adjustment. It’s a signal that protecting revenue through billing accuracy and compliance integrity is no longer optional. It’s a financial imperative.

Takeaway #2: New Billing Rules Will Directly Affect What You Get Paid
Payment rate changes are only part of the story. The proposed rule also introduces structural billing changes that will directly affect reimbursement for specific services. These are not minor coding updates. They are new payment rules that require billing staff to understand, implement, and audit correctly from day one.
The key changes include:
- E/M and global procedure overlap: When a physician performs a surgical procedure with a global period and a separately identifiable E/M visit on the same day, the highest-value service is paid at 100% while other services are paid at 50%. Correctly identifying which E/M visits are truly separate from bundled care will be essential.
- G2211 complexity add-on transition: This code is moving from a flat-rate payment to a 16% modifier, requiring updates to billing systems and documentation workflows.
- New ACO modifier: A 32% add-on for E/M visits by clinicians in MSSP or the LEAD model, available only to those who meet eligibility criteria. Missing this modifier means leaving significant revenue uncaptured, and applying it incorrectly creates compliance exposure.
- Remote monitoring restrictions: Billing for remote patient monitoring now requires established patient status, a prior initiating visit, employed (not contracted) staff, and payment adjustments based on updated device costs. Each criterion must be verifiable at the claim level.
Each of these rules is designed to address legitimate policy concerns. But they also create meaningful operational complexity. A single miscoding error, multiplied across hundreds of encounters, translates directly to revenue loss or compliance risk.
For practices navigating multiple billing rule changes at once, where a single miscoded modifier across hundreds of encounters means real revenue loss, getting ahead of claims before they’re submitted is critical. See how MDaudit’s eValuator analyzes 100% of encounters pre-bill, flagging documentation gaps and coding issues before they become denials.
Takeaway #3: The Cost of a Compliance Gap Is Higher Than It’s Ever Been
Tighter margins and more complex billing rules create a compounding risk: the financial impact of a coding error is greater precisely when practices can least afford it.
Consider what the stakes look like in practical terms. Miscoding the G2211 complexity modifier across hundreds of visits means forfeiting the 16% add-on on every one of them. Billing remote monitoring to non-established patients or without a required initiating visit triggers mass claim denials. Failing to apply the 50% overlap reduction correctly on E/M and global procedure claims creates overpayment liability and potential fraud exposure. Missing the ACO modifier on eligible visits means leaving 32% of entitled reimbursement uncaptured.
Many practices have historically relied on manual chart reviews or periodic random audits to identify these kinds of issues. Those approaches were imperfect even before the 2027 rule changes. With new rules rolling out across multiple billing categories simultaneously, manual processes simply will not scale.
The practices best positioned for 2027 are those that shift from periodic compliance reviews to continuous, pre-bill auditing: catching issues before they become denials, overpayments, or audit findings.

Takeaway #4: AI-Powered Auditing Becomes Your Competitive Advantage
The 2027 rule changes are complex enough individually. Together, they represent a new compliance environment that requires a fundamentally different approach to billing integrity.
MDaudit’s AI-powered coding audit tools with native Epic integration are designed to address these challenges at scale. For the new E/M and global procedure overlap rule, the platform examines clinical documentation to verify that E/M visits are truly separately identifiable, flagging claims where the 50% reduction should apply before they leave the building. For remote monitoring, Auditor Assist checks established patient status, initiating visit completion, employed staff verification, and device cost alignment against the updated requirements, ensuring claims meet the new criteria before they are submitted.
But the broader value is not just catching individual errors. Continuous pre-bill auditing across your entire claim volume means you are not managing compliance reactively. You are preventing revenue leakage proactively, with every claim fully defensible, clinically justified, and documented with source-linked recommendations.
For specialties facing the steepest payment pressure under the 2027 proposed rule, this level of oversight is not a nice-to-have. It’s the difference between capturing what you’ve earned and writing off revenue you were entitled to.

What to Do Before September 14
The public comment period closes on September 14, 2026. That is not much runway, but it is enough time to get ahead of the changes if you move now. Here is where to focus:
- Audit your current billing workflows against each of the four rule changes above. Identify where your documentation and billing systems will need to be updated.
- Train coding and billing staff on the G2211 modifier conversion, ACO eligibility criteria, remote monitoring restrictions, and the E/M overlap rule. These are not edge cases. They will affect claim volume across specialties.
- Update your billing systems to capture the data elements required for the new rules, particularly for ACO modifier eligibility and remote monitoring staff and patient criteria.
- Implement continuous pre-bill auditing so compliance gaps are identified before claims are submitted, not discovered through denial management or a CMS audit.
Practices that move quickly will enter 2027 with confidence. They’ll capture every dollar they’re entitled to, avoid the compliance pitfalls the new rules create, and protect their revenue despite the payment headwinds. The practices that wait will spend the year reacting: working denials, recovering overpayments, and scrambling to retrain staff mid-year.
The comment period is an opportunity to weigh in. But preparation cannot wait for the final rule.
