2027 Medicare Reimbursement Changes: How Specialty Clinics Can Prepare Their Budgets
Building a 2027 budget means setting Medicare reimbursement assumptions before the 2027 Medicare Physician Fee Schedule is final. CMS issued the proposed rule in July, and the final rule is expected around November 1, which for many organizations lands after the plan has gone to a board.
On October 27 we ran a 30-minute session on what that means for specialty clinic finance teams. Courtney Mashhoon covered the proposed changes with the most direct effect on a clinic P&L, and Gianna Montini demonstrated how to model them in Workday Adaptive Planning. The full recording is above.
Why the 2027 Medicare rule complicates budgeting
The rulemaking calendar and the budgeting calendar do not line up. CMS issued the proposed rule on July 14, comments closed September 14, the final rule is expected around November 1, and the provisions take effect on or after January 1, 2027.
That sequence creates a familiar problem. Reimbursement assumptions have to be set while the numbers are still proposed, and the confirmed figures arrive late in the cycle or after approval. It repeats every year, which is why it is worth solving structurally. As Courtney noted during the session, a model set up now to absorb a swing in the percentages pays forward into every cycle that follows.
The proposed changes that matter most
Two conversion factors, both lower. CMS proposes $33.1693 for qualifying Advanced APM participants and $32.8409 for everyone else, decreases of 1.19% and 1.68% from CY 2026, driven largely by the expiry of the one-year 2.50% statutory increase that applied in 2026. A lower conversion factor is not an equivalent reduction in total Medicare revenue, since RVU changes, budget neutrality adjustments and your own service mix all move the final figure. It does mean knowing which rate applies to you, since qualifying Advanced APM status is a separate determination from MIPS participation.
The practice expense overhaul. This is the proposal Courtney asked the audience to watch most closely. CMS would phase out the Indirect Practice Cost Index over a two-year transition beginning in 2027, the first step in a multiyear change to practice expense methodology that moves away from specialty survey data dating in some cases to 2007 or earlier. A proposed stabilizer would cap annual increases and decreases in practice expense RVUs at roughly 5% for most existing services. The cap applies to practice expense RVUs rather than total payment, and because it limits movement every year rather than only the first, the full effect can extend beyond 2028. For an office-based clinic this part of the formula carries rent, equipment and support staff, so a single-year budget will not show where it settles.
Same-day evaluation and management services. When a separately identifiable office or outpatient E/M visit is furnished by the same physician or group practice on the same day as a procedure carrying a 0, 10 or 90-day global period, the most expensive service, whether that is the procedure or the visit, would be paid at 100%, and any other surgical procedure or E/M visit furnished that day would be paid at 50%. The implication sits in revenue per visit rather than revenue per code, so volume growth stops converting at the historical ratio. Procedural specialties carry the most exposure.
Remote monitoring and quality reporting. CMS proposes that both remote physiological and remote therapeutic monitoring require a separately reportable initiating visit and be payable only when clinical staff employed by the practice furnish the service, excluding third-party contractors. RTM would additionally be limited to established patients. For a clinic running either program through a vendor, that is a program-level revenue question with a contracting lead time longer than a budget cycle. CMS also proposes to sunset traditional MIPS reporting in 2029 in favor of MIPS Value Pathways.
Why one Medicare assumption may not be enough
Budget neutrality explains why these proposals do not move every practice the same way. Since 1992, if CMS projects that its pricing changes would shift total fee schedule spending by more than $20 million, it has to offset the difference, usually through the conversion factor, and the AMA notes that threshold has never been updated for inflation. An increase in one part of the schedule is therefore funded from the rest of it, and this cycle money moves toward evaluation and management and behavioral health and away from procedural work.
The published estimates show the range. HFMA's impact brief on the proposed rule puts dermatology and otolaryngology down roughly 9% and orthopedic surgery down about 7%, with clinical psychology up about 11% and clinical social work up about 12%.
Read those figures carefully. They reflect the proposed changes to relative value units, measured before the separate conversion factor effect, and they are directional estimates rather than final reimbursement outcomes. What any individual practice experiences will depend on its own service mix and the conversion factor that applies to it.
Applied across a mixed organization, a blended Medicare rate nets those movements against each other, so the consolidated total can look reasonable while individual service lines move in opposite directions. Commercial exposure can widen the gap, since many contracts are priced against the Medicare fee schedule, though terms vary and some are fixed to a specific year.
How we modeled the impact in Workday Adaptive Planning
Gianna built the demonstration around the question a blended assumption cannot answer: what is happening underneath the total?
The model carried two versions of the same plan. One applied a single blended Medicare rate change pushed down to every level. The other carried a separate assumption for each specialty. Both ran on the same patient volumes and the same underlying assumptions, so the only variable was the granularity of the rate.
Switching between them took one input. An assumption sheet held a single field, a 1 for the blended method and a 2 to plan by specialty, and every formula downstream read that field. Underneath sat net patient revenue by level and specialty, Medicare percent of revenue, the calculated Medicare rate change, the revenue and rate impact, and the effective rate change over time. Medicare revenue was calculated as net patient revenue multiplied by the Medicare percent of revenue, so a change to a specialty assumption flowed through month over month without anyone editing a formula.
The sample dataset used for the session showed how much that choice can matter. Planning at a blended rate applied a 2.4% Medicare rate reduction uniformly across every specialty. Planning at the specialty level, against the same volumes and the same underlying assumptions, produced a positive effective rate change of 2.97%.
Those are demonstration figures from a sample organization whose mix happened to be weighted toward specialties projected to gain. They are not a forecast for any real clinic, and they do not say that specialty-level modeling always produces a better number. What drove the difference was the methodology and the service mix underneath it.
Gianna entered specialty-level percentages directly on the sheet, copied them forward and saved, then opened a comparison report placing the two versions side by side. The impact carried through to a sample P&L showing prior year actuals, total revenue under each method, Medicare net patient revenue, the rate impact and non-Medicare revenue, by level and by specialty.
The value sits in the connections rather than any single screen. Assumptions live in one place, two methodologies can be compared without maintaining two models, and service-line results roll up through the same structure that produces the consolidated statements, so the forecast and the reporting update together.
As Gianna summarized it, finance can run a blended view for a quick top-down plan and switch to specialty-level detail when accuracy matters. Granularity is not automatically more accurate, since the specialty assumptions still have to be right. What it gives you is visibility into which parts of the organization are driving the result.
Three steps to prepare your 2027 forecast
Confirm which conversion factor applies to you. Qualifying Advanced APM participant status sets your base rate and is a separate question from MIPS participation. Better resolved now than during budget revisions in December.
Decide whether Medicare belongs at the service-line level in your model. If your organization spans specialties the published estimates move in different directions, a blended assumption will net them against each other. Dimensioning revenue by service line, and by payer where your contracts warrant it, makes the difference visible.
Set the model up so a new assumption flows through on its own. The aim is for the final rule to be an input change rather than a modeling project, with the forecast and the reporting updating from the same source.
Closing thought
The useful question is not how large the 2027 cut will be. It is whether your team can see what a change in reimbursement assumptions does across specialties, payer mix, revenue and margin without rebuilding the forecast to find out. Whether these proposals are finalized as written, modified, or set aside, reimbursement assumptions will keep changing in future planning cycles, and the ability to evaluate those changes quickly holds its value well beyond any single rule.
