2027 Budget Planning for Orthopaedic Practices: The Revenue Cycle Assumptions CFOs Should Pressure-Test Now

An orthopaedic practice budget for 2027 should start from a lower Medicare baseline than 2026, not a flat one. In its CY 2027 Physician Fee Schedule proposed rule, CMS estimated a 7% aggregate payment reduction for orthopaedic surgery (5% in non-facility settings and 8% in facility settings), driven by a lower conversion factor, the expiration of the one-year 2.5% bump Congress enacted for 2026, and practice expense changes. The groups that protect margin in 2027 will be the ones that budget for that cut explicitly and then offset it with revenue cycle gains they control: cleaner coding, fewer denials, faster collections, and lower cost per claim.

This guide walks through the six revenue cycle assumptions every orthopaedic CFO, COO, and physician president should pressure-test before the 2027 budget is locked.

What changes for orthopaedic practices on January 1, 2027

Four policy shifts land at the same time, and each one touches a different line of the budget.

‍The Medicare conversion factor drops. CMS proposed a 2027 conversion factor of $32.8409 for clinicians who are not qualifying APM participants, down 1.68% from $33.4009 in 2026. Qualifying APM participants would see $33.1693, down 1.19%. The decrease happens even with positive statutory updates because the temporary 2.5% increase enacted for 2026 expires at the end of the year.

‍Specialty-level impact is steeper than the conversion factor alone. CMS's own impact table projects orthopaedic surgery at negative 7% overall. The efficiency adjustment CMS began applying to non-time-based services in 2026 keeps pressure on procedural work RVUs, and the proposed practice expense methodology changes hit facility-based surgical work hardest. Comments on the proposed rule closed September 14, 2026, and the final rule is expected in early November. Budget against the proposed numbers now and adjust when the final rule publishes.

‍The CPT code set changes. The AMA's CPT 2027 code set includes 299 new codes, 74 revisions, and 80 deletions, effective January 1, 2027. Ten of the new codes describe AI-related services, bringing that category to 43 codes. Every annual code set update creates a short window where charge masters, EHR order sets, and payer edits fall out of sync, which shows up as January denials.

‍Site of service keeps moving. In the CY 2026 OPPS final rule, CMS began a three-year phase-out of the Inpatient Only list, starting with 285 mostly musculoskeletal procedures in 2026 and eliminating the list entirely by January 1, 2028. The ASC Covered Procedures List expanded by hundreds of codes. For practices with ASC ownership, that is upside. For practices without it, professional fee economics on outpatient cases need a fresh look.

Assumption 1: Your Medicare rate is not flat

The most common budgeting error we see is carrying 2026 Medicare rates forward. A simple model is enough to size the exposure.

Take your trailing twelve months of Medicare fee-for-service professional collections. Multiply by the specialty impact for your mix of facility and non-facility work. A group collecting $40 million a year with 30% of collections from traditional Medicare has $12 million exposed. At the proposed 7% blended reduction, that is roughly $840,000 of revenue that disappears before anyone sees a single patient. (This example is illustrative. Your number depends on your payer mix and how much of your work is facility-based.)

Then check your commercial contracts. Many commercial and Medicare Advantage agreements are pegged to a percentage of the Medicare fee schedule. If your contract pays 125% of current Medicare, a Medicare cut flows straight through to that payer unless the contract locks a specific year's schedule. Pull the reimbursement language on your top five payers before you finalize the budget.

Assumption 2: Your coding accuracy is costing more than you think

When rates fall, the cost of undercoding rises in relative terms. Every E&M visit coded a level too low and every surgical case missing a legitimate add-on code or modifier now represents a larger share of the margin you have left.

Orthopaedic practices are especially exposed in three places:

• E&M level distribution. Surgeons often default to 99213 and 99214 regardless of what the documentation supports under the AMA's medical decision making framework. Decisions for major surgery, prescription drug management, and independent interpretation of imaging are frequently documented but never counted.
• Surgical coding completeness. Multi-procedure cases, bilateral procedures, and staged procedures within the global period depend on correct use of modifiers 50, 51, 58, 59, and 79. One missed modifier can turn a payable second procedure into a bundled denial.
• Diagnosis specificity. ICD-10 laterality, encounter type, and fracture detail drive medical necessity. Unspecified codes invite denials and weaken appeals.

For the budget, set an explicit coding accuracy target rather than assuming last year's performance repeats. Commission a sample audit of 50 to 100 charts per surgeon, compare the coded level to the supported level, and translate the gap into dollars. That number belongs on the revenue line as a recoverable opportunity, not a hope.

Maia's E&M AutoCoder and Surgical AutoCoder are built to close exactly this gap, recommending codes, modifiers, and clinical justification inside the EHR before a human coder touches the chart. Practices using AutoCoder see a 1% to 5% lift in surgical revenue and efficiency gains of 25% to 35% on E&M coding and 50% on surgical coding.

Assumption 3: Your denial rate will not improve by itself

Denials are getting worse across the industry. In Experian Health's State of Claims 2025 survey of 250 healthcare professionals, 41% of providers said more than 10% of their claims are denied, up from 38% in 2024 and 30% in 2022. Fifty-four percent said claim errors are increasing, and 68% said submitting clean claims is harder than it was a year ago.

Orthopaedics carries above-average denial risk because of prior authorization requirements for advanced imaging and surgery, high-dollar implant claims, and the modifier complexity described above. For 2027, budget denial performance in three parts:

1. Initial denial rate by payer. Use your actual trailing rate, not a target. If you do not track it by payer and denial reason (CARC and RARC codes), make that the first revenue cycle project of the year.
2. Overturn rate on appeals. A denial that is appealed and won still costs staff time and delays cash. A denial that is never worked is lost revenue.
3. Cost to rework. Every denied claim consumes biller and coder time. Multiply your annual denial volume by the average minutes to resolve and your fully loaded hourly staff cost. Most practices are surprised by the result.

Then set a reduction target for the categories you can prevent upstream: authorization, coding, and eligibility denials. Those are the ones with budget leverage.

Assumption 4: Your staffing costs keep rising

Coder and biller wages have climbed steadily, and turnover in revenue cycle roles remains high. Every departure resets productivity while a replacement is recruited and trained, and backlogs during that gap push AR days up.

When you build the 2027 staffing line, model three things:

• Charts per coder per day for E&M and surgical work separately. Surgical charts take far longer, and that capacity is the usual bottleneck.
• Days to bill (charge lag). A coding backlog is a cash flow problem. If charts sit for five or more days before claims go out, that delay compounds across every payer.
• Cost per claim fully loaded, including outsourced coding vendors if you use them.

The strategic question for 2027 is whether you can absorb volume growth or a new surgeon without adding headcount. Practices that automate first-pass coding shift their coders toward review, exception handling, and audit work, which is a better use of experienced staff and a more stable cost structure.

Assumption 5: Your prior authorization workload is growing

Prior authorization remains one of the biggest administrative drains in orthopaedics. Advanced imaging, injections, DME, and nearly all elective surgery require it from at least some payers. CMS's interoperability and prior authorization final rule requires impacted payers to meet new decision timeframes beginning in 2026 and to support electronic prior authorization APIs by January 1, 2027, but practices should not budget for an immediate drop in workload. The volume of requests is not shrinking.

Budget the full cost of prior authorization: staff hours, delayed or cancelled cases, and denials for missing or mismatched authorizations. Then decide which parts of that workflow you will automate or reconcile systematically in 2027.

Assumption 6: Your site of service mix is shifting

As joint replacement and spine procedures continue to move to ASCs and hospital outpatient departments, professional fee economics change with them. Facility-setting professional payments carry the steepest proposed reduction for 2027, and the IPO phase-out accelerates migration of cases out of the inpatient setting.

If your group has or is considering ASC ownership, model facility fee revenue separately from professional fees and pressure-test case volume assumptions by procedure. If your group is part of or evaluating a PE-backed platform, expect the platform to scrutinize revenue per surgeon and revenue cycle cost per surgeon closely. Both metrics improve with cleaner coding and lower rework.

How to build a revenue cycle scenario into the 2027 budget

A good 2027 budget has three scenarios, and the revenue cycle assumptions should move with each one.

Downside. The final rule matches or exceeds the proposed 7% orthopaedic reduction, commercial contracts pegged to Medicare follow it, and denial rates hold at 2026 levels.

‍Base. The final rule softens slightly, your top commercial contracts hold flat, and you recover a modest share of identified undercoding and denial leakage.

‍Upside. You close most of the coding accuracy gap identified in your audit, cut preventable denials meaningfully, and reduce charge lag to one or two days.

The gap between downside and upside is usually larger than the Medicare cut itself. That is the point leadership teams need to see: the fee schedule is outside your control, but coding accuracy, denial prevention, and speed to bill are not.

Orthopaedic groups use Maia to automate coding and revenue cycle work across Athena, eClinicalWorks, and coming soon, Epic, ModMed, NextGen, and Tebra. For budgeting, the value is predictability: coding throughput that scales with volume, and denial prevention that happens before the claim goes out.

A 2027 budget checklist for orthopaedic leaders

Before you lock the budget, make sure your team has done the following:

1. Modeled Medicare professional revenue at the proposed 2027 rates, with a placeholder to update after the final rule.
2. Identified every commercial and Medicare Advantage contract pegged to the current Medicare fee schedule.
3. Run a sample coding audit and quantified undercoding by surgeon and by service line.
4. Pulled denial rates by payer and by denial reason for the trailing twelve months.
5. Calculated fully loaded cost per claim and charts coded per coder per day.
6. Mapped CPT 2027 changes against your charge master and EHR order sets.
7. Measured current charge lag and set a target.
8. Built downside, base, and upside scenarios with revenue cycle assumptions that move independently of fee schedule assumptions.

Frequently asked questions

How much will Medicare cut orthopaedic surgery payments in 2027?

CMS's CY 2027 Physician Fee Schedule proposed rule projects a 7% aggregate reduction for orthopaedic surgery, with an 8% reduction in facility settings and 5% in non-facility settings. The proposed conversion factor for non-APM clinicians is $32.8409, down 1.68% from 2026. The final rule is expected in early November 2026 and may change these figures.

When does the 2027 CPT code set take effect?

The AMA's CPT 2027 code set takes effect January 1, 2027. It includes 299 new codes, 74 revised codes, and 80 deleted codes. Practices should update charge masters, EHR order sets, and coding references before January claims go out.

What revenue cycle metrics should an orthopaedic practice include in its budget?

At minimum, budget initial denial rate by payer, appeal overturn rate, days in AR, charge lag (days to bill), cost per claim, coder productivity, and net collection rate. MGMA's DataDive benchmarks are a useful external reference for comparing your performance with peer orthopaedic groups.

Can better coding offset a Medicare fee schedule cut?

In many practices, yes, at least partially. Undercoded E&M visits, missed surgical modifiers, and preventable denials often represent several percentage points of collectable revenue. Closing that gap does not change the fee schedule, but it can offset a meaningful share of the 2027 reduction while also lowering the cost to collect.

Should we budget for AI coding in 2027?

If your practice is adding surgeons, struggling with coder turnover, or seeing charge lag above two or three days, AI coding deserves a line in the 2027 budget. Experian's 2025 survey found only 14% of providers use AI to reduce denials, but 69% of those that do reported fewer denials or better resubmission success. Evaluate vendors on orthopaedic specificity, EHR integration, and audit transparency.

When should orthopaedic practices finalize their 2027 budget?

Most groups finalize in November or December. Build the model now using the proposed rule, then update Medicare assumptions within a week of the final rule's publication.

The bottom line

The 2027 fee schedule will take money out of every orthopaedic practice that bills Medicare. The practices that come out ahead will be the ones that treat coding accuracy, denial prevention, and speed to bill as budget line items with targets and owners, not as back-office functions that take care of themselves.
