2027 Medicare Payment Cut: What Practices Must Do Before January

How Much Will Medicare Pay Cut in 2027?

As of August 2026, the CMS CY 2027 Physician Fee Schedule proposed rule (CMS-1848-P) would reduce the Medicare conversion factor by up to 1.68% for non-APM physicians and 1.19% for APM participants, effective January 1, 2027. The reduction is driven primarily by the expiration of a temporary 2.5% payment increase Congress provided for CY 2026 only. The Patients First Act (H.R. 9693), a bipartisan bill introduced in July 2026, would reverse the cut by tying future physician payment updates to inflation through the Medicare Economic Index.

• Proposed conversion factors: The non-APM rate would drop from $33.40 to $32.84, and the APM rate from $33.57 to $33.17, according to the CMS proposed rule published July 14, 2026.
• Comment deadline: The 60-day public comment period closes September 14, 2026. The final rule is expected by November 2026.
• Legislative backstop: The Patients First Act would establish permanent, annual inflation-based updates and reform budget neutrality rules that trigger across-the-board cuts.

What Changed in the CMS 2027 Proposed Rule

On July 14, 2026, CMS published the CY 2027 Medicare Physician Fee Schedule proposed rule (CMS-1848-P), a nearly 1,600-page document that proposes sweeping changes to physician reimbursement, coding requirements, and billing compliance. The headline number is the conversion factor cut, but the rule reaches far beyond a single rate adjustment.

The core issue is structural. In 2026, Congress provided a temporary 2.5% payment increase through the One Big Beautiful Bill Act. That increase expires on December 31, 2026. When it lapses, the statutory baseline reverts, and the CY 2027 conversion factor reflects that reversion plus a modest budget neutrality adjustment of approximately 0.53%. The result is a net payment decline for nearly every physician who bills Medicare Part B.

The proposed rule also includes a 50% payment reduction on same-day E/M visits billed with procedures carrying global periods, a transition of the G2211 visit complexity add-on code to a percentage-based modifier, restrictions on third-party remote patient monitoring vendors, and a Request for Information on how AI is transforming clinical workflows. Each of these provisions affects billing operations differently. The modifier 25 payment reduction alone could cost procedural specialties tens of thousands of dollars per provider annually. For a detailed breakdown of that specific provision, see our analysis of the proposed modifier 25 payment reduction.

The most common issue we see providers run into during proposed rule seasons is treating the entire package as a single change. Each provision has a different revenue impact, a different mitigation path, and a different likelihood of surviving the comment period. The conversion factor cut is virtually certain because it is driven by statute, not discretion. The modifier 25 reduction is discretionary and could be narrowed or withdrawn.

Who Gets Hit Hardest by the 2027 Conversion Factor Cut?

The conversion factor reduction applies to every physician, nurse practitioner, physician assistant, and other qualified healthcare professional who bills Medicare Part B. But the practical impact varies by specialty, payer mix, and practice structure.

Independent and small group practices that depend on Medicare for a significant share of patient volume absorb the most pressure. According to the American Medical Association, when adjusted for inflation in practice costs, Medicare physician payment has fallen approximately 33% since 2001. The 2027 cut continues a pattern that has persisted for over two decades. Total operating cost per full-time-equivalent physician rose more than 63% from 2013 to 2022, according to MGMA, while the Medicare conversion factor increased only 1.7% over the same period.

Primary care, family medicine, and internal medicine practices face particular pressure because Medicare represents a larger share of their payer mix than it does for many surgical specialties. Practices in rural areas face a compounding challenge: lower patient volume, higher overhead per encounter, and fewer commercial payers to offset Medicare shortfalls. CMS estimated the overall impact at negative 2% for urology, with similar or larger declines projected for dermatology, podiatry, and ophthalmology when the modifier 25 reduction is factored in.

Providers often come to us after a fee schedule change reduces their per-encounter revenue below the threshold where in-house billing remains cost-effective. When collections per claim drop, the economics of outsourcing shift, because a billing company with higher clean claim rates can recover more per encounter than an overburdened front-office team.

The Patients First Act and Medicare Reform

On July 15, 2026, bipartisan physician representatives in the House introduced the Patients First Act (H.R. 9693), a comprehensive proposal to reform MACRA and the Medicare physician payment system. By early August the bill had 30 cosponsors. The AMA, which endorsed the bill, described it as aligning with the framework endorsed by more than 120 state medical associations and national specialty societies.

The bill proposes four structural reforms. First, it would establish a permanent, annual payment update linked to the Medicare Economic Index minus 1 percentage point, with a floor guaranteeing the update cannot fall below 25% of MEI. Under current law, the cumulative update for most physicians from 2026 to 2036 would be essentially flat at 0.03%. Under the Patients First Act, it would grow by 7.7%.

Second, the bill would raise the budget neutrality threshold from $20 million to $57.64 million in 2028, with regular indexing thereafter. Budget neutrality is the mechanism that forces CMS to cut payment for some services whenever it increases payment for others, even when the increase reflects genuine cost growth. Raising the threshold would reduce the frequency of these across-the-board offsets.

Third, it would replace the Merit-based Incentive Payment System (MIPS) with a new quality measurement framework called POINTS over a five-year transition. MIPS has imposed steep penalties that fall hardest on small, rural, and independent practices without demonstrated improvements in quality of care, according to the AMA. Fourth, the bill would improve alternative payment model participation by freezing the qualifying threshold at 50% for three years.

This legislation is not yet law, and its timeline is uncertain. But it signals bipartisan recognition that the current payment system is unsustainable. For practice managers planning 2027 budgets, the prudent path is to prepare for the proposed cut while monitoring the legislative process.

What Does a Lower Conversion Factor Mean for Your Revenue?

The conversion factor is the dollar multiplier applied to every relative value unit (RVU) on the Medicare fee schedule. When it drops, the allowed amount for every Medicare service drops with it. A 1.68% reduction sounds modest in isolation, but it compounds against years of flat or negative updates.

The table below shows the estimated per-service impact for common E/M codes based on the proposed CY 2027 non-APM conversion factor of $32.84, compared to the current CY 2026 rate of $33.40.

These per-visit losses appear small in isolation. But a family medicine practice seeing 25 Medicare patients per day across 250 working days loses between $12,500 and $25,000 annually on the conversion factor reduction alone, before accounting for the modifier 25 cut or other provisions. For a multi-provider group, multiply accordingly.

In our experience matching providers with billing partners, the practices that weather payment reductions best are the ones that have already eliminated preventable revenue leaks: unbilled charges, under-coded E/M levels, missed modifier opportunities, and denial rework delays. A billing partner running clean claim rates above 95% can offset a 1.68% conversion factor cut simply by collecting what the practice was already leaving on the table.

Steps to Protect Your Revenue Before January 2027

Practices should take seven steps between now and the end of 2026 to minimize the revenue impact of the proposed payment reductions.

1. Model the conversion factor impact against your Medicare volume. Pull your top 20 billed CPT codes, apply the proposed 2027 conversion factor of $32.84 (non-APM) or $33.17 (APM), and compare against your 2026 allowed amounts. This gives you a defensible annual revenue projection.
2. Run a denial rate audit on the last 90 days of Medicare claims. Across the billing companies we vet, a recurring pattern is practices losing 3% to 8% of Medicare revenue to preventable denials. Fixing those gaps before the conversion factor drops partially offsets the cut.
3. Review your E/M coding distribution. Practices that under-code E/M visits by one level leave an average of $30 to $60 per encounter on the table. A coding accuracy review often recovers more than the conversion factor reduction costs.
4. Submit a public comment to CMS before September 14, 2026. Comments go to regulations.gov under docket CMS-1848-P. Include your practice’s specialty, provider count, Medicare patient volume, and the dollar impact of the proposed changes. Individual practice comments carry weight because they provide CMS with real-world data points.
5. Evaluate your billing partner’s regulatory preparedness. Ask whether they have modeled the CMS-1848-P impact for your specialty. If they have not flagged the proposed rule for you by now, their regulatory monitoring may not be sufficient for 2027.
6. Review your payer contracts for rate escalators. Some commercial contracts include automatic adjustments tied to the Medicare fee schedule. Identify which contracts move with the conversion factor and renegotiate before January if possible.
7. Assess whether outsourcing or changing billing partners makes sense at the new rate. When per-encounter revenue drops, the break-even point for outsourcing shifts. A billing company operating at 6% to 8% of collections with a 96% clean claim rate can outperform an in-house team running at 90%.

Tim Daniels, Director of Strategic Accounts at Billing Service Quotes, notes that every proposed rule cycle drives a surge in providers reaching out for billing company comparisons. The practices that move early get matched with partners who have capacity and specialty expertise. The ones that wait until January face a tighter market.

Common Billing Mistakes That Amplify Payment Cuts

A conversion factor reduction hits every claim equally, but billing errors compound the damage. Practices that are already losing revenue to preventable mistakes feel the cut more acutely because their baseline collections are already below what they should be.

Under-coding E/M visits is the most common revenue leak we observe across the providers who come to us for billing company matches. A practice that routinely codes a 99214 visit as a 99213 loses $30 to $60 per encounter before the conversion factor reduction even applies. When the conversion factor drops, the under-coded visit generates even less revenue, widening the gap between what the practice earns and what its documentation supports.

Failing to appeal underpaid or denied claims is the second most costly pattern. Medicare Administrative Contractors deny claims at rates that vary by region and by service type, and many practices lack the bandwidth to work denials beyond the first submission. A billing partner with a structured denial management workflow can recover 40% to 60% of initially denied claims. On a Medicare book of business where 6% to 8% of claims are denied, that recovery represents thousands of dollars per quarter.

Missing charge capture is a third area. Practices that do not have a systematic charge reconciliation process lose billable encounters entirely. A missed charge on a 99214 visit at the proposed 2027 rate is $185 that never enters the revenue cycle. Over a year, even a 1% missed charge rate on a moderate-volume practice represents a five-figure loss.

These mistakes are not caused by the CMS proposed rule, but the proposed rule makes them more expensive. The practices that recover the most revenue under tighter reimbursement are the ones that fix their billing operations first, often by partnering with a company that specializes in their CPT code mix. If your current billing approach is producing CO-97 denial codes on bundled claims or CO-45 adjustments on contractual write-offs, those issues will cost you more at a lower conversion factor.

Should You Outsource Billing Under Tighter Reimbursement?

The question is not whether to outsource. The question is whether your current billing operation, in-house or outsourced, is optimized for a lower-margin environment. When the allowed amount per claim drops, every percentage point of clean claim rate, every day of accounts receivable aging, and every dollar of denial recovery matters more.

For practices currently billing in-house with a small team, the math often shifts when the conversion factor drops. The cost of employing a full-time biller, including salary, benefits, software, clearinghouse fees, and training, remains fixed regardless of what Medicare pays per encounter. When revenue per claim declines, the billing cost as a percentage of collections rises. At some point, outsourcing to a company that charges 6% to 8% of collections and delivers a higher clean claim rate becomes the more cost-effective option.

For practices already outsourcing, the question is whether your current partner is the right fit for the 2027 environment. Across the billing companies we vet, a recurring pattern is that general-purpose billing companies struggle with specialty-specific coding nuances. A family medicine billing company may not understand the modifier complexity that an ophthalmology or podiatry practice requires. When reimbursement tightens, coding precision becomes the difference between collecting what you are owed and leaving money on the table.
