2027 Medicare Physician Fee Schedule: Dermatology Down 9%

TL;DR: The 2027 Medicare Physician Fee Schedule proposal pays only the most expensive same-day service in full and cuts every other same-day procedure or E/M visit to 50 percent, driving an estimated 9 percent dermatology payment cut. Comments close September 14. The defensible response is charge capture, documentation, and denial prevention, starting now.

The visit-plus-biopsy encounter that fills a dermatology schedule is the exact line item CMS just proposed to cut. Under the 2027 Medicare Physician Fee Schedule proposed rule, when a dermatologist performs an E/M visit and a procedure on the same day, CMS would pay the more expensive service at 100 percent and cut everything else that day to 50 percent. HFMA scores the net effect at a 9 percent payment cut for dermatology. If your dermatology billing already runs on thin margins and a 14 percent denial rate, this proposal lands on the exact visits that keep the practice solvent.

What the 2027 proposal changes

The proposed rule, issued July 14, 2026, moves three numbers dermatology administrators should know before they model next year's revenue.

The conversion factor drops for everyone. CMS proposes $33.17 for qualifying APM participants, down 1.19 percent, and $32.84 for everyone else, down 1.68 percent. The statutory updates are positive on paper, 0.75 percent for qualifying participants and 0.25 percent for the rest, but the 2.5 percent temporary increase Congress funded for 2026 expires at the same time, and its expiration swamps the gains. The math takes the familiar Medicare shape, a small raise on the surface with a larger expiration underneath it.

The bigger story sits in the same-day payment provision. In CMS's own words, "The most expensive service (either surgical or E/M visit) would be paid at 100% and all other surgical procedure(s) or E/M visit(s) furnished on the same day would be paid at 50%." That single sentence rewrites the economics of the most common visit type in dermatology.

Source figures come from the CMS fact sheet on the CY 2027 proposed rule.

Why the same-day rule hits dermatology harder than the conversion factor does

The conversion factor cut is under 2 percent. The specialty impact estimate for dermatology is 9 percent. The gap between those two numbers is the same-day provision, and understanding why explains what to do about it.

Dermatology runs on combined visits. A patient comes in for an evaluation, the dermatologist finds a suspicious lesion, and the biopsy or destruction happens in the same encounter. Under current rules, when documentation supports a significant, separately identifiable E/M service, modifier 25 lets the practice bill both the visit and the procedure at full value. The payment system treats them as two services because clinically they are two services.

The proposal changes the arithmetic without asking about the documentation. Whichever service carries the lower price that day takes a 50 percent cut, regardless of how well the chart supports both. A practice whose schedule is built around same-day evaluation and treatment loses on nearly every encounter, which is why HFMA's analysis lands dermatology and otolaryngology at minus 9 percent while specialties that rarely combine a procedure with a visit come out ahead. The revenue defense that used to live in modifier 25 documentation shifts somewhere else: to charge capture accuracy, to sequencing decisions, and to keeping the denial rate on the remaining full-price services as low as it will go.

Who wins and who loses under the proposal

HFMA's specialty-level estimates put names on the damage. Their analysis of the 2027 Medicare Physician Fee Schedule estimates the combined effect of the conversion factor, efficiency adjustments, and the same-day provision by specialty.

The pattern is not subtle. Procedural specialties that combine visits and procedures absorb the cut. Visit-only specialties gain. ENT practices sit in the same position as dermatology, and if you run ENT billing and credentialing, the same math applies to your endoscopy-plus-visit encounters.

The number that decides whether you absorb this or bleed from it

Dermatology denial rates already run around 14 percent, nearly triple the 5 percent industry average.

That standalone fact is why the 2027 Medicare Physician Fee Schedule matters more for dermatology than a 9 percent estimate suggests. A cut this size on top of an already elevated denial rate compounds. Every denied claim in 2027 will be a denied claim at the reduced rate, and every write-off you tolerate today gets 9 percent harder to justify. Practices that treat denial prevention as back-office housekeeping will feel the full 9 percent. Practices that treat it as revenue defense will feel meaningfully less.

What a dermatology practice should do between now and January 2027

None of this requires waiting for the final rule. The moves below pay off whether or not the same-day provision survives in its proposed form.

• File a comment before September 14. CMS reads specialty-specific operational detail, and a comment describing real same-day encounter economics carries more weight than a form letter.
• Model your same-day exposure now. Pull twelve months of encounters where an E/M and a procedure share a date of service, price the lower-value service at 50 percent, and you have your practice-specific version of the 9 percent estimate. Your number may land well above or below the specialty average, which is exactly why the model is worth running.
• Tighten charge capture to daily. Under a lower fee schedule, a missed charge is pure loss. Weekly charge review leaves too many encounters unbilled at rates you can no longer afford to waste.
• Audit your documentation before the payer does. When every same-day encounter pays less, a denial on top of the reduction is the worst outcome on the schedule. Documentation that clearly supports medical necessity keeps the remaining revenue collectable.
• Work the denial categories you already recognize. Modifier-related denials and medical necessity denials dominate dermatology, and both are preventable with the right front-end review.

The comment costs an hour and the exposure model costs an afternoon, and both are cheaper than learning your practice-specific number from January's remittances.

How HRG handles a fee schedule cut like this one

Halfway through a proposal like this, most billing vendors will promise to make it painless. We have been doing this for over 26 years, and the honest version is different: nobody restores a federal payment cut. What a billing partner controls is everything the cut makes more expensive, meaning denials, slow follow-up, missed charges, and A/R that ages while nobody watches it.

That is where the model matters. HRG works directly inside your EHR, PM system, and payer portals, so charge capture and claim status live where your staff already looks, with no separate dashboard and no PDF report lag. Our billers, all 100 percent U.S.-based, run weekly and monthly A/R reviews themselves, so an emerging denial pattern gets caught in days. HRG targets a 98 percent first-pass claim acceptance rate, a track record confirmed by our CFO, and responds to denials within 24 to 48 hours. Clients typically see denial reductions of 15 to 30 percent, which at 2027 rates is not tidiness, it is the margin.

One scope note, because it matters for this topic: HRG provides coding consultation as needed. Your coders or coding vendor perform the coding itself, and HRG does not perform or audit coding. What we bring to a fee schedule change is the billing-side machinery, meaning clean claims, denial prevention and appeals, and A/R follow-up by the people doing the work. For the deeper denial playbook, our guide to denial management in medical billing covers the categories that recur in procedural specialties, and the dermatology billing complete guide covers the specialty's baseline mechanics.

Where a billing partner fits when rates drop

The middle column is where procedural specialties get hurt in a repricing year. A vendor that discovers the 2027 changes through its denial queue has made your practice the canary.

What this looks like if the final rule softens

CMS proposals rarely survive comment periods untouched, and the same-day provision is the piece procedural specialties have the most reason to contest. The final rule typically lands in November. If the 50 percent provision is withdrawn or phased, the conversion factor cut still lands, and everything above still applies at smaller scale. Should it survive, the practices that modeled their exposure in September will be the ones that renegotiated schedules, tightened documentation, and entered January with their denial rate already falling. Preparation is cheap. Surprise is not.

2027 Medicare Physician Fee Schedule: what dermatology practices are asking

Is the 50 percent same-day payment cut final?

No. It is a proposal, and CMS can withdraw, phase, or soften it in the final rule expected in November 2026. HRG advises clients to model it as written anyway, because a practice that prepared for a provision that never lands has lost an afternoon, and the reverse costs far more.

When do comments close on the 2027 Medicare Physician Fee Schedule?

September 14, 2026. CMS issued the proposed rule on July 14, 2026, and the final rule typically arrives in November. HRG encourages dermatology and ENT clients to submit operational comments, because specialty-specific encounter data is what CMS weighs most.

Does the same-day reduction apply when the visit and procedure happen on different days?

No. The proposal keys on the date of service, so services furnished on separate days each price normally. Splitting visits carries its own costs in patient access, no-shows, and scheduling load, which is why HRG models the exposure before any practice redesigns its schedule around a proposal that may not survive.

Does the 9 percent dermatology estimate include the conversion factor cut?

Yes. HFMA's specialty estimates combine the conversion factor, the efficiency adjustment, and the same-day payment provision. HRG treats the 9 percent as a specialty average, not a practice-level prediction, which is why modeling your own same-day encounter mix matters.

Can better documentation avoid the same-day reduction?

No. Unlike a modifier 25 denial, the proposed reduction applies by policy, not by documentation quality. What documentation still controls is whether the remaining revenue survives payer review, which is where HRG focuses denial prevention when rates drop.

Does HRG handle the coding changes the 2027 rule brings?

HRG provides coding consultation as needed, and your coders or coding vendor perform the coding itself. What HRG runs is the billing side: clean claim submission inside your EHR, denial prevention and appeals, and A/R follow-up with weekly reviews by the billers doing the work.

The September question

Dermatology has absorbed payer pressure before, but rarely with a deadline this specific. The comment window closes September 14, and the modeling is worth doing whether or not you write a word to CMS. If stuck claims are already part of the problem, start with the hidden revenue issues in dermatology billing and count what the current denial rate costs before the cut makes it worse.
