CY2027 Medicare Physician Fee Schedule: What RCM Teams Need to Model Before January 1

CMS released the CY2027 Medicare Physician Fee Schedule proposed rule (CMS-1848-P) on July 14, 2026. The public comment period closed September 14. A final rule is expected in November, effective January 1, 2027 — which gives revenue cycle and compliance teams a narrow window to model impact before it’s locked in, and an even narrower one to actually operationalize whatever the final version says.

The number everyone will quote: a conversion factor cut that isn’t really a new cut

The proposed rule sets two conversion factors: $32.84 for most physicians (down 1.68% from CY2026) and $33.17 for clinicians in qualifying Alternative Payment Models (down 1.19%). Read in isolation, that looks like CMS decided to pay less. The more accurate read: CY2026 included a one-year 2.5% bump from the Working Families Tax Cut legislation, and that bump simply expires. Strip it out, and this year’s move is a modest net increase — a 0.53% budget-neutrality adjustment plus the statutory MACRA updates (0.75% for QPs, 0.25% for non-QPs) — that still nets negative once the temporary increase disappears. The distinction matters for how you frame this internally: it’s a baseline reset, not evidence CMS is actively squeezing the schedule further.

The change that will actually hit revenue cycle harder: same-day E/M plus a global procedure

Buried well below the conversion factor headline is the change most likely to show up as a denial or an underpayment if nobody catches it in time. When the same physician bills an E/M visit and a 0-, 10-, or 90-day global procedure on the same day, CMS is proposing to pay the most expensive service at 100% and everything else at 50% (an alternative 25% was also floated). Today, both are effectively paid close to full value. That 50-point swing lands hardest on specialties that routinely combine an E/M visit with an in-office procedure — dermatology, orthopedics, OB-GYN, and primary care practices doing minor procedures — and it’s exactly the kind of change that claims-scrubbing logic built around today’s rules won’t catch on its own.

Remote monitoring loses its third-party vendor model

Remote Physiologic Monitoring and Remote Therapeutic Monitoring (RPM/RTM) get three proposed restrictions worth flagging early: services limited to established patients only, a separate initiating visit required before monitoring begins, and — the one with real operational teeth — billing restricted to employed clinical staff, not contracted or third-party vendor staff. CMS is also considering collapsing RPM and RTM codes into four new G-codes. Any organization running remote monitoring through an outsourced vendor arrangement (a common model precisely because it’s cheaper to scale than hiring in-house) should treat this as the item to resolve first, not last — restructuring a staffing model takes longer than updating a claim form.

Coding changes to get ahead of

• The G2211 complexity add-on moves from a flat-rate standalone code to a modifier (CMS is calling it MOD1), applying a 16% increase across all E/M levels — a charge-master and claims-logic change, not just a fee update.
• A new ACO-specific modifier (MOD2) adds a further 32% for practitioners in Shared Savings Program or LEAD Model ACOs — relevant only if you track ACO attribution today; if you don’t, this is a reason to start.
• Advance care planning gets new HCPCS codes separating clinical-staff time from practitioner time; existing CPT 99497–99498 would apply only to practitioner-performed work going forward.

The quieter structural change: MIPS is being phased out

CMS is proposing to terminate the Merit-based Incentive Payment System after 2028, replacing it for non-APM clinicians with mandatory MIPS Value Pathways (MVPs) starting 2029. MVPs trim required quality measures from six to four (drawn from a pool of roughly 78 CMS-designated core measures) but keep the same underlying cost and quality reporting burden — this is a timeline shift, not a burden reduction. 2027 is early enough to start mapping which MVP your specialty will likely fall under rather than waiting for the mandate to arrive.

What to do before January 1

1. Model the conversion-factor impact against your actual CY2026 CPT mix, not the headline percentage — the real exposure varies a lot by specialty and payer mix.
2. Audit same-day E/M-plus-procedure billing patterns now and flag which providers and specialties carry the most exposure to the proposed 50% reduction.
3. If remote monitoring runs through a third-party vendor, start evaluating an in-house staffing path or a compliant restructuring before enforcement begins — this one takes months, not weeks.
4. Update charge description master and claims-scrubbing logic for the G2211/MOD1/MOD2 modifier changes ahead of the final rule, so the system is ready the week it publishes.
5. Track the final rule against this proposed version when it lands in November — treat every number here as directional until then.

None of these changes are individually dramatic. Together, they’re the kind of rule where the gap between "we read the fact sheet" and "our claims system is actually ready" widens fast — and it’s usually revenue cycle, not compliance, that absorbs the difference in January.
