What Are the 2027 Medicare Payment Changes for Family Medicine?
As of July 2026, the CMS CY 2027 Physician Fee Schedule proposed rule (CMS-1848-P) introduces three changes that directly affect family medicine practices. The conversion factor would drop from $33.40 to $32.84, a 1.68% decrease. Same-day E/M visits billed with modifier 25 alongside a procedure would be paid at 50% of the lesser service. And the G2211 longitudinal complexity add-on would transition from a standalone code to a 16% modifier on the underlying E/M visit. The comment period closed September 14, 2026, and the final rule is expected this fall.
Same-day billing penalized. When a family medicine provider bills a sick visit with modifier 25 alongside a same-day procedure, the lesser service would be reimbursed at 50% instead of in full.
G2211 changes form. The $16 flat add-on becomes a 16% modifier on the E/M code, which changes the dollar value depending on the E/M level billed.
Conversion factor drops. The non-QP conversion factor falls from $33.40 to $32.84 as the one-year 2.5% statutory increase from 2026 expires.
What CMS Proposed on July 14
On July 14, 2026, CMS released the CY 2027 Medicare Physician Fee Schedule proposed rule, designated CMS-1848-P. For family medicine, the rule targets three revenue streams that define the specialty’s daily billing workflow.
First, the conversion factor drops. The proposed 2027 non-QP conversion factor is $32.84, down from $33.40 in 2026, a 1.68% decrease driven by the expiration of the temporary 2.5% statutory increase Congress enacted for 2026 under the Working Families Tax Cut legislation. The QP conversion factor drops to $33.17, a 1.19% decrease.
Second, CMS proposes reducing payment when a separately identifiable E/M visit with modifier 25 is billed on the same day as a procedure with a 0, 10, or 90 day global period. The lesser service would be paid at 50%. For family medicine, this targets one of the highest-volume billing patterns in the specialty: the patient who comes in for a sick visit and also has a minor procedure performed the same day.
Third, the G2211 visit complexity add-on would transition from a standalone code worth a flat $16 to a modifier that adds 16% to the underlying E/M visit. For lower-level E/M codes like 99212 and 99213, the 16% modifier may pay less than the current flat rate. For higher-level codes like 99214 and 99215, it may pay slightly more.
Why This Hits Family Medicine Harder Than Most Specialties
Family medicine is the most E/M-dependent specialty in outpatient medicine. Where a surgical specialty generates revenue from procedures with high per-unit payment, a family practice generates revenue from volume: hundreds of E/M visits per week, each carrying a relatively low individual payment. When the conversion factor drops by 1.68% across that volume, the annual revenue impact is significant even though the per-claim reduction looks small. And when the same-day modifier 25 payment is cut to 50%, it hits the exact workflow that defines a busy family practice day: the patient who presents for a problem visit and also needs a wart removed, a laceration repaired, or a joint injection. Our guide to billing CPT 99213 for family medicine covers the E/M documentation rules that sit underneath these same-day claims.
The G2211 transition is more nuanced. Family medicine practices that bill primarily at the 99213 and 99214 level will see the G2211 payment change depending on the final percentage. At 16%, a 99213 visit worth roughly $96 would add about $15 (slightly less than the current flat $16), while a 99214 visit worth roughly $146 would add about $23 (more than the flat $16). Practices with a heavy 99213 mix may lose a small amount per encounter; practices that bill higher levels may gain. The net effect depends entirely on your code distribution.
| Proposed change | Current (2026) | Proposed (2027) |
|---|---|---|
| Conversion factor (non-QP) | $33.40 | $32.84 (minus 1.68%) |
| Same-day E/M + procedure | Both paid in full with modifier 25 | Lesser service paid at 50% |
| G2211 add-on | Flat $16 standalone code | 16% modifier on the E/M |
| Status | In effect | Proposed, comments due Sept 14, 2026 |
The 2027 proposals target the exact billing workflows that define family medicine: same-day E/M with procedures, longitudinal care add-ons, and high-volume E/M visits. A billing partner that models your specific code mix against the proposed changes can show you the real revenue impact before January. Comparing quotes is free.
What Should Family Medicine Practices Do Now?
The rule is proposed, not final, but preparing now protects your practice regardless of the outcome.
1. Pull your modifier 25 same-day volume for the past 12 months. Separate E/M-plus-procedure claims from E/M-plus-preventive claims. The proposal targets procedures with 0, 10, or 90 day global periods, not preventive visit codes with XXX global periods.
2. Model the 50% reduction on your most common same-day procedure codes. Joint injections, lesion destruction, laceration repairs, and ear lavage are the most common family medicine procedures billed same-day with an E/M.
3. Run your G2211 utilization by E/M level. Calculate how the 16% modifier compares to the flat $16 at each E/M level you bill. If your mix is heavily 99213, the per-encounter G2211 revenue may drop slightly.
4. Update your documentation for modifier 25 compliance. CMS is clearly signaling scrutiny on same-day E/M billing. Every same-day visit must meet the separately identifiable standard with documentation that supports the medical necessity of a distinct E/M service.
5. Confirm which of your in-office procedures carry global periods. The modifier 25 proposal targets procedures with 0, 10, or 90 day global periods. Know which of your procedure codes are affected.
6. Evaluate your billing partner’s readiness. If you outsource billing, confirm your partner understands the proposed changes, can model the revenue impact for your practice, and has a plan to adjust workflows if the rule is finalized.
Common Misreadings of the Proposal
The first misreading is assuming the modifier 25 cut applies to every same-day sick-plus-well visit. The proposal targets E/M visits billed with procedures that have 0, 10, or 90 day global periods. Preventive medicine codes carry an XXX global period, so the standard well-child-plus-sick-visit or AWV-plus-problem-visit pairing may not be directly affected. Confirm the scope in the final rule.
The second is treating the proposal as final. CMS proposed the same modifier 25 reduction in the CY 2019 PFS and did not finalize it after significant pushback. The 2027 version could follow the same path.
The third is ignoring the conversion factor cut because it looks small. A 1.68% decrease across thousands of E/M claims per month compounds into real money, especially in family medicine where per-claim revenue is already low.
Frequently Asked Questions
When would the 2027 payment changes take effect?
If finalized, the changes apply to services on or after January 1, 2027. CMS released the proposed rule July 14, 2026, with comments accepted through September 14, 2026. The final rule usually arrives in the fall.
Does the modifier 25 cut apply to well visits plus sick visits?
The proposal targets E/M visits billed with procedures that carry a 0, 10, or 90 day global period. Preventive medicine codes carry an XXX global period, so the standard well-plus-sick visit pairing may not be directly hit. Confirm the scope in the final rule before assuming either way.
How much would the conversion factor drop?
The non-QP conversion factor would fall from $33.40 to $32.84, a 1.68% decrease. The QP conversion factor would fall from $33.57 to $33.17, a 1.19% decrease. Both drops are driven by the expiration of the one-year 2.5% statutory increase from 2026.
What is the G2211 modifier transition?
CMS proposes converting G2211 from a standalone add-on code worth a flat $16 to a modifier that adds 16% to the underlying E/M visit. For family practices billing primarily at the 99213 level, the per-encounter G2211 payment may decrease slightly. For those billing at 99214 and above, it may increase.
Did CMS propose this modifier 25 change before?
Yes. CMS proposed a similar same-day E/M payment reduction in the CY 2019 PFS proposed rule and did not finalize it. The 2027 proposal revives the concept. The AMA and AAFP opposed it then and are organizing responses again.
How do I model the revenue impact for my practice?
Pull 12 months of claims data, isolate every modifier 25 same-day E/M-plus-procedure claim, apply a 50% reduction to the lesser service, and calculate the annual difference. Then run your G2211 claims by E/M level and compare the flat $16 to 16% of each E/M payment. The combined number is your maximum exposure.
The 2027 proposals reward family practices that model their modifier 25, conversion factor, and G2211 exposure together and plan early.
