What the 2026 Medicare Changes Mean for Your California Practice

The 2026 Medicare Physician Fee Schedule took effect January 1, and the headline number sounds like good news. For the first time in years, the conversion factor went up. But the headline hides the part that actually affects your revenue, and a few changes coming later this year could quietly cost California practices money if nobody’s watching for them.

Here’s what Orange County and Southern California providers need to know.

The conversion factor went up, but it’s not a raise

For 2026, CMS set two conversion factors: $33.57 for clinicians in qualifying Advanced Alternative Payment Models and $33.40 for everyone else. Both include a one-time 2.5% bump from federal legislation, so most practices see a 3.26% increase on paper.

That sounds like a win after years of flat or shrinking rates. The problem is what’s underneath. Operating cost per physician rose more than 63% from 2013 to 2022, while the Medicare conversion factor moved up only 1.7% in that same stretch. A one-year increase doesn’t close a decade-long gap. And the 2.5% legislative bump expires unless Congress acts again, so 2027 could reverse it.

The takeaway for your practice: don’t budget as if reimbursement is recovering. Budget as if every dollar you’re owed needs to actually get collected, because the margin for waste is gone.

The telehealth billing change coming October 1

This is the one most practices will miss. Through December 31, 2026, rural health clinics and federally qualified health centers can still bill telehealth visits using the bundled code G2025, priced at $97.53 for 2026. But effective October 1, 2026, CMS requires those clinics to bill the individual CPT or HCPCS code for each distant-site telehealth service instead of the single G2025 code.

If your practice bills telehealth and you don’t update your coding workflow before October, claims will start getting denied for using a code that’s no longer accepted. That’s a hard deadline, and it’s the kind of change that doesn’t announce itself until the denials show up.

Medicare Advantage is where the real revenue leak is

About 35 million Americans are on Medicare Advantage in 2026, and that number keeps climbing. For California practices, MA plans are often the larger share of the patient panel, and they’re also where money gets lost.

Even when fee schedule rates rise, MA plans can reduce what you actually collect through prior authorization delays, downcoding, and denials. CMS did finalize some relief: starting in 2026, MA plans can no longer reopen and modify an already-approved inpatient admission except for clear error or fraud. That’s a real protection. But the day-to-day grind of MA denials and documentation disputes still raises your cost to collect on every claim.

The practices that protect their margin in 2026 are the ones tracking denial patterns by payer and appealing aggressively, instead of writing off denied claims as a cost of doing business.

New codes you need in your system now

CMS added new billing codes for 2026 that your practice management system needs to recognize, including new Advanced Primary Care Management add-on codes for behavioral health integration, updated remote monitoring codes, and 80 new ICD-10-PCS codes effective April 1. If your fee schedule tables and claim edits aren’t updated, you’ll see denials tied to outdated classifications.

This is exactly the kind of behind-the-scenes maintenance that falls through the cracks when a small practice is running on a thin staff.

How to stay ahead of it

The pattern across all of these changes is the same: 2026 rewards precision and punishes practices that aren’t watching the details. Higher denials, tighter documentation rules, and hard coding deadlines all hit the same place, your collections.
