Every January 1st, a new CPT code set takes effect, and every January the same scramble happens: superbills reference deleted codes, EHR fee schedules lag behind, and claims start denying for codes payers haven’t loaded yet. The 2026 CPT code set is a larger-than-usual update — 418 total changes — so it’s worth understanding the shape of it before claims start going out under the new codes.
The numbers
The American Medical Association’s 2026 CPT code set includes 288 new codes, 84 deletions, and 46 revisions, for 418 total changes, effective January 1, 2026. That’s a meaningfully larger release than a typical year, driven mostly by two categories: Proprietary Laboratory Analyses (PLA) codes, which make up roughly 27% of the new codes, and Category III codes for emerging technology and procedures, which account for more than a quarter of new codes on their own.
Where the changes concentrate
Three specialties see the largest share of changes this year: interventional radiology, diagnostic radiology/imaging, and pathology/lab. Audiology, urology, cardiology, and orthopedics also see meaningful updates. A few specific categories worth flagging directly:
- Remote patient monitoring (RPM): new codes covering shorter monitoring windows — as little as 2 to 15 days within a 30-day period, rather than requiring a full 16-day minimum — reflecting how RPM programs actually operate in practice now.
- AI-assisted diagnostics: new codes for algorithmic/AI-assisted analysis in specific clinical contexts, including coronary plaque assessment, cardiac risk analysis, burn wound imaging, and cardiac dysfunction detection. This is a new frontier for CPT and one to watch closely, since payer coverage policies for these codes are still catching up.
- Hearing devices: a dozen new codes reflecting more patient-centered approaches to hearing device fitting and follow-up support.
- Lower extremity revascularization: a substantial modernization of this code family reflecting how these procedures are actually performed in outpatient settings today.
- Behavioral health telehealth: expanded appendix listings covering both audio-video and audio-only delivery options.
We haven’t reproduced the specific new code numbers here — the CPT code set is copyrighted by the AMA, and the safest source for the actual numbers is your current-year AMA CPT manual or your EHR/clearinghouse’s official code-set update, not a summary blog post. What matters for planning purposes is knowing where to look closely.
What to actually do before January 1
- Get the official 2026 CPT manual (or confirm your EHR vendor has licensed and loaded the update) and review the specialty sections relevant to your practice specifically, rather than assuming a general summary covers what you bill.
- Confirm with your EHR/PM vendor that deleted codes are actually removed from active fee schedules and superbills — a deleted code left active is one of the most common sources of denials in the first weeks of a new year.
- Check payer coverage policies for any new codes you expect to bill early, especially in the newer categories like AI-assisted diagnostics and RPM — coverage and reimbursement rates for brand-new codes often lag the code’s effective date by weeks or months.
- Train staff on the codes they’ll actually use, not the full 418-change list — a focused session on your top 20-30 billed codes and any changes affecting them is far more useful than a general overview.
- Watch denials closely in January and February specifically for the code families most affected by this year’s update, since that’s where fee-schedule lag and documentation-specificity mismatches show up first.
Takeaway
418 changes is a bigger-than-usual CPT update, concentrated in imaging, pathology, and a handful of emerging-technology categories like AI-assisted diagnostics and flexible RPM windows. The practical risk isn’t the total size of the update — it’s whether your specific fee schedule, superbills, and payer contracts have actually caught up to it by January 1.
