CPT 2026 Code Changes: 418 Updates Your Practice Needs to Know
The 2026 CPT code set brought 288 new codes, 84 deletions, and 46 revisions — plus a full rebuild of lower-extremity revascularization and the first AI-service codes. Here is what changed and how to prepare.
Every January 1, the CPT code set turns over — and 2026 is a heavy year. With 418 changes, including a ground-up rebuild of a major procedure section and the arrival of AI-service codes, practices that don't refresh their charge masters and superbills start bleeding denials fast. Here's the landscape.

The 2026 numbers
418 total changes took effect January 1, 2026. Remember the rhythm: CPT updates every January 1; ICD-10-CM updates every October 1. Practices that keep both current avoid the two predictable denial spikes each year — see our companion piece on the ICD-10-CM 2026 updates.
The big changes
- Lower-extremity revascularization rebuilt — 46 new territory-based codes (37254–37299) replace the old structure. Vascular and cardiology practices must remap.
- Expanded remote monitoring — continuing the shift toward shorter-duration RPM billing.
- AI-driven services — the code set now recognizes certain artificial-intelligence-enabled medical services.
The denial risk
Two failure modes recur every January: billing a deleted code (instant rejection) and failing to adopt a new, more specific code (lower pay or scrutiny). The revascularization rebuild is especially dangerous — an entire section's numbers moved, and stale templates will reject en masse.
When a whole section is renumbered, your superbill becomes a liability overnight. Remap before the first claim goes out.
How to prepare
- Load the 2026 CPT set into your EHR and practice-management system.
- Remap deleted codes to their 2026 replacements, especially in vascular/cardiology.
- Update superbills, order sets, and EHR favorites.
- Brief coders on the revascularization rebuild and new service categories.
- Audit early-January claims for rejections tied to old codes.
Staying current across both code sets is exactly what professional medical coding and revenue cycle management keep locked down.

The bottom line
418 changes is a lot of surface area, and the revascularization rebuild alone can wreck an outdated charge master. Load the set, remap deletions, refresh superbills, and coach coders — and January becomes routine instead of painful. Start with a free billing audit.

A comprehensive rebuild of the lower-extremity revascularization section into 46 territory-based codes (37254–37299), expanded remote-monitoring codes, and new codes for AI-driven medical services.
January 1, 2026. Unlike ICD-10-CM (which updates October 1), the CPT set updates each January 1.
CPT codes describe the procedures and services you perform (what you did); ICD-10-CM codes describe the diagnosis (why you did it). Both must be current and must support each other on the claim.
