CPT 2026: The Biggest Changes Coders Need to Know

The CPT 2026 code set, effective January 1, 2026, delivered 418 total changes — 288 new codes, 84 deletions, and 46 revisions. That’s a lot to absorb, so here’s a coder’s-eye view of the changes most likely to touch your work queue.

Lower extremity revascularization: a complete rebuild

The single biggest structural change is in vascular surgery. The long-standing lower extremity revascularization codes (37220–37235) were deleted and replaced with 46 new territory-based codes (37254–37299). The new framework organizes interventions into four vascular territories — iliac, femoral/popliteal, tibial/peroneal, and inframalleolar — and distinguishes straightforward lesions (stenosis) from complex ones (occlusion).

If you code for vascular surgery, interventional radiology, or cardiology, this is your top training priority. Vascular access, intervention, and intraprocedural imaging are bundled into the new codes, and arterial closure is not separately billable.

Remote physiologic monitoring gets flexible

The RPM family was modernized to reflect how monitoring actually happens. New code 99445 reports device supply and data transmission for shorter monitoring periods (2–15 days within a 30-day period), and 99470 covers treatment management in the 10–19 minute range. Codes 99453 and 99454 received revised descriptors. Practices that previously couldn’t bill because patients didn’t hit the old 16-day or 20-minute thresholds now have compliant options.

Coronary and aortic procedures restructured

Coronary therapeutic services underwent a major overhaul that consolidated work within a single coronary artery and deleted many add-on codes for additional vessels. TEVAR (thoracic endovascular aortic repair) coding was also restructured: catheter placement, radiologic supervision and interpretation, and proximal extensions are now bundled into the main procedure, and a new code covers thoracic branch endoprosthesis work. Cardiology and CV surgery coders should review the revised guidelines closely — the bundling logic changed, not just the code numbers.

AI is officially in the codebook

CPT 2026 formalizes reporting for algorithm-assisted services, including AI-driven coronary plaque assessment and perivascular fat analysis for cardiac risk, plus multispectral imaging analysis for burn wounds. Documentation expectations are evolving with these codes — records increasingly need to reflect algorithm involvement and physician oversight.

Other changes worth flagging

Endoscopic sleeve gastroplasty earned a Category I code (43889) with a 90-day global period — big news for bariatric programs.
SI joint fusion codes 27278 and 27279 were revised to clarify intra-articular versus transarticular device placement; 27279 now requires the device to pierce the cortices of the ilium and sacrum.
Nervous system procedures gained 11 new codes reflecting minimally invasive techniques, including percutaneous lumbar decompression with partial ligamentum flavum removal (62330/62331) and percutaneous balloon decompression of the median nerve for carpal tunnel syndrome with ultrasound guidance (64728).
Prostate biopsy codes (55705–55715) were restructured to specify approach (transrectal, transperineal, in-bore) and guidance method (ultrasound, MRI-fusion).
Hearing device services moved to a time-based framework.
Liver tumor ablation by irreversible electroporation graduated from Category III (0600T, deleted) to Category I code 47384.
Proprietary laboratory analyses made up the largest share of new codes — roughly 27% — so lab coders have their own reading list. New assays include neurofilament light chain (83884) and beta-amyloid and tau testing supporting dementia evaluation.

Your January-forward checklist

Run a gap analysis on your top 50 billed CPT codes against the deletion list.
Update chargemasters, fee schedules, and EHR order sets.
Train providers whose documentation feeds the restructured code families — especially vascular, bariatric, and any practice billing RPM.
Watch payer bulletins: coverage and reimbursement for new codes (especially AI-related and Category III) varies widely.

Code changes of this scale are also denial risks. The practices that audit their highest-volume families in Q1 are the ones that aren’t fighting recoupments in Q3.
