Aetna cuts the CT technical component 15% on Sept. 1 — and it reaches OPPS, not just the fee schedule
Aetna's June 2026 OfficeLink Updates set a 15% reduction to the technical component of CT services billed with modifier CT, effective September 1, 2026, applied across both the physician fee schedule and OPPS for commercial and Medicare members.

Aetna will apply a 15% payment reduction to the technical component of CT services billed with modifier CT, effective September 1, 2026. The change appears on page 8 of the insurer’s June 2026 OfficeLink Updates, and Aetna states it “applies to both our commercial and Medicare members.”
The mechanism is narrow but the reach is not. Per the notice, the reduction hits “the technical component (TC) of the service,” “the TC portion of global billing,” and computed tomography imaging services — and it applies to “both the Medicare Physician Fee Schedule (MPFS) and the Outpatient Prospective Payment System (OPPS).” That OPPS line is what carries the change into the outpatient facility world, where the technical component is the facility’s revenue; for any center billing the TC under OPPS, this is a direct cut to that line, not a physician-side adjustment.
The trigger is the scanner, not the procedure. Aetna writes that “modifier CT is required when CT imaging is performed using equipment that doesn’t meet the National Electrical Manufacturers Association (NEMA) XR 29-2013 ‘Smart Dose’ standards.” Compliant equipment doesn’t carry the modifier and isn’t reduced; the haircut lands only on CT performed with non-conforming scanners. Aetna frames the move as alignment, not a new penalty: “CMS requires a 15% reduction for CT services billed with this modifier, and we’re aligning our payment approach accordingly.” The insurer says fuller detail will sit in its Multiple Procedure Reductions for Imaging and Diagnostic Procedures Payment Policy on Availity beginning September 1, 2026.
For imaging-equipped centers — pain, orthopedic, and spine programs that run their own CT — the operator question is the same one CMS posed when it created the modifier: is the scanner Smart Dose-compliant? If it is, nothing changes. If it isn’t, every modifier-CT claim to an Aetna commercial or Medicare member loses 15% of the technical component starting September 1, and the math on a compliant replacement scanner becomes a Q3 capital decision rather than a someday one.
