$139.06

National (GPCI 1.000)

Office-only: CMS developed no facility practice-expense RVUs for G0166 (NA indicator), so the file’s facility amount repeats the Office (non-facility) one.

The national PFS baseline was $139.06 for HCPCS G0166 in the Office (non-facility) setting and $139.06 in a facility under the Q4 2015 Physician Fee Schedule, effective October 2015. These are the national allowed amounts before locality (GPCI) adjustment; sequestration is excluded.

National Q4 2015, GPCI 1.000. Rows are provider types with at least 1% of G0166’s Medicare services in CMS’s CY2024 Physician & Other Practitioners data; each % applies before the 80/20 split and sequestration.

Is $139.06 what a practice actually receives?

It's the national allowed amount—the starting point. Medicare pays 80% of it ($111.25) and the patient owes 20% coinsurance ($27.81). Sequestration trims Medicare's share by about 2%, your locality's GPCIs scale the total up or down, and the expected-payment calculator applies all three. That payment is practice revenue that covers staff, space, equipment, and billing. It isn't the clinician's take-home pay. The practice-expense RVU above is CMS's estimate of that overhead share.

What's the non-participating amount for G0166?

$132.11 in the Office (non-facility) setting—95% of the $139.06 participating fee schedule amount above. A participating provider takes the fee schedule amount as payment in full on every claim. A non-participating provider is paid this reduced amount, but chooses claim by claim whether to accept assignment. See participating vs non-participating.

What's the limiting charge for G0166?

$151.93 in the Office (non-facility) setting—the ceiling on what a non-participating provider can bill the patient on an unassigned claim. That's 109.25% of the $139.06 amount above. The non-participating amount is 95% of the fee schedule rate ($132.11), and the statutory cap is 115% of that. See limiting charge.

How each change is split
The chips under each change split the Office (non-facility) move into the conversion factor's share, which CMS sets for every code, and G0166's own work, practice-expense and malpractice RVUs. CMS doesn't publish this split; we derive it from each release's RVUs and conversion factor. We apply the new conversion factor to the earlier RVUs first, then price each RVU change at the new conversion factor. Another order would move a few cents between columns, but every total stays the same.
When does this rate change?

CMS publishes a fee schedule release every quarter (January, April, July, October), and each is versioned here. See what changed each release, or get an email when a new release moves rates.

The G0166 rate last moved in Q1 2026. See its rate history.
