HCPCS G0453 Medicare rate in Q3 2023

Rates by locality Copy link

The national baseline uses GPCI 1.000. These locality-adjusted allowed amounts use each payment locality's own GPCIs. Select a state to see its localities.

Q3 2023 amounts, computed with each locality's own GPCIs, before the ~2% sequestration cut. A state with more than one payment locality shows a range—its tile is colored by the mean across those localities, which is a shading choice, not an amount anyone is paid.

How this amount is computed Copy link

HCPCS G0453 has a work RVU of 0.60, a non-facility practice expense RVU of 0.30, a facility practice expense RVU of 0.30 and a malpractice RVU of 0.04—for total non-facility RVUs of 0.94 and total facility RVUs of 0.94 in the Q3 2023 release.

The formula is: (work RVU × work GPCI + PE RVU × PE GPCI + MP RVU × MP GPCI) × conversion factor. National amounts use GPCI = 1.000. To price an RVU figure of your own, use the RVU-to-dollars converter.

Every rate combines three parts: work (the clinician’s time, skill and effort), practice expense (office overhead—higher when the service is done in a doctor’s own office), and malpractice (the share of liability-insurance cost). A blank means CMS publishes no national number for that part. Read it as unknown, never as zero.

The global surgery concept does not apply to this code.

Billing policy Copy link

These billing-policy indicators explain how G0453 is treated. They apply whether the code is nationally priced or carrier-priced: a restriction like "bilateral not allowed" still matters on a carrier-priced code. See modifier amounts below for the dollar figures these support.

Modifier amounts: -26/TC, -50, -80/81/82, -AS, -62, -66 Copy link

National Office (non-facility) amounts for the modifiers this code's indicators support. These are single-line modifiers only. -51 (multiple-procedure reduction) depends on the other codes on the same claim, so it's a claim-level number rather than a per-code one. Use the calculator for a locality-adjusted, sequestration-aware amount.

Not payable with G0453: -26/TC (professional/technical split); -50 (bilateral procedure); -62 (co-surgeons, each); -66 (team surgery).

Each amount applies a standard MPFS percentage (assistant surgeon 16%, non-physician assistant at surgery 13.6%, co-surgeon 62.5%, bilateral 150%) to the national Office (non-facility) amount above. CMS doesn't publish these as a column; Localis derives them, so check them against the current Medicare Claims Processing Manual before relying on them for payment. A row marked If documented carries the ordinary percentage, but this code's CMS indicator allows it only when documentation of medical necessity is submitted. Without that documentation, an unpaid claim is not an underpayment.

Payment review for G0453 Copy link

Two published payment rules can change what G0453 allows on a claim: facility-only practice-expense pricing and documentation-restricted assistant-at-surgery payment. Each is a legitimate reason for a paid amount to differ from the fee-schedule amount on this page.

Why G0453's rate changed Copy link

National baseline (GPCI 1.000) · Office (non-facility) · Before sequestration

G0453's national amount rose $5.65 (+21.6%), from $26.20 in Q1 2013 to $31.85 in Q3 2023. Changes to the conversion factor, which CMS sets for every code, took $0.10 off. CMS revaluing G0453 itself added $5.75: +$3.38 from work RVUs, +$2.03 from practice-expense RVUs and +$0.34 from malpractice RVUs. The most recent change came in Q1 2023: −$1.03 (−3.1%), with −$0.69 from the conversion factor and −$0.34 from 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.

Contracted rate: % of Medicare Copy link

Commercial contracts are often written as a percentage of Medicare ("115% of Medicare"). Enter yours to see what it means for G0453. A contract benchmarked to the fee schedule applies it to your locality's allowed amount, not the $31.85 national baseline; the calculator finds that amount from your service ZIP.

How G0453 compares with other codes Copy link

Against every code with a national PFS amount in Q3 2023 · National baseline · Before sequestration

43.2% Highest vs. lowest locality

G0453's Office amount is 43.2% higher in its highest-paid payment locality than in its lowest. That spread is narrower than 56% of the 7,230 codes compared; the median spread is 44.2%. How much a code's amount varies by locality depends on its mix of work, practice-expense and malpractice RVUs, since each has its own GPCI.

+21.6% Since Q1 2013

G0453's Office amount rose 21.6% from Q1 2013 to Q3 2023. Over the same period, the median code's amount rose 0.4%. That's higher than the change for 95% of the 6,467 codes priced in both releases.

These comparisons cover every code with a national Physician Fee Schedule amount: status A, R or T, with no blank RVUs. The locality comparison leaves out codes with an OPPS cap, because the cap, not the GPCIs, can set their amount in some localities.
