Q3 2015 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

CPT 36450 has a work RVU of 2.23, a non-facility practice expense RVU of 0.88, a facility practice expense RVU of 0.88 and a malpractice RVU of 0.31—for total non-facility RVUs of 3.42 and total facility RVUs of 3.42 in the Q3 2015 release.

amount = (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.

Release Q3 2015

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, and never as zero.

Payment review for 36450 Copy link

Three published payment rules can change what 36450 allows on a claim: facility-only practice-expense pricing, the standard multiple-procedure reduction 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.

What to reconcile

  • Check the place of service: CMS publishes no office (non-facility) practice-expense amount for this code, so it prices in a facility setting only.
  • Rank the claim’s procedure lines before calling this one short-paid: ranked below a higher-valued procedure on the same date it prices at $61.14 rather than $122.28 nationally at GPCI 1.000, which is the rule working rather than a payer error.
  • Check for documentation on file before appealing an assistant-at-surgery denial: payment on the -80 or -AS line is restricted for this procedure unless medical necessity is established.
  • Reprice the line against the release, locality, setting, modifier and participation status that applied to the date of service before treating any difference as an underpayment.

Payment rules

Global period: what 36450's fee already covers Copy link

XXX Does not apply

The global surgery concept does not apply to this code.

Billing policy Copy link

What 36450's billing-policy indicators mean. These show for every code, priced or not: a restriction like "bilateral not allowed" still matters on a carrier-priced code. See modifier amounts below for the dollar figures these support.

Policy Value What it means
Bilateral surgery 0 No bilateral adjustment. The 150% bilateral payment adjustment does not apply to this procedure.
Assistant at surgery 0 Restricted without documentation. Payment for an assistant at surgery is restricted for this procedure unless supporting documentation establishes medical necessity.
Co-surgeons 0 Not permitted. Medicare does not recognize co-surgeons (modifier 62) for this procedure.
Team surgery 0 Not permitted. Medicare does not recognize a surgical team (modifier 66) for this procedure.
Multiple procedures 2 Standard reduction applies. The same standard ranking-and-reduction rule as indicator 1 applies to this procedure when billed with others on the same date.
Professional/technical split 0 No PC/TC split. This is a physician service code; the professional/technical split does not apply, and the code is billed as a single service.

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

National non-facility amounts for the modifiers this code's indicators support. 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.

Modifier What it means Amount
-26/TC Professional/technical split Not payable
-50 Bilateral procedure Not payable
-80/81/82 Assistant surgeon (physician) (16%) $19.56 If documented
-AS Assistant at surgery (PA, NP, or CNS) (13.6%) $16.63 If documented
-62 Co-surgeons, each Not payable
-66 Team surgery Not payable

These apply standard MPFS percentages—assistant surgeon 16%, co-surgeon 62.5%, bilateral 150%—to the national non-facility amount above, and require both the RVU inputs and the applicable payment rule as evidence. They are derived here rather than read from a CMS column: 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 pays it only when supporting documentation of medical necessity is submitted—an unpaid claim without that documentation is not an underpayment.

Computed from the Q3 2015 CMS release

Medicare allowed amount

What Medicare recognizes as the full price for 36450 in the office (non-facility) setting. Every figure below derives from it.

$122.28
Medicare's share

80% of the allowed amount, before the ~2% sequestration cut.

$97.82
Patient coinsurance

The remaining 20%, once the annual Part B deductible is met. Medigap or Medicaid often covers it.

$24.46
Limiting charge

The ceiling a non-participating provider can bill a patient on an unassigned claim—109.25% of the allowed amount.

$133.60

National Q3 2015 figures at GPCI 1.000. Adjust for your locality and sequestration, or expand the explanations below for each figure in full.

Is $122.28 what a practice actually receives?

It's the national allowed amount—the starting point. Medicare pays 80% of it ($97.82) and the patient owes 20% coinsurance ($24.46). 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. What lands is practice revenue: staff, space, equipment and billing, not clinician take-home pay. The practice-expense RVU above is CMS's estimate of that overhead share.

What's the non-participating amount for 36450?

$116.17 in the office (non-facility) setting—95% of the $122.28 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 36450?

$133.60 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 $122.28 amount above. The non-participating amount is 95% of the fee schedule rate ($116.17), and the statutory cap is 115% of that. See limiting charge.

Common payment questions Copy link

Why would a Medicare claim for 36450 be denied or paid less?

These come from CMS indicators on this page, not general billing advice.

Payer-specific coverage and documentation rules live outside these files, so a claim that clears every check here can still be denied on other grounds.

Source & method

Show sources

This page uses CMS's Medicare Physician Fee Schedule Q3 2015 release (effective July 2015). National baselines use GPCI 1.000 and exclude sequestration. Status and payment instructions determine whether a national amount is established; blank RVUs stay blank. Releases are immutable: historical evidence remains tied to the specified release. Modifier amounts apply standard MPFS percentages to this code's billing indicators. We derive them here rather than read them from CMS, so confirm them against the current Claims Processing Manual before relying on them for payment. Our methodology covers the depth: sourcing, parsing, versioning, and how we cross-check claims before they ship.
