-0.2% vs nationalAverage of 4 localities. Office range $305.72–$335.97.
What the whole procedure costs
The rate above is the physician’s fee on its own. The facility bills separately, and for most procedures the facility is the larger half of the bill. These are 2026 national Medicare amounts.
Choosing a surgery centre over a hospital saves about $429 on the Medicare allowed amount for upper endoscopy (egd). Ask whether your procedure can be done at an ambulatory surgery centre.
This is Medicare's separate payment to the facility on top of the physician's fee. Medicare allowed amounts are not what an uninsured patient is charged, and not a quote. Private plans typically allow more.

What these numbers are
Every figure on this page is a 2026 Medicare allowed amount: the physician line comes from the Physician Fee Schedule adjusted by geographic practice-cost indices, and the facility totals come from the CMS hospital outpatient (OPPS) and ambulatory surgery centre rates. None of them is a hospital chargemaster price, your insurer's contracted rate, or a quote. Anesthesia, pathology, imaging reads and follow-up care are billed under their own codes when they apply, and an inpatient stay is paid a different way again. In Illinois the office and hospital physician lines for this CPT differ by $204.93.

Upper Endoscopy (EGD) and how Illinois is priced
Illinois uses one of the more detailed locality maps in the Midwest: Chicago has its own locality, the suburban collar counties are priced separately, the East St. Louis area carries its own locality tied to the St. Louis market, and the rest of the state shares a fourth. Approved amounts step down noticeably from the city and suburbs to downstate, so the same procedure prices differently in Chicago, Naperville, Belleville, and Springfield. This four-way split makes Illinois one of the states where a ZIP-level check genuinely changes the answer. Downstate rates align more closely with neighboring rural states than with Chicagoland.
Chicago is one of the country's great medical hubs, with multiple academic medical centers and deep specialist supply, and its suburbs support large competing systems of their own. Downstate Illinois is a different market: smaller cities like Peoria, Springfield, and Champaign serve wide rural areas, and the Metro East suburbs orient toward St. Louis providers. Where you sit on that map shapes both price and choice.
This procedure: An upper endoscopy, or EGD, passes a thin flexible camera through the mouth to examine the esophagus, stomach, and the first part of the small intestine. It investigates problems like persistent heartburn, swallowing difficulty, unexplained anemia, or upper abdominal pain. You receive sedation through an IV, the exam itself takes 10 to 20 minutes, and you go home the same day once the sedation wears off, needing a driver.
What Is Upper Endoscopy (EGD)?
An upper endoscopy, or EGD, passes a thin flexible camera through the mouth to examine the esophagus, stomach, and the first part of the small intestine.

You receive sedation through an IV, the exam itself takes 10 to 20 minutes, and you go home the same day once the sedation wears off, needing a driver.
What Affects the Cost
- –The choice between a hospital outpatient department and a freestanding endoscopy center is the single biggest price lever.
- –Sedation billed by a separate anesthesia provider, especially propofol given by an anesthesiologist or CRNA, adds a significant independent charge.
- –This code is the diagnostic-only exam; if the doctor takes even one biopsy the procedure is recoded to 43239 at a higher rate plus lab fees.
- –Pre-procedure consultation visits with the gastroenterologist are billed separately from the endoscopy itself.
- –Facility fees vary more than physician fees, so the same doctor can cost very different amounts at different locations.
Questions to Ask Before Booking
- 1.Can this be scheduled at a freestanding endoscopy center rather than the hospital, and what is the facility fee at each?
- 2.Who provides the sedation, what type is used, and are they in my network?
- 3.If you take biopsies during the exam, how much does the procedure code and pathology add?
- 4.Is prior authorization required and has it been obtained?
- 5.What is the all-in estimate including physician, facility, anesthesia, and pathology?

After the Part B deductible, coinsurance is usually 20% of the allowed amount: about $64 for the office physician line or $23 for the hospital physician line in Illinois. Medigap may cover that 20%. This is not the hospital facility fee.
No. $321.87 is only the physician's share. Adding Medicare's facility payment brings the total to about $1,037 in a hospital outpatient department, or about $608 at an ambulatory surgery centre. Anesthesia, pathology and other codes billed the same day are extra. Illinois ranks #34 of 51 states on the physician line (within 2% of the national office rate of $322.65).
