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 $440 on the Medicare allowed amount for colonoscopy (diagnostic). 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 Tennessee the office and hospital physician lines for this CPT differ by $194.01.
National vs Tennessee
Where Tennessee ranks for this CPT
Colonoscopy (Diagnostic) and how Tennessee is priced
Tennessee's Medicare rates come from one statewide locality with below-average geographic indices, so Memphis, Nashville, Knoxville, and Chattanooga all publish the same approved amounts despite being four distinct metro markets. The uniform locality stretches across a state that spans two time zones and several regional economies. Nashville's boom has raised local practice costs faster than the statewide averages that feed the indices. For patients, the fee schedule is identical statewide; the markets around it are anything but.
Nashville is the corporate capital of American hospital operations, home to major for-profit chains, alongside a prominent academic medical center, while Memphis anchors care for the Mid-South including parts of Mississippi and Arkansas. Knoxville and Chattanooga serve East Tennessee, and the rural Cumberland Plateau and West Tennessee counties have seen multiple hospital closures. Cross-border patient flows into Tennessee's metros are heavy from every neighboring state.
This procedure: A diagnostic colonoscopy examines the entire large intestine with a flexible camera inserted through the rectum, looking for the cause of symptoms such as bleeding, chronic diarrhea, or abdominal pain, or following up an abnormal stool test. You complete a bowel-cleansing prep the day before, receive IV sedation, and the exam takes 20 to 45 minutes. This specific code means the doctor looked but did not remove or sample anything; you go home the same day with a driver.
What Is Colonoscopy (Diagnostic)?
A diagnostic colonoscopy examines the entire large intestine with a flexible camera inserted through the rectum, looking for the cause of symptoms such as bleeding, chronic diarrhea, or abdominal pain, or following up an abnormal stool test. You complete a bowel-cleansing prep the day before, receive IV sedation, and the exam takes 20 to 45 minutes. This specific code means the doctor looked but did not remove or sample anything; you go home the same day with a driver.
What Affects the Cost
- –Facility setting is the dominant variable: hospital outpatient departments routinely charge several times what freestanding endoscopy centers do.
- –Anesthesia billed separately, particularly monitored propofol sedation, adds a meaningful independent charge.
- –If any polyp or tissue is encountered and removed, the procedure converts to a higher-paying code (45380 or 45385) plus pathology fees.
- –The bowel prep kit may be a pharmacy cost, with prescription-only preps costing more than over-the-counter regimens.
- –A pre-procedure consult with the gastroenterologist is often billed as its own office visit.
Questions to Ask Before Booking
- 1.Is my procedure being ordered as diagnostic or screening, and what exactly will I owe under each?
- 2.If this follows a positive Cologuard or FIT test, will it be billed with the screening modifier so my cost sharing is waived?
- 3.What are the facility fees at the hospital versus the endoscopy center you use?
- 4.Who provides sedation and are they in network?
- 5.If you find and remove a polyp, what does my estimate become?

Colonoscopy (Diagnostic) in Tennessee: questions
Tennessee is a single Medicare locality for this fee schedule. The 2026 physician rate for CPT 45378 is $348.26 in an office and $154.25 in a hospital, statewide. A ZIP lookup still confirms the locality mapping.
Not on the physician fee schedule. Tennessee uses one locality, so the Medicare physician rate is the same from one end of the state to the other. What still changes is site of service (office vs hospital) and any facility fee the hospital bills on its own claim.
After the Part B deductible, coinsurance is usually 20% of the allowed amount: about $70 for the office physician line or $31 for the hospital physician line in Tennessee. Medigap may cover that 20%. This is not the hospital facility fee.
No. $348.26 is only the physician's share. Adding Medicare's facility payment brings the total to about $1,115 in a hospital outpatient department, or about $675 at an ambulatory surgery centre. Anesthesia, pathology and other codes billed the same day are extra. Tennessee ranks #7 of 51 states on the physician line (8% below the national office rate of $378.10).
