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 Hawaii the office and hospital physician lines for this CPT differ by $213.43.
National vs Hawaii
Where Hawaii ranks for this CPT
Colonoscopy (Diagnostic) and how Hawaii is priced
Hawaii is priced through a single locality with geographic adjustments well above the mainland norm, driven largely by the practice expense side: rent, staff wages, and supplies all cost more across the islands. Unlike Alaska, Hawaii does not carry a special statutory floor, but its indices still place it among the higher-cost states in the fee schedule. Every island shares the same locality, so Honolulu and Hilo publish the same Medicare-approved amounts. The real variable for residents is which island the care is on, not the rate itself.
Oahu holds the bulk of Hawaii's hospital capacity and nearly all of its subspecialty care, so neighbor island residents routinely fly to Honolulu for procedures, adding airfare and hotel costs to the medical bill. A small number of systems dominate the market, and physician recruitment to the islands is a chronic challenge. For complex or rare conditions, some patients travel on to the mainland West Coast.
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 Hawaii: questions
Hawaii is a single Medicare locality for this fee schedule. The 2026 physician rate for CPT 45378 is $379.76 in an office and $166.33 in a hospital, statewide. A ZIP lookup still confirms the locality mapping.
Not on the physician fee schedule. Hawaii 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 $76 for the office physician line or $33 for the hospital physician line in Hawaii. Medigap may cover that 20%. This is not the hospital facility fee.
No. $379.76 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. Hawaii ranks #36 of 51 states on the physician line (within 2% of the national office rate of $378.10).
