Compared with Medicare
$950.10 is Medicare's 2026 national base rate for this service in a hospital outpatient department, including the patient's share and before the local wage adjustment. The median hospital cash price, $1,209.12 across 667 hospitals, is 1.3× that.
Researchers often measure hospital prices as a multiple of Medicare's rate, and it is a concrete number to mention when you ask a hospital for a cash discount. Source: CMS.
What it is
This is a routine colonoscopy for someone with no symptoms and no high-risk factors, done to find and prevent colorectal cancer. G0121 is a Medicare screening code; for people at average risk Medicare covers it once every 10 years, or 4 years after a screening sigmoidoscopy.
What the price covers
The facility price usually covers the procedure room and recovery. The gastroenterologist, anesthesia, the bowel-prep medicine and any pathology are usually billed or bought separately.
Why prices differ
Prices differ between hospital outpatient departments and ambulatory endoscopy centers and with the type of sedation. Commercial plans and many self-pay bills use 45378 with a screening modifier instead of G0121, so hospitals may price the two codes differently.
What to ask
Ask whether the self-pay price for HCPCS G0121 includes the doctor and anesthesia fees, and what the price becomes if a polyp is removed.

Common questions
Why might my bill show 45378 instead of G0121?
G0121 is used mainly for Medicare. Most commercial plans and many self-pay bills list the same screening as 45378 with a screening modifier, so it is worth comparing both codes.
What happens if a polyp is removed during screening?
The procedure may be re-coded as diagnostic or therapeutic (for example 45380 or 45385) and a pathology fee is added, which usually raises the total.
How much does Medicare pay for HCPCS G0121 (Screening colonoscopy)?
$950.10 is Medicare's 2026 national base rate for this service in a hospital outpatient department, including the patient's share and before the local wage adjustment. The median hospital cash price, $1,209.12 across 667 hospitals, is 1.3× that.
