Quick take
- Signature Healthcare Brockton Hospital is the lowest-cost option at $404 - $205 below the state median, just by choosing where you go.
- Ask for the cash price if your deductible isn't met - the median cash price here is $609, and it's often lower than what insurance pays before your deductible is satisfied.
- This dataset covers hospitals only - freestanding ASCs, which routinely run 30-60% cheaper for the same procedure, aren't included, so it's worth asking your doctor whether one is an option.
Massachusetts has the highest commercial hospital reimbursement rates in the country, driven by extreme labor costs, the dominance of Mass General Brigham (Partners HealthCare), and a regulatory environment that has struggled to contain negotiated rate growth. The state has enacted multiple price transparency and rate growth laws aimed at curbing this pattern. Self-pay cash discounts in Massachusetts tend to be proportionally larger than in other high-cost states. Colonoscopy pricing is particularly sensitive to screening vs. diagnostic coding. A screening colonoscopy is typically covered at 100% under preventive care benefits, but if a polyp is removed or a finding is documented during the same visit, the claim is often re-coded as diagnostic - triggering your deductible and coinsurance. Ambulatory surgery centers perform over 70% of colonoscopies nationally and charge substantially less than hospital outpatient settings.

Why prices vary - and what it means for your coverage
A small number of hospitals (1) report prices above $2,538, including Curahealth Stoughton LLC at $3,728, which drives most of the overall spread - excluding them, most facilities cluster in a much tighter band. Setting matters too: the median outpatient price is $586 versus $609 inpatient, so where a procedure happens often matters more than which hospital you pick. The biggest swing for this procedure is screening versus diagnostic coding - a polyp removed during a routine screening can recode the whole visit as diagnostic and trigger cost-sharing you weren't expecting.
On top of the facility price, your actual bill depends on your deductible, your out-of-pocket maximum, and whether every provider involved - not just the facility - is in-network.
| Your situation | Estimated out-of-pocket |
|---|---|
| Deductible not yet met | ~$609 |
| Deductible met - 20% coinsurance | ~$122 |
| Out-of-network provider | $1,340+ |
