Self-pay patients in Rhode Island often have access to significantly discounted rates for knee replacement surgery. Under federal price transparency rules (45 CFR § 180.50), hospitals must publish their discounted cash prices alongside standard charges.

For insured patients, the negotiated rate between your plan and the hospital determines your cost share. If you haven't met your deductible, you may pay more than the cash price. It's worth asking the hospital whether their self-pay rate is lower than what your insurance would charge — some patients save money by not filing a claim.
