Domestic Steering: Rural and Exurban Hospitals, Independent Surgery Centers, and the Price Variation That Creates the Opportunity

The hospital price transparency data that became fully machine-readable under CMS requirements in 2024 reveals price variation within the domestic market that most employers and TPAs have not attempted to capture. For scheduled, non-emergency procedures, steering members to lower-cost domestic facilities produces 20 to 50 percent savings with comparable quality outcomes. The savings are moderate relative to cross-border care but carry lower operational complexity and fewer member acceptance barriers. Domestic steering is the cost management strategy that requires the least behavioral change from members while delivering meaningful savings.

The Price Transparency Data

#

Hospital price transparency files now show commercial negotiated rates for common scheduled procedures across facility types and geographies. The variation within a single metropolitan area can be 200 to 300 percent between the most expensive and least expensive facility for the same procedure using the same CPT code. An analysis of Transparency in Coverage data for hip and knee replacement at hospitals in Dallas found that prices ranged from $14,306 to $56,695 across different insurers at the same hospital, representing a fourfold difference. Across hospitals in the same market, the variation is even wider.

The RAND Hospital Price Transparency Study documented this variation systematically. In 2022, commercial prices relative to Medicare ranged from below 170 percent in Arkansas to above 300 percent in California, Florida, New York, and several other states. Within states, the interquartile range (25th to 75th percentile) of hospital prices relative to Medicare represents a 45 percent potential spending reduction. A self-funded plan that steers members from the 75th percentile hospital to the 25th percentile hospital in the same market saves 45 percent on facility costs without changing the procedure, the diagnosis, or the quality of care.

The ambulatory surgery center versus hospital outpatient department differential is particularly pronounced for orthopedic procedures. A 2024 study analyzing privately negotiated facility fees disclosed under the Transparency in Coverage Act found that on average, hospital facility fees are more than double ASC facility fees for common outpatient procedures. The analysis included prices from major national payers (Anthem/Blue Cross Blue Shield, Aetna, Cigna, UnitedHealthcare) and the top five payers by beneficiary count in every state. Mixed-effects modeling revealed that, on average and independent of procedure type, facility fees are $3,077 higher at hospitals compared with ASCs. For knee arthroplasty, the mean facility fee difference was $5,717.

Hand and upper-extremity procedures show similar patterns. A study presented at the AAOS 2024 Annual Meeting found that total costs were up to 45 percent lower when performed at ASCs compared to hospital outpatient departments. The total cost of arthroscopy procedures was $1,886 in ASCs versus $3,418 in HOPDs. Fracture procedures cost $3,887 in ASCs versus $5,976 in HOPDs. Facility fees, Medicare payments, and patient payments were all significantly lower at ASCs across procedure categories.

The Quality Evidence

#

The concern that lower-cost facilities produce lower-quality outcomes is addressable with data. Published outcomes research consistently shows that ambulatory surgery centers produce comparable or better outcomes than hospital outpatient departments for appropriate procedures. A 2024 study in the American Journal of Managed Care found that for colonoscopy, knee or shoulder arthroscopy, and cataract removal surgery, the mean rates of procedural complications within 90 days were not lower in hospital-based centers than in freestanding ambulatory surgery centers. The higher prices in hospital-based clinics are not balanced by higher quality.

For joint replacement specifically, research from Carey et al. found that costs were higher but postsurgical complications were lower for patients treated in ASCs compared with hospital outpatient departments. This finding inverts the expected relationship: the lower-cost setting produced better outcomes. The explanation lies in patient selection and facility specialization. ASCs perform high volumes of elective procedures on appropriately selected patients. Their protocols are optimized for the specific procedures they perform. Their infection control, anesthesia protocols, and recovery processes are refined through repetition.

Rural hospitals with adequate surgical volume also produce outcomes comparable to urban facilities for common procedures. The volume-outcome relationship in surgical quality is well-documented: facilities that perform more of a given procedure achieve better results. A rural hospital that performs 200 joint replacements per year may outperform an urban academic medical center where joint replacement is a small fraction of surgical volume. The quality evidence is essential for member acceptance and for the plan’s fiduciary defense of the steering strategy.

The Benefit Incentive Design

#

Domestic steering works in a level funded plan through benefit incentive design that makes lower-cost options financially attractive to members. The mechanisms are straightforward. First, reduced cost sharing for members who choose a designated lower-cost facility. A plan might waive the deductible entirely and reduce coinsurance from 20 percent to zero for members who use a designated ASC or preferred hospital. The member saves several thousand dollars in out-of-pocket costs. The plan saves ten thousand or more in facility fees. Both parties benefit.

Second, travel and lodging reimbursement for members who travel to a lower-cost domestic facility. A member in San Francisco whose plan designates an ASC in Sacramento for knee arthroscopy receives reimbursement for mileage, one night of hotel accommodation, and meals. The total travel cost is $300 to $500. The procedure savings is $5,000 to $15,000. The math favors the travel.

Third, concierge navigation to help members find and schedule at the designated facility. A member who receives a recommendation for shoulder surgery does not know which facilities are designated, what the price difference is, or how to schedule at an unfamiliar location. The TPA’s navigation service explains the options, schedules the appointment, coordinates the pre-operative testing, and confirms the logistics. The member’s experience is easier than navigating the default network on their own.

The incentive design must be embedded in the plan document, which defines covered services and cost-sharing structures. The plan document specifies the designated facilities, the cost-sharing differential, and the travel reimbursement policy. The TPA’s adjudication system must apply the incentive correctly, recognizing claims from designated facilities and applying the reduced cost sharing automatically. The communication to members must be clear: when you need a scheduled procedure, call the navigation line, and we will help you access lower-cost, high-quality care with zero out-of-pocket cost.

Operational Requirements and Implementation Cost

#

A TPA operating a domestic steering program needs several capabilities. First, a facility quality vetting process that identifies lower-cost facilities with acceptable quality outcomes. This requires access to price transparency data, quality metrics (CMS Star ratings, Leapfrog Group data, complication rates), and the analytical capability to integrate them. Data vendors like Turquoise Health provide cleaned and standardized transparency data. Quality data is publicly available from CMS and Leapfrog. The TPA must build or acquire the analytical layer that identifies the facilities where price and quality align.

Second, member navigation capability. This can be staffed internally (care coordinators who handle steering calls) or contracted through a vendor specializing in care navigation. The navigation capability must be available at the point of decision, when the member has just received a surgical recommendation and is scheduling the procedure. Retrospective outreach after the procedure is already scheduled is too late.

Third, travel and lodging coordination for members who use distant facilities. This can be handled by the navigation staff or contracted to a medical travel coordinator. The coordination includes booking travel, arranging accommodations, providing destination information, and confirming logistics with the facility.

Fourth, benefit design integrated into the plan document and claims adjudication logic. The plan document must define designated facilities, specify cost-sharing differentials, and authorize travel reimbursement. The adjudication system must recognize designated facilities by facility identifier and apply the correct cost sharing.

Implementation costs for a domestic steering program include facility vetting (one-time data acquisition and analysis), navigation staffing or vendor fees (ongoing, typically per-member-per-month or per-case), travel coordination (per-case), and technology investment (claims logic, member-facing tools). For a TPA operating across multiple employer clients, the fixed costs (data acquisition, technology) are amortized across the book of business. The variable costs (navigation, travel) scale with utilization.

At a representative 25-person plan with two qualifying procedures per year, implementation costs might run $5,000 to $10,000 annually (navigation staffing allocated across the book, travel coordination costs). Gross savings from steering two procedures from a 75th percentile hospital to a 25th percentile facility or ASC might run $15,000 to $40,000. Net savings after implementation costs: $10,000 to $30,000 per year for a 25-person plan. The ROI is positive in year one.
