How Do I Benchmark My Cost Per Case Against Comparable Facilities?
To benchmark cost per case in a physician-owned ASC or OBL, you need data that does not exist inside your own operation. Your internal reporting shows what each case costs relative to your own history. It cannot show what comparable independent facilities at your volume and procedure mix pay to run the same case. That comparison and the one that makes the benchmark meaningful and requires invoice-level cost data from peer facilities operating under conditions similar to yours. Independent procedural facilities have rarely had access to it.
Why Internal Data Cannot Benchmark Cost Per Case Against the Market
Most physician-owned facilities track cost per case by dividing total operating costs by total case volume for a given period. That calculation is accurate. It tells the facility what it spent, on average, to produce each case during that period. However, it measures against the facility’s own prior periods rather than against what comparable independent facilities actually spend to produce the same cases. A facility whose cost per case has held steady for three years has demonstrated operational consistency. It has not demonstrated that its cost position is competitive with peer independent facilities at its volume and specialty mix.
The distinction is significant in practice. Stability inside your own reporting is not the same as competitiveness relative to the market. A facility that opened with a cost structure above market rates and has maintained that structure consistently will show no internal variance while carrying a cost per case materially higher than what comparable independent ASCs and OBLs sustain. Your reporting confirms the stability. It has no mechanism to surface the gap.
What a Meaningful Cost Per Case Benchmark Actually Requires
A meaningful benchmark for cost per case in an independent ASC or OBL requires two inputs that most facilities cannot generate internally. The first is a clear separation of procedure-driven costs from commodity supply costs within the facility’s own cost per case figure. These two components behave differently, respond to different interventions, and require different reference points to evaluate. Treating cost per case as a single figure obscures which component is driving the number and which is within the facility’s ability to address.
The second input is peer pricing data from comparable independent facilities. Specifically, invoice-level commodity supply costs from facilities running similar procedures at similar case volume. According to VMG Health’s multi-specialty ASC benchmarking data, drugs and medical supplies represent 26.3 percent of the average ASC’s operating budget, with material variance between facilities at similar volume driven by purchasing position rather than clinical differences. Published figures at this level of aggregation provide directional orientation. They do not provide a facility-specific benchmark that isolates where your commodity supply cost per case sits relative to what comparable independent facilities at your procedure mix actually pay.
As examined in prior work on supply cost as a percentage of revenue for a cardiovascular OBL, the relevant comparison for an independent procedural facility is not against a multi-specialty average but against peer independent facilities at comparable volume and specialty mix. That comparison narrows the reference population to the one that actually reflects your cost structure, and it produces a benchmark with enough specificity to reveal where the gap originates and what it amounts to per case.
The Two Components of Cost Per Case That Require Different Benchmarks
Procedure-driven costs and devices, implants, and other procedure-specific inputs, are largely determined by manufacturer contracts, clinical protocol, and the physician’s negotiating position with device representatives. These costs establish a floor for cost per case that varies by procedure type and is not primarily a purchasing position problem. Benchmarking them requires comparison against what facilities running the same procedures under comparable contract terms pay for the same clinical inputs.
Commodity supply costs per case are a different problem entirely. Drugs, contrast agents, saline, procedure packs, and general consumables run through every case regardless of procedure type. They reprice inside distributor relationships on cycles the facility does not control. And they carry the most recoverable variance in cost per case between independent facilities at similar volume and not because of clinical differences, but because of the purchasing position each facility holds relative to the market for independent operators at its scale.
A facility that benchmarks its total cost per case without separating these two components cannot determine which portion is addressable. The device cost floor is real and largely fixed within a procedure mix. Commodity supply cost position is different. For most independent physician-owned ASCs and OBLs, it has simply never been compared against what peer facilities pay.
Where the Data to Benchmark Cost Per Case Actually Lives
The data required to benchmark cost per case at the commodity supply level exists. Independent procedural facilities purchase from the same distributor networks, buy many of the same SKUs, and operate within a purchasing infrastructure that generates invoice-level pricing data across the independent facility market. The challenge is not data availability in the abstract. It is data access at the facility level.
Your distributor holds your pricing data and theirs. They have no structural incentive to show you what comparable independent facilities pay for the same inputs. Published industry benchmarks aggregate too broadly to isolate commodity supply cost per case at the specialty and volume level that would make the comparison actionable. And your own reporting, however accurate, contains only your side of the comparison.
The benchmark you are looking for is a real number. It requires access to peer pricing data from the right population of comparable independent facilities. That access has not historically been available to independent operators as a matter of course.

Frequently Asked Questions
How do I benchmark my cost per case against comparable facilities?
Benchmarking cost per case against comparable facilities requires separating your total cost per case into procedure-driven costs and commodity supply costs, then evaluating each against the appropriate peer reference point. Procedure-driven costs require comparison against facilities running the same procedures under comparable contract terms. Commodity supply costs require invoice-level pricing data from comparable independent ASCs and OBLs at your volume and specialty mix. The second comparison is the one most independent facilities have never made, and it is where the most material variance in cost per case typically resides between peer facilities.
Why is cost per case difficult to benchmark for an independent ASC or OBL?
Cost per case is difficult to benchmark for an independent ASC or OBL because the comparison requires peer pricing data that does not exist inside the facility’s own financial infrastructure. Internal reporting shows what the facility spent per case relative to its own history. It cannot show what comparable independent facilities at the same volume and procedure mix pay to produce the same cases. The peer pricing data required to close that gap exists in distributor networks and purchasing systems, but it has not historically been available to independent operators as a matter of course.
What is the difference between cost per case benchmarking and supply cost benchmarking?
Cost per case benchmarking evaluates total case-level costs, including both procedure-specific inputs and commodity supply costs, against a peer reference population. Supply cost benchmarking focuses specifically on the commodity supply layer, including drugs, contrast agents, saline, and procedure packs, and measures what the facility pays per unit for those inputs against what comparable independent facilities pay for the same SKUs. Benchmarking at the commodity level is more actionable for most independent ASCs and OBLs because it isolates the component of cost per case with the most recoverable variance between peer facilities.
How does commodity supply cost position affect cost per case in an independent facility?
Commodity supply costs run through every case regardless of procedure type and reprice inside distributor relationships on cycles the facility does not control. When a facility’s commodity supply costs run above market rates for comparable independent facilities at its volume, every case it produces costs more than it should relative to peer facilities. That per-case cost premium does not appear as a named variance in standard reporting. It accumulates across all cases over time, producing a total cost per case that looks stable internally while remaining above what comparable independent facilities sustain at the commodity level.
What data is required to benchmark cost per case in a physician-owned ASC against peer facilities?
Benchmarking cost per case in a physician-owned ASC against peer facilities requires three data inputs: the facility’s own invoice-level cost data showing what it pays per unit for its highest-volume commodity supply SKUs, equivalent invoice-level pricing from comparable independent facilities at similar case volume and procedure mix, and a framework for interpreting the comparison that separates procedure-driven costs from commodity supply costs. Your own invoice-level cost data exists inside the facility. Access to peer pricing data requires a source outside your operation. Converting that comparison into something actionable rather than directional requires the analytical infrastructure to separate procedure-driven costs from commodity supply costs at the line-item level.
