Still Calculating Your Per-Case Profitability on Paper? Let AI do the Heavy Lifting

Ask most surgery centers what a case cost, and someone opens a spreadsheet.

The numbers exist. Item prices are in the materials system. What the surgeon actually likes to have opened is on a preference card — often a printed one with pen marks on it. The reimbursement rate is in a fee schedule. Case details are in the EHR.

Getting all of that into one number per case is the hard part, and it is almost always done by hand.

What manual case costing actually looks like

A typical pass takes twenty minutes or more per case:

• Pull the marked card and read the handwriting
• Look up each item's current price in the inventory system
• Add implants, and hunt down the lot and serial numbers
• Estimate staff time and apply a rate
• Find the CPT reimbursement rate
• Subtract, then copy the result into a workbook

Do that for a full schedule and it is a week of work. Most centers do it for a sample of cases, once a quarter, and treat the answer as directional. By then the schedule that created the problem is long gone.

Finch syncs the inputs so the math is already done

The work above is not analysis. It is data entry. That is the part software should own.

Your item catalog and prices. Finch imports your catalog from your materials system, cleans up the vendor naming so items are actually searchable, and keeps unit prices in sync. When a vendor price changes, the next case costs at the new price without anyone retyping it.

Your preference cards. Upload an existing card as a PDF, a Word doc, or pasted text. Finch reads the lines and matches each one to an item in your catalog, so you are not rebuilding cards by hand. Cards are versioned, so you can see what changed and when.

Your case data. If your cards and schedule live in your EHR or scheduling system, they can stay there. Upload the marked card or paste the case rows, and Finch maps them to catalog items and prices for you.

What was actually used. Staff mark used versus pulled during the case, including substitutions and anything opened mid-procedure. That is the difference between what the card says a case costs and what it really cost.

Reimbursement. Finch looks up the Medicare ASC rate for each CPT on the case from the CMS fee schedule. Apply your own multiplier for commercial payers, or enter the actual revenue if you already know it.

Then you review a number instead of building one

Once the inputs are connected, the case closes and the margin is there: cost broken out by supplies, implants, and labor; revenue; gross and net profit; margin percentage; and revenue and profit per OR hour.

Finch also writes the read-out — a plain-language summary of where the money went, which line items moved the margin, and what looks like a risk. You can export it as a PDF and hand it to a board or a surgeon without reformatting anything.

One of our centers went from roughly twenty minutes of case costing to about one minute per case. The math did not get easier. It stopped being done by a person.

Forecast now, actuals later

The estimate at case close is a forecast. When the EOB posts, record what actually came in and what it actually cost. Finch keeps both and shows you the variance.

That is the loop that makes per-case margin trustworthy: you find out where your estimate was wrong, and the estimate gets better.

Questions you can ask once every case is costed

The point of costing every case instead of a sample is that patterns become visible:

• Which procedures lose money at a specific payer's rate
• Which surgeons' cards cost more than their peers' for the same procedure
• Which items show up on cards but rarely get used
• How margin per OR hour compares across your centers

You can ask those in plain English. Finch answers from your own case data, not an industry benchmark.

The real cost of doing it on paper

Manual case costing is not just slow. It quietly limits the decisions you are willing to make.

You do not renegotiate a contract on a sample of six cases. You do not tell a surgeon their card is expensive when your best evidence is a spreadsheet from last quarter. You do not drop a procedure without confident numbers.

When every case is costed automatically, those conversations become routine.

If your team is still rebuilding a workbook every month, the bottleneck is not effort. Schedule a walkthrough and we will cost a few of your real cases with you.
