Your hospital is paying rent on cylinders it already returned.
We reconcile twelve months of medical gas invoices against your supply agreement, document every discrepancy to its source line, and hand you the claim.
No recovery, no fee. The first review is free.

Where medical gas spend leaks
Four places the money goes, and the three-step cycle that gets it back and keeps it from going again.
The three services map to the cycle: the recovery review identifies, the claim recovers, and monthly reconciliation prevents the same money leaking again next year.
Services
Three ways we work, in the order they usually happen. Each one stands alone.
Medical gas recovery review
Twelve months of invoices reconciled against your supply agreement. You receive a findings report with every discrepancy traced to its source line and the contract clause it breaches.
Rate benchmark
Your pricing set against comparable facilities. Where you are above market, we give you a repricing target and the specific contract language to open the conversation.
Cylinder reconciliation
A monthly physical count against rental billing, on site. Demurrage stops accruing on cylinders you no longer hold, so the same money does not leak again next year.
What we look for
Every category below is provable from documents you already hold. None of it requires clinical judgment or access to patient data.
- Cylinder demurrage
- Daily rental accruing on cylinders sitting in storage rooms, on docks, and in hallways, long after they stopped being used.
- Lost cylinder charges
- Billed per cylinder, routinely, and often for cylinders that came back but were never credited to the account.
- Contract rate versus billed rate
- Line items priced at list when a negotiated rate sits in the agreement. The most common finding, and the easiest to prove.
- Escalator misapplication
- Annual increases run against the wrong base year, applied twice, or applied to items the contract excludes.
- Unsupported surcharges
- Fuel, hazmat, delivery, and small-order minimums appearing with no basis anywhere in the agreement.
- Tank and telemetry billing
- Bulk equipment rental continuing after the tank was removed, replaced, or downsized.
- Duplicate deliveries
- Standing orders that kept running after demand dropped, delivered and billed twice in the same cycle.
How an engagement runs
Three steps. You commit nothing until you have seen what we found.
-
Send the documents
Twelve months of invoices and your current supply agreement. Nothing else, and no system access.
-
We reconcile
Every line against every clause. You receive a findings report with each discrepancy traced to its source and the contract term it breaches.
-
You claim, we support
You take the findings to your supplier. We supply the backup. We invoice only after credits reach your account.
What it costs
Nothing, unless we find money. Rates step down as the recovery grows.
| First $25,000 recovered | Medical gas recovery review | 40% |
|---|---|---|
| $25,000 – $100,000 | 30% | |
| Above $100,000 | 20% | |
| Rate benchmark | Capped per engagement, agreed before we start | 25% of year-one savings |
| Cylinder reconciliation | Monthly, minimum $500 | $4–6 per bed |
What we need from you
Four items. Most supply chain offices can pull them in an afternoon.
- Twelve months of medical gas invoices
- The current supply agreement, including amendments
- The cylinder rental and demurrage schedule
- Delivery tickets, if your team keeps them
Insights
How medical gas billing actually works, and where it goes wrong.
How cylinder rent accrues on gas you already used
Demurrage is charged on possession, not consumption. Understanding that distinction is where most of the recoverable money sits.

Rental schedules, escalator clauses, telemetry fees and surcharge provisions — what each one actually commits you to.
Read the articleWhy annual increases are so often applied wrong
Wrong base year, double application, and increases applied to line items the agreement excludes. All three are common and all three are provable.

Northmark Recovery reviews hospital medical gas billing. That is the whole practice — one category, examined properly, rather than a broad sweep that skims it.
Medical gas rarely gets audited. It is too small to justify a dedicated analyst inside a hospital and too specialised for general accounts payable review. Invoices arrive, get matched to a purchase order, and get paid. The contract they were supposed to be checked against sits in a drawer.
We are independent of every supplier. Suppliers do run their own cylinder audits, and those audits are useful — but a supplier reviewing its own billing will not surface a rate discrepancy, a misapplied escalator, or a surcharge with no contractual basis, because each of those errors runs in its favour.
We take no title, hold no product, and arrange no supply. We read documents and report what they say.
We work one category at a time, properly. Medical gas is where we start with most clients.
