When you compare clearinghouses, the first number you see is the per-transaction rate. It is also the most misleading number in the conversation.
Legacy clearinghouses quote four or five cents per transaction. It sounds cheap. It is meant to. What that number hides is the operational reality of how transactions actually work behind a single patient visit, and the way that reality compounds at scale.
Here is what the per-transaction rate is actually charging for, and how to calculate the number that matters instead.
What a Transaction Actually Means
A transaction in clearinghouse pricing is a single EDI exchange. Every request-and-response cycle counts. A per-transaction rate applies to each of them independently.
For a single patient visit, the transactions that fire between your practice and the payer typically include:
- Eligibility verification (X12 270 request, X12 271 response), usually one at scheduling, often another at check-in for patients with volatile coverage
- Claim submission (X12 837)
- Claim status inquiry (X12 276 request, X12 277 response), often more than one over the life of the claim
- Electronic remittance advice (X12 835), the payment posting
For a single, clean, straightforward patient visit, that is at least four billable events. If the eligibility check runs twice, if claim status is checked more than once, or if the claim gets denied and resubmitted, the count climbs.
The Math That Matters
Take the industry’s typical per-transaction rate. Four to five cents per transaction, quoted as the marquee number in most sales conversations.
Multiply by the four transactions a typical clean patient visit generates. That is 16 to 20 cents per patient, before any resubmissions, additional eligibility rechecks, or denial-driven activity.
Now consider a mid-sized practice submitting 800 claims per month. At 20 cents per patient (the low end of the true cost calculation), that is $160 per month, $1,920 per year. At more realistic transaction counts, five to six per patient once you account for eligibility recheck, multiple status inquiries, and typical denial rates, the true cost lands closer to 25 to 30 cents per patient. Same practice, that is $200 to $240 per month, $2,400 to $2,880 per year.
The per-transaction rate looked cheap. The per-patient cost tells the truth.
Why This Compounds As You Scale
The per-transaction model has a specific problem that gets worse as your volume grows.
- Every increase in patient volume increases transaction count more than proportionally
- Every increase in denial rate compounds transaction volume through resubmissions
- Every additional eligibility recheck adds cost, and coverage volatility is up across the industry
- Every payer that tightens its adjudication and forces additional status inquiries adds cost
- Every claim that requires reformatting and resubmission adds cost
The mid-sized practice paying $2,880 a year at 800 claims per month scales to $7,200 at 2,000 claims per month, and higher again if denial activity climbs. These numbers move in one direction over time. As the industry’s underlying denial rates rise, transaction counts per patient rise with them.
How to Actually Compare Vendors
Before signing with any clearinghouse, insist on the answer to one question: what is the fully loaded cost per patient, including every transaction type this vendor will bill me for?
A vendor whose pricing is genuinely competitive per patient will be happy to walk you through the math on your specific volume and payer mix. A vendor whose pricing looks competitive per transaction but expensive per patient will resist the calculation, or will hedge with volume tiers, minimum commitments, and add-on fees.
A few specific things to ask:
- What transaction types are billable, and at what rate? Some vendors bill 837 submission at one rate and 835 ERA at another, which further inflates per-patient totals.
- Is eligibility verification included, or billed separately? For practices that verify pre-visit and again at check-in, eligibility can be a meaningful chunk of the total.
- Is claim status included, or billed separately?
- What is the vendor’s average transactions-per-patient ratio across their customer base?
- What happens to your total cost if your denial rate climbs two percentage points?
The answers should be specific and quantified. If they are not, that is information too.
How Harris Secure Connect Prices Differently
Harris Secure Connect charges once per patient. Not per transaction. Eligibility verification, claim submission, claim status inquiry, ERA processing, and Claims Correct AI scrubbing are all included in the same per-patient rate.
For practices comparing HSC to a per-transaction legacy vendor, the difference is significant on day one and widens as your volume grows. There are no separate line items for eligibility. No additional charge for claim status. No surprise ERA processing fees. One patient, one charge, every transaction type included.
If you have been quoted a per-transaction rate by another vendor and want to know what the true cost per patient would look like on your specific volume, our team is happy to run that math against what you are paying today. No pressure, just a clearer picture of what the number actually is.
