The 6-12% gap between billing and collections that most clinics ignore

$300K to $600K per year

This post is about the 6–12% gap and the 5 places it hides. If your billing team says everything is fine, start with billing-team-says-everything-is-fine.

Based on the practices we have reviewed, at a $5M multi-location clinic, 6-12% of revenue disappears between what gets billed and what actually hits the bank account.

That is $300K to $600K per year.

Not lost to bad debt. Not lost to low patient volume. Lost in the space between billing a claim and collecting the cash. Lost in timing gaps, process failures, and numbers that nobody reconciles.

If you run a single-location practice doing $1.5M, the math still hurts: $90K to $180K per year. Enough to fund a full-time provider. Enough to change your take-home pay dramatically.

Where does all that money go?

The five places money disappears

We have audited dozens of clinic revenue cycles. The same five leaks show up every time, in roughly the same order of magnitude.

1. Slow claim submission

The clock starts ticking the moment a patient walks out of your office. Every day between the date of service and the date the claim is submitted is a day your cash is delayed. But delay is not the only problem.

Some claims never get submitted at all. They get stuck in a coding queue. The provider did not finish the note. The front desk entered the insurance wrong. The claim needs a modifier that nobody added. It sits in a "hold" bucket in the billing system.

We see clinics with 5-15 days of average lag between date of service and claim submission. At high-volume practices, that represents tens of thousands of dollars in claims that have not even entered the payment pipeline.

2. Incorrect contractual adjustments

When a payer sends a payment, the difference between your billed charge and the allowed amount gets written off as a contractual adjustment. This is normal. Your fee schedule says $200, the contract says the payer pays $140, you write off $60.

The problem is when the adjustment is wrong. The payer sends $120 instead of $140, and the adjustment is automatically posted as $80. Nobody checks whether that $120 matched the contracted rate. The billing system accepts the payment, posts the adjustment, and moves on.

Across hundreds of claims per month, incorrect adjustments add up fast. We routinely find $2K-$8K per month in underpayments that were accepted without question at a single location. Across multiple locations, it compounds.

3. Denied claims that die in a pile

I wrote about this in detail in my previous post on denied claims. The short version: industry data suggests up to 65% of denied claims are never resubmitted. At a $5M practice with a 10% denial rate, that is $325K in claims that were denied and abandoned.

The denial itself is not always the problem. The problem is the absence of a process to work denials systematically. Claims get denied, they sit in a queue, they age past timely filing limits, and the revenue is gone.

4. Underpayments nobody catches

This is different from incorrect contractual adjustments. Underpayments happen when a payer simply pays less than the contracted rate, and nobody notices.

Your contract with a payer says they will pay $185 for a specific CPT code. They send $160. The payment gets posted. The balance gets adjusted. Nobody compares the payment to the fee schedule.

To catch underpayments, you need two things: access to your payer contracts with the actual fee schedules, and a process for comparing payments against those schedules. Most clinics have the contracts filed away somewhere but have never built the comparison into their billing workflow.

We find underpayments in every practice we audit. The amounts vary, but $3K-$10K per month per location is common for mid-size clinics.

5. Missed charges

Services rendered but never billed. This is the leak that surprises clinic owners the most because it happens before the billing process even starts.

A provider does a procedure but does not document it in the note. A front desk staff member checks in the patient but does not capture the correct service. A lab is performed but the order is not linked to a billable encounter.

Missed charges are hardest to quantify because there is no record of what was never billed. But when we compare provider schedules and patient encounter data against claims submitted, the gaps become visible. In some practices, we find 2-5% of encounters have missing or incomplete charges.

At a practice seeing 200 patients per day across three locations, even a 2% miss rate is 4 encounters per day. If the average encounter value is $150, that is $600 per day, $156K per year.

Why most clinic owners never see it

The problem is structural. Your practice operates with two separate financial views, and nobody puts them together.

View 1: The billing company. They see claims, payments, denials, and adjustments. They report a collection rate based on their data. That rate typically looks good because of how it is calculated. Many billing companies use "adjusted collection rate," which removes denials and contractual adjustments from the denominator. By that math, you can have serious revenue leaks and still show a 95% collection rate.

View 2: The accountant. They see bank deposits, expenses, and profit. They reconcile your books against your bank statements. They have no visibility into what was billed, what was denied, what was underpaid, or what was never billed in the first place.

Neither view is wrong. But neither view is complete. The gap between them is where revenue disappears.

How to measure it

The measurement is straightforward, but almost nobody does it.

Step 1. Pull total charges from your billing system for a given month. This is everything that was billed.

Step 2. Pull total collections (payments received) from your billing system for the same period. Remember that collections for a given month include payments on claims from previous months.

Step 3. Pull total bank deposits for that month. Separate out non-patient-revenue deposits (loans, grants, owner contributions).

Step 4. Compare billing collections to bank deposits. They should match closely. If billing says you collected $400K but your bank shows $370K in patient-revenue deposits, you have a $30K gap to investigate.

Step 5. Break it down by payer. Which payers have the largest gap between expected and actual payments? Break it down by location. Which locations have the worst collection performance?

This is what a location-level P&L with billing data integration looks like. It is the single most useful financial report a multi-location clinic can have, and almost none of them have it.

What good looks like

Collection rates vary by specialty, but here are the benchmarks we use when evaluating a practice.

These are net collection rates, meaning total payments received divided by total allowed amounts (charges minus contractual adjustments). This is the number that matters, not the adjusted rate your billing company reports.

If your practice is below the "average" range for your specialty, you are almost certainly losing significant revenue to one or more of the five leaks above. If you are in the "good" range, there may still be room to recover $50K-$100K per year depending on your volume.

Where we start

If you have never reconciled your billing data with your bank deposits across all your locations, that is where we start.

We do exactly this for our clients. We pull billing data, bank statements, and payer contracts. We map where money falls out at every stage. Not your billing company's version. Not your accountant's version. The full picture.
