The “Cost of Waiting”: How Denials Are Draining Your Practice’s Lifeline

Claim denials are not an administrative inconvenience with a financial side effect.
They are a financial problem that happens to arrive in administrative clothing, and
the industry data for 2025 makes the size of it hard to argue with.

The numbers

In 2025, healthcare provider organisations lost an estimated $48.4 billion
in net revenue to final denials and uncollected patient balances — a
25% increase in net revenue leakage on the previous year. That
analysis covers 2025 performance across more than 2,300 hospitals on the Kodiak
platform, so it is not a vendor’s extrapolation from a handful of accounts.

Contesting those claims is not free either. Providers spend close to
$19.7 billion a year on the administrative cost of fighting denied
claims, at an average of $43.84 to rework a single denial. Read
those two figures together and the shape of the problem is clear: you lose the
revenue, and then you pay for the privilege of trying to get it back.

Underlying denial rates have been climbing for years — around 12% in 2023, up from
9% in 2016 — and front-end issues, particularly registration and eligibility errors,
remain a leading cause. That last detail matters more than it sounds. Front-end
denials are the avoidable ones. They are caused before the clinical work is even
billed, which means they are also the cheapest ones to stop.

Why “we’ll deal with it next quarter” is a decision, not a delay

Denials have a clock on them. Appeal windows close. Timely filing limits expire. And
the probability of collecting an account falls with its age — past around 40 days in
A/R the odds start deteriorating quickly, and they never recover.

So deferring the problem is not neutral. Every month you leave a 12% denial rate in
place is a month of claims aging toward the point where working them stops being
worth the labour — which is the moment a denial quietly becomes a write-off, without
anyone deciding to write it off.

There is a non-financial cost too, and practices tend to underweight it because it
does not appear on a report. It is the hours your team spends on payer disputes
instead of patients, and the burnout that follows from a job that is mostly
rework.

What we do about it

RevAmp offers performance-based revenue cycle management: we are paid a percentage of
what we actually collect, above a threshold agreed in advance. The consequence that
matters to you is that we absorb the cost of denials and rework. If
a claim has to be corrected, appealed and resubmitted, that is our labour and our
expense — there is no rework line on your invoice, and no incentive on our side to
send a claim that isn’t clean in the first place.

You also get a named, US-based account manager. Not a ticket queue, not an offshore
team you cannot identify — a person who knows your payer mix and whose number you
have. When something goes wrong, the delay in fixing it is usually a communication
delay, and that is the one thing an anonymous call centre guarantees.

The number on your own claims

None of the above tells you what your denials cost, and an industry average
is a poor substitute for your figures. The
billing savings calculator models it on your
own claim volume, average claim value and rejection rate. It is not behind a form,
it does not ask for an email, and nothing you type is stored.

If the number is uncomfortable, the next step is a free A/R audit: send an aging
report and a superbill, and we come back with where the money is sitting, which
payers are slowest, and which denial reasons keep repeating. You keep the analysis
whether or not you hire us.
