Denial Rate Benchmarks

Denial rate is the share of claims a payer denies on first submission. Industry surveys put the typical initial denial rate in the 5–15% range, with a widely cited 'best practice' target under 5%. The number practices should care about more is the recovery gap: a large share of denials are appealable, but industry data consistently shows most are never reworked. The ranges below are directional and vary by specialty and payer mix.

Band	Initial denial rate	What it means
Best practice	Under 5%	Strong front-end and clean submissions; keep it here
Typical / industry average	~5–10%	Normal range; the leverage is in reworking what's denied
Elevated	~10–15%	Front-end or payer-policy issues worth investigating
High	Above 15%	Systemic problem — eligibility, coding, auth, or a payer edit
— Rework reality —	~60%+ of denials are never reworked	Most denied dollars are winnable but abandoned
— Overturn reality —	A large share of appealed denials are overturned	The money sits in the pile no one has time to work

What to do with this

A rising denial rate is a symptom — trace it to a cause (eligibility, prior auth, coding, timely filing, a specific payer edit) rather than treating the rate itself.
The bigger dollar leak usually isn't the denial rate — it's the rework rate. Denials that are never appealed are pure lost revenue on services you already delivered.
Segment denials by CARC group and by payer; a few root causes and one or two payers typically drive most of the volume.
Distinguish 'soft' denials (fixable and resubmittable) from 'hard' denials (need a true appeal) so you spend effort where it pays.

The industry statistic that matters most here is that most denials are never reworked. Volari exists to close that gap — it works the appealable pile end-to-end, so denied claims get recovered instead of written off for lack of hours.
