Denial Management vs Denial Prevention
Is it better to prevent denials or get better at appealing them?
Short answer
These are usually presented as alternatives and are actually a sequence. The order is determined by cash, not philosophy.
Prevention has the better unit economics and no upper bound on how much it helps, but it only affects claims not yet submitted. If you have 90 days of denied claims sitting unworked, prevention returns nothing on them, and every week that passes moves some of them past appeal deadlines permanently.
So: work the backlog to recover what is still recoverable, and build prevention in parallel so the backlog does not rebuild. Running only the first is a treadmill. Running only the second concedes revenue that was collectible.
Side by side
Denial prevention vs Denial management
| Dimension | Denial prevention | Denial management |
|---|---|---|
| Acts on | Claims not yet submitted | Claims already denied |
| Cost per claim addressed | Minutes of front-end work | $57.23 average to contest (Premier, 2023) |
| Recovers existing lost revenue | No | Yes |
| Ceiling on impact | 84% of denials are potentially avoidable (Optum) | ~70% of appealed denials are overturned |
| Time to visible result | 30–60 days as new claims cycle | Immediate as appeals resolve |
| Main levers | Eligibility, authorization, scrubbing, coding review | CARC/RARC triage, appeal letters, payer escalation |
| Fails when | Front desk is undertrained or understaffed | Appeal deadlines pass unworked |
| Compounds over time | Yes | No — it is remedial by nature |
Prioritise prevention when
- Denials cluster on eligibility, registration or authorization — the categories that should never happen.
- Your appeal backlog is already current.
- The same CARC appears repeatedly across the same payer.
- You are adding volume and want the denial count not to scale with it.
Prioritise management when
- You have unworked denials approaching appeal deadlines.
- AR beyond 90 days is a material share of total AR.
- Denials are being written off as contractual adjustments rather than appealed.
- Cash flow needs to improve inside a quarter.
When this is not the right answer
One qualifier on the widely quoted prevention numbers: the 84% avoidability figure comes from hospital claim remits, not physician practices, and the mix differs. The direction is sound and the order of magnitude is right, but a solo practice should not expect hospital-scale denial economics to map exactly onto its own.
Questions
Optum's Revenue Cycle Denials Index puts 84% of denials as potentially avoidable, based on roughly 124 million hospital claim remits across more than 1,400 US hospitals. The widely circulated '90% of denials are preventable' figure traces to a 2014 blog post with no published methodology and is best avoided.
Commercial payers commonly allow 90 to 180 days from the remittance date, varying by payer and contract. Medicare provides five appeal levels, the first being redetermination within 120 days of the initial determination. Secondary claims often carry shorter windows, which is where deadlines are most often missed.
