Denial Management Services: What to Outsource and What to Keep
Denial management services work best when you split the work: outsource rework and appeals volume, keep root-cause fixes and payer strategy in-house.
Denial management services make the most sense when you split the work. Outsource the volume: sorting denials, correcting and resubmitting claims, and preparing and tracking appeals. Keep the decisions in-house: documentation standards, coding policy, payer strategy and write-off approval. Then hold the vendor accountable for one thing above all, which is fixing causes so fewer denials come back next month.
Why denials keep climbing
Denials are getting harder to manage, not easier. In Experian Health's 2025 State of Claims survey of 250 healthcare professionals:
- 41% said their denial rate is 10% or higher, a share that has grown every year since 2022.
- 68% said submitting clean claims is harder than a year ago.
- 43% said they're understaffed.
- The top causes were missing or incorrect data (50%), authorizations (35%) and incomplete or incorrect registration data (32%).
MGMA found something similar from the practice side: in a March 2024 poll, 60% of medical group leaders reported higher denial rates than a year earlier, and only 11% had reduced them.
Look at that list of causes again. Most of them start at the front desk, not in the billing office. That shapes what you should outsource.
What denial management services typically include
A full-service vendor usually covers some or all of these:
- Intake and triage. Pull denials from remittances (835s) and payer portals, then categorize by reason code, payer, provider and dollar value.
- Correction and resubmission. Fix demographic, eligibility, coding and modifier errors and send corrected claims.
- Appeals. Build appeal packets with records and letters, submit, and follow up until there's a decision.
- Payer follow-up. Call or use portals for claims with no response.
- Reporting. Denial trends by cause, payer and provider, with dollars at stake.
- Prevention. Eligibility verification and prior authorizations before the visit, where the vendor also handles front-end work.
What to outsource and what to keep
| Task | Outsource? | Why |
|---|---|---|
| Sorting and categorizing denials | Yes | High volume, rules-based, easy to measure |
| Correcting demographic and eligibility errors | Yes | Repetitive work with clear fixes |
| Payer calls and portal follow-up | Yes | Time-consuming; benefits from dedicated staff and long hold-time tolerance |
| Appeal packet assembly and tracking | Yes | Process-heavy; deadlines are easy to miss in-house |
| Eligibility checks and prior authorizations | Usually yes | These prevent the most common denial causes |
| Coding corrections on clinical documentation | Shared | Vendor flags; your coder or provider decides |
| Medical necessity appeals needing provider input | Shared | Vendor drafts; provider supplies the clinical argument |
| Documentation standards and provider education | Keep | Requires authority over providers |
| Payer contract negotiation | Keep | Business strategy |
| Write-off approval | Keep | Financial control should stay with the practice |
The pattern is simple. Outsource work that follows rules and depends on persistence. Keep work that needs clinical judgment or authority over your own people.
The work that recovers the most money
Most practices start with appeals because that's where the visible backlog sits. In our experience, the bigger return comes earlier:
- Front-end prevention. Eligibility verification and prior authorizations handled before the visit remove a large share of denials before they exist. If authorizations cause most of your denials, our guide to prior authorization outsourcing covers that piece.
- Fast turnaround. A denial worked within days is easier to fix than one found at 90 days. Records are fresh and deadlines aren't close.
- Deadline tracking. Missed appeal windows turn recoverable claims into write-offs. For Medicare fee-for-service, CMS allows 120 days from receipt of the initial determination to request a redetermination, and decisions generally come within 60 days. Commercial payers set their own windows, often shorter, so track them per payer.
- Root-cause reporting. Every month, the vendor should tell you which three causes cost the most and what changed upstream to stop them.
How to evaluate a denial management vendor
Ask these questions before you sign:
- Which systems will you work in? The vendor should work inside your practice management system and clearinghouse, not in spreadsheets they export.
- Who does the work? Dedicated staff who learn your payers and providers perform better than a shared pool.
- How do you prioritize? By dollar value and deadline, not by the order denials arrive.
- What do you report, and how often? Ask for a sample report.
- How are you paid? Percentage-of-collections, per-claim and dedicated-FTE models create different incentives. A percentage model can push a vendor toward easy, high-dollar claims and away from small ones that still add up.
- What happens at day 30? Agree on the baseline and the metrics before the vendor starts.
Ask for a short pilot. Thirty days on a defined denial backlog, measured in dollars recovered, tells you more than any proposal.
Metrics to track every month
| Metric | What it tells you |
|---|---|
| Initial denial rate | Whether front-end fixes are working |
| Denials by top 5 causes | Where to focus prevention |
| Days from denial to resubmission | Vendor speed |
| Appeal overturn rate | Quality of appeal packets |
| Dollars recovered | Program value against its cost |
| Write-offs due to timely filing | Deadline discipline. This number should trend toward zero |
Use 90 days of history as a baseline. Without one, you can't tell whether the vendor improved anything.
When outsourcing denials doesn't make sense
Outsourcing isn't always the answer. If your denial volume is small and one experienced biller keeps it under control, adding a vendor adds coordination without much return. If your denials come mainly from documentation gaps, you need provider education first, and no vendor can fix that from outside. And if your practice management system can't give a vendor secure, role-based access, solve that before you add anyone.
Key takeaways
- Most denial causes start at the front end: data, registration and authorizations.
- Outsource rules-based, high-volume work: triage, corrections, payer follow-up and appeals tracking.
- Keep clinical judgment, payer strategy and write-off approval in-house.
- Prevention and speed recover more money than working old appeals.
- Set a 90-day baseline and measure the vendor in dollars recovered.

Frequently asked questions
What do denial management services include?
Typically denial intake and categorization, claim correction and resubmission, appeals preparation and follow-up, and reporting on denial causes by payer, provider and code. Some vendors also handle front-end fixes such as eligibility checks and prior authorizations.
What should a practice keep in-house when it outsources denials?
Clinical documentation decisions, coding policy, payer contract strategy and final sign-off on write-offs. Those require provider input and business judgment the practice should own.
How long do I have to appeal a Medicare denial?
For Medicare fee-for-service, a redetermination request must be filed within 120 days of receiving the initial determination. Commercial payer deadlines vary by contract, so track them per payer.
How do I know if a denial management vendor is working?
Track denial rate, overturn rate on appeals, days from denial to resubmission, and dollars recovered per month. Compare against a 90-day baseline taken before the vendor starts.
