Should You Switch Billing Companies if Your Family Practice Denial Backlog Keeps Growing?

A growing denial backlog is more than a billing department problem. For a Family Practice, it can mean delayed payments, increasing A/R, more staff time spent on rework, and revenue that becomes harder to recover as claims age.

But a large denial backlog does not automatically mean you should switch billing companies.

The better question is: Is your current billing company actually fixing the causes of denials, or is it simply working through the same problems every month?

That distinction matters. The American Academy of Family Physicians (AAFP) recommends tracking denial rate alongside days in A/R and adjusted collection rate because these measures provide a clearer picture of revenue cycle performance. A practice can have acceptable overall A/R while still carrying a significant amount of older receivables.

When Does a Denial Backlog Become a Serious Problem?

Not every denial needs to be treated as a crisis.

Some claims may require additional documentation, payer review, corrected claims, or a formal appeal. The concern begins when the backlog keeps increasing despite having an established billing process.

For example, your Family Practice may notice that:

Denials from previous months are still open.

The same denial reasons continue appearing.

High-dollar claims are sitting without timely follow-up.

Appeals are being submitted, but the practice does not know their outcomes.

The billing company provides a number of claims worked but cannot show how much revenue was recovered.

The denial rate is not improving even after repeated discussions.

A/R over 90 or 120 days continues to increase.

These are operational warning signs because the issue is no longer simply the number of denied claims. It is whether the denial process is producing financial results.

AAFP specifically recommends monitoring older A/R because a reasonable overall A/R number can hide a significant amount of receivables that are more than 90 or 120 days old.

A Growing Backlog Does Not Always Mean the Billing Company Is the Problem

Before terminating a billing relationship, a Family Practice should determine where the problem is actually coming from.

Some denials originate before the claim reaches the billing team. Registration errors, incorrect insurance information, authorization problems, missing documentation, coding issues, and charge-entry mistakes can all contribute to payment problems.

AAFP notes that identifying and correcting mistakes before claim submission can help reduce denials and improve cash flow.

This is why simply asking your billing company to “work denials faster” may not solve the problem.

If the same eligibility, authorization, coding, or documentation issue keeps creating new denials, the backlog can continue growing even when staff are actively working accounts.

The real question is whether your billing company is identifying those patterns and communicating them back to the practice.

Ask Why the Denials Are Happening

A good denial review should go beyond counting claims.

Your Family Practice should be able to see denial trends by payer, reason, provider, CPT or service type, dollar value, and aging.

Suppose a practice has 500 open denials. That number alone does not tell leadership much.

But if 180 of those denials are related to one recurring payer issue, 100 involve authorization problems, and another group involves coding or documentation, the next step becomes much clearer.

The billing company should be able to explain:

What caused the denial?

How many claims are affected?

What is the total dollar value?

Which payer is responsible?

How old are the claims?

What action has been taken?

How many have been recovered?

How many remain appealable?

What is being done to prevent the same denial from happening again?

Without this information, a denial report can become a productivity report instead of a revenue report.

The Biggest Warning Sign: The Same Denials Keep Coming Back

A denial management process should not only recover individual claims. It should help reduce recurring problems.

For example, if a Family Practice repeatedly receives denials because of missing authorization, the billing company should identify the pattern and communicate it to the appropriate front-end or clinical team.

If claims are repeatedly denied because of coding or documentation issues, the practice should receive specific feedback.

If a payer repeatedly underpays or denies a particular service, the practice should be able to identify the pattern through payer-level reporting.

This is where denial management becomes part of revenue cycle improvement rather than simply claim follow-up.

AAFP describes denial rate as a measure of revenue cycle effectiveness and notes that practices should establish processes to identify errors before claims are submitted.

Are Your High-Dollar Denials Being Prioritized?

Another question to ask is whether your billing company treats every denial equally.

A $50 denial and a $5,000 denial should not necessarily receive the same priority.

Family Practices should understand how their billing partner prioritizes accounts based on factors such as dollar value, filing deadlines, payer requirements, denial reason, and likelihood of recovery.

This becomes particularly important when the backlog is large.

If the billing team is spending significant time on low-value claims while high-dollar accounts continue aging, the practice may be losing more revenue than the denial count suggests.

What About Appeals?

Appeals are another area where a growing backlog can expose weaknesses.

A billing company should know which claims require corrected submission, reconsideration, medical documentation, payer-specific appeal procedures, or other action.

For Medicare fee-for-service claims, CMS provides a defined appeals process, including redetermination and subsequent levels of review. CMS currently states that a first-level Medicare redetermination generally must be requested within 120 days from receipt of the initial determination.

That makes timely tracking important.

A claim should not sit in a general denial queue until its appeal opportunity becomes more difficult or expires.

Your billing company should have a process for identifying filing and appeal deadlines and escalating accounts that require practice documentation.

Six Questions to Ask Your Current Billing Company

Before deciding to switch vendors, ask for clear answers to six questions.

1. What are our top five denial reasons by dollar value?

This tells you whether the company understands the financial causes behind the backlog.

2. Which payers are creating the most denials?

A payer-level view can reveal problems that are hidden inside an overall denial percentage.

3. How much denied revenue has been recovered in the last 90 days?

The number of accounts worked does not tell you how much money actually came back to the practice.

4. How much of our denial A/R is over 90 and 120 days?

Older A/R deserves separate attention because overall A/R can hide aging problems.

5. Which recurring denial causes have been corrected at the source?

This separates true denial management from repeated claim follow-up.

6. What is your plan for reducing the backlog over the next 30, 60, and 90 days?

You should receive measurable targets rather than a general promise to “work harder.”

When Should a Family Practice Consider Switching Billing Companies?

A switch may deserve serious consideration when the problem is persistent and the billing company cannot demonstrate a credible improvement plan.

For example, if the denial backlog continues growing, recurring denial causes remain unresolved, high-value claims are aging, reporting lacks useful detail, and leadership cannot clearly see recovered revenue, the practice has reasonable grounds to reassess the relationship.

The issue is not whether a vendor has ever had denials.

Every medical practice will encounter claims that require correction, additional information, reconsideration, or appeal.

The more important issue is whether the vendor has a repeatable process for identifying, prioritizing, resolving, and preventing those denials.

Before You Switch, Compare In-House and Outsourced Denial Management

Changing billing companies is a major operational decision. It can affect claim workflows, staff responsibilities, payer communication, reporting, and the transition of existing A/R.

Before making the change, compare the actual performance of your current operation with what an alternative billing model would provide.

Look at staffing, specialty experience, denial expertise, reporting, payer follow-up, appeal management, technology, escalation procedures, and accountability.

A useful comparison is what your Family Practice is paying for denial management versus the revenue currently being recovered and the A/R that remains unresolved.

For a deeper comparison of the two models, see In-House vs. Outsourced Family Practice Denial Management.

What a Strong Family Practice Billing Partner Should Show You

A billing partner should be able to connect denial activity with financial outcomes.

That means reporting should help practice leadership understand denial rate, denial dollars, A/R aging, payer performance, recovery results, recurring denial causes, and unresolved high-value accounts.

It should also connect front-end problems with back-end consequences.

For example, if authorization issues are producing repeated denials, the answer may require a workflow change before the claim is submitted. If coding-related denials are recurring, the practice may need targeted coding review or provider education.

The goal is not simply to make the denial queue smaller.

The goal is to make the revenue cycle more predictable.

The Bottom Line

A growing Family Practice denial backlog is a reason to investigate your billing operation—not an automatic reason to change vendors.

Start with the data.

Look at denial rate, denial dollars, payer patterns, A/R aging, recovery rate, recurring denial reasons, and the age of unresolved claims. Then ask whether your billing company can explain the problems and show what is being done to prevent them.

If the backlog is growing while the same denial causes continue to appear, high-value claims are aging, and there is no measurable improvement plan, it may be time to evaluate whether your current billing arrangement is still meeting the needs of your practice.

Medical Billers and Coders (MBC) provides medical billing and revenue cycle support for physician practices, including denial management, claims follow-up, coding support, and A/R management. The focus should be on more than processing claims—it should be on understanding where revenue is getting delayed or lost and building a process to address those problems.
