Why is your A/R growing while collections look fine?

The money deposited this month often comes from work performed weeks or months ago.

Older claims finally get paid. Patient balances from prior visits come in. A payer releases a group of delayed claims. All of that can make the current month look healthy.

At the same time, new claims are entering the revenue cycle every day.

Some move quickly.

Others get denied, stall with the payer, sit waiting for information, or remain open without a clear next step.

That means you can have:

Write-offs can make the picture even less clear.

An account disappearing from open A/R because it was adjusted off is not the same thing as an account disappearing because it was paid.

The better question is not just:

How much did we collect this month?

It is:

Is the inventory behind those collections getting healthier or getting worse?

There is no single cause, but several patterns show up frequently.

Denials are aging without being resolved

A denied claim does not stop aging just because it moved into a denial queue.

If there is no clear next action, the balance continues to sit.

That becomes especially costly when the same denial reason keeps repeating. The team spends time correcting the same eligibility, authorization, or coding issue while older denied claims continue moving deeper into aging.

The goal should be both to work the current denial and understand why it keeps happening. Related reading: how to reduce preventable medical billing denials and denial management.

Accounts have a status, but no real next action

“Pending.”

“In process.”

“Follow up.”

Those may describe where an account sits, but they do not tell you what is actually happening next.

A useful follow-up record should make clear:

Without that, an account can look active while sitting untouched for weeks.

The team is prioritizing by age alone

Oldest-first sounds logical.

But age should not be the only thing determining priority.

A newer high-dollar claim with an approaching filing or appeal deadline may deserve attention before a small balance that has already been sitting for months.

The better prioritization approach considers:

High-dollar claims are getting lost in the volume

A billing team can close a large number of small claims and still leave significant revenue sitting.

Ten low-dollar claims may represent less money than one large procedure claim.

Claim count can make a work queue look productive even when the largest balances are not moving.

That is why practices should review A/R by dollars as well as by number of accounts.

Patient A/R is growing

Insurance A/R and patient A/R should not automatically be treated as the same inventory.

Patient balances may grow because of:

Insurance payments from earlier months can keep total collections looking healthy while patient balances continue increasing.

Underpayments are being treated as completed claims

A paid claim often disappears from open A/R.

But “paid” does not always mean “paid correctly.”

If a payer reimburses less than expected and the difference is posted as a contractual adjustment, that account may never show up as aging A/R again.

That means a practice can have two different forms of revenue leakage at the same time:

Open claims that are getting older, and closed claims that may have been underpaid.

They require different types of review. See also underpayment recovery and how medical practices can identify insurance underpayments.

A 120-day-old balance is not automatically dead.

And it is not automatically worth chasing.

What matters is whether there is still a path to payment.

Potentially recoverable A/R might include:

Other balances may have very little recovery potential because:

The goal is not to chase every old balance forever.

It is to identify which accounts still have a realistic path to payment and focus the team there.

Technology can help surface patterns by age, payer, balance, denial reason, and last activity.

But people still need to decide what should be pursued and what the next action should be.

A growing A/R balance does not automatically mean you need a new billing company.

Sometimes the practice simply needs clearer reporting or a better process for prioritizing open accounts.

Outside help may be worth considering when:

That is where focused A/R recovery can help.

The goal is not simply to call on old claims.

It is to determine what is recoverable, prioritize the accounts that still have a path to payment, and move those accounts toward resolution.

If collections look fine but A/R keeps growing, start with the data you already have.

Look at aging by bucket.

Separate insurance from patient balances.

Review the highest-dollar claims.

Identify denials sitting inside A/R.

And find out which open accounts do not have a clear next action.

If you want an independent review, VeroRCM's Free Revenue Leak Audit can look at available claims, denials, payments, underpayments, and aging A/R to identify areas that may deserve closer attention.

There is no requirement to switch billing companies first.
