The Window Before RCM: How Charge Holds, Charge Lag and Denials Shape Your Cash Flow

Most physician group owners know their days in AR, or can find it quickly. Far fewer can tell you how many days pass before a charge even reaches billing.

That stretch, from the moment a provider sees a patient to the moment the charge is released to your billing team or billing company, is what I call the window before RCM. It rarely shows up on revenue cycle reports, because technically the revenue cycle hasn’t started yet. But it decides how soon you get paid, and whether some charges get paid at all.

When I led operations for hospitalist and post-acute physician groups, charge lag was one of the reports I reviewed every week, for one simple reason: cash is king. A charge that sits for a week is a week of cash that isn’t in the bank. A charge that sits long enough, or goes out wrong, may never turn into cash.

This post walks through what happens in that window, the questions to ask before you trust your numbers, and a simple way to put a dollar figure on a day of lag.

What happens in the window before RCM

Every charge goes through some version of the same four steps before it becomes a claim:

• It waits to be entered. The provider documents the visit and, at some point, a charge is created. The gap between date of service and charge entry is your charge lag.
• It waits on something. A note isn’t signed, a coder has a question for the provider, the patient’s demographics or insurance are incomplete. The charge sits on hold until someone clears it.
• It gets checked, or it doesn’t. Edits catch missing modifiers, mismatched diagnosis and procedure codes, wrong place of service, and missing registration details. Anything that isn’t caught here goes out with the claim.
• It’s released to billing. From here, the revenue cycle report you already know takes over.

Each step adds days. Some steps also add risk. Let’s take them one at a time.

Charge lag: three questions before you trust the number

Plenty of groups track charge lag. The trouble is that the number on the report can hide more than it shows. Before you act on it, ask:

1. Is it measured the same way everywhere?

Some reports measure from date of service to charge entry. Others measure to claim submission, which quietly includes hold time and billing office processing. If your billing system holds every claim a set number of days on purpose, to give late charges a chance to arrive, make sure those built-in days are separated out. Otherwise a perfectly healthy process looks slow, or a slow one gets excused.

2. Are you looking at the average, or the tail?

An average lag of four days can be a group where everyone enters charges within four days. It can also be a group where most providers enter the same day and two providers enter charges once a week. Those are very different problems. Break lag out by provider and by site, and look at the slowest 10% of charges, not just the middle. In most groups, a handful of providers or locations drive most of the delay, and that is where the fix is.

3. What should it be?

HFMA’s guideline is that charges should be captured within three to five days of service, and that late charges should not exceed 2% of total charges. For providers rounding in a hospital every day, there’s little reason for a charge to wait more than a day or two. Set your own target, measure the trend month over month, and watch the outliers.

Why lag happens. It often comes down to workflow: charges batched at the end of a long day, entered after the provider has left the facility, delayed because the patient isn’t registered yet at a site with no interface, or blocked behind an unsigned note. One habit helps more than you’d expect: a quick end-of-day review of the full patient list. Our providers told us it helped them wrap up their day, and it jogged memories we would otherwise have lost: “Oh, that’s right, I ordered a CT on that patient.”

Charge holds: the queue nobody owns

Lag gets attention because it’s easy to put on a chart. Holds are quieter, and in many groups no one person is responsible for them.

Charges usually go on hold for one of four reasons:

• Intentional hold days, set in the billing system so late charges can catch up before the claim drops.
• Documentation holds. An unsigned or incomplete note blocks the charge. Whatever is in your unsigned-note queue is effectively a ceiling on what you can bill this week.
• Coding queries. A coder needs the provider to clarify a level, a diagnosis or a procedure, and the charge waits until the provider answers.
• Missing patient information. Demographics or insurance details aren’t complete, often because the patient was seen somewhere the group has no data feed.

The problem with holds is that they age silently. A coding query sent on Tuesday can still be open three weeks later, and unless someone is looking, nothing flags it. One large health system we work with came to us for exactly this reason: its EHR gave it no reliable way to see whether an encounter had been billed, or whether a physician had ever responded to a coder’s query.

Four questions every owner can ask their billing lead:

• How many charges are on hold today?
• How old is the oldest one?
• How many provider queries have been open more than a week?
• Who is responsible for clearing the queue, and how often do they work it?

Denials start before billing does

It’s tempting to think of denials as something that happens after the claim goes out. In practice, most of them are set up earlier.

Change Healthcare’s analysis of 102 million hospital claims found that 86% of denials were potentially avoidable, and that about half originated with front-end issues such as registration and eligibility, which alone accounted for 27% of denials. Experian Health’s 2025 State of Claims survey found that 41% of providers say at least one in ten claims is denied, with missing or inaccurate data, authorization issues and incomplete patient information at the top of the list.

The cost doesn’t end with the rework, which runs about $25 per claim. The same Change Healthcare analysis found that nearly half of avoidable denials are never recovered.

The cheapest denial to fix is the one that never leaves the building. That means checking charges before they’re released: confirming demographics and eligibility, matching diagnosis to procedure, applying the right modifiers and place of service, and making sure documentation supports the level billed.

Authorization is the hardest of these for physician groups, because the rules keep changing and often sit with the payer, not the group.

What a day of lag costs: run your own numbers

Owners often hear revenue cycle problems described in big annual numbers that are hard to picture. A more useful way to think about lag is in days and in providers.

Here’s the method, using your own figures:

1. Find your average daily collections. Take a typical month’s collections and divide by 30.
2. Multiply by the days of lag you could remove. That is roughly the cash you would bring into the bank sooner.
3. Divide by your number of providers to see it per provider.

For example, a group collecting $1.2 million a month brings in about $40,000 a day. If it cut its charge lag by five days, about $200,000 would arrive sooner. Across 20 providers, that’s about $10,000 per provider.

Be clear about what this is: a one-time improvement in timing, not new revenue. But timing matters more than it used to. Traditional Medicare typically pays clean claims in 10 to 14 days, while Medicare Advantage plans often take 30 to 45 (MGMA), and more than half of eligible Medicare beneficiaries are now in Medicare Advantage (KFF). The payer’s clock is getting longer. The days before the claim leaves your office are the part you control.

When lag becomes loss. Every payer has a timely filing limit. Medicare’s is 12 months from the date of service, and many commercial contracts are shorter, so check yours. Lag also costs accuracy: a charge entered days after the visit is entered from memory, and memory tends to round down. And a charge that is never entered doesn’t show up as lag at all. It just disappears, which is why reconciliation, comparing the encounters you expected against the charges you received, belongs in this window too.

Five numbers to ask for every month

You don’t need a new dashboard to start managing the window before RCM. Ask your billing lead or practice administrator for these five numbers, and for what they plan to do when one is off:

1. Charge lag by provider and site, showing both the median and the slowest 10%. If it’s off: talk to the two or three slowest providers about when and where they enter charges.
2. Charges on hold, and the age of the oldest. If it’s off: assign an owner and a weekly clearing target.
3. Provider queries open more than seven days. If it’s off: route queries where providers will see them and follow up at a set time each week.
4. Initial denial rate and its top three reasons. HFMA puts the typical range at 5–10%, with under 5% as the goal. If it’s off: move the top reason upstream as an edit before release.
5. Encounters with no charge after your reconciliation window. If it’s off: find out whether the visit happened and was never billed, or was billed somewhere you can’t see.

Where medaptus fits

Charge Pro works in exactly this window, alongside your EHR and your billing system. Providers enter charges at the point of care, on mobile or desktop, so they aren’t saved up for the end of the day. Charges are automatically run through the Medaptus Rules Engine before they’re released, so common errors are caught while they’re still cheap to fix. Reconciliation compares the encounters you expected against the charges you received, so missing charges surface while there’s still time to bill them. And for sites where your group has no data feed, face sheet capture, coming in the Nov 16 Charge Pro release, lets a provider photograph the patient’s face sheet, register the patient and enter the charge before leaving the room.

Charge Pro doesn’t replace your billing team or billing company. It hands them cleaner charges, sooner.

The part of the revenue cycle you control

Days in AR, payer mix and payment timelines all matter, but much of what drives them sits with payers. The window before RCM is different. It’s made of your providers, your workflows and your queues, which means it’s the part you can actually change, often within a quarter.

Start with the five numbers above. Find the providers and sites driving most of your lag, give someone ownership of the hold queue, and move your most common denial reason upstream. The cash was always yours. The goal is to stop making it wait.
