A new hospitalist joins the group and starts rounding. The clinical work begins on day one. The billing cannot -- and by the time credentialing is complete, some of that early revenue may already be gone.
New providers must be credentialed by each payer before their claims can be processed. That process typically takes four to eight weeks. CMS allows retroactive billing for encounters during that window -- but only within 30 days of credentialing being finalized. Miss that deadline and those encounters cannot be billed. The revenue is lost permanently.
SHM's 2025 State of Hospital Medicine report found that 64% of hospitalist groups expect to grow their provider count in the near term. For a growing group, this is not a one-time risk. Every new hire restarts the credentialing cycle with every payer. A group adding two or three providers a year is running this exposure multiple times, simultaneously, across a full payer mix.
The dollar impact adds up fast. Encounters from a new provider's first few weeks -- before credentialing clears -- represent real clinical work that generated real revenue. When the retroactive billing window closes before those claims go out, that revenue disappears from the AR permanently. It does not show up as a denial. It simply never appears.
Credentialing is typically managed by a separate administrative function -- HR, a credentialing coordinator, or an outside service. Billing teams often do not receive real-time updates on where each new provider stands in the payer enrollment process.
Without that connection, billing workflows for a new provider run on assumptions. The billing team assumes credentialing is complete. The credentialing coordinator assumes billing knows the status. Claims go out correctly -- or not at all -- depending on which assumption was wrong.
This problem rarely triggers an obvious alarm. Claims for an uncredentialed provider may be denied quietly, returned without payment, or simply never submitted if the billing team holds them pending a credentialing confirmation that never arrives.
By the time anyone adds up what revenue was lost during the gap, the retroactive billing window may have already closed. The encounters were real. The work was done. The revenue is gone.
The fix requires a connection between credentialing timelines and billing workflows that most groups do not have built. When billing teams know -- in real time -- where each new provider stands in the payer enrollment process, retroactive billing can begin the moment credentialing clears. Filing windows can be tracked rather than missed.
ChartPath works with hospitalist groups to ensure those windows are captured and no eligible encounter is lost to a timing gap that a more connected process would have caught.
ChartPath's free AR Assessment includes a review of your group's billing patterns, including gaps that may indicate credentialing-related revenue loss. The assessment is read-only, requires no changes to your existing billing workflow, and comes with a written report and a 30-minute walkthrough. If revenue is leaking through new-provider billing gaps, the assessment will show you where.
