Split Billing And Shared Visits: Criminal Exposure In Hospital And Group Practice Settings

In modern healthcare delivery, physicians frequently collaborate with nurse practitioners and physician assistants to provide timely, efficient care, especially in hospital and group practice settings. “Split” or “shared” visit billing (often called split/shared E/M services) is designed to reflect that collaborative model. But the rules governing how services are divided, documented, and billed are technical and evolving.

When those rules are misunderstood or inconsistently applied, routine team-based care can be recast as improper billing. In today’s enforcement climate, that recasting can escalate from an audit to allegations under the False Claims Act, or even criminal charges.

If your practice relies on shared visits, consulting an experienced Florida healthcare fraud lawyer is essential to protect your operations and your professional standing.

What Split/Shared Billing Is Meant to Do

Split/shared billing allows a physician and a qualified non-physician practitioner (NPP) to both contribute to an evaluation and management (E/M) service, with the claim billed under the appropriate provider based on who performed the “substantive portion” of the visit. Historically, the substantive portion could be tied to history, exam, or medical decision-making (MDM); more recent guidance emphasizes time or MDM depending on the setting and year of service. The goal is straightforward: align reimbursement with the clinician who meaningfully delivered the service while recognizing team-based care.

The complexity lies in the details—what counts as the substantive portion, how time is tracked, how MDM is attributed, and how documentation must reflect each provider’s contribution. Small gaps in these areas are where risk accumulates.

Where Practices Commonly Go Wrong

In busy inpatient and group settings, workflows often outpace compliance protocols. NPPs may perform the bulk of the visit, while physicians add a brief note or sign off later. Templates and macros can blur who did what. Time may not be tracked with precision. Over time, these patterns can drift away from regulatory requirements.

A frequent issue is billing under the physician when the NPP actually performed the substantive portion of the service. Another is inadequate documentation of each provider’s contribution—notes that do not clearly distinguish time, MDM, or distinct work performed. In teaching environments, confusion can deepen when residents or fellows are also involved, creating layered documentation that is difficult to reconcile.

None of these scenarios necessarily reflects intent to deceive. But they can create a record that, when reviewed retrospectively, appears inconsistent with billing rules.

From Documentation Gap to False Claims Allegation

When auditors identify discrepancies between documentation and billing, cases often begin as overpayment reviews. The government may seek repayment for services billed under the wrong provider or at the wrong rate. But repeated discrepancies can be reframed as a pattern, which is one that prosecutors argue reflects knowledge or reckless disregard.

Under the False Claims Act, liability can attach if a provider knowingly submits false claims or causes them to be submitted. “Knowledge” includes deliberate ignorance or reckless disregard. If a practice consistently bills shared visits under the physician without adequate support for the physician performing the substantive portion, investigators may argue that the practice should have known the claims were improper.

If there is evidence, such as emails, training materials, or prior audit findings, suggesting awareness of the rules, the government’s theory may escalate from civil liability to criminal exposure under healthcare fraud statutes. The narrative shifts from “we made mistakes” to “they engineered billing to maximize reimbursement.”

How Prosecutors Argue Intent in Shared Visit Cases

Intent is often the central battleground. Prosecutors typically rely on patterns: a high percentage of shared visits billed under physicians, minimal physician documentation, or time entries that do not align with schedules. They may also highlight internal communications discussing productivity, revenue targets, or staffing constraints.

From the government’s perspective, these data points suggest that billing decisions were driven by financial incentives rather than compliance. From the defense perspective, they reflect the realities of team-based care, documentation burdens, and evolving regulatory guidance.

The gap between those perspectives is where cases are won or lost.

The Role of Evolving CMS Guidance

Compounding the risk is the fact that CMS guidance on split/shared visits has changed in recent years. Definitions of the “substantive portion,” acceptable documentation, and time-based billing have all evolved. Practices that relied on prior guidance may find their processes out of step with current expectations.

Investigators often evaluate claims using the rules in effect at the time of service, but in practice, enforcement can reflect newer interpretations. This creates a moving target for providers trying to remain compliant.

Defending Shared Visit Allegations

An effective defense begins with reconstructing what actually happened in the clinical setting. Defense teams review schedules, staffing models, EHR audit trails, and time logs to demonstrate who performed the substantive portion of services. Where documentation is imperfect, context becomes critical, explaining workflows, handoffs, and how care was delivered.

Expert testimony is often central. Clinicians can explain standard practices in hospital medicine or specialty care, clarifying why documentation may not neatly mirror billing categories while still reflecting legitimate services.

Equally important is demonstrating good-faith compliance efforts. Training records, policy updates, and internal audits can show that the practice was attempting to follow complex, changing rules. Where guidance was ambiguous, a reasonable interpretation can undercut claims of knowing misconduct.

Preventing Exposure Going Forward

Prevention requires aligning operations with current CMS guidance. Practices should clearly define what constitutes the substantive portion of a visit, implement reliable time-tracking where applicable, and ensure documentation distinguishes each provider’s contribution. Regular audits focused specifically on shared visits can identify patterns before they become enforcement issues.

Education is key. Physicians and NPPs must understand not only how to deliver care collaboratively, but how to document and bill that care in a way that withstands scrutiny.
