Case Study Overview

When Facility Participation and Physician Participation Don't Align

A hospital can be in-network with an insurance plan while a physician treating patients inside that hospital is not.

For hospitalists and other hospital-based physicians, this distinction can create a complicated revenue-cycle environment. The hospital's payer contracts and the physician's or physician group's payer relationships may be separate, creating different network and reimbursement considerations.

The key question isn't only: “Is the hospital in-network?”
The provider also needs to understand whether the physician is properly credentialed, enrolled, contracted, affiliated, and configured to bill the applicable payer.
The Challenge

The Hospital Is In-Network. The Physician Isn't.

Facility participation does not automatically establish the physician's payer participation status.

The Revenue-Cycle Risk

The Hidden Problem Behind Unresolved Claims

Hospital-based physicians may provide services at facilities that participate with commercial insurance plans even when the physician or physician group has a different relationship with the payer.

This can create questions around network participation, credentialing, Medicare and Medicaid enrollment, provider demographics, billing setup, claim submission, out-of-network reimbursement, and payer-specific requirements.

  • Claims not being submitted
  • Claims being rejected or denied
  • Missing payer enrollment information
  • Incorrect provider demographics
  • Credentialing applications still pending
  • Group affiliation not updated
  • Billing setup not completed
  • Underpayments requiring follow-up
ABC's Approach

Connect Credentialing to Revenue

ABC does not treat credentialing, payer enrollment, and medical billing as isolated administrative functions. We look at how these components connect across the provider's revenue cycle.

01

Assess the Provider's Payer Status

ABC begins with a payer-by-payer assessment to understand the provider's current enrollment, credentialing, participation, and demographic status.

  • Individual provider enrollment
  • Group enrollment
  • Credentialing status
  • Contract participation
  • Provider effective dates
  • Payer affiliations
  • NPI and taxonomy information
  • Revalidation status
02

Separate Hospital Participation From Physician Participation

ABC helps providers distinguish the hospital's network relationship from the physician's own payer relationship.

This provider-level review helps establish the appropriate billing strategy instead of assuming that facility participation automatically applies to the physician.

03

Establish the Appropriate Billing Workflow

ABC helps coordinate the billing workflow based on payer, provider status, service, documentation, and applicable requirements.

  • In-network claim workflows
  • Out-of-network claim workflows
  • Payer-specific claim requirements
  • Supporting documentation
  • Claim status follow-up
  • Denial management
  • Underpayment review
  • Appeals and reconsiderations where appropriate
04

Address Medicare Enrollment

Commercial payer participation and Medicare enrollment should not be treated as the same process.

ABC supports the administrative work surrounding Medicare enrollment, revalidation, provider information maintenance, and related enrollment processes.

05

Address Medicaid Enrollment

Medicaid requirements can vary by state and provider type. ABC helps providers identify applicable enrollment and maintenance requirements and coordinate the associated administrative work.

06

Keep Provider Information Current

Credentialing does not end when an application is approved. Provider demographics, affiliations, locations, licenses, and enrollment information may change over time.

07

Connect Credentialing With Claims

ABC brings credentialing, enrollment, billing, follow-up, denial management, and revenue-cycle support into a connected workflow.

Out-of-Network Does Not Mean “Bill Without Limits”

Out-of-network billing requires careful handling. Federal No Surprises Act protections apply in specified circumstances, including certain emergency services and certain non-emergency services provided by out-of-network providers at in-network facilities.

Billing workflows need to account for the applicable rules.

Depending on the situation, the review may include the patient's insurance type, service provided, facility setting, emergency versus non-emergency circumstances, notice and consent requirements where applicable, federal requirements, state requirements, and payer rules.

ABC's approach is to build billing workflows around the applicable payer and regulatory requirements rather than treating every out-of-network claim the same way.

The ABC Revenue-Cycle Perspective

Don't Look at the Claim in Isolation.

When credentialing and billing are disconnected, revenue-cycle gaps can be difficult to identify. ABC looks across the provider's complete administrative and billing workflow.

Revenue Warning Signs

Is Your Hospitalist Revenue Cycle Leaving Claims Behind?

You may need to take a closer look if your organization is experiencing any of the following:

Claims that are not being submitted
Unexpected payer denials
Providers who are not fully enrolled
Credentialing applications pending for extended periods
Incorrect provider demographics
Missing payer affiliations
Unclear network participation
Medicare or Medicaid enrollment issues
Unresolved out-of-network claims
Increasing accounts receivable
The ABC Difference

Credentialing Alone Isn't Enough.

A provider can be credentialed and still have billing problems. A billing team can submit claims, but enrollment or payer setup issues can create reimbursement obstacles.

C

Credentialing

Support provider participation and enrollment requirements.

B

Billing

Support claim preparation, submission, follow-up, denials, and reimbursement workflows.

R

Revenue Cycle

Connect provider data, payer relationships, claims, payments, and follow-up.

Case Study Note: This case study is presented as an operational example of the challenges hospital-based physicians can encounter when facility network participation, physician participation, credentialing, enrollment, and billing workflows do not align. Specific payer rules, reimbursement terms, patient protections, and enrollment requirements vary by payer, plan, state, provider type, and service. Results and reimbursement outcomes may vary.
