PR-78 Denials Explained: How to Identify, Appeal, and Prevent Them

Denial codes like PR-78 can create significant challenges for healthcare revenue cycle management (RCM) teams, leading to financial strain and operational inefficiencies. PR-78 denials specifically address non-covered days or room charges that fall under the patient’s responsibility—an issue that can often result from avoidable errors or misunderstandings.

In this article, we’ll break down the PR-78 denial code, its common causes, how it impacts RCM operations, and actionable strategies to appeal and avoid these denials in the future.

What Is a PR-78 Denial?

The PR-78 denial code signifies that the claim includes non-covered days or room charges, which are deemed the patient’s financial responsibility.

• Prefix Explanation: The “PR” prefix stands for “Patient Responsibility,” meaning the payer has determined that the patient, not the provider or insurer, is liable for these charges. Other prefixes, such as “CO” (Contractual Obligation) or “OA” (Other Adjustment), indicate different types of adjustments, but PR signals direct patient accountability.
• Financial Responsibility: For PR-78 denials, the patient is responsible for covering the charges outlined in the denial notice.

Understanding this distinction is critical, as it determines how the denial is addressed—either through patient communication or an appeal to the insurer.

Comparison: PR-78 vs Similar Denial Codes

Denial Code	Prefix Meaning	Reason/Description	Who's Financially Responsible
PR-78	Patient Responsibility	Non-Covered days/Room charge adjustment	Patient
CO-45	Contractual Obligation	Charge exceeds payer’s allowable amount	Provider
PR-96	Patient Responsibility	Non-covered service under the policy	Patient

While PR-78 and PR-96 both attribute costs to the patient, PR-78 specifically applies to room charges or inpatient stay dates. CO-45 differs in that it reflects payer-provider contractual adjustments, not patient-related liabilities.

Common Causes of PR-78 Denials

1. Policy Exclusions: The patient’s insurance plan does not cover specific inpatient stay dates or room charges.
2. Incorrect Insurance Information: Errors in verifying the patient’s coverage or eligibility can lead to denials for uncovered services.
3. Authorization Issues: Missing or expired prior authorizations for inpatient stays result in non-covered charges.
4. Documentation Errors: Missing or incomplete clinical documentation may lead payers to deny certain room charges.
5. Late Filing: Claims submitted beyond the payer’s deadline for the service dates in question.

Impact on Revenue Cycle Teams

PR-78 denials have both financial and operational repercussions, requiring significant time and resources to address.

Financial Impact

• Revenue Loss: Denied claims mean deferred or lost revenue, especially if appeals aren’t submitted on time.
• Increased AR Days: PR-78 denials prolong accounts receivable turnover, delaying cash flow.
• Write-offs: Unsuccessful appeals or deadlines missed can force providers to absorb costs.
• Higher Costs: Additional denial management efforts increase operational expenses.

Operational Impact

• Staff Time: RCM staff must dedicate time to researching, appealing, and resolving PR-78 denials.
• Coordination Challenges: Effective resolution often requires collaboration between billing, coding, and clinical teams.
• Denial Trends: Teams must analyze patterns to identify root causes and avoid recurring issues.

Steps To Appeal a PR-78 Denial

Appealing PR-78 denials requires a structured approach to maximize success rates:

Step 1: Review the Denial Notice
Carefully analyze the Explanation of Benefits (EOB) or Remittance Advice (RA) to understand why the charges were denied.

Step 2: Gather Documentation
Collect all relevant documents, such as the patient’s insurance policy, clinical records, and prior authorizations, to support the appeal.

Step 3: Verify Eligibility
Confirm that the patient’s insurance coverage was active during the dates of service and that the charges align with policy terms.

Step 4: Prepare Appeal Letter
Draft a detailed appeal letter that includes:
- Patient and claim information
- Reason for appeal
- Supporting documentation
- Clear request for claim reconsideration

Step 5: Submit Within Deadline
Ensure the appeal is submitted before the payer’s specified deadline, as late appeals are typically rejected outright.

Step 6: Track and Follow Up
Monitor the appeal’s status through payer portals or direct communication. Follow up proactively to address additional requests or delays.

How To Prevent PR-78 Denials

Preventing PR-78 denials is more efficient than addressing them post-denial. Here are targeted strategies:

Front-End Prevention

• Eligibility Verification: Use automated tools to verify patient coverage and benefits before the service is rendered.
• Prior Authorizations: Confirm that all inpatient stays have proper authorizations in place and that they are valid during the service dates.

Billing Best Practices

• Accurate Documentation: Ensure clinical documentation supports the charges billed, particularly for inpatient services.
• Timely Submissions: File claims promptly to avoid payer deadlines and reduce the risk of denials.

Technology Solutions

• Real-Time Claim Scrubbing: Implement tools like CombineHealth.ai’s Adam to identify potential denials before claim submission.
