OA-75 Denials Explained: How to Identify, Appeal, and Prevent Them

For healthcare revenue cycle management (RCM) teams, denial codes like OA-75 represent a recurring challenge that can disrupt claim workflows and delay reimbursements. The OA-75 code, specifically tied to payment adjustments for Direct Medical Education (DME) costs, requires teams to have a clear understanding of its implications. Without proper handling, these denials can lead to revenue loss and operational inefficiencies.

In this blog, we’ll unpack the OA-75 denial code, explain its causes and impact, and provide actionable steps to appeal and prevent these denials.

What Is a OA-75 Denial?

The OA-75 denial code refers to a Direct Medical Education Adjustment made by payers to account for the costs incurred by teaching hospitals in training medical residents. The “OA” prefix stands for Other Adjustment, indicating that the denial is not tied to patient responsibility or contractual obligations but rather to an adjustment outside the usual claim requirements.

In the case of OA-75 denials, the payer typically bears the financial responsibility, as this adjustment reflects reimbursement policies related to medical education rather than a billing error or patient liability.

Comparison: OA-75 vs Similar Denial Codes

Denial Code	Prefix Meaning	Reason/Description	Who's Financially Responsible
OA-75	Other Adjustment	Direct Medical Education Adjustment	Payer
CO-45	Contractual Obligation	Charges exceed payer contract rates	Provider
PR-1	Patient Responsibility	Deductible amount	Patient

While OA-75 denotes an adjustment for teaching hospitals, CO-45 and PR-1 reflect denials tied to contract terms or patient liabilities. Understanding these distinctions helps RCM teams allocate responsibility and address denials appropriately.

Common Causes of OA-75 Denials

1. Insufficient Documentation: Missing or incomplete documentation validating the hospital’s status as a teaching facility.
2. Incorrect Billing Codes: Errors in coding related to medical education costs, leading to claim rejection.
3. Payer Policy Discrepancies: Misalignment with payer-specific rules for Direct Medical Education reimbursements.
4. Late Claim Submission: Filing claims outside the payer’s allowable timeframe for DME adjustments.
5. Lack of Coordination Between Teams: Miscommunication between billing and clinical teams regarding required documentation.

Impact on Revenue Cycle Teams

OA-75 denials can significantly impact the financial health and operational efficiency of healthcare organizations.

Financial Impact:
- Revenue leakage due to claim rework or write-offs.
- Longer accounts receivable cycles, straining cash flow.
- Increased costs from dedicating resources to denial resolution.

Operational Impact:
- Diverted staff time from proactive RCM activities to reactive denial management.
- Need for specialized training on payer-specific DME policies.
- Increased complexity in coordination between billing, coding, and clinical teams.

To address these challenges, healthcare organizations benefit from advanced denial management tools. CombineHealth.ai’s Adam (AI Denial Manager) offers comprehensive tracking and resolution capabilities, helping teams streamline workflows and reduce revenue loss from OA-75 denials.

Steps To Appeal a OA-75 Denial

Here are the key steps RCM teams can take to effectively appeal OA-75 denials:

Step 1: Review the Denial Notice
Carefully examine the explanation of benefits (EOB) or remittance advice (RA) to confirm the denial reason.

Step 2: Gather Documentation
Collect all necessary documentation, including proof of the hospital’s teaching status and any supporting data for DME costs.

Step 3: Verify Eligibility
Ensure the claim meets payer-specific requirements for DME reimbursement, including accurate coding.

Step 4: Prepare Appeal Letter
Draft a clear and concise appeal letter that outlines why the adjustment was incorrect. Include all supporting documentation and reference payer policies.

Step 5: Submit Within Deadline
Ensure the appeal is submitted within the specified timeframe to avoid automatic denial.

Step 6: Track and Follow Up
Monitor the status of the appeal and follow up with the payer if no response is received within the expected timeframe.
