CO-175 Denials Explained: How to Identify, Appeal, and Prevent Them

One of the most frustrating denial codes revenue cycle management (RCM) teams encounter is CO-175, which indicates an incomplete prescription. These denials can interrupt cash flow, increase operational burdens, and erode payer-provider relationships. Understanding this denial code is essential for healthcare organizations seeking to maintain efficiency and reduce revenue leakage.

In this article, we’ll explore what CO-175 denials mean, why they occur, and how RCM professionals can effectively appeal and prevent them. With proper strategies and technology, such as CombineHealth.ai’s tools like Adam and Rachel, organizations can stay ahead of denial challenges.

What Is a CO-175 Denial?

CO-175 is a contractual obligation denial code used by payers to inform providers that the submitted prescription lacks required information or elements. This typically occurs when details like dosage instructions, physician credentials, or patient identifiers are incomplete or missing.

The prefix “CO” denotes that the payer considers the denial the provider’s responsibility due to submission errors. This means the financial burden of rework falls on the provider rather than the patient or payer. Providers must address such denials promptly to recover lost revenue and avoid write-offs.

Comparison: CO-175 vs Similar Denial Codes

Denial Code	Prefix Meaning	Reason/Description	Who's Financially Responsible
CO-175	Contractual Obligation	Prescription is incomplete.	Provider
CO-16	Contractual Obligation	Claim lacks information or required fields.	Provider
CO-167	Contractual Obligation	Diagnosis code missing or invalid.	Provider

While CO-175 focuses specifically on incomplete prescriptions, other codes like CO-16 or CO-167 relate to missing or incorrect claim data, such as diagnosis codes. The primary similarity is the responsibility, which remains with the provider for ensuring accurate and complete submissions.

Common Causes of CO-175 Denials

1. Missing Prescription Details: Essential elements, such as dosage instructions or drug name, are omitted during submission.
2. Invalid or Incomplete Physician Information: The physician’s National Provider Identifier (NPI) or license details are either incorrect or missing.
3. Patient Information Errors: Critical patient identifiers, such as name, date of birth, or insurance ID, are incomplete.
4. Noncompliance with Payer-Specific Requirements: Payer-specific formatting or documentation standards for prescriptions are not met.

Impact on Revenue Cycle Teams

CO-175 denials pose both financial and operational challenges for RCM teams:

Financial Impact:
- Revenue Loss: Rejected claims delay reimbursements and strain cash flow.
- Increased Accounts Receivable (AR) Days: Prolonged resolution timelines extend AR cycles.
- Write-Off Risk: Unresolved denials may result in losses if appeals fail or deadlines are missed.
- Operational Cost Burden: Additional staff hours are required for denial management, reducing overall efficiency.

Operational Impact:
- Disrupted Workflow: Teams must divert resources from other priority functions to handle denials.
- Documentation Complexity: Payers often require detailed clinical records to resolve CO-175 denials.
- Cross-Department Coordination: Successful resolution requires collaboration across billing, coding, and clinical teams.
- Denial Tracking Challenges: Identifying patterns and managing appeal outcomes demand specialized tools and expertise.

Leveraging AI-powered solutions like CombineHealth.ai’s Adam can help RCM teams automate denial identification, optimize workflows, and better manage appeals. Combined with Rachel’s streamlined appeals process, healthcare organizations can reduce operational strain while improving cash flow.

Steps To Appeal a CO-175 Denial

Step 1: Review the Denial Notice

Step 3: Verify Eligibility
Confirm patient coverage and ensure all details align with the payer’s documentation requirements.

Step 4: Prepare Appeal Letter

Step 5: Submit Within Deadline
Ensure the appeal is submitted within the payer’s specified timeframe to avoid forfeiting reimbursement opportunities.

Step 6: Track and Follow Up
Monitor the status of the appeal and maintain communication with the payer to expedite resolution.
