Durable Medical Equipment (DME) and orthotics providers are increasingly subject to Medicare audit activity, particularly through the Recovery Audit Contractor (RAC) program. One of the most prominent RAC contractors is Cotiviti, which is responsible for identifying improper payments and recovering overpayments on behalf of the Centers for Medicare & Medicaid Services.

A Cotiviti RAC audit is a high-stakes review that can result in significant financial recoupments, extrapolated overpayment demands, and prolonged appeals processes. Providers must understand how these audits work, what triggers them, and how to prepare.

This article provides a comprehensive guide to Cotiviti RAC audits in the DME and orthotics space and outlines strategies to reduce risk and ensure compliance.

What Is a RAC Audit?

The RAC program was established by CMS to identify and recover improper Medicare payments.

RAC audits focus on:

  • Overpayments due to billing errors

  • Lack of medical necessity

  • Documentation deficiencies

  • Coding inaccuracies

Unlike UPIC audits, RAC audits are primarily financial and retrospective, targeting claims that have already been paid.

Why Cotiviti Targets DME and Orthotics Providers

DME and orthotics providers are frequently audited due to:

  • High claim volumes

  • Standardized coding structures (HCPCS)

  • Historical overpayment rates in these categories

Cotiviti uses data analytics to identify providers with:

  • Outlier billing patterns

  • High utilization rates

  • Unusual coding trends

Types of Cotiviti RAC Reviews

1. Automated Reviews

These reviews do not require medical records.

They focus on:

  • Duplicate claims

  • Incorrect billing logic

  • Obvious coding errors

Overpayments are identified based on claims data alone.

2. Complex Reviews

Complex reviews require submission of medical records.

Cotiviti evaluates:

  • Medical necessity

  • Physician orders

  • Supporting documentation

These reviews pose higher risk due to detailed clinical scrutiny.

What Cotiviti Reviews in DME and Orthotics Audits

1. Medical Necessity

Documentation must support that:

  • The equipment or orthotic device is medically necessary

  • It is appropriate for the patient’s condition

  • It meets Medicare coverage criteria

Insufficient documentation is the most common reason for denials.

2. Physician Orders and Face-to-Face Requirements

Orders must be:

  • Signed and dated

  • Specific to the item provided

  • Supported by face-to-face encounter documentation (if required)

Missing or incomplete orders are a frequent deficiency.

3. Proof of Delivery

Providers must demonstrate that the item was delivered to the patient.

Acceptable documentation includes:

  • Delivery receipts

  • Signed confirmation forms

  • Shipping records

4. Coding and Billing Accuracy

Claims must include:

  • Correct HCPCS codes

  • Appropriate modifiers

  • Accurate units

Coding errors can trigger denials and extrapolation.

5. Coverage Criteria Compliance

Each DME or orthotic item must meet Medicare Local Coverage Determinations (LCDs) or National Coverage Determinations (NCDs).

Failure to meet coverage criteria results in claim denial.

Common Deficiencies Identified by Cotiviti

Cotiviti frequently identifies:

  • Lack of medical necessity documentation

  • Missing or invalid physician orders

  • Failure to meet LCD requirements

  • Incorrect coding or modifiers

  • Missing proof of delivery

These deficiencies often lead to overpayment determinations.

The RAC Audit Process

Step 1: Additional Documentation Request (ADR)

Cotiviti sends an ADR requesting records.

The letter includes:

  • List of claims under review

  • Documentation requirements

  • Submission deadline

Step 2: Documentation Review

Cotiviti reviews submitted records for compliance.

Step 3: Determination

If issues are found:

  • Claims are denied

  • Overpayments are calculated

Step 4: Recoupment

Medicare initiates recoupment of identified overpayments.

Step 5: Appeals Process

Providers can appeal through multiple levels, including:

  • Redetermination

  • Reconsideration

  • Administrative Law Judge (ALJ) hearing

Financial Risks of RAC Audits

Cotiviti audits can result in:

  • Large recoupment amounts

  • Extrapolated overpayment demands

  • Cash flow disruption

In severe cases, audits may trigger additional scrutiny from other oversight entities.

How to Respond to a Cotiviti RAC Audit

1. Review the ADR Carefully

Understand:

  • Scope of the audit

  • Documentation requirements

  • Deadlines

2. Gather Complete Documentation

Ensure records include:

  • Physician orders

  • Clinical notes

  • Proof of delivery

  • Billing documentation

3. Conduct Internal Review

Identify potential weaknesses before submission.

4. Submit Timely and Organized Documentation

Late or incomplete submissions result in automatic denials.

5. Prepare for Appeals

If denials occur:

  • Analyze findings

  • Develop appeal strategy

  • Submit strong supporting documentation

Strategies to Reduce RAC Audit Risk

1. Strengthen Documentation Systems

Ensure every claim is supported by:

  • Complete clinical documentation

  • Clear physician orders

  • Accurate delivery records

2. Conduct Routine Internal Audits

Regularly review:

  • Claims

  • Documentation

  • Coding accuracy

3. Train Staff on Compliance

Staff must understand:

  • Medicare billing rules

  • Documentation standards

  • Coverage criteria

4. Monitor Billing Trends

Track:

  • Utilization rates

  • Denial patterns

  • Outlier activity

5. Stay Updated on LCD and NCD Requirements

Ensure compliance with coverage criteria for all billed items.

How RAC Audits Differ From Other Medicare Audits

RAC audits differ from UPIC and MAC audits in that they:

  • Focus on financial recovery

  • Target paid claims

  • Use contingency fee structures

This creates strong incentives for identifying overpayments.

Long-Term Compliance Strategies

To maintain compliance and reduce audit risk:

  • Implement compliance programs

  • Conduct ongoing staff training

  • Maintain accurate documentation

  • Monitor performance metrics

Why RAC Audit Preparation Matters

Failure to prepare can result in:

  • Significant financial losses

  • Increased audit frequency

  • Damage to provider reputation

Proactive compliance reduces risk and improves operational stability.

Final Thoughts

Cotiviti RAC audits represent a major compliance and financial risk for DME and orthotics providers. Understanding audit expectations, maintaining strong documentation, and implementing proactive compliance systems are essential for success.

Providers that prioritize compliance and audit readiness are better positioned to withstand RAC scrutiny and protect their operations.
