6 Essential Steps to Pass a Medicare Audit: The Rehab Therapist’s Guide

For many rehab therapists, the words “Medicare Audit” bring an immediate sense of dread. Audits can disrupt patient care, add hours of extra work, and create fear that even small mistakes might lead to denied Medicare claims or repayment demands. The deadlines are tight, the stakes are high, and the process can feel overwhelming. 

According to the Centers for Medicare & Medicaid Services, documentation must support the therapist’s professional judgment and show that the patient requires the unique skills of a therapist to improve function or prevent deterioration. The reality is, audits aren’t rare. They’re part of Medicare’s ongoing effort to ensure compliance, prevent fraud, and verify medical necessity. Even the most diligent therapists can get tripped up by incomplete notes, missing signatures, or unclear documentation. 

Passing a Medicare audit doesn’t have to feel like a battle. With the right systems in place, you can ensure every note, code, and treatment plan meets compliance standards—without working overtime or second-guessing your documentation. This blog will show you how to survive—and even thrive—when Medicare comes knocking, with practical strategies that make compliance less of a scramble and more of a daily habit.

Understanding Medicare Audits in Rehab Therapy

What Triggers a Medicare Audit for PTs, OTs, and SLPs

Medicare audits can be triggered for a variety of reasons—some random, others tied to specific billing practices or documentation patterns. High utilization rates, frequent use of certain CPT codes, or unusually high reimbursement amounts compared to peers can raise red flags. Even consistent treatment beyond the typical duration for a condition can prompt a review if medical necessity isn’t clearly documented (CMS MLN905365, p.5–6).

The CMS manual notes: “Documentation must support the therapist’s professional judgment and show that the patient requires the unique skills of a therapist to improve function or prevent deterioration.” (p.6)

Audits may also be initiated due to patient complaints, whistleblower reports, or inconsistencies found during data analysis by Medicare contractors. In many cases, it’s not about intentional wrongdoing. Simple errors like incomplete progress notes, missing signatures, or vague treatment descriptions can invite scrutiny. The safest approach is to assume every claim could be reviewed and make compliance a part of your daily workflow.

The Most Common Types of Audits (CERT, RAC, TPE)

CERT (Comprehensive Error Rate Testing) audits are designed to measure improper payment rates by randomly sampling submitted claims. They check for compliance with coverage, coding, and billing requirements. While random, failing a CERT audit can lead to repayment demands and future scrutiny.

RAC (Recovery Audit Contractor) audits focus on identifying and correcting improper payments—whether overpayments or underpayments. These are often post-payment audits that require you to submit documentation after services are rendered, and they can cover claims from several years back. 

TPE (Targeted Probe and Educate) audits, on the other hand, focus on providers with high claim error rates or unusual billing patterns. TPEs are unique because they pair medical review with education—if errors are found, Medicare offers feedback and allows you to correct your processes before the next round. Understanding these audit types helps you prepare for the unique demands of each and respond appropriately without panic. According to CMS, “TPE reviews include individualized education and allow the provider to correct errors before subsequent review cycles.” (p.12)

Pain Points Therapists Face During Audits

When an audit notice arrives, the stress is real. It involves pulling years’ worth of records, tracking down missing signatures, and juggling reorganized schedules that disrupts patient care and adds emotional strain. Many practices struggle under the pressure of tight deadlines and disorganized archives.

CMS emphasizes that certain compliance lapses are easily avoidable. For example: “The plan of care must be certified by a physician or NPP within 30 days of the initial therapy treatment and recertified at least every 90 days.” (p.8) Missing these deadlines is one of the most common audit failures in outpatient rehab.

Moreover, audit anxiety intensifies when compliance rules shift or remain unclear. Even small documentation lapses—missing objective data or inconsistent SOAP notes—can result in serious penalties. Incomplete charts and manual records increase the risk of audit failure and negatively impact your team’s morale and workflow.

Step-by-Step Guide on How To Pass Your Medicare Audit

Step 1: Keep Documentation Audit-Ready at All Times

Document sessions in real-time or by end-of-day to prevent gaps. Notes must clearly reflect medical necessity, measurable goals, and progress, and include objective functional outcomes (p.5–6). Include objective, functional outcome data whenever possible—this is your first line of defense in an audit.

Step 2: Know the Medicare Guidelines Inside and Out

Familiarize yourself thoroughly with CMS’ therapy documentation rules—treatment caps, certification requirements, and recertification protocols. Being proactive with annual updates ensures your documentation remains in line with current standards.

• Plan of care certification within 30 days (p.8)
• Recertification at least every 90 days (p.8)
• Progress reports every 10 treatment days or 30 calendar days (p.9)

Step 3: Use Compliance Checklists and Internal Audits

Regular internal audits guard against errors before an external review. Create daily, weekly, or monthly checklists, and incorporate peer reviews into your workflow. Mock audits reduce risk and teach your team what auditors look for. Ensure objective measures and updated goals appear in every progress report (p.9).

Step 4: Organize Your Records for Quick Access

Keep plans of care, treatment notes, and progress records stored together. Medicare requires: “All documentation be retained in the patient’s medical record for at least 6 years from the date of service.” (p.13)

A searchable EMR with uniform formatting makes audit prep simple. Consolidate signed plans of care, re-evaluations, treatment notes, and progress records in one digital system—retrieval should require minutes, not hours.

Step 5: Leverage Technology to Reduce Risk

Use EMRs or AI tools like ScribePT to monitor compliance with CMS’ required documentation elements—including date, signature, credentials, treatment details, and time logs (p.5–6).

This will help you monitor clinical notes in real-time, flag missing documentation elements, suggest appropriate codes, and automate reminders to keep your notes compliant. This tech improves accuracy and saves documentation time—giving you peace of mind and better audit readiness.

Step 6: Prepare Your Team Before an Audit Notice Arrives

Train your staff on audit expectationsTrain staff on documentation timelines and how to submit additional records promptly when requested (p.12–13). Assign clear roles for when an audit letter comes in and keep your regional Medicare contractor’s contact information handy. A coordinated team response turns chaos into clarity.
