Avoiding Therapy Claim Denials: Common CPT Code Mistakes & Solutions
Avoiding therapy claim denials starts with accurate coding and documentation. Learn how to prevent common CPT coding mistakes, improve claim approvals, and streamline reimbursement for therapy services. Discover best practices, appeal strategies, and how HelloNote EMR can help reduce denials and maximize revenue.

Introduction
Dealing with claim denials is a struggle no therapy practice wants to face, but it’s a reality for many. Whether you’re providing physical therapy, occupational therapy, or speech-language services, coding errors can lead to costly denials that impact your practice’s bottom line. These denials not only cause delays in reimbursement but also create financial strain, disrupting the day-to-day operations of your clinic.
The financial impact can be significant, leading to lost revenue, increased administrative workload, and strained relationships with patients. That’s why it’s crucial to minimize claim denials by avoiding common CPT code mistakes. With the right approach to coding and documentation, you can reduce denials and improve the financial health of your practice.
This guide explores common CPT coding errors, preventative strategies, emerging billing challenges, and how to appeal denied claims effectively.
Why Understanding CPT Code Denials is Critical
Each claim denial represents more than just an administrative hiccup. It translates to delayed payments, lost revenue, and an increased burden on administrative resources. When denials pile up, it puts the financial health of the practice at risk, forcing staff to spend valuable time correcting claims and resubmitting them.
Key Consequences of Claim Denials:
Disruptions in cash flow, impacting staff salaries, equipment, and facility costs.
Increased administrative workload, delaying care for new and existing patients.
Potential limitations on patient services due to financial pressures.
Understanding why denials happen and how to proactively prevent them is essential for maintaining the financial stability of your practice.
Top Reasons for Denials and How to Avoid Them
Below are common reasons therapy claims get denied and how to prevent these issues before they impact reimbursement.
1. Medical Necessity Denials
Why It Happens: Insurers challenge whether a service is medically necessary, especially for modalities like ultrasound therapy (97035).
How to Prevent It:
Include a clear clinical justification linking treatment to the patient’s condition.
Document functional goals and expected improvements tied to the therapy.
Example: Instead of writing “Patient received ultrasound therapy,” document “Ultrasound therapy applied to reduce inflammation and improve mobility in post-operative knee recovery.”
2. Inadequate Documentation
Why It Happens: Notes lack measurable progress, functional outcomes, or justification for continued treatment.
How to Prevent It:
Ensure every session note includes treatment goals, patient progress, and functional impact.
Example: Instead of writing “Patient did strengthening exercises,” document “Patient performed 3 sets of 10 reps of resisted shoulder abduction with a theraband to improve strength for independent dressing.”
3. Duplicate Billing & Overlapping Codes
Why It Happens: Services like self-care training (97535) and therapeutic activities (97530) may overlap, leading to denied claims.
How to Prevent It:
Use Modifier 59 when billing 97110 (therapeutic exercise) and 97530 (therapeutic activity) on the same day.
Differentiate codes with clear documentation explaining their distinct purposes.
Example: “97110 used for resistance exercises to build knee strength, while 97530 focused on functional mobility with stair climbing.”
4. Exceeding Frequency Limitations
Why It Happens: Certain codes, like re-evaluations (97164), get flagged when billed too frequently without justification.
How to Prevent It:
Verify payer-specific limits before billing.
Justify re-evaluations with clear evidence of progress or treatment modifications.
Example: “Re-evaluation required due to decreased range of motion despite previous intervention, requiring an updated treatment plan.”
5. Incorrect Use of CPT Codes for Emerging Therapies
Why It Happens: Laser therapy (S8948), shockwave therapy (0101T), and other newer modalities are often considered experimental by insurance providers.
How to Prevent It:
Confirm coverage before providing specialized treatments.
Document why previous treatments failed and why the new modality is necessary.
Obtain pre-authorization when possible.
How to Appeal Denied Claims
If a claim is denied, don’t give up—many denials can be reversed with a strong appeal. Here’s how:
Step 1: Identify the Reason for Denial
Review the Explanation of Benefits (EOB) to determine the reason.
Identify missing documentation, incorrect coding, or payer policy conflicts.
Step 2: Gather Supporting Documentation
Include detailed clinical notes, prior authorizations, and payer guidelines.
Provide a letter of medical necessity, especially for treatments flagged as investigational.
Step 3: Submit an Appeal Within the Deadline
Most insurance companies allow 30-60 days for appeal submissions.
Contact the payer directly for additional clarification if needed.
Step 4: Track & Follow Up
Keep detailed records of all submitted appeals.
Follow up regularly to ensure timely resolution.
