As Transcranial Magnetic Stimulation (TMS) therapy becomes an increasingly popular treatment option for patients with Major Depressive Disorder (MDD), healthcare providers are facing new challenges in billing for these services.
TMS is a specialized procedure that requires careful coding, accurate documentation, and proper billing to ensure timely reimbursement. Unfortunately, billing errors are common and can significantly impact the revenue cycle of practices offering TMS therapy.
Understanding the most common billing errors associated with TMS therapy is the first step in preventing costly disruptions to your revenue cycle. So, let’s break down the 5 key TMS billing mistakes that often occur and their impact on your revenue cycle
1. Failure to Obtain Pre-Authorization
TMS therapy often requires prior authorization (PA) from insurance companies before treatment begins. Without the correct PA, your practice risks claim denials. Even if a patient has insurance coverage for TMS, failing to follow the necessary pre-authorization steps can delay reimbursement.
Impact on Revenue Cycle: If you proceed with TMS therapy without prior authorization, insurance companies will deny payment, and you’ll be left with the task of appealing the denial. This process can take weeks or even months, delaying payments and requiring additional administrative resources. In some cases, if the patient cannot pay for the treatment upfront, this can result in lost revenue.
2. Incorrect CPT and ICD-10 Coding
The cornerstone of TMS billing is accurate coding. Both CPT codes and ICD-10 codes must be selected carefully to match the specific service provided and the patient’s diagnosis.
- CPT Codes: The primary CPT code for TMS therapy is 90867, which is used for the initial TMS session. For subsequent sessions, CPT Code 90868 is used. Billing for the administration of TMS requires these codes, along with additional codes for physician oversight and monitoring.
- ICD-10 Codes: Common diagnosis codes for TMS therapy typically include F32.9 (Major Depressive Disorder, single episode, unspecified) and F33.9 (Major Depressive Disorder, recurrent, unspecified). Accurate ICD-10 coding is necessary to demonstrate the medical necessity of TMS treatment.
Impact on Revenue Cycle: If you fail to use the correct CPT or ICD-10 codes, your claim may be rejected or delayed. Inaccurate codes may lead to a situation where the insurance company deems the treatment not medically necessary or incorrectly billed. This can result in denials and a significant delay in payments, impacting cash flow and causing your practice to lose revenue.
3. Not Using the Correct Modifiers
Modifiers are used in medical billing to indicate that a service or procedure has been altered in some way but not changed in its definition. For TMS therapy, using the correct modifiers is essential for accurate reimbursement.
For example, Modifier 25 might be needed if a separate, significant, and identifiable evaluation and management service is performed on the same day as the TMS therapy. Similarly, Modifier 59 may be necessary to indicate that services are distinct or separate from other procedures provided on the same day.
Impact on Revenue Cycle: Failing to apply the correct modifiers can result in underpayment or denial. Insurance companies may assume that multiple services are being bundled together incorrectly, leading to inaccurate reimbursement. This will not only delay payment but could also result in additional administrative work to resubmit claims.
4. Improper Documentation of Medical Necessity
One of the key requirements for TMS therapy reimbursement is demonstrating that the treatment is medically necessary. For many insurance providers, this means documenting that the patient has not responded to other forms of treatment (e.g., antidepressants or therapy).
Without detailed documentation showing that the patient has failed traditional treatments or has treatment-resistant depression, the claim may be denied. This documentation should include the patient’s medical history, progress notes, treatment attempts, and physician recommendations.
Impact on Revenue Cycle: Insufficient documentation can lead to claim denials for lack of medical necessity. Without the proper support, your practice may not get reimbursed for services rendered, and patients may be left responsible for the full cost. This places a burden on your billing department and can disrupt your revenue cycle.
5. Inadequate Follow-Up on Denied Claims
Denial management is a critical part of the billing process, and many practices make the mistake of not following up on denied claims on time. A claim denial can occur for various reasons: incorrect coding, lack of prior authorization, or insufficient documentation. If left unaddressed, these denials will pile up, leaving your practice with a significant amount of lost revenue.
Impact on Revenue Cycle: A failure to follow up on denials within the allotted timeframe (usually 30-60 days) means the claim may be permanently rejected. This can cause your practice to lose out on revenue that is rightfully owed. Proactive denial management is essential to prevent this from happening and ensure payments are processed as quickly as possible.
Best Practices to Prevent TMS Billing Errors
As you have understood how TMS billing errors can impact your revenue cycle, it’s time to implement strategies to reduce mistakes and streamline your revenue cycle management.
Here are some best practices to follow:
1. Invest in Proper Training for Your Billing Team
TMS billing requires specialized knowledge. Make sure your billing team is well-trained in the specific codes, documentation requirements, and insurance policies related to TMS therapy. Consider providing ongoing education to keep up with updates and changes in coding guidelines.
2. Double-Check Your Codes
Before submitting any claims, make sure to double-check both the CPT and ICD-10 codes. Use an electronic health record (EHR) system that is integrated with coding software to reduce human error. This system can help verify that the correct codes are used and that the claim is properly formatted for submission.
3. Establish a Robust Pre-Authorization Process
Create a streamlined process for obtaining pre-authorization from insurance companies before administering TMS therapy. This will help ensure that claims are not denied due to a lack of pre-approval. Be diligent about checking each patient’s insurance requirements and following up promptly to ensure that authorization is granted.
4. Maintain Thorough Documentation
Document every step of the patient’s treatment process, including their diagnosis, the treatments they have already tried, and the medical necessity for TMS therapy. A well-documented case will reduce the likelihood of denials based on insufficient medical necessity.
5. Regularly Review Denied Claims
Establish a routine for reviewing denied claims and addressing the issues that caused the denial. Don’t wait for too long before resubmitting the claim. If necessary, consider hiring a dedicated staff member to manage denials and appeals, ensuring that your practice gets paid for services rendered.
Conclusion
TMS therapy is a promising treatment for patients with treatment-resistant depression, but it comes with its own set of billing challenges. Billing errors—such as incorrect coding, lack of pre-authorization, and inadequate documentation—can negatively impact your revenue cycle. By following best practices and ensuring your billing team is properly trained, you can minimize these errors and improve cash flow.
