Understanding TMS Billing: Streamlining Transcranial Magnetic Stimulation Reimbursement Processes

Transcranial Magnetic Stimulation (TMS) has emerged as a promising non-invasive treatment option for various psychiatric and neurological disorders, including depression, obsessive-compulsive disorder, and migraines. As the popularity and utilization of TMS therapy continue to grow, healthcare providers must navigate the complex world of billing and reimbursement to ensure the financial viability of offering this innovative treatment. This article aims to provide an in-depth understanding of TMS billing, including its intricacies, challenges, and best practices.

The Basics of TMS Billing:

TMS billing encompasses the entire process of submitting claims for reimbursement from insurance companies or government payers. It involves several key components, including coding, documentation, claim submission, and reimbursement management. To facilitate accurate billing, healthcare providers must familiarize themselves with the specific billing codes associated with TMS procedures, such as Current Procedural Terminology (CPT) codes and Healthcare Common Procedure Coding System (HCPCS) codes.

Importance of billing and reimbursement in TMS therapy

Here we will explore the significance of billing and reimbursement in TMS therapy and highlight the benefits it offers to both providers and patients.

Financial Viability:

  • TMS therapy involves significant investments, such as the purchase or rental of TMS devices and the cost of specialized staff training. Proper billing and reimbursement processes ensure that providers can cover these expenses and maintain financial viability.
  • Accurate billing and timely reimbursement help providers manage operational costs, such as staffing, maintenance, and overhead expenses associated with offering TMS therapy.

Accessibility and Affordability:

  • Billing and reimbursement play a crucial role in ensuring that TMS therapy remains accessible and affordable to patients. Reimbursement allows providers to offer TMS services at a reasonable cost, reducing the financial burden on patients seeking this innovative treatment.
  • Adequate reimbursement encourages healthcare providers to continue offering TMS therapy, expanding access to a larger patient population. This, in turn, improves patient outcomes by increasing the availability of this effective treatment option.

Insurance Coverage:

  • Billing and reimbursement processes are directly tied to insurance coverage for TMS therapy. Insurance coverage varies across different providers, plans, and regions. Proper billing practices help providers navigate the complexities of insurance coverage and ensure appropriate reimbursement for TMS procedures.
  • Understanding insurance policies, pre-authorization requirements, and documentation guidelines is crucial to obtain the maximum allowable reimbursement for TMS therapy. Effective billing practices help providers optimize the utilization of insurance benefits, minimizing the out-of-pocket expenses for patients.

Compliance with Regulations:

  • Billing and reimbursement in TMS therapy must comply with relevant regulations, guidelines, and coding standards. Proper adherence to these standards ensures ethical and legal practices in healthcare billing.
  • Compliance with regulations also minimizes the risk of audits, penalties, and legal issues. It is essential for providers to stay updated with coding and billing requirements to ensure compliance and avoid potential financial and reputational consequences.

Revenue Cycle Management:

  • Efficient billing and reimbursement processes contribute to streamlined revenue cycle management. Accurate documentation, coding, and timely claim submission improve the speed of reimbursement and reduce claim denials or delays.
  • Effective revenue cycle management enhances the overall financial health of healthcare organizations. It allows providers to allocate resources efficiently, invest in technology and training, and continue providing quality care to patients.

CPT and HCPCS Codes for TMS:

Two common CPT codes used for TMS are 90867 and 90868. CPT code 90867 represents a session of TMS therapy without neuronavigation, while 90868 denotes a session with neuronavigation. These codes encompass the actual administration of TMS treatment. It is essential to document the specific number of pulses delivered during each session to ensure accurate coding.

HCPCS codes are also crucial in TMS billing. The most commonly used HCPCS code for TMS is S4981, which covers the rental or purchase of the TMS device. This code should be accompanied by appropriate documentation, including the start and end dates of the rental period or the purchase invoice.

Challenges in TMS Billing:

TMS billing presents certain challenges that healthcare providers must navigate effectively. Some of the key challenges include:

  • Insurance Coverage: While TMS is an FDA-approved treatment for depression, insurance coverage may vary. Providers must verify the patient’s insurance coverage and determine the specific requirements, pre-authorization criteria, and documentation needed for reimbursement.
  • Documentation: Thorough and accurate documentation is crucial for successful TMS billing. Providers must document the patient’s diagnosis, treatment plan, treatment parameters, and progress notes to support medical necessity and reimbursement claims.
  • Prior Authorization: Many insurance companies require prior authorization before approving TMS treatment. Providers should ensure timely submission of prior authorization requests and provide the necessary supporting documentation, including medical records and a letter of medical necessity.
  • Claims Denials and Appeals: Despite careful billing practices, claims denials may occur. In such cases, providers must be prepared to navigate the appeals process, which involves submitting additional documentation and appealing the decision within the stipulated timeframe.

Best Practices in TMS Billing:

To optimize the reimbursement process and minimize billing challenges, healthcare providers should adopt the following best practices:

  • Verify Insurance Coverage: Before initiating TMS treatment, providers should verify the patient’s insurance coverage and understand the specific requirements for reimbursement, including pre-authorization criteria and documentation guidelines.
  • Comprehensive Documentation: Accurate and detailed documentation is crucial for successful TMS billing. Providers should document the patient’s diagnosis, treatment plan, session details, progress notes, and any additional information required by payers.
  • Timely Prior Authorization: Providers should submit prior authorization requests promptly, ensuring they include all necessary supporting documentation. Following up with insurance companies and providing additional information, if required, can expedite the approval process.
  • Billing Software and Expertise: Utilizing specialized billing software can streamline the billing process and reduce errors. Providers should also consider partnering with billing experts or consultants who have expertise in TMS reimbursement to ensure compliance and maximize reimbursement.
  • Ongoing Training and Education: Billing and coding practices are subject to frequent updates and changes. It is crucial for healthcare providers and their billing staff to stay updated with the latest coding guidelines, payer policies, and regulations through regular training and education.


Efficient TMS billing is essential for healthcare providers to offer this innovative treatment while maintaining financial viability. Understanding the specific coding requirements, documenting accurately, navigating prior authorization, and addressing claims denials are vital aspects of successful TMS billing.
