According to estimations, more than one in five adult Americans suffers from a mental disease. A lot of those who suffer from mental health problems, such as Obsessive-Compulsive Disorder (OCD) and Major Depressive Disorder (MDD), are not satisfied with the results of conventional psychiatry and pharmacology. Hence, transcranial magnetic stimulation (TMS) is becoming a more widespread solution for chronic mental health problems.
A therapist may bill this non-invasive procedure under CPT code 90869. So, if you want to learn the best uses of this code and related billing and reimbursement guidelines, continue reading this blog.
CPT Code 90869 – Description
In medical billing, CPT code 90869 refers to a psychiatric treatment procedure, TMS, which is an outpatient procedure and involves the use of gentle magnetic pulses.
90869 is officially defined as:
“Subsequent motor threshold re-determination with delivery and management during a course of TMS therapy.”
In simple terms, the TMS therapy uses a magnet to produce electric pulses that stimulate brain nerve cells. During this procedure, the provider then redetermines the minimum intensity of electrical pulses required to elicit the desired response in brain activity. Based on his findings, he administers and oversees the therapy. He carries out the treatment to cure depression in a patient who is not improving with medicine or other therapies.
The intensity may vary based on the patient’s progress, his response to treatment, physical or neurological changes, and other needs for equipment adjustment. The proper adjustment of the motor threshold ensures safe, efficient stimulation and optimal therapeutic outcomes.
Scenarios Where CPT Code 90869 is Applicable
Let’s talk about a few real-world situations to clearly understand the practical uses of CPT code 90960.
Unimproved Symptoms of Depression
Suppose a 42-year-old patient was diagnosed with depression six months ago. After four months, his depression symptoms stopped improving and responding to therapies and medications. Since the psychiatrist had tried multiple antidepressant medications, his last option was to opt for a 2-month course of TMS therapy.
In the first three weeks, the patient reported improved mood, better sleep, and increased energy levels. However, in the next session, the patient stopped responding to the treatment. This clinical trigger prompted the psychiatrist to change the stimulation settings, which were no longer optimal for the patient.
In this case, CPT code 90869 must be billed because the service included a motor threshold re-determination during an ongoing treatment course.
Unexpected Side Effects of TMS Sessions
In another case, a 50-year-old patient has been successfully receiving TMS sessions for chronic depression. When the patient arrives for his next session, he reports that he experienced slight headaches and facial twitching after his last session.
Hence, before beginning with the session, the psychiatrist performs a motor threshold re-determination to ensure patient safety and therapy efficacy. The evaluation indicates that the patient’s level of stimulation has to be changed. CPT code 90869 is an appropriate code to bill in this scenario.
Poor Response to TMS
Let’s say a patient who was suffering from severe depression was getting treatment through TMS sessions. But even after attending regular multiple sessions, he did not show any signs of improvement.
Hence, his psychiatrist performs clinical evaluations, which indicate that the current treatment parameters may not be producing the desired therapeutic effect. As a result, the psychiatrist performs a motor threshold re-assessment to determine whether treatment intensity should be modified. He then continues with the TMS sessions after adjusting the stimulation settings based on the new measurements.
To bill these services, CPT code 90869 must be applied to the billing claims.
Applicable Modifiers for CPT Code 90869
You may apply the following modifier with the CPT code 90869.
Modifier 59
Modifier 59 is used to represent distinct procedural services provided during the same session as the primary medical procedure. It indicates that a procedure or service was distinct or independent from other non-E/M services performed on the same day.
However, you must study the rules stated in the National Correct Coding Initiative (NCCI) edits before appending this modifier and unbundling the two services.
CPT Code 90869 – Billing & Reimbursement Guidelines
Even a slight error in medical claims can cause major financial loss to healthcare professionals and practices. To ensure that you are correctly billing the CPT code 90869, follow these billing and reimbursement guidelines.
Submit Detailed Documentation
The way you record your services has a big impact on how successfully and accurately you are reimbursed. Your documentation must demonstrate to the insurance payers that the procedure was medically necessary. If not, you will have to deal with claims audits, delays, or denials because of unclear or missing documentation.
Your complete documentation for CPT code 90869 should include:
- TMS treatment parameters used for each session, including the stimulation site, percentage of motor threshold, the frequency of stimulation, the number of pulses delivered, and the total treatment time.
- Patient’s reaction before, during, and after the treatment session.
- Patient’s current clinical symptoms.
- Mention the number of sessions.
- Details of the supervising physician.
- Provider interpretation and treatment plan changes.
- Reason for re-determining motor threshold (e.g., changes in symptoms or treatment response).
- Details of motor threshold testing methodology.
- Updated treatment parameters and coil positioning.
- Patient consent and tolerability information.
- Signature of a qualified provider performing the service.
Understand the Bundling Rule
Do not report CPT code 90869 with 90867 or 90868 on the same day, because it covers both the motor threshold re-determination and treatment delivery services.
Obtain Prior Authorization
Most payers require prior authorization before they reimburse for TMS therapy sessions. Hence, ensure that you have authorization and do not go over the allotted number of sessions.
Furthermore, the payer may reject the payment if prior authorization was not obtained, regardless of medical need.
Final Words
Billing CPT code 90869 for TMS services becomes simple if you follow the best practices we have discussed in our detailed blog.
However, if you still cannot overcome billing challenges, you can opt for TMS billing services from a reputable company, such as MediBillMD. Their knowledgeable staff is well-versed in payer policy, modifiers, and TMS-exclusive coding. Hence, the specialists can help mental health practitioners focus on delivering high-quality care.
