According to the Centers for Disease Control and Prevention (CDC), 23% or 1 in every 5 adults in the US is fighting with a mental illness of some sort, and 20% or 1 in 5 adolescents aged between 12 and 17 are diagnosed with a mental or behavioral condition.
With 6% or 1 in 18 people affected by serious mental conditions like schizophrenia, bipolar disorder, or major depression, and mental healthcare becoming more accessible, clinics and behavioral health centers are seeing a steady influx of patients seeking mental healthcare.
What is Mental Health Billing?
The process of documenting, coding, submitting, and collecting payment against mental health services provided by mental health practitioners is known as mental health billing. The services provided under this comprehensive specialty include, but aren’t limited to, therapy sessions, psychiatric evaluations, and medication management.
An important aspect of mental health billing is that it involves both in-person and virtual sessions, i.e., telehealth. Mental health billing is more complicated compared to other specialties because of interactions with federally backed programs like Medicare and Medicaid, commercial payors, and self-pay patients.
One primary challenge in this specialty faced by mental health billers and coders is the medical classification of services. Mental health conditions are identified and classified using the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). It is a standard guide used by professionals to diagnose and categorize different psychiatric disorders.
To ensure error-free billing and deserved revenue generation against the services, billing specialists must ensure precise coding of diagnoses and treatment procedures rendered.
Mental Health Billing: Lucrative but Challenging
The rise in patient footfall has put immense pressure on mental health clinics and private practices, significantly increasing the workload on clinicians and billing experts. Although lucrative, a higher claim volume that is complex to handle differentiates mental health billing from other specialties.
More importantly, mental health specialists, psychologists, and psychiatrists focus on providing exceptional patient care and support. They specialize in therapy sessions, medication management, crisis interventions, and evidence-based treatments for depression and anxiety
They aren’t trained to handle mental health billing conundrums like error-free documentation, appending precise CPT and ICD-10 codes, maintaining CMS compliance, ensuring prior authorization, and managing claim denials. So, handling these time-consuming and technical administrative tasks on their own can result in loss of energy, effort, and revenue.
Common CPT Codes Used for Mental Health Billing in 2026
Here are some of the common codes that billers and coders specializing in behavioral health must be aware of in 2026.
90791: Psychiatric diagnostic evaluation without medical services.
90792: Psychiatric diagnostic evaluation with medical services.
90832: Individual psychotherapy, 30 minutes (16-37 min).
90834: Individual psychotherapy, 45 minutes (38-52 min).
90837: Individual psychotherapy, 60 minutes (53+ min).
90846: Family psychotherapy without the patient present.
90847: Family psychotherapy with the patient present.

99484: General Behavioral Health Integration (BHI) care management.
90832, 90834, and 90837 are time-based CPT codes with clear minute ranges. To use the time-based codes in the claim and receive reimbursements, it is important to meet minimum time requirement explained in the Supanote.
90875 is an add-on which is used to describe interactive complexity in the case of non-verbal patients or when the communication is difficult.
Codes 99202-99215 are Evaluation and Management (E/M) codes. When a psychotherapist or mental health provider performs both an E/M service and psychotherapy during the same visit, add-on codes 90833, 90836, or 90838 are billed along with the appropriate E/M code.

Who Is Eligible to Bill Medicare for Mental Health Services?
If you plan to bill Medicare for mental health services such as diagnostic evaluations, therapy, or SBIRT services, you must be an approved Medicare Part B provider. Here’s a list of eligible providers who are authorized to bill for these mental health services.
- Psychiatrists
- Psychologists
- Clinical Social Workers
- Licensed Professional Counselors
- Nurse Practitioners
Step-By-Step Process of Medical Billing for Mental Health
Insurance Verification and Patient Responsibility
The process starts with checking the patient’s insurance coverage. You must confirm if their plan includes mental health services and what portion they are responsible for, such as copays or deductibles.
All insurance plans don’t cover every service. It is worth remembering that some policies cover mental health only and include short-term therapy. However, some plans cover psychiatric evaluations and medication management. Verifying this early helps avoid billing surprises and claim issues later.
Assigning Precise Diagnosis and Procedure Codes
Once coverage is clear, the next step is coding the services correctly. This means selecting the right diagnosis and CPT codes based on the patient’s condition and the type of session provided. Coding must reflect what actually happened during the visit. Even small mistakes here can lead to denials or delays, so accuracy is critical.
Claim Submission to the Insurance Company
After coding, the claim is sent to the insurance company for review. The claim includes patient details, provider information, and the services performed. The insurer checks everything and decides how much to reimburse. Once approved, payment is issued, and any remaining balance becomes the patient’s responsibility.
Payment Posting and Patient Billing
Once the insurance company processes the claim, the payment is sent to the provider. This payment is then recorded in the billing system, a process known as payment posting. If there’s any remaining balance, such as copays, deductibles, or non-covered services, the patient is billed. Keeping track of payments properly helps maintain accurate financial records and prevents revenue loss.
Handling Denials and Follow-Up
Not every claim gets approved on the first attempt. Like every other specialty, some claims in behavioral health billing may be denied due to coding errors, missing information, or coverage issues. When this happens, the billing team reviews the denial, fixes the problem, and resubmits the claim. Timely follow-up is important. The longer a denied claim sits unresolved, the harder it becomes to recover the payment.
Why are Mental Health Billing Services Challenging?
There are multiple reasons that make mental health billing services difficult to handle. Unlike general billing, behavioral health billing involves a focus on recurring, long-term therapy sessions. Biller and coders specializing in this unique specialty deal with frequently changing time-based CPT/ICD codes and strict documentation requirements.
They have to continuously navigate through complex and restrictive behavioral health insurance coverages. Ensuring strict data confidentiality and compliance with HIPAA and CMS is another challenge they keep up with. Other challenges involved are high denial rates and stringent prior authorization rules.
Let’s now briefly explain some of the complexities involved:
High Claim Denial Rates
Due to the complexities involved, behavioral health claims are frequently denied, resulting in loss of substantial revenue every year. The main denial reasons can be unbundling of codes, inaccurate patient or provider data, inability to process technical claims, and not using precise codes for medical classification.
Time-based CPT and ICD-10 codes
The dependence on specific, time-based CPT and ICD-10 codes makes mental health billing an intricate one among all specialties. Based on session duration, i.e., 30, 45, or 60+ minutes, experts must carefully use codes like 90832 or 90837 instead of one-off codes. Missing even a modifier or not entering the exact diagnostic code results in denials or payment delays.
Detailed Documentation
Billers must justify the session times and the medical necessity of behavioral health therapy within the documentation. Documentation must include treatment objectives, patient improvement, effects of the therapy, and the type of therapy provided. These subjective requirements differentiate it from physical procedures.
Patient Confusion
Improper billing can lead to patient confusion and payment issues. They don’t want last-minute surprises in the form of hefty bills. The patient-provider relationship may be affected when they have to pay for services they think are covered under their policy plan. It leads to reputational damage for the mental care provider like Psychiatrist or Psychologist.
Complexities in Mental Health Insurance
Insurance companies often outsource mental health benefits to third-party administrators. This means providers may have to follow separate and stricter rules, such as obtaining special pre-authorizations before delivering certain services.
Increase in Telehealth Sessions
With the growth of telehealth, it is important to understand each insurance company’s rules for virtual sessions. Behavioral health billing services track these requirements and make sure every session, whether online or in person, is billed accurately and in compliance with payor guidelines.
Use of Specific Modifiers
The use of HCPCS modifiers makes or breaks a claim in mental health billing. If the medical coders are not aware of the significance of specific modifiers, like using 95 for telehealth, chances are they’ll lose payment due to a denial.
Strict Compliance Standards
Mental health billing, including time-based sessions, is sensitive on account of the time involved, data security, and other types of sensitive information involved. If the data security isn’t considered integral, or you don’t meet compliance regulations, you may have to face denials and even legal penalties.
Variable Reimbursement
Due to variable reimbursements, often lower than those in physical specialties, mental health billing services require careful management to ensure accurate and efficient claims submission and consistent revenue.
Administrative Burden
Mental health billing, owing to the intricacies and nuances involved, is considered complex, tricky, and time-consuming. So, doing it in-house often leads to provider burnout, errors caused by assisting staff, and a focus shift from primary tasks.
Medical Billing for Mental Health Vs Regular Medical Billing
Mental health billing services are considered more intricate, demanding, and complex as compared to billing for other specialties. Medical billing for mental health involves time-based services, strict documentation requirements, and coding for psychiatric diagnoses and therapy sessions.
On the other hand, medical billing for physical conditions is based on procedure-based services like exams, surgeries, diagnostic tests, or labs. Here, the RCM specialists follow standardized billing procedures, which aren’t prevalent in behavioral health billing.
| Aspect | Mental Health Billing | Regular Medical Billing |
| Coding System | Uses DSM-5 for diagnosis reference and ICD-10 for billing, along with CPT codes specific to psychotherapy and psychiatric services. | Primarily uses ICD-10 and CPT codes focused on physical procedures, exams, and treatments. |
| Service Structure | Often time-based, such as 30, 45, or 60-minute therapy sessions. | Mostly procedure-based, such as lab tests, surgeries, or physical examinations. |
| Authorization Requirements | More likely to require prior authorization, especially for therapy sessions and ongoing treatment. | Authorization is required mainly for major procedures, imaging, or surgeries. |
| Documentation Needs | Requires detailed session notes, treatment plans, and proof of medical necessity. | Focuses on clinical findings, test results, and procedure documentation. |
| Reimbursement Rates | Often lower and more variable depending on payer and service type. | Generally more consistent, especially for standardized procedures. |
| Claim Complexity | More complex due to behavioral health carve-outs and third-party administrators. | Typically more straightforward with fewer carve-outs. |
| Common Providers | Psychiatrists, psychologists, therapists, counselors, and behavioral health specialists. | Physicians, surgeons, specialists, hospitals, and general practitioners. |
