Behavioral health billing: A complete guide for mental health providers

Why write an article specifically on behavioral health billing and not just healthcare billing as a whole? Because behavioral health billing is quite simply much more complex than the others; owing to factors such as the coding specifics differing from the ones used in general medical billing; behavioral health services including a variety of treatments (as well as the assessment of health and treatment plans being nuanced and variable); and payer regulations varying wildly based on extenuating factors.

However, as we in the healthcare ecosystem know all too well, proper revenue cycle management is a necessity for a practice to function effectively and efficiently, while serving the healthcare needs of as many potential patients as possible.Presently, this is a tool that is lacking in the behavioral healthcare space – behavioral health claim denial rates run at 15-20% for mental health and substance use disorder services, nearly double the 5-10% average for medical and surgical claims, according to the AMA 2025 Prior Authorization Physician Survey. The reasons are structural: time-based CPT coding with precise minute thresholds, per-session medical necessity documentation requirements, and payer-specific pre-authorization burdens that vary significantly across insurers and states.^[1]

Let us explore the specific challenges faced in handling behavioral health billing:

• Coding Requirements: The CPT (Current Procedural Terminology) codes differ for behavioral health and general health. Without proper coding, submissions cannot be made accurately, and reimbursement cannot be received in a timely manner. There are many CPT codes and expecting behavioral healthcare providers (or their administrative staff) to recall them and note them down without error 100% of the time is a lot to ask. For example,psychotherapy with the patient and/or family member of the patient for 16-37 minutes or 38-52 minutes doesn’t seem like a major difference, but they are noted down differently (CPT code 90832 and 90834 respectively), and the reimbursement received for each varies by a significant enough margin that over time, it would cause a major difference in the provider and the practices financial resources.
• Pre-authorization hurdles: Pre-authorization is a necessity to acquire before providing care, as it ensures that the provider will be reimbursed, and the patient will not be burdened with unforeseen out-of-pocket expenses. This is a tedious task, which asks the provider to submit to the payer a detailed and descriptive layout of the patient’s diagnosis and treatment plan, along with supporting documents.
  Payer regulations: Meeting pre-authorization requirements, coding standards, complying with laws and regulations, timely submission of claims (and handling denial), payer requirement variations are just a few of the many hurdles that need to be crossed by the provider to ensure they receive reimbursement from the payer. Adding to this, the Mental Health Parity and Addiction Equity Act (MHPAEA) requires insurers to cover behavioral health services under terms no more restrictive than comparable medical and surgical benefits. For billing teams, this is relevant when a claim is denied on the basis of medical necessity or service limits – a parity-based appeal citing MHPAEA may succeed where a standard resubmission would not.^[2]
• Uncertainty of treatment plans: Behavioral health treatment varies depending on the patient and thus, it is nigh impossible to create a billing procedure that can be uniformly implemented and followed. A patient suffering from depression brought on by a temporary grievance, for example: a breakup, requires a very different treatment plan compared to a patient suffering from depression due to childhood trauma.

Behavioral health billing involves unique complexities, requiring adherence to specific guidelines to ensure accurate and compliant billing. These guidelines help healthcare providers navigate coding, insurance verification, and reimbursement processes for mental and behavioral health services.

The following guidelines, irrespective of the type of organization or location, must be followed by all organizations:

• Ensure that you are using the correct CPT codes when filing claims for the services given.
• Ensure that that patient’s insurance coverage covers the treatment plan before administering the treatment.
• Obtain pre-authorization if required.
• Provide documentation that is uncorrupted, up-to-date and accurate.
• File claims in the time frame required by the payer.
• Stay up to date with federal and state regulations and meet them.

CMS behavioral health billing guidelines

• While CMS covers a wide range of behavioral health services, all of them MUST be medically necessary (and must be proven as such) for CMS to cover their payment.
• Providers, whether they are medical professionals, such as psychiatrists or nurse practitioners, or they provide other forms of mental health support, such as social workers, are eligible to receive reimbursement.
• Accurate coding, documentation and compliance with regulations are all required necessities.

State-specific Medicaid regulations and coverage

• Medicaid program coverage varies based on state regulations. So, services that might be covered under the regulations of one state, might not be covered under a different one. For example, in New York, licensed social workers and mental health counselors are eligible under Medicaid to receive reimbursement; however, in Florida, the only providers who are eligible for reimbursement under Medicaid are licensed medical professionals, like a psychologist or a psychiatrist.
• Telehealth regulations have experienced wide-spread growth in the years since the Covid-19 pandemic, but as a newly popularized method of treatment, it is still gaining ground and has not been adopted completely across all states.
• Licensing requirements, as well as coding, documentation and mental health parity laws and regulations all have a baseline requirement across the nation, but certain states ask that additional or different requirements be met as well for reimbursement to be given.

Payer-specific billing requirements

• Medicaid and Medicare provide reimbursement based on whether the services rendered are medically necessary and covered under their offerings. The necessary tasks that must be completed (coding, documentation, etc.) vary based on state regulations and the provider’s specifications.
• Private insurances provide reimbursements based on a wider range of factors, such as the patient’s specific insurance plan, along with all the requirements that Medicaid and Medicare also require from providers.
• Behavioral health billing for telehealth is a growing field, with telehealth having expanded significantly since 2020. The billing requirements vary by state and payer, and missing the correct modifier or place of service code is the most common cause of telehealth claim denials. Key requirements for 2026 are:
  • Modifier -95: Required for synchronous audio-video sessions. Must be appended to the CPT code (for example, 90834-95)
  • Modifier -93 (or FQ for Medicare): Required for audio-only sessions. Coverage is more restricted than audio-video – verify with each payer before billing
  • POS 10: Use when the patient connects from home. Reimburses at the non-facility rate, equivalent to an in-office visit
  • POS 02: Use when the patient is at a clinical site. This triggers the lower facility rate
  • Telehealth coverage for behavioral health Medicare beneficiaries has been extended through 2026 and most commercial payers have now adopted permanent coverage^[3]

• 42 CFR Part 2 – SUD billing and confidentiality: For practices treating substance use disorder (SUD) patients, 42 CFR Part 2 imposes stricter confidentiality requirements than HIPAA. SUD treatment records cannot be disclosed to payers without written patient consent that meets 42 CFR Part 2 specifications. For billing purposes, this means the standard HIPAA-compliant release of information process is insufficient for SUD records. Claims submitted for SUD services must be accompanied by a properly executed 42 CFR Part 2 consent form authorizing disclosure to the specific payer. The 2024 amendments to 42 CFR Part 2 aligned some provisions more closely with HIPAA, but the core consent requirements for SUD records remain stricter than general medical billing.

2026 update: The Collaborative Care Management (CoCM) codes 99492, 99493, and 99494 were replaced by G0568, G0569, and G0570 effective January 1, 2026. If your practice provides CoCM services, verify that your billing system has been updated to the new G-codes. Claims submitted with the old 994xx codes will be denied for dates of service on or after January 1, 2026. Additionally, as of January 1, 2024, Licensed Professional Counselors (LPCs) and Licensed Marriage and Family Therapists (LMFTs) became eligible Medicare providers, reimbursed at 75% of the Physician Fee Schedule for covered behavioral health services.^[4]

Choosing the right behavioral health EHR system

Many of the issues in billing rises from human error. The usage of an EHR would eliminate or greatly reduce that risk and ensure the data is accurate. Furthermore, it would save the administrative staff stress and time, which can be allocated towards focusing on patient care.

EHRs can also be a great asset in ensuring that the provider complies with regulatory requirements, as well as coding standards, while implementing validation checks, maintaining data synchronization, and boosting inter-office coordination.

When to consider outsourcing your billing

Billing/Revenue Cycle Management services are, as the name suggests, experts in their field. They can greatly help behavioral health practices by ensuring that the provider’s practices are up-to-date and meets regulation; they can handles claims submission, as well as denial management; the outsourcing of billing would greatly reduce administrative costs, as well as reducing mental burnout for the administrative staff; the proper filing of claims and handling of denials/delays would lead to faster reimbursements, which would result in increased revenue for the provider, while providing more time and resources that can be utilized in providing care.

How AI can improve billing accuracy and claim tracking

While artificial intelligence and its implementation is still a controversial topic in many fields, healthcare (and its adjacent industries) is a field in which AI can undoubtedly be used for good. AI can be used effectively to aggregate a great swath of information (such as claim procession time, claim denial reasons, etc) and provide reports that would give a better understanding of how best to optimize the practice for efficiency.

Building an effective denial management process

Denial management is an unavoidable reality when dealing with behavioral health billing. There are many reasons that a claim can be denied; the main causes for denial are usually:

• The treatment is not considered a necessity for the patient and therefore not covered by the payer.
• Improper or incorrect coding
• Failure to achieve pre-authorization
• Improper or incomplete documentation

Here are some strategies that could be implemented to avoid denials in the future:

• Aggregate the previous denied claims to better understand the reasons behind why they were denied and find recurring issues that can be corrected
• If you choose to do in-house billing, ensure that the billing staff is properly trained (as well as regularly updated on any regulations and practices)
• Ensure that pre-authorization and eligibility are verified before any treatment is administered
• We’ve repeated this many times over the course of this article, but it cannot be reiterated enough the importance of accurate coding and documentation

• Negating or greatly reducing coding and documentation issues affecting reimbursement
• Ease of mind that pre-authorization and insurance verification are handled properly and without burdening the administrative staff
• Centralized bil ling allows for larger practices with multiple locations to ensure that payment is allocated to the locations they are supposed to be sent to
• Data collection becomes seamless and automated, once again removing the possibility of human error causing delays
• Administrative tasks, such as scheduling/re-scheduling or setting up recurring appointments, can be automated easily and conveniently
