6 tips for mental and behavioral health billing
Mental and Behavioral health billing is a uniquely challenging endeavor. It has additional challenges on top of what you face in billing for other medical specialties. Limited staff, limited time, unbundling, and pre-authorization are problem areas shared between the two healthcare types.
However, unlike medical specialties, mental health treatment is frequently ill-defined. A patient who comes into an office for a routine physical check-up will receive standardized care. Weight and height measurements, blood pressure checks, and heartbeat monitors are homogenous. As a result, billing is relatively repeatable from client to client.
Unfortunately, this same consistency does not apply to mental health. Each treatment plan varies with session length, therapeutic approach, age, and client willingness. So, behavioral health billers must be more diligent to avoid denials and get maximum reimbursements.
Here are six tips for mental and behavioral health billing.
Maintain Accurate Documentation
Ensure that your clients’ records are up to date. These records should include personal data, insurance details, and medical history/goals. Update your client records at least once a year. Consider establishing an online system where consumers can verify their information before coming to an appointment.
Document your discussions with payer representatives. Note the time of conversation, their name, and what information they provided. This habit prevents confusion and holds payers accountable for miscommunication, should they deny claims that have pre-authorization.
Verify Client Benefits
Before scheduling any client to receive therapy, verify their benefits. This process can be tedious and unnecessary, especially for returning clients. However, insurance policies can change quickly, and clients rarely know the minutiae of their medical plan.
Verification of benefits is the process of confirming the client’s insurance plan covers a service. Insurers’ online portals are the easiest way to verify this information. Call the payer for more details for those who lack online portals or have limited information. Staff should also note the degree of coverage, any max limits, and whether pre-authorization is required.
Check CPT Codes
Current Procedural Terminology (CPT) codes are part of a HIPAA-regulated information system that matches services with specific codes. Medical professionals use codes to describe a procedure and detailed additional information through Modifiers. Misreading or mismatch of codes is a common reason for denials and inadequate reimbursements.
Medical coders often use Provider notes to understand the details of the service done in that session. Ensure that your Providers write in detail that can clearly distinguish similar procedures. The CPT Editorial Panel constantly updates codes, so always refer back to an official source to check the latest codes for that service.
Know E/M Codes Vs. Psychiatric Evaluation Codes
Behavioral healthcare practitioners commonly employ two types of codes. Coders use evaluation and management (E/M) codes when a physician evaluates a new medical problem. There are three documentation types E/M code users must provide.
● History: Includes the history of the illness, social and family history, and a review of systems.
● Examination: Includes the type of examination performed, the nature of the problem, and the client’s history.
● Medical Decision Making: Includes the number of diagnoses or treatment options documented during the session, the complexity of the reviewed data, and the risk of complications.
By contrast, psychiatric evaluation codes are for diagnostic assessment. This assessment can include items that would typically fall under evaluation and management. However, coders must avoid using E/M codes for the diagnostic process.
Follow Insurance Guidelines
Different payers hold unique standards for how they want their claims submitted. An insurer may deny claims even with correct CPT codes if other information is required or need to be corrected. Additionally, insurers may create narrow timely filing limits by when practices can request reimbursements. Check this timely filing limit (TFL) for each payer since they vary by payer.
Review Claim Denials
Many claim denials are appealable. Document the types of denials you receive to find any patterns. Typically, insurers will delineate the error type in their report. Remember, insurers may have a limited, timely filing limit (TFL) for re-submissions or appeals.

FAQs


ABA providers are grappling with high staff turnover (up to 65%), rising burnout, administrative overload, and stagnant reimbursement rates. These challenges directly impact care continuity, clinical outcomes, and operational performance.


Operational inefficiency costs ABA teams up to 10 hours per staff member per week, contributing to burnout, denied claims, and longer accounts receivable (A/R) cycles. These inefficiencies ultimately result in reduced revenue and patient dissatisfaction.


Burnout leads to costly turnover, lower client retention, and decreased productivity. Recruiting and replacing a BCBA or RBT can cost up to $5,000 per hire, plus months of lost revenue and disruption to morale.


High-performing ABA organizations invest in clear career pathways for BCBAs and RBTs, align compensation with market benchmarks, and foster peer-led mentorship, flexible schedules, and wellness programs.


Automation tools like Plutus Health's Zeus streamline eligibility verification, denial management, and billing, reducing manual workloads by 5–10 hours weekly per clinician and improving clean claim rates by 95%.


Outsourcing revenue cycle management can improve collections, reduce denials by up to 30%, and free clinicians from billing-related admin tasks, resulting in better client care and financial outcomes.


One $200 million ABA network partnered with Plutus Health to automate eligibility and accounts receivable (A/R) processes. The result: $2M reduction in legacy A/R and a 97% Net Collection Rate.


By improving operational efficiency, investing in technology, and ensuring workforce stability, ABA leaders can align outcomes with reimbursement. Plutus Health supports this transition with scalable RCM and automation strategies.

To bill Medicaid for ABA services, providers must ensure credentialing is complete, services are pre-authorized, and claims use the correct codes and modifiers. Medicaid requirements vary by state, so always follow state-specific billing rules.


Common ABA billing mistakes include:
- Incorrect or missing CPT codesplan
- Lack of documentation or treatment
- Uncredentialed providers rendering services
- Submitting duplicate or late claims


Without proper credentialing, providers can’t get reimbursed. Insurance and Medicaid require that BCBAs, RBTs, and organizations are credentialed and contracted. Delays in credentialing often cause revenue losses and claim rejections.
