In the evolving landscape of healthcare reimbursement, mental health providers face a unique set of challenges that differ significantly from those of general medical practices. From CPT coding to payer policies, and documentation standards to patient confidentiality laws, behavioral health billing requires specialized knowledge and systems. This makes choosing the right type of billing partner critical for long-term success.
So what exactly sets mental health billing companies apart from general medical billers? Let’s dive into the key differences and why mental health practices should consider a specialized billing partner. Looking for the best mental health billing company? This guide breaks down what to look for in 2025 and how to choose the right fit for your behavioral health practice.
1. Different CPT Code Structures and Requirements
Mental health billing relies heavily on time-based CPT codes, while general medical billing typically involves evaluation and management (E/M) codes, procedure codes, or surgical billing. Some of the most commonly used mental health CPT codes include:
- 90832, 90834, 90837: Psychotherapy sessions (30, 45, 60 minutes)
- 90791, 90792: Psychiatric diagnostic evaluations
- 90846, 90847: Family therapy
- 90863: Pharmacologic management with psychotherapy
- 96130–96138: Psychological and neuropsychological testing
- H0015, H0031, H2019: Medicaid-specific services like IOP, assessments, and behavioral interventions
These codes often have stringent documentation and time validation requirements. A general medical biller unfamiliar with behavioral health codes may submit incomplete or incorrect claims, leading to unnecessary denials or underpayments.
Choosing a specialized mental health billing company can help reduce denials and boost cash flow.
2. Payer-Specific Authorization and Coverage Rules
Mental health services frequently require prior authorization, session limits, or proof of medical necessity—especially for extended sessions (e.g., 90837) or intensive services (e.g., IOP).
Mental health billing companies are familiar with:
- Pre-authorization requirements for various payers
- State Medicaid regulations for behavioral services
- Telehealth policies (e.g., modifier 95 vs. GT)
- Utilization review requirements for ongoing therapy
By contrast, general billers may overlook these requirements, resulting in denied claims or delayed payments. Specialized billers often have payer-specific templates and workflows that streamline approval and documentation.
3. Understanding of Confidentiality and Documentation Standards
Mental health documentation must balance clinical detail with confidentiality. Notes must include therapeutic goals, medical necessity, and progress, but they must also comply with HIPAA and 42 CFR Part 2 regulations regarding sensitive substance use data.
Behavioral health billers:
- Know how to handle sensitive records securely
- Are trained to identify compliance risks in progress notes
- Understand what payers look for during audits (especially for CPT 90837 and H-codes)
General medical billing teams may not be aware of these specialized documentation standards, potentially exposing providers to legal or compliance risks.
4. Telehealth Complexity for Mental Health Services
Mental health practices adopted telehealth more broadly and earlier than general medical practices. However, billing for telehealth in mental health varies significantly by payer and state.
Specialized mental health billing companies stay updated on:
- State-specific telehealth parity laws
- Temporary vs. permanent telehealth codes post-pandemic
- Audio-only billing policies (common in Medicaid)
General medical billers may treat telehealth services uniformly, leading to incorrect modifiers or missed reimbursements for virtual sessions. Before signing a billing contract, read these red flags in mental health billing that can lead to denied claims, revenue loss, or compliance risks.
5. Higher Denial and Audit Risk Without Specialization
Because of the nuanced requirements for time-based coding, authorization, and documentation, mental health services are more prone to denial. In 2025, CMS even expanded its audits across all Medicare Advantage plans, increasing pressure on providers to maintain detailed documentation.
Mental health billing companies are experienced in:
- Appealing denials for time and necessity-based codes
- Justifying frequency of care in documentation
- Managing A/R and resubmissions efficiently
A general medical biller may lack the expertise to address these specific denial reasons or proactively prevent them.
6. Client Communication and Clinical Alignment
Mental health providers often require tailored support, including:
- Progress note audits
- Weekly revenue tracking
- Payer-specific advice for clinical documentation
Specialized billers act as part of the clinical team, helping improve internal processes and patient record alignment. Generalist billing companies may offer cookie-cutter services that fail to meet the depth required for behavioral health success.

7. Credentialing and Contracting Expertise for Behavioral Health
Credentialing mental health providers often requires working with multiple taxonomy codes (e.g., psychotherapy and medication management), group NPIs, and an understanding of state Medicaid carve-outs. Specialized billing firms often handle:
- Medicaid and Medicare credentialing
- CAQH updates for behavioral providers
- Payer contracting support for therapy-specific services
A generalist billing service may not offer these capabilities or may treat credentialing as a one-size-fits-all process, which doesn’t work in behavioral healthcare.
Final Thoughts: Choose Expertise Over Convenience
While general medical billers may offer broad capabilities, they often fall short in the specific needs of mental health providers. Billing mistakes, documentation gaps, and misunderstanding of payer policies can lead to revenue loss, audits, or provider burnout.
Mental health billing companies, like Global Tech Billing LLC, bring:
