The 6 Challenges Unique to Behavioural Health Billing (And Solutions)

Behavioral health practices, treating conditions like depression, anxiety, addiction, and other mental health disorders, face billing complexities beyond typical medical specialties. Unlike standard medical services, behavioral health billing involves a wide range of procedure codes and diagnoses, unique insurance policies, and extra privacy rules. 

For example, one source notes that “behavioral health billing stands out from other medical specialties because of its complex procedural structure” and covers a broad array of conditions. This means therapists, psychiatrists, and clinics must navigate special rules as well as inconsistent coverage limits across payers. The net effect is that claims must be meticulously prepared or they risk denials, underpayment, or delays. 

Understanding these unique challenges and how to address them can help behavioral health providers improve cash flow and focus on patient care. Below, we detail six key billing challenges unique to behavioral health, with practical strategies to overcome each.

Common Challenges in Behavioral Health Billing and Solutions to Tackle Them

1. Documentation and Medical Necessity

Behavioral health billing demands exceptionally detailed documentation. Payers require clinicians to justify every session with clear clinical notes linking patient symptoms, diagnoses, and treatments. As one guide explains, “the successful submission of behavioral health billing depends on the detailed documentation that directly supports the necessity of each procedure”. 

In practice, this means simply writing “supportive therapy” or “patient doing better” is often not enough. Insurers increasingly expect evidence-based descriptions to prove that therapy or medication management was medically necessary. Without this rigor, “generic documentation often fails to meet medical necessity standards, resulting in denied claims or payment delays”. 

Inconsistent note-taking across multiple clinicians also causes problems; one report notes that practices with several therapists often struggle to standardize notes, making coding and billing more error-prone.

Solutions: Improve Documentation Practices

• Standardize Clinical Notes. Create shared templates for intake assessments, treatment plans, and progress notes. These templates should prompt clinicians to include required details. Include diagnosis, duration, therapeutic interventions, and patient response. Electronic health records (EHRs) tailored to behavioral health can enforce completeness.
• Train Staff on Medical Necessity. Provide regular training so clinicians and billers understand what documentation payers expect. Show them how to tie each therapy session to a DSM-5 diagnosis. Emphasize that notes must justify why each service is needed.
• Conduct Audits Before Submission. Perform internal audits of charts and claims to catch missing information early. Review a sample of charts. This can reveal common documentation gaps. The team can correct them before filing claims.
• Use Detailed Codes Thoughtfully. When coding, make sure procedures and time-based services match the documentation exactly. Use 90834 for 45-minute therapy. Use 90791 for a diagnostic evaluation. Accurate coding goes hand-in-hand with strong documentation.

A solid documentation process is critical. Even skilled clinicians find it challenging to capture all the needed details for billing. Clear note templates and training can prevent denials caused by vague or incomplete records.

2. Technology and Administrative Burdens

Implementing and maintaining billing systems and EHRs can itself be a major challenge. While digital tools promise efficiency, setting them up is time-consuming and costly. As one source notes, adopting EHRs “poses administrative burdens” because practices must spend funds and staff-hours on training and customizing systems for behavioral health use. 

During implementation, workflows change, and data must be migrated; any technical glitches or downtime can disrupt billing and patient care. Smaller clinics, especially, may struggle when their staff wear multiple hats, juggling clinical duties with learning new software.

Solutions: Reduce Technical Friction

• Plan Thorough Implementation. Roll out new billing software or EHR modules in phases. Work closely with the vendor to ensure the system meets behavioral health needs. Allocate protected time for staff training.
• Leverage Specialists and Support. Consider hiring a consultant or adding a certified EHR trainer during onboarding. For example, contracting with an experienced revenue cycle management (RCM) service or a certified coder familiar with behavioral health can smooth the transition.
• Automate Routine Tasks. Use software features to automate eligibility checks, claim scrubbing, and reminders for missing information. Automating repetitive billing tasks reduces staff workload and errors.
• Outsource or Delegate Non-Clinical Tasks. Free clinicians’ time by having dedicated administrative staff or an outsourced billing partner handle claims submission and follow-up. Practices often find that delegating billing or credentialing work improves efficiency.
  

Even helpful tech can be overwhelming if unplanned. Many behavioral health providers report spending excessive time adjusting to new EHR and billing software. 

Mitigate this by phasing in systems carefully, securing vendor support, and considering external billing specialists who know behavioral health workflows.

3. Complex Coding Structure

Behavioral health billing involves multiple coding systems and nuances that add complexity. Providers must assign not just a diagnosis code (ICD-10) but also the correct procedural codes for therapy or medication management, often with add-on modifiers. For instance, psychiatry uses time-based CPT codes (like 90834 for a 45‑minute session) as well as codes for evaluations (90791) and interactive complexity (90785), among others. 

Moreover, mental health diagnoses often rely on the DSM-5 terminology, which must then be mapped accurately to ICD-10 codes. In short, “the wide range of services covered by behavioral health billing necessitates multiple sets of codes and modifiers”. A single encounter may require an ICD-10 diagnosis code, one or more CPT therapy or psychiatric codes, and possibly HCPCS modifiers. 

This makes coding more challenging than many general medical services. One guide emphasizes that understanding psychiatry codes and modifiers typically requires a professional coder’s expertise.

Solutions: Master Specialized Coding

• Use Certified Behavioral Health Coders. Ensure that coding staff are trained specifically in mental health. Certified Professional Coders (CPCs) or certified coders with behavioral health experience will know the nuances (for example, the differences between 90847 family therapy vs. 90853 group therapy, or when to use the crisis intervention codes 90839/90840).
• Stay Current on Code Changes. The CPT and ICD code sets update regularly. Subscribe to coding newsletters, use coding software with updates, or provide periodic training so your team learns new mental health codes each year.
• Double-Check Time and Modifiers. Since many therapy services are time-based, train staff to record exact session lengths. Always review claims to ensure the modifiers (e.g., -52 for reduced services, or the appropriate place-of-service code for telehealth sessions) are applied correctly.
• Perform Coding Audits. Regularly audit a sample of claims to catch errors. For example, a billed psychotherapy code should match the documented time. Audits help catch systemic mistakes (like consistently undercoding or miscoding group vs. individual therapy) before they lead to significant revenue loss.

Proper coding ensures you get paid for all services delivered. Remember that behavioral health uses DSM-5 diagnoses plus ICD-10 and often bills in 30‑ or 45‑minute increments, unlike many medical offices. 

Having experienced coders and strong internal checks will reduce the high denial rates associated with coding mistakes.

4. Limited Coverage and Reimbursement Rates

Insurance coverage for mental health services is often more restrictive than for physical health. Payers routinely limit the number of therapy sessions per year or exclude certain services. 

• One analysis notes that health plans “vary widely in what they consider ‘medically necessary’ for mental health,” which creates confusion for providers. 
• On top of coverage limits, reimbursement rates for behavioral health services tend to be lower. 
• When payers set fee schedules, psychotherapy and psychiatric evaluation codes often pay less than analogous medical visits. 
• Providers sometimes find that accepting a particular plan means lower pay (and some even stop taking certain insurance for this reason). 
• These coverage gaps and low fees can threaten a practice’s financial viability, for example, one source warns that under-insuring mental health “leads to subpar treatment of patients, higher healthcare costs, and a low quality of life”.

Another hurdle is patient financial responsibility. As high-deductible health plans become more common, patients may initiate treatment without fully understanding their out-of-pocket costs. 

Behavioral health benefits can have separate deductible structures, which leads to patient balances that clinics must collect. According to one review, “the widespread adoption of high-deductible health plans creates significant collection challenges since mental health benefits may have different deductible structures than medical benefits”. Many clinicians spend time chasing unpaid patient balances on top of insurance billing, hurting cash flow.

Solutions: Clarify Benefits and Costs

• Verify Benefits Up Front. Check each patient’s coverage details before or at intake. Ask insurers to confirm which services are covered. Find out about visit limits and preauthorization rules. Document these in the patient’s file. Your team will know what insurance will pay.
• Educate Patients on Coverage. Communicate clearly about copays and potential charges. Explain the patient’s financial responsibility for sessions. Set up payment plans if needed. Transparent billing estimates help avoid surprises. Show a copay amount on the visit note as an example.
• Advocate for Parity (Where Possible). Be aware of laws like the Mental Health Parity and Addiction Equity Act. These laws require insurers to treat mental health benefits similarly to medical benefits. If you spot unfair limits, appeal denials. Cite parity rules in your appeals.
• Consider Diversifying Payers or Fee Structures. Some practices expand their payer mix to mitigate low reimbursements. Others offer a limited sliding-scale fee. You might accept more commercial plans. You could offer cash-pay packages for clients willing to forego insurance. The key is not being entirely dependent on one insurer’s low rates.

Insurance and reimbursement policies can change frequently. Keep an eye on payer updates. Watch for telehealth coverage changes. This prevents being blindsided by new restrictions.

Practices can reduce claim denials and unpaid bills by proactively clarifying benefits. Working within parity laws also helps reduce coverage issues.

5. Diverse Range of Services

Behavioral health encompasses a wider variety of billable services than many medical practices, each with its own codes and rules. Beyond standard individual therapy and psychiatry visits, practices often offer group therapy, family therapy, substance abuse counseling, psychological testing, and crisis services. 

According to one analysis, determining “which of the wide range of services presented should be financed” is a particular challenge. 

• For example, group therapy (CPT 90853) bills differently than individual sessions; medication management time is billed as an E/M code rather than psychotherapy codes. 
• If any billable service is missed or miscoded, revenue is lost. 
• A study of revenue leakage in behavioral health found many clinics undercode ancillary services (like group sessions, care coordination, or testing) simply out of confusion. 

Solutions: Capture Every Service

• Track All Service Types. Create a checklist of all services your practice provides. Ensure each type is entered and coded separately in the billing system. For instance, confirm that intake assessments, ongoing therapy, and medication follow-ups are not lumped into one code when they should be distinct.
• Educate Clinicians on Billing Implications. Train staff to recognize billable activities. For example, if a therapist spends extra time coordinating care or developing a treatment plan, note it in the record as a billable service. Know which cases allow add-on codes to capture legitimate extra work.
• Audit for Missed Charges. Periodically review past claims to find missed opportunities. Check if every therapy session, group meeting, or test administered in a given month was billed. In many clinics, simple omissions (like forgetting to bill for a family session or relapse prevention group) can add up to significant revenue if corrected.
• Use Practice Management Tools. Employ scheduling and billing software that ties appointment types to billing codes. For example, when you schedule a 45-minute therapy session, the system can automatically attach CPT 90834. This reduces human error in selecting codes for each encounter.

Every billable service in behavioral health, no matter how brief, matters. By putting processes in place to record and code each type of care, providers avoid underpayment and ensure the practice is reimbursed for the full spectrum of services offered.

6. Authorization and Precertification Requirements

Most mental health and substance use services require prior authorization from insurance companies, often at each stage of treatment. Unlike many routine medical visits, ongoing therapy sessions, psychological testing, or inpatient psychiatric care typically need insurer approval in advance. 

• One review explains that “behavioral health treatments frequently require prior authorization, not just initially, but throughout the course of treatment”. 
• Each payer has its own rules on how many sessions are covered and what documentation to submit. 
• The process is time-consuming and prone to error. 
• If a required authorization is missing or expires, the claim will be denied outright. 
• In fact, providers report that common denial reasons in behavioral health include “missing or expired authorizations” and “services exceeding frequency limitations”. 
• Re-submitting denied claims is costly and delays payment, as appeals often require even more paperwork.

Another related issue is provider credentialing and enrollment. Behavioral health practices often have multiple clinician types who each must be enrolled with payers. 

If a claim is submitted under a provider who is not yet credentialed or in-network, it will be rejected. Credentialing applications can take months; during that time, some practices may see clients out-of-network or defer care, hurting revenue.

Solutions: Proactive Authorization Management

• Verify and Obtain Authorizations Early. Integrate insurance verification into the intake process. Before the first session and periodically afterward, check whether pre-approvals are needed and submit requests immediately. Build an internal log to track authorization numbers and expiration dates.
• Use Authorization Tracking Tools. Many practice management or RCM platforms include authorization modules. Use software alerts to remind staff when an authorization is about to expire or when additional sessions need a new request. This prevents surprise lapses.
• Streamline Credentialing. Maintain a credentialing calendar. Submit applications to payers far in advance of enrollment deadlines. Assign one staff member to follow up on each application. Some clinics hire credentialing services to handle paperwork and expedite the process.
• Appeal Strategically. If a denial occurs due to authorization or credentialing, respond quickly with the required information. Keep detailed records so that you can appeal efficiently. Over time, track denial reasons to address the root cause.

Pre-certification headaches can be avoided with organization. By confirming coverage rules before treatment and monitoring all authorizations, practices prevent the costly denials that disrupt cash flow. 

Clear communication between administrative staff and clinicians is key: everyone should know the policy requirements so patients aren’t left in limbo when coverage is needed.
