Insurance billing can often feel like a daunting task for therapists in private practice in the US. Between navigating the complexities of credentialing, verifying coverage, submitting claims, and managing denials, it’s easy to see why so many practitioners are overwhelmed. However, mastering insurance billing is essential for growing a successful practice. 

In fact, 90% of physicians agree that adopting efficient billing processes significantly improves cash flow and reduces administrative burdens. In this blog, we will walk you through the critical aspects of insurance billing, offering valuable insights into everything from in-network vs. out-of-network billing to handling common billing codes.

By following these steps, therapists can streamline operations, reduce billing errors, and ensure they are getting paid for their services—all while providing better care for their patients. But before we dive in, let's try to learn more about insurance billing. 

Understanding Insurance Billing for Therapists

Accepting insurance can be a game-changer for many therapy practices, but it comes with its own set of challenges. Whether you’re just starting out or looking to optimize your current billing processes, understanding the benefits and drawbacks of accepting insurance is crucial.

  • Benefits and Drawbacks of Accepting Insurance

Here are some of the benefits and drawbacks:

Benefits vs. Drawbacks of Accepting Insurance
Benefits vs. Drawbacks of Accepting Insurance
Benefits of Accepting Insurance Drawbacks of Accepting Insurance
Expanded Reach: Accepting insurance makes your practice accessible to more patients, including those who cannot pay out-of-pocket. Delayed Payments: Therapists may face delays in receiving payments from insurance providers.
Consistent Revenue Stream: A larger patient base can lead to a steadier revenue stream through insurance payments. Lower Reimbursement Rates: Insurance often offers lower rates compared to direct-pay clients.
Increased Visibility: Being listed in insurance directories boosts your practice’s visibility, attracting more patient referrals. Administrative Burden: Filing claims and managing rejections takes significant time and effort away from patient care.
Risk of Coding Errors: Mistakes in coding or documentation can lead to rejections, adding more time to administrative tasks.

  • Deciding Between In-Network and Out-of-Network Billing

When considering insurance billing, one of the first decisions therapists must make is whether to join insurance networks or operate independently as an out-of-network provider. Each approach comes with its own benefits and trade-offs.

In-Network Providers:

In-network providers sign formal agreements with insurance companies and accept their set rates for services. While this typically means lower reimbursement rates, it often results in a higher volume of patients due to lower out-of-pocket costs for clients. Being an in-network provider can increase your practice’s exposure, as patients tend to prefer providers who accept their insurance, especially when costs are a factor.

Out-of-Network Providers:

Out-of-network therapists, on the other hand, have the freedom to set their own rates, which may result in higher earnings per session. However, patients may have to pay more out of pocket, which can limit the number of clients willing to seek your services. This model often works well for specialized practices where patients are willing to pay a premium for niche or highly sought-after services. Carefully evaluating your patient demographics and practice goals can help determine which option aligns with your clinic’s needs.

  • Key Insurance Terminology: Insurance Provider, Billing Claim, Credentialing

Understanding key insurance terms is equally critical to managing the billing process smoothly. These terms will often come up when dealing with insurance companies and while submitting claims.

  • Insurance Provider: An insurance provider is the company or organization that offers health coverage to individuals or groups. It’s important to be familiar with the major insurance providers in your region and to know which ones are most commonly used by your clients. Understanding your clients’ insurance plans will help you provide better service and avoid billing issues later on.
  • Billing Claim: A billing claim is a formal request for payment that you submit to the insurance provider after services have been rendered. The claim must include detailed information about the services provided, including accurate coding (such as CPT codes) and patient information. Mistakes in these claims can lead to payment delays or rejections, so it’s crucial to submit them correctly the first time.
  • Credentialing: Credentialing is the process of verifying your qualifications with insurance companies so you can become an authorized provider. Without proper credentialing, you cannot bill insurance companies or get reimbursed for your services. Credentialing is often a lengthy process that requires careful attention to detail, but it is a vital step for therapists who want to broaden their client base.

Now that you’re familiar with these key terminology, it’s time to dive deeper into credentialing, a crucial process for therapists who wish to accept insurance.

Getting Credentialed

As we already discussed, Credentialing is essential for any therapist looking to expand their practice through insurance acceptance. This process allows you to bill insurance companies directly and ensures that your qualifications are recognized by insurance providers.

1. Importance of Credentialing for Therapists

Credentialing ensures that you meet the professional standards set by insurance companies. Without it, you won’t be able to accept insurance from patients, limiting your client pool to those willing or able to pay out-of-pocket. This could severely reduce the number of clients you’re able to serve, especially in areas where insurance-based care is the norm. Proper credentialing not only allows you to expand your practice but also builds trust with both insurers and clients.

2. Steps for Credentialing: Required Documents and Application Process

The credentialing process involves submitting various documents that prove your qualifications, including your license, education credentials, and malpractice insurance. Each insurance provider may have its own application process, but in general, you’ll need to:

  • Gather your professional documents, such as licenses and certifications.
  • Complete the application forms provided by the insurance companies.
  • Submit these forms along with your documentation.
  • Wait for verification and approval, which can take several weeks or months.

Once credentialed, you will be listed as an in-network provider, and clients with that insurance plan will be able to use their coverage at your clinic.

3. Considerations in Selecting Insurance Providers

When selecting which insurance providers to work with, it’s important to consider the reimbursement rates they offer and their ease of working with healthcare providers. Some companies offer higher reimbursement but may have stricter billing guidelines. Additionally, choosing providers that are popular in your area can help you attract more clients. Research each provider’s claim approval process, as well as any potential delays in payments, before deciding which credential to credential.

With credentialing in place, the next critical step is verifying your clients’ coverage and understanding the role of pre-authorization in certain cases.

Verification and Authorization

Before providing therapy services, it’s essential to verify a client’s insurance coverage and, in some cases, obtain pre-authorization to ensure the services will be covered.

Importance of Coverage Verification

Insurance verification is the process of confirming that a client’s insurance plan will cover the services you plan to provide. This prevents surprises for both you and the patient when it comes time to submit a claim. 

With SPRY PT’s integrated system, real-time eligibility checks make this process seamless, reducing the risk of errors and ensuring that the client’s insurance is active and applicable.

Role of Pre-Authorization in Client Services

Pre-authorization is sometimes required before certain therapies can be performed. This step involves submitting a request to the insurance company to determine whether the treatment is medically necessary and covered under the client’s plan. Failure to obtain pre-authorization could result in the insurance company denying payment for the service, leaving the client responsible for the full cost. Being proactive with pre-authorization ensures smooth payment later on.

Once coverage is verified and any necessary authorizations are in place, you’re ready to submit claims for the services you’ve provided. Let’s explore how to do this effectively.

Submitting Insurance Claims

Submitting insurance claims accurately and completely is essential for timely reimbursement in any therapy practice. In this, we will cover the crucial components needed for successful claim submission, helping therapists avoid common errors and manage rejections efficiently. Here’s what we’ll go over:

  • The Client’s Personal Details – Essential information needed for accurate identification and claim linking.
  • The Therapist’s Details – Key details to verify the service provider's credentials and authorization.
  • Accurate CPT Codes to Describe the Services Rendered – Selecting the appropriate codes for services provided.
  • Dates of Service and Detailed Descriptions – Ensuring session timing and details align with documentation.
  • Handling Rejections and Denials: Reasons and Appeals Process – Steps to resolve claim rejections and manage appeals effectively.

Steps for Successful Claim Submission: Required Information

Submitting an insurance claim is a crucial part of the billing process in any therapy practice. Accurate and timely claim submission ensures that you receive reimbursement for the services provided to your clients. However, to ensure the claim is processed without delays or denials, it's essential to gather and include the correct information.

Here are the key components required for successful claim submission:

The Client’s Personal Details

The foundation of any claim submission begins with the client’s personal information. Missing or incorrect client details are common reasons for claim rejections, so it’s crucial to double-check this information before submission. The key pieces of information required include:

  • Full Name: Ensure that the client’s name matches exactly as it appears on their insurance card. Even minor discrepancies, such as a middle initial or name suffix, can cause delays in processing.
  • Date of Birth: Insurance providers use the date of birth to verify the client’s identity and eligibility.
  • Insurance ID Number: This is the unique number assigned by the insurance provider to the client. It is critical for linking the claim to the correct insurance account.
  • Group Number: Some insurance plans, particularly those provided through employers, may require a group number in addition to the insurance ID. This number helps identify the employer or plan sponsor.
  • Address and Contact Information: Although not always mandatory for claim submission, it’s important to maintain up-to-date contact details in your records to resolve any issues that might arise with the claim.

By ensuring that all of this information is accurate and up to date, you can avoid common errors that lead to rejected claims.

The Therapist’s Details

Next, you’ll need to include the therapist’s information to identify who rendered the services. Insurance providers use this information to verify that the therapist is credentialed and authorized to provide the billed services. The essential therapist details include:

  • Full Name and Credentials: The therapist’s name and professional designations (e.g., LCSW, LPC, LMFT) must be included to confirm their qualifications.
  • License Number: This is a critical piece of information that allows insurance companies to verify that the therapist is properly licensed to practice. It is typically provided by the state licensing board.
  • National Provider Identifier (NPI): The NPI is a 10-digit, unique identification number assigned to healthcare providers in the U.S. It is used universally to identify the therapist when submitting claims to insurance providers. If you work in a group practice, the practice may also have its own NPI.
  • Provider Information: Include the clinic’s name and contact details, such as address, phone number, and fax number, to provide a complete profile of the billing entity. This helps insurers direct any inquiries or communications about the claim to the right place.

Ensuring that this information is correct and up-to-date helps reduce the chances of processing delays or denials related to provider verification.

Accurate CPT Codes to Describe the Services Rendered

CPT (Current Procedural Terminology) codes are perhaps the most important part of the claim submission, as they directly represent the services provided during the therapy session. Each service, whether it’s a 45-minute individual therapy session, a diagnostic evaluation, or a family counseling session, has a specific CPT code that insurance companies use to determine coverage and reimbursement rates.

To submit an accurate claim, you need to:

  • Select the correct CPT codes for the service provided. For example:some text
    • 90834 for a 45-minute individual therapy session.
    • 90837 for a 60-minute individual therapy session.
    • 90791 for a psychiatric diagnostic evaluation.
  • Ensure that the code reflects the correct session length and type of service. For instance, using a 45-minute code for a 60-minute session will likely lead to claim rejections or reduced reimbursement.

CPT coding accuracy is essential, as even a small mistake in coding can result in payment delays or claim denials. Integrated clinic management software like SPRY PT can assist by automatically suggesting the appropriate CPT codes based on the services documented, reducing the risk of human error.

Dates of Service and Detailed Descriptions

Each claim must include the dates of service for the therapy session or sessions being billed. This information helps insurance companies verify when the services were rendered and ensure that they fall within the coverage period for the client’s insurance plan. The key details include:

  • Date(s) of Service: Clearly indicate the exact date or range of dates on which the services were provided.
  • Duration of the Session: Ensure that the session length is accurately recorded to match the selected CPT code. For example, if a 60-minute session was conducted, the claim should reflect this with the corresponding CPT code (e.g., 90837).

Submit accurate claims without working overtime or hiring billers using SPRYPT’s automated billing system.

In addition to the dates, providing a detailed description of the services rendered helps clarify the nature of the therapy provided and supports the claim. This can be a brief description that aligns with the CPT code. For instance:

  • "Individual psychotherapy session, 60 minutes" for CPT code 90837.
  • "Psychiatric diagnostic evaluation" for CPT code 90791.

Electronic claims submissions, particularly through systems like SPRY PT, help automate much of this process, reducing errors and speeding up the time to payment. Book a demo with SPRY PT to see how automated claims can streamline your practice and enhance revenue flow.

Handling Rejections and Denials: Reasons and Appeals Process

Despite submitting a thorough claim, rejections can still occur due to coding errors, missing information, or services not covered under the patient’s plan. Handling claim denials efficiently is crucial to maintaining cash flow. When a claim is rejected, the appeal process allows you to resubmit the claim with corrected information. SPRY PT’s billing software tracks denials and assists in quickly resolving these issues, increasing your approval rates and reducing revenue loss.


Once the claims are submitted, it’s time to manage client payments for co-pays, deductibles, and coinsurance. Transparency in this area is key to maintaining a positive client experience.

Navigating Client Payments

Even with insurance coverage, clients are often responsible for co-pays, deductibles, and coinsurance. Being transparent about these payments helps build trust with clients and ensures smooth billing interactions.

Different Types of Client Payments: Co-pays, Deductibles, Coinsurance

  • Co-pays: A fixed amount clients must pay for each session, typically determined by their insurance plan.
  • Deductibles: The amount clients must pay before their insurance begins to cover services.
  • Coinsurance: A percentage of the cost of services that clients must pay after meeting their deductible.

Being clear about these payments ensures that clients understand their financial responsibilities up front, avoiding confusion later on.

Transparency and Communication with Clients Regarding Payments

Communicating clearly about insurance coverage and client payment obligations builds trust and reduces the risk of misunderstandings. Having conversations early on about what insurance will cover and what the client is responsible for can prevent payment disputes. Offering flexible payment options or setting up automatic billing can also enhance the client experience and improve your clinic’s cash flow.

Understanding how payments work is crucial, as is having a good grasp of the billing codes used in therapy. Let’s now dive into the most common CPT codes used in therapy billing.

Common Billing Codes in Therapy

For therapists, understanding and using the correct billing codes—specifically CPT codes—is essential for both accurate documentation and ensuring timely payment from insurance providers. These codes form the backbone of the claims process, allowing therapists to communicate effectively with insurance companies about the services rendered. Misusing these codes can result in claim rejections, delayed payments, or even underpayment, which can significantly disrupt a practice’s cash flow.

Explanation and Usage of CPT Codes

Here’s a more concise version:

CPT codes, or Current Procedural Terminology codes, standardize how healthcare providers describe services. In therapy, these codes categorize specific sessions, evaluations, and treatments, helping insurers understand the type and duration of services provided. Accurate coding ensures fair compensation and supports compliance.

Each CPT code corresponds to a procedure and time spent with the patient. For example, there are different codes for a 45-minute therapy session (e.g., 90834) versus a 60-minute one (e.g., 90837). Proper coding not only secures timely reimbursement but also protects therapists during audits, as insurance providers regularly verify claims for accuracy. Using the correct codes is essential for smooth, compliant practice operations.

Examples of Common Codes 90834, 90837, 90791

Several CPT codes are widely used in therapy, and each is linked to a specific type of session or evaluation. Here are some of the most frequently used CPT codes in the field:

  • 90834: This code is used for individual psychotherapy sessions lasting approximately 45 minutes. It’s one of the most common codes used by therapists, as many sessions fall within this time frame.
  • 90837: This code covers individual psychotherapy sessions lasting 60 minutes. Therapists may opt for this code when they need more time to conduct an in-depth session with a client. The key distinction between 90834 and 90837 is the duration, but both are commonly billed depending on the therapist's schedule and client needs.
  • 90791: This code is used for psychiatric diagnostic evaluations. It’s often billed when therapists conduct an initial evaluation to assess the patient’s mental health status, create a treatment plan, or diagnose a specific disorder. Unlike the therapy session codes, this code is tied to the evaluation phase and doesn’t include psychotherapy itself.

Other codes exist for group therapy, family therapy, and more specialized treatments, but 90834, 90837, and 90791 are the backbone of most therapy billing. Correct usage of these codes is crucial to ensure that the services provided are accurately represented and reimbursed.

Importance of Accuracy in CPT Coding

Accurate coding does more than secure payments—it ensures a streamlined billing process that benefits both your practice and your clients. Here’s why accuracy matters:

  • Reduces Payment Delays: Correct CPT codes minimize claim rejections and ensure faster reimbursement.
  • Ensures Fair Compensation: Accurate coding matches services to reimbursement; for instance, using the right code for a 60-minute session (e.g., 90837) prevents underpayment.
  • Improves Client Satisfaction: Avoids unexpected billing issues and insurance disputes, creating a smoother experience for clients and therapists alike.

Best Practices for CPT Coding

To make sure you’re using CPT codes effectively, consider the following best practices:

  1. Stay Updated: CPT codes are regularly updated, so it’s important to stay informed about any changes. A code that was accurate last year may no longer be valid, and using outdated codes can result in claim rejections.
  2. Use Integrated Software: Clinic management software like SPRY PT can help ensure you’re using the correct CPT codes by automating much of the billing process. The software is regularly updated with the latest codes, which helps you avoid coding errors.
  3. Double-Check Your Work: Even with software, it’s a good idea to review your claims before submission. Make sure that the codes used match the services provided, especially if you’ve adjusted session lengths or provided additional services during the appointment.
  4. Educate Your Team: If you have administrative staff handling billing, make sure they are trained in proper CPT coding practices. Errors can often arise if your team isn’t fully versed in the latest coding requirements.

So, now that we are aware of the common billing codes in therapy, let’s also briefly learn about implementing effective billing practices that can streamline your clinic’s processes.

Implementing Effective Billing Practices
