Billing Insurance as a Therapist: A Beginner’s Guide to Codes, Claims, and Getting Paid

For many therapists in private practice, the decision to accept insurance is a major step. While it can make your services more accessible, it also introduces the complex world of billing, codes, and claims. The process can feel intimidating, but with the right knowledge and tools, you can navigate it with confidence. This guide will break down the essentials of billing insurance, from understanding codes to filing claims correctly.

At ClinikEHR, we believe that billing shouldn't be a barrier to running a successful practice. Our platform is designed to automate and simplify the insurance process, so you can get paid without the headache.

Why Insurance Billing Feels So Overwhelming

Insurance billing has its own language, filled with acronyms, codes, and specific rules that vary by payer. For a therapist focused on clinical care, learning this new system can feel like a daunting and unwelcome distraction. The fear of making a mistake that leads to a denied claim is real, and it’s why many therapists initially avoid accepting insurance altogether. But by breaking it down into manageable steps, the process becomes much clearer. A great resource for understanding the payer side of things is the National Association of Insurance Commissioners (NAIC).

Understanding CPT Codes and Modifiers

CPT (Current Procedural Terminology) codes are the foundation of insurance billing. These five-digit codes tell insurance companies what service you provided. For therapists, a few codes make up the bulk of billing:

• 90791: Psychiatric Diagnostic Evaluation (used for intake/initial assessment).
• 90834: Psychotherapy, 45 minutes.
• 90837: Psychotherapy, 60 minutes.
• 90847: Family or couples psychotherapy, with the patient present.

In some cases, you may also need to use modifiers, which provide additional information about the service. For example, a modifier might be used to indicate that a service was provided via telehealth. For an official and detailed list of codes, you can always refer to the American Medical Association (AMA), which maintains the CPT code set.

How to File Claims Correctly

A claim is the formal request for payment that you send to an insurance company. There are a few key components to a clean claim (one that is processed without errors):

1. Patient Information: Must be accurate, including name, date of birth, and insurance ID number.
2. Provider Information: Your NPI (National Provider Identifier) and practice details.
3. Diagnosis Code (ICD-10): This code identifies the client's diagnosis.
4. CPT Code and Date of Service: The service you provided and when you provided it.

Most therapists file claims electronically through a clearinghouse. A clearinghouse acts as a middleman, formatting your claims to meet the specific requirements of each insurance payer and transmitting them securely. This significantly reduces the chance of errors.

Avoiding Common Billing Mistakes

Denied claims can disrupt your cash flow and create administrative headaches. Many denials are caused by simple, avoidable errors:

• Incorrect or Missing Information: A typo in a name or an incorrect policy number is one of the most common reasons for denial.
• Wrong CPT or ICD-10 Code: Using a code that doesn’t match the service or diagnosis will lead to a rejection.
• Lack of Medical Necessity: Your documentation must support the services you are billing for. Insurance companies can request to see your notes to verify that the treatment was medically necessary.
