Looking for CPT Codes: How to Find Common Codes for Mental Health Services

If you’re anything like me, you have a few CPT codes memorized or on a sticky pad somewhere. They’re a fact of life for any therapist, and using them accurately is crucial, as they ensure timely payment and compliance with regulations.

Navigating insurance billing and reimbursement can challenge any mental health provider, so it’s worth taking a closer look at regularly used CPT codes, and where to find more specialized ones. Let’s explore the CPT code lookup process, some common mental health service codes, as well as some guidance for how to use CPT codes correctly to help streamline billing.

Understanding CPT Codes

‍CPT codes are 5-digit numeric codes that describe medical, surgical, and diagnostic services offered by healthcare professionals. These codes fall into three main categories:

• Category I codes are the most common and cover routine procedures like psychotherapy and assessments. In billing, you’ll typically use these codes most often. Category I CPT codes identify specific, well-established procedures. 
• Category II codes track performance measures and quality of care. They rarely appear in mental health settings. 
• Category III codes apply to emerging technologies or services.

The American Medical Association (AMA) updates CPT codes annually to reflect changes in healthcare practices and technologies. Keeping up with these updates is important for accurate coding and billing.

How to Lookup CPT Codes

‍Several tools and resources help find CPT codes, making sure you stay accurate and follow the latest coding guidelines. Here are some of the most effective methods:

• Official Resources: The American Medical Association (AMA) website and the Centers for Medicare & Medicaid Services (CMS) offer reliable tools for checking CPT codes. Commercial coding software can also simplify the process.
• Online Databases: Searchable CPT code databases, like ICD-10 or dedicated CPT Code Lookup tools, provide easy-to-use interfaces for finding the right codes. These databases often include detailed descriptions and cross-references to other code sets.
• Manuals and Guides: CPT manuals and subscription services, such as those offered by AAPC or JustCoding, are valuable references for detailed information on coding guidelines and conventions.

When searching for CPT codes, use precise keywords related to the mental health service provided, such as "psychotherapy," "assessment," or "evaluation." This helps narrow down the results to the most relevant codes. If needed, apply modifiers to provide additional context about the service, such as the setting or duration.

To ensure accurate coding, choose tools that are regularly updated, easy to use, and provide detailed code descriptions. Keep clear documentation of all services rendered and the corresponding CPT codes used to support proper reimbursement claims and ensure transparency in case of audits.

Common CPT Codes for Mental Health Services

‍When providing mental health services, using the correct CPT codes ensures accurate billing and reimbursement. Here are some of the most frequently used CPT codes for various mental health services:

Psychotherapy Codes

• 90832: Psychotherapy, 16-37 minutes with patient and/or family member.
• 90834: Psychotherapy, 38-52 minutes with patient and/or family member.
• 90837: Psychotherapy, 53+ minutes with patient and/or family member.
• 90839: Psychotherapy for crisis, first 60 minutes.

Evaluation and Testing Codes

• 90791: Psychiatric diagnostic evaluation without medical services.
• 90792: Psychiatric diagnostic evaluation with medical services.

Group Therapy

• 90853: Group psychotherapy (other than a multiple-family group).

Family Therapy

• 90846: Family psychotherapy, 50 minutes; without the patient present.
• 90847: Family psychotherapy, 50 minutes; with the patient present.

Keep in mind that these codes might change, as the AMA updates CPT codes annually. Always check the most current CPT manual or online resources to ensure you’re using the correct codes for your services. Proper use of these codes helps simplify the billing process, ensures compliance with regulations, and facilitates timely reimbursement for the mental health services you provide.

Special Considerations for Mental Health Coding

‍When using CPT codes for mental health services, it's important to grasp the details that distinguish different types of services and how they should be coded. Here are some important considerations:

• Comprehensive vs. Focused Services: A comprehensive mental health evaluation (90791 or 90792) involves a more detailed assessment, typically occurring during an initial visit or when a significant change in treatment is needed. In contrast, a focused psychotherapy session (90832, 90834, or 90837) addresses specific issues and treatment goals. Accurately differentiating between these services ensures proper coding and reimbursement.
• Documentation: Thorough documentation supports the CPT code used and ensures appropriate reimbursement. Progress notes should clearly outline the services provided, the time spent, and the patient's response to treatment. Insufficient or vague documentation can lead to claim denials or audits.
• Insurance-specific Requirements: CPT coding practices and coverage can vary among private insurers, Medicare, and Medicaid. It's necessary to familiarize yourself with each payer's specific requirements, such as prior authorization, session limits, or excluded services. Not adhering to these requirements can result in denied claims or reduced reimbursement.

Code Bundling and Unbundling: Sometimes, CPT codes may need to be bundled or unbundled to accurately reflect the services provided. For example, when a psychotherapy session (90832, 90834, or 90837) occurs on the same day as a group therapy session with the same therapist (90853) the psychotherapy code should be reported separately from the group therapy code. Keeping up-to-date with the latest CPT coding guidelines and payer requirements is important for ensuring accurate reimbursement and maintaining compliance. Regularly reviewing coding resources, attending training sessions, and consulting with experienced billers or coding specialists can help you handle the complexities of mental health coding.

Common Coding Mistakes and How to Avoid Them

‍Accurate CPT coding ensures timely reimbursement and compliance with regulations. However, mental health providers may sometimes make mistakes that can lead to claim denials, delayed payments, or even legal consequences. Here are some common coding errors and how to avoid them:

• Misuse of Codes: Selecting the wrong CPT code based on session length or type of service happens often. Double-check the code descriptions to ensure they match the actual service provided. For example, using code 90837 for a 60-minute psychotherapy session when the session was only 30 minutes is incorrect.
• Omitting Modifiers: Modifiers provide important context about the service rendered, such as indicating a telehealth session. Failing to use appropriate modifiers can result in claim denials or incorrect payments. Familiarize yourself with the most common modifiers and when to apply them.
• Documentation Gaps: Insufficient or vague documentation can lead to audits or claim denials. Progress notes should clearly support the CPT code billed, including details about the service provided, confirmation that the client meets medical necessity for the service, duration, and patient's response. Regularly review your documentation practices to ensure they meet payer requirements.
• Overcoding/Undercoding: Billing for more or fewer services than actually provided can have serious consequences. Overcoding, or upcoding, involves billing a service at a higher level than rendered, which can be seen as fraudulent. Undercoding, or downcoding, means billing at a lower level, resulting in lost revenue. Accurately report the services provided to avoid these issues.

Other common mistakes include using outdated codes, unbundling comprehensive codes, failing to verify insurance coverage limits, and incorrectly reporting visit durations. To minimize errors, stay current with the latest CPT coding guidelines, attend training sessions, and consult with experienced billers or coding specialists when needed. Implementing a thorough review process before submitting claims can also help catch and correct mistakes early on.

How to Stay Up-to-Date with CPT Code Changes

‍Keeping up with CPT code updates is vital for accurate billing, reimbursement, and compliance with regulatory standards. As medical practices and technologies change, so do CPT codes. Here's how to stay informed about the latest changes:

• Annual Updates: The American Medical Association (AMA) releases CPT code updates annually, typically in the fall, with changes taking effect on January 1st of the following year. These updates include new codes, deleted codes, and revisions to existing codes. To track these changes, regularly check the AMA website, subscribe to their newsletter, or purchase the latest CPT code books.
• Continuing Education: Invest in ongoing training for yourself and your staff to ensure a thorough understanding of CPT code changes. Many organizations offer webinars, workshops, and online courses that cover the latest updates and their implications for your practice. Look for educational resources from reputable sources like the AMA, AAPC (American Academy of Professional Coders), or AHIMA (American Health Information Management Association).
• Online Tools and Apps: Use online resources and mobile apps that provide real-time updates on CPT code changes. These tools often include searchable databases, interactive tutorials, and helpful tips for implementing the latest codes. Many of these tools also offer customizable alerts and notifications to keep you informed of relevant changes.

To ensure a smooth transition when CPT codes are updated, review your practice's billing systems and forms to make sure they accommodate the latest codes. Work with your EHR vendor and clearinghouses to implement necessary changes and test the system to avoid potential claim denials or delays.
