Accurate medical billing is a cornerstone of sustainable practices for mental health counselors, yet it’s often fraught with complexity. The landscape of medical billing codes, with its evolving terminology and acronyms, can be daunting, even for seasoned professionals. A single miscoded service or a piece of missing information can trigger significant delays in revenue, increase the likelihood of claim rejections, and disrupt the financial health of your practice.
Mental health professionals and their administrative teams must skillfully navigate a complex coding environment, juggling CPT, ICD-10, and DSM-5 codes. The risk of selecting an incorrect code is ever-present, particularly within the nuanced realm of mental and behavioral health. This article aims to clarify some of the most frequently used diagnosis codes in mental health counseling, empowering you to utilize them with greater confidence and accuracy.
Understanding CPT Codes in Mental Health Billing
Current Procedural Terminology (CPT) codes are a standardized and regularly updated coding system managed by the American Medical Association. These codes are fundamental to medical billing across specialties, including mental healthcare. While CPT codes are prevalent, it’s crucial to remember they are not the only codes relevant to mental health professionals.
In 2013, CPT codes specific to psychiatry, psychology, and behavioral health services underwent a substantial revision, with no further major updates anticipated in the near future. CPT codes primarily describe the services, procedures, and treatments provided to clients. These five-digit codes are broadly applied throughout the medical field, often supplemented by add-on codes for more granular service descriptions.
For efficient medical billing, CPT codes are indispensable for ensuring precise claims and timely reimbursement from insurance providers and other payers. Incorrect CPT coding can severely impede your revenue cycle management, leading to claim rejections, denials, and payment delays, especially when undercoding or upcoding occurs.
Undercoding and Upcoding: What You Need to Know
Undercoding
Undercoding involves using a CPT code that corresponds to a less expensive treatment or a less severe diagnosis than what was actually provided. While sometimes unintentional, undercoding is often done deliberately to reduce patient costs or avoid scrutiny from payers. However, even unintentional undercoding is considered non-compliant and can lead to penalties.
Upcoding
Upcoding is the opposite, where a CPT code for a more expensive treatment or a more significant diagnosis is used. Frequently, upcoding is a deliberate attempt to secure higher reimbursement. While unethical and potentially illegal, unintentional upcoding can also occur due to staff error or inadequate training. Regardless of intent, the responsibility for coding accuracy rests with the healthcare provider, and audits can result in significant repercussions.
Common CPT Codes in Mental Health Counseling
Fortunately, within the vast CPT codebook of over 800 codes, only a small subset is commonly used by mental health professionals. These frequently utilized codes include:
- 90791 – Psychiatric Diagnostic Evaluation: Used for the initial comprehensive assessment to diagnose a patient’s psychiatric condition.
- 90792 – Psychiatric Diagnostic Evaluation with medical services: Similar to 90791 but includes medical services as part of the diagnostic evaluation.
- 90832 – Psychotherapy, 30 minutes (16-37 minutes): For individual psychotherapy sessions lasting approximately 30 minutes.
- 90834 – Psychotherapy, 45 minutes (38-52 minutes): For individual psychotherapy sessions lasting approximately 45 minutes.
- 90837 – Psychotherapy, 60 minutes (53 minutes and over): For individual psychotherapy sessions lasting approximately 60 minutes or longer.
- 90846 – Family or couples psychotherapy, without the patient present: For family or couples therapy sessions where the identified patient is not present.
- 90847 – Family or couples psychotherapy, with the patient present: For family or couples therapy sessions where the identified patient is present.
- 90853 – Group Psychotherapy (not family): For psychotherapy conducted in a group setting (excluding family therapy).
- 90839 – Psychotherapy for crisis, 60 minutes (30-74 minutes): For crisis intervention psychotherapy sessions, typically lasting around 60 minutes.
The Interplay of CPT, ICD-10, and DSM Codes
While the number of frequently used CPT codes in mental health is relatively small, their connection to ICD-10 and DSM codes is critical. Mental health professionals and their administrative teams must be proficient in all three coding systems and stay informed about updates and revisions.
Understanding ICD-10 and DSM-5 in Relation to CPT Codes
To grasp the relationship between ICD-10, DSM-5, and CPT codes, it’s essential to first understand the connection between ICD-10 and DSM-5. Both ICD-10 and DSM-5 codes are used for diagnosis, but with distinct roles.
ICD codes are part of the World Health Organization’s (WHO) International Classification of Diseases & Related Health Problems. In the context of billing, ICD codes are used in conjunction with CPT codes when submitting claims to private insurance companies and public payers.
DSM-5 codes are derived from the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, published by the American Psychiatric Association. The DSM-5 serves as a diagnostic and taxonomic manual specifically for mental disorders.
Crucially, ICD-10 and DSM-5 codes are not separate systems for mental health diagnosis coding; rather, the DSM-5 is designed to guide practitioners in selecting the correct ICD-10 code for a specific mental health condition. The DSM-5, published in May 2013 and implemented in January 2014, preceded the broader healthcare transition from ICD-9 to ICD-10, which took effect in October 2015.
The DSM-5 is particularly relevant to mental health as it specifically lists and endorses most mental and behavioral health ICD-10 codes. Confusion sometimes arises, leading some professionals to believe in a separate set of “DSM codes” distinct from ICD codes. However, in reality, the DSM-5 is the accepted guide for using ICD-10 codes in mental health.
Ultimately, the connection between an ICD-10 code and a CPT code is that the diagnosis (ICD-10) must justify the medical necessity of the treatment or service provided (CPT code).
Adding another layer, HIPAA regulations since 2003 mandate the inclusion of an ICD code for any electronic healthcare transaction related to billing, reimbursement, or reporting. This means that to successfully bill insurance or payers, documentation must include both a CPT code detailing the service provided and an ICD-10 code clearly outlining the patient’s diagnosis that necessitates the service.
