Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental condition affecting millions worldwide. Within the spectrum of ADHD, the combined type is a common presentation. Navigating the complexities of medical diagnoses often involves understanding specific coding systems. In the United States, the International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) is the standard for diagnostic coding. This article delves into the specifics of the Adhd Combined Type Diagnosis Code, providing a comprehensive overview for anyone seeking clarity on this topic.
Decoding ICD-10-CM Code F90.2 for ADHD Combined Type
The ICD-10-CM code F90.2 is designated for Attention-deficit hyperactivity disorder, combined type. This code is crucial for medical billing, record-keeping, and statistical analysis within the healthcare system. Let’s break down what this means:
- F90.2 is a billable and specific code: This signifies that F90.2 is not a general or ambiguous code. It precisely identifies a diagnosable condition for which healthcare providers can seek reimbursement.
- Effective Date: The F90.2 code in the 2025 ICD-10-CM edition became effective on October 1, 2024. This highlights the importance of using the most current coding system for accurate medical documentation and billing. The code has remained consistent from 2016 to 2025, indicating its established place in the diagnostic framework.
- American ICD-10-CM Version: It’s essential to note that F90.2 is part of the American adaptation of ICD-10. International versions may have variations, emphasizing the need to use the correct coding system based on geographic location and healthcare standards.

What “Combined Type” ADHD Means
The “combined type” designation in F90.2 refers to individuals who meet the diagnostic criteria for both inattentive and hyperactive-impulsive presentations of ADHD. This means they exhibit a significant number of symptoms from both categories, such as:
Inattentive Symptoms:
- Difficulty sustaining attention in tasks or play
- Easily distracted
- Forgetful in daily activities
- Trouble organizing tasks
- Avoids or dislikes tasks requiring sustained mental effort
Hyperactive-Impulsive Symptoms:
- Fidgets or squirms in seat
- Leaves seat in situations when remaining seated is expected
- Runs about or climbs excessively in situations where it is inappropriate
- Difficulty playing or engaging in leisure activities quietly
- Talks excessively
- Blurts out answers before questions have been completed
- Difficulty waiting their turn
- Interrupts or intrudes on others
For a diagnosis of ADHD combined type (F90.2), these symptoms must be persistent, present in multiple settings (e.g., home and school), and significantly impair social, academic, or occupational functioning.
Synonyms and Related Terms for F90.2
Understanding related terms can further clarify the meaning of F90.2. Common synonyms include:
- ADHD, combined
- ADHD, combined presentation
- Attention deficit hyperactivity disorder combined
- Attention deficit hyperactivity disorder, combined type
These terms are used interchangeably in clinical practice and medical documentation to refer to the same condition coded as F90.2.
Code History and Context within ICD-10-CM
The consistent code history of F90.2 from 2016 to 2025 indicates its established and unchanging definition within the ICD-10-CM system. It falls under the broader category of F90 Attention-deficit hyperactivity disorders, which also includes:
- F90.0: Attention-deficit hyperactivity disorder, predominantly inattentive type
- F90.1: Attention-deficit hyperactivity disorder, predominantly hyperactive type
- F90.8: Attention-deficit hyperactivity disorder, other type
- F90.9: Attention-deficit hyperactivity disorder, unspecified type
Understanding the placement of F90.2 within this hierarchy helps to contextualize its specific meaning and differentiate it from other ADHD presentations. It’s also important to note the codes adjacent to F90.2 in the ICD-10-CM manual, which relate to other neurodevelopmental and behavioral disorders. This proximity highlights the importance of accurate differential diagnosis in clinical practice.
Conclusion
ICD-10-CM code F90.2 is a vital tool for accurately classifying and documenting Attention-deficit hyperactivity disorder, combined type. Its specificity and consistent application ensure reliable data collection and facilitate appropriate healthcare management for individuals with this condition. For healthcare professionals, coders, and anyone involved in medical documentation, a clear understanding of F90.2 is essential for navigating the complexities of ADHD diagnosis and its place within the broader landscape of medical coding.
