The F90.2 diagnosis code is a critical component of the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) system. Specifically, F90.2 is used to classify Attention-deficit hyperactivity disorder, combined type. This code is essential for medical billing, electronic health records, and tracking health statistics related to ADHD.
In the realm of medical coding and diagnosis, accuracy is paramount. The F90.2 code provides a standardized way to document and categorize cases of ADHD where both inattentive and hyperactive-impulsive symptoms are significantly present. Let’s delve deeper into what F90.2 entails and its implications for diagnosis and record-keeping.
What is the F90.2 Diagnosis Code?
F90.2 is a billable and specific code within the ICD-10-CM system. This means it’s not only used for diagnostic purposes but also for reimbursement claims. When a healthcare provider submits a claim for services related to a patient with combined type ADHD, the F90.2 code clearly indicates the diagnosis.
The 2025 edition of ICD-10-CM F90.2 became effective on October 1, 2024. It’s important to note that this code has been consistently used since the ICD-10-CM system was implemented in the United States. The stability of this code over the years—from 2016 through 2025 without changes—highlights its established place in the diagnostic framework. This version, F90.2, is the American ICD-10-CM version, and it’s worth noting that international versions of ICD-10 F90.2 might have variations.
Applicable Terms for F90.2
The ICD-10-CM system clarifies the application of codes by listing “Applicable To” terms. For F90.2, the applicable term is “Attention-deficit/hyperactivity disorder, combined presentation.” This phrasing emphasizes that the code is used when a patient exhibits a combination of both inattentive and hyperactive-impulsive symptoms, meeting the diagnostic criteria for ADHD combined type.
Synonyms for F90.2
To further clarify the meaning of F90.2, several approximate synonyms are associated with this code:
- Adhd, combined
- Adhd, combined presentation
- Attention deficit hyperactivity disorder combined
- Attention deficit hyperactivity disorder, combined type
These synonyms are helpful in understanding the common language used when referring to this specific type of ADHD. They reinforce that F90.2 is the designated code for cases where both inattentive and hyperactive-impulsive symptoms are prominent.
F90.2 and Diagnostic Related Groups (DRGs)
ICD-10-CM codes are often grouped within Diagnostic Related Groups (MS-DRG) for the purpose of hospital reimbursement and statistical analysis. F90.2 falls within specific DRGs, which are used to classify clinically similar cases and estimate hospital costs. Understanding the DRG grouping related to F90.2 can be important for healthcare administrators and billing professionals. You can utilize tools to Convert F90.2 to ICD-9-CM if needed for historical data comparison or systems still utilizing ICD-9-CM.
Code History of F90.2
The code history of F90.2 is straightforward. It was introduced as a new code in 2016 when ICD-10-CM was fully adopted in the United States (effective October 1, 2015). Since then, and through the 2025 edition, there have been no changes to the F90.2 code. This stability indicates a consistent and well-defined diagnostic category within the ICD-10-CM system. The lack of revisions from 2017 to 2025 underscores its established and accepted use in medical classification.
Context within ICD-10-CM
To understand F90.2 fully, it’s helpful to see its context within the ICD-10-CM code set. It resides within the section F90-F98 which covers “Behavioral and emotional disorders with onset usually occurring in childhood and adolescence.” Specifically, F90 is the parent category for “Attention-deficit hyperactivity disorders.”
The codes adjacent to F90.2 provide further context:
- F90.0: Attention-deficit hyperactivity disorder, predominantly inattentive type
- F90.1: Attention-deficit hyperactivity disorder, predominantly hyperactive type
- F90.2: Attention-deficit hyperactivity disorder, combined type (the focus code)
- F90.8: Attention-deficit hyperactivity disorder, other type
- F90.9: Attention-deficit hyperactivity disorder, unspecified type
These adjacent codes illustrate the different presentations of ADHD that are classified within ICD-10-CM, highlighting F90.2’s role in specifically identifying the combined presentation.
Reimbursement and ICD-10-CM
Finally, it’s critical to remember that reimbursement claims with a date of service on or after October 1, 2015, require the use of ICD-10-CM codes. This includes F90.2. The transition to ICD-10-CM was a significant change, and using the correct codes like F90.2 is essential for accurate billing and processing of healthcare claims.
Understanding the F90.2 diagnosis code is crucial for anyone involved in medical coding, billing, healthcare administration, or clinical practice related to ADHD. Its specific definition, consistent application, and place within the ICD-10-CM system ensure accurate and standardized communication about combined type Attention-deficit hyperactivity disorder.
