For clinicians, accurately documenting Attention-Deficit Hyperactivity Disorder (ADHD), combined type, using the F90.2 ICD-10 code is crucial for effective treatment and proper reimbursement. This specific code requires evidence of both inattentive and hyperactive-impulsive symptoms. To ensure compliance and avoid claim denials, which can be as high as 35% for improperly coded ADHD claims, detailed documentation is paramount. This includes noting at least six symptoms from both categories, their presence before the age of 12, and impairment in two or more settings, such as home and school. Explore how leveraging standardized rating scales like the Vanderbilt and Conners scales can provide objective data to support your clinical judgment and create a robust medical record.
When diagnosing a patient with ADHD, combined type (F90.2), it's essential to screen for common comorbidities that can complicate the clinical picture. According to recent data, a significant percentage of individuals with ADHD also present with other conditions. For instance, Oppositional Defiant Disorder (ODD) is seen in up to 50% of cases, while anxiety disorders and major depressive disorder have a co-occurrence rate of 25-40% and 15-30%, respectively. Recognizing and coding for these co-existing conditions, such as F91.3 for ODD or F41.9 for an unspecified anxiety disorder, is not just good clinical practice; it also ensures a more comprehensive treatment plan and accurate billing. Consider implementing a routine screening protocol for these common comorbidities during the initial diagnostic workup for any patient presenting with ADHD symptoms.
The ICD-10 coding system provides specific codes for the different presentations of ADHD, and understanding the nuances between them is key to accurate diagnosis and billing. While F90.2 is designated for the combined type, F90.0 is used for the predominantly inattentive type, and F90.1 is for the predominantly hyperactive-impulsive type. The table below illustrates the key distinctions:
ICD-10 Code
ADHD Type
Key Symptoms
F90.0
Predominantly Inattentive
Difficulty sustaining attention, easily distracted, forgetful in daily activities.
F90.1
Predominantly Hyperactive-Impulsive
Fidgeting, restlessness, excessive talking, interrupting others.
F90.2
Combined Type
A combination of both inattentive and hyperactive-impulsive symptoms.
This clear differentiation helps in tailoring treatment strategies to the patient's specific needs. For example, a patient with F90.0 might benefit more from cognitive-behavioral therapy focused on organizational skills, while a patient with F90.1 might require interventions targeting impulse control.

To "bulletproof" your claims and minimize the risk of denials, your documentation for an F90.2 diagnosis must be thorough and meet the criteria set by payers. A common pitfall is the overuse of the unspecified ADHD code, F90.9, which is a red flag for auditors and can increase the probability of an audit by 280%. Instead, ensure your clinical notes for F90.2 include a comprehensive clinical assessment that aligns with DSM-5-TR criteria, multi-informant reports from parents, teachers, or employers, and a detailed developmental history. It is also crucial to document the functional impairment caused by the symptoms in various settings. Explore how AI scribes can help you capture all the necessary details during your patient encounters, ensuring your documentation is complete and compliant.
The transition to ICD-11, expected to be fully implemented in the coming years, will bring about significant changes in the classification and coding of ADHD. The new code structure, 6A05, will feature enhanced severity specifiers (mild, moderate, severe), improved recognition of adult ADHD, and better frameworks for identifying comorbidities. These changes are designed to provide a more nuanced and clinically useful classification system. To prepare for this transition, it is advisable to start familiarizing yourself with the new criteria and updating your practice's coding systems and documentation workflows. Consider implementing training for your staff on the new classification criteria to ensure a seamless changeover.
To better understand the practical application of the F90.2 code, consider these scenarios. A 10-year-old boy is brought in by his parents who report that he has been struggling in school. His teacher has noted that he frequently daydreams, has trouble finishing his assignments, and often blurts out answers in class. At home, he is constantly in motion, has difficulty waiting his turn in games, and loses his belongings. After a thorough evaluation, including standardized rating scales and clinical interviews with the child and his parents, you diagnose him with ADHD, combined type. In this case, the F90.2 code would be appropriate. In another example, a 25-year-old woman seeks help for what she describes as "lifelong struggles with focus and organization." She reports a history of academic underachievement despite being bright, and she has recently been put on a performance improvement plan at work for missing deadlines. She also describes feeling restless and fidgety, especially in long meetings. A detailed history reveals that these symptoms have been present since childhood. Following a comprehensive assessment, you diagnose her with ADHD, combined type, and assign the F90.2 code.
In today's digital age, clinicians have a variety of tools at their disposal to enhance the diagnosis and management of ADHD. Electronic health record (EHR) systems can be customized with templates for ADHD assessments, ensuring that all necessary information is captured. Patient portals can be used to administer and score standardized rating scales, saving valuable clinic time. Furthermore, telehealth platforms have made it easier to conduct follow-up appointments and provide ongoing support to patients and their families. For instance, a practice could use a tool like Zapier to automate the process of sending out reminder emails for medication refills or follow-up appointments. Grammarly can be a useful tool for ensuring that clinical notes are clear, concise, and professional. Explore how integrating these and other technologies into your practice can improve efficiency and patient care.
The treatment of ADHD, combined type, is multifaceted and should be tailored to the individual needs of the patient. A combination of medication and behavioral interventions is often the most effective approach. Stimulant medications, such as methylphenidate and amphetamine, are considered first-line treatments and have been shown to be effective in about 75% of cases. Non-stimulant medications, such as atomoxetine, may also be used. In addition to medication, behavioral therapies, including cognitive-behavioral therapy (CBT) and parent training in behavior management, play a crucial role in addressing the core symptoms of ADHD and any co-occurring conditions. It is also important to consider the patient's environment and provide support and accommodations in academic and occupational settings.

What specific documentation is required to support an F90.2 diagnosis and avoid claim denials?
To ensure an F90.2 diagnosis for ADHD, combined type, is accepted by payers, your documentation must be comprehensive and precise. It needs to clearly show that the patient meets the specific criteria, including at least six symptoms of both inattention and hyperactivity-impulsivity for children (five for those 17 and older), with symptoms present for over six months and causing impairment in multiple settings like home and school. Crucially, you must detail this functional impairment and rule out other potential diagnoses. Failing to provide this level of detail, especially evidence of both symptom clusters, is a common reason for claim denials. Consider implementing standardized checklists or EHR templates to ensure all diagnostic and medical necessity criteria are met and documented during every evaluation.
How do I correctly code for F90.2 when a patient also has comorbid conditions like anxiety or ODD?
When diagnosing ADHD, combined type (F90.2), it is critical to also identify and code for any co-occurring conditions, as this is a frequent pain point leading to complex clinical presentations. Conditions like anxiety disorders (F40-F41), mood disorders (F30-F39), or Oppositional Defiant Disorder (ODD) are common. The correct approach is to list F90.2 as the primary diagnosis if it is the main reason for the visit, and then list the ICD-10 codes for any comorbid conditions as secondary diagnoses. This creates a complete and accurate clinical picture that justifies the treatment plan and ensures proper billing. Explore how integrated screening tools within your workflow can help systematically identify and document these common comorbidities.
What is the difference between F90.2 and the unspecified ADHD code F90.9, and when should each be used?
Understanding the distinction between F90.2 (ADHD, combined type) and F90.9 (ADHD, unspecified type) is key for accurate coding. F90.2 is a specific code used when a patient definitively meets the full criteria for both inattentive and hyperactive-impulsive symptoms. In contrast, F90.9 should only be used temporarily when a patient shows clear signs of ADHD, but you do not yet have enough information to specify the subtype. Over-reliance on F90.9 can trigger audits and lead to claim rejections because it suggests an incomplete diagnostic process. Always aim to complete a thorough evaluation to specify the diagnosis as F90.0, F90.1, or F90.2 whenever possible.
