ICD-10 Code Families
Complete code families applicable to F90.0
When to use each related code
| Description | When to use |
|---|---|
| Inattention without hyperactivity. | Primary inattention, difficulty focusing, poor organization. Use if hyperactivity not clinically significant. |
| Inattention and hyperactivity/impulsivity. | Combined inattention, hyperactivity, and impulsivity. Most common ADHD presentation. |
| Primarily hyperactivity/impulsivity. | Significant hyperactivity and impulsivity, limited inattention symptoms. Less common ADHD presentation. |
Best-practice checklist
- ✓ADD diagnosis: Document inattention symptoms.
- ✓Rule out other causes of inattention (e.g., anxiety, depression).
- ✓ADHD inattentive type: Impairment in multiple settings (school, home, work).
- ✓ICD-10 F90.0, DSM-5 314.00: Specific criteria met documented.
- ✓Functional impact of inattention detailed.
Common pitfalls to avoid
Using unspecified ADHD codes (e.g., F90.9) when clinical documentation supports ADD without hyperactivity (F90.0).
Incorrectly coding combined type ADHD (F90.2) or hyperactive-impulsive type (F90.1) instead of inattentive.
Insufficient clinical documentation to support the diagnosis of ADD without hyperactivity, impacting accurate coding and reimbursement.
Best-practice tips
- 01ICD-10 F90.0, minimize distractions for improved focus during ADD evaluations.
- 02Document inattentive symptoms, ruling out other CDI conditions for accurate ADHD diagnosis.
- 03Standardized ADHD assessment tools improve diagnostic accuracy, ensure compliance, support medical necessity.
- 04Behavioral therapies, like CBT, improve attention management in ADD/ADHD, optimize patient outcomes.
- 05Clear, concise clinical documentation supports medical coding for ADD (F90.0), ensures proper reimbursement.
Step-by-step checklist
- 1

- 2
Rule out other causes: anxiety, depression, learning disabilities, sleep disorders
- 3
Assess impact on daily life: academic, social, occupational impairment documented
- 4
Age of onset criteria met: several symptoms present before age 12
- 5
Symptom duration: inattention present for at least 6 months
Ready-to-paste narrative
Patient presents with primary concerns consistent with Attention Deficit Disorder (ADD), also known as Predominantly Inattentive Type ADHD or ADHD-PI. Clinical evaluation reveals significant inattention as evidenced by difficulty sustaining focus, frequent disorganization, forgetfulness in daily activities, and a tendency to be easily distracted. These symptoms are not better explained by another mental disorder and have been present for at least six months, negatively impacting academic and social functioning. Hyperactive-impulsive symptoms such as excessive fidgeting, interrupting, or difficulty remaining seated are not prominent. Differential diagnoses considered include anxiety disorders, depression, learning disabilities, and other medical conditions. Assessment included a thorough review of patient history, behavioral observation, and standardized rating scales. Current diagnostic impression is ADD without Hyperactivity (ICD-10 F90.0). Treatment plan includes patient and family education regarding ADHD inattentive type, consideration of evidence-based interventions such as cognitive behavioral therapy (CBT) to improve attention and organizational skills, and exploration of potential benefits of medication management for ADHD. Follow-up appointments will focus on monitoring symptom improvement, medication efficacy and side effects if applicable, and ongoing assessment of functional impairment related to inattention. The patient and family were provided with resources for ADHD support groups and educational materials.
Common questions and answers
How to differentiate ADD without hyperactivity (inattentive ADHD) from other conditions presenting with similar symptoms in adults?+
Differentiating ADD without hyperactivity (predominantly inattentive ADHD or PI-ADHD) from other conditions like anxiety disorders, depression, or learning disabilities in adults requires a comprehensive assessment. Consider implementing a multi-pronged approach including: 1. Thorough clinical interviews focusing on the onset, duration, and pervasiveness of inattention symptoms across various life domains. Explore how these symptoms impact the individual's occupational, social, and academic functioning. 2. Standardized rating scales and questionnaires specifically designed to assess adult ADHD, such as the ASRS-v1.1 and the CAARS. 3. Cognitive testing to evaluate executive functions like working memory, attentional control, and processing speed, which can help distinguish inattentive ADHD from learning disabilities. 4. A thorough review of the patient's developmental and medical history to rule out other potential causes of inattention. Learn more about the differential diagnosis of adult ADHD to refine your diagnostic accuracy.
What are the evidence-based best practices for treating adult patients with inattentive ADHD (ADD without hyperactivity) in a clinical setting?+
Evidence-based treatment for adult inattentive ADHD (ADD without hyperactivity or PI-ADHD) typically involves a combination of medication and behavioral therapy. Stimulant medications, such as methylphenidate and amphetamine-based formulations, are often the first-line pharmacological intervention, and many patients benefit from these. Non-stimulant medication options like atomoxetine or guanfacine can be explored if stimulants are contraindicated or ineffective. Consider implementing cognitive behavioral therapy (CBT) techniques specifically adapted for adult ADHD. These interventions often focus on skills training in areas such as organization, time management, and emotional regulation. Explore how mindfulness-based practices can complement traditional CBT approaches by enhancing attentional focus and reducing impulsivity. Regular follow-up appointments to monitor treatment response and adjust medication dosages or therapeutic strategies as needed are crucial for successful management.
What are the long-term effects of undiagnosed and untreated Attention Deficit Disorder (ADD) without hyperactivity in adults, and how can clinicians address this challenge proactively?+
Undiagnosed and untreated Attention Deficit Disorder (ADD) without hyperactivity, also known as predominantly inattentive ADHD, can have significant long-term consequences for adults. These may include increased risks of academic and occupational underachievement, relationship difficulties, higher rates of comorbid mental health disorders like anxiety and depression, and greater likelihood of substance abuse. Clinicians can address this challenge by actively screening for ADHD symptoms in adult patients, especially those presenting with persistent difficulties in attention, organization, or executive functioning. Explore how incorporating validated screening tools, like the ASRS or Wender Utah Rating Scale, into routine clinical practice can facilitate early identification and intervention. Educating patients about the potential long-term impact of untreated ADHD can also encourage them to seek help. Consider implementing collaborative care models that involve mental health professionals, primary care physicians, and other support systems to provide comprehensive and ongoing care for individuals diagnosed with inattentive ADHD.
