Complete code families applicable to F90.9
When to use each related code
| Description | When to use |
|---|---|
| Neurodevelopmental disorder marked by inattention, hyperactivity, and impulsivity. | Diagnose ADHD when inattention and/or hyperactivity-impulsivity impair function across settings, starting in childhood. |
| Oppositional defiant disorder involves a pattern of anger, defiance, and vindictiveness toward authority. | Code ODD for persistent, frequent angry/irritable mood, argumentative/defiant behavior, or vindictiveness toward authority. |
| Conduct disorder involves serious violations of social norms and rules, including aggression and property destruction. | Diagnose conduct disorder if behaviors violate others' basic rights or societal norms, including aggression, theft, or deceit. |
Best-practice checklist
- ✓ADHD diagnosis: DSM-5 criteria documented
- ✓ADHD symptoms: Inattention, hyperactivity, impulsivity details
- ✓ADHD onset: Childhood onset, impairment in 2+ settings
- ✓ADHD differential diagnosis: Ruling out other conditions
- ✓ADHD treatment plan: Medication, therapy, or combined
Common pitfalls to avoid
Coding ADHD requires age-specific documentation. Pediatric criteria differ from adult ADHD diagnostic guidelines.
ADHD frequently coexists with other conditions (anxiety, depression). Accurate coding of all diagnoses impacts reimbursement.
ADHD presents in subtypes (inattentive, hyperactive, combined). Documentation must support the specific subtype coded.
Best-practice tips
- 01ICD-10 F90.x, precise documentation for ADHD subtypes.
- 02Document symptom duration, frequency, severity for accurate coding.
- 03Assess functional impairment across settings (home, school, work).
- 04Differential diagnosis: rule out other conditions, improve CDI.
- 05Medication, therapy details essential for compliance and coding.
Step-by-step checklist
- 1

- 2
Assess symptom duration >6 months and impairment in 2+ settings
- 3
Rule out other medical or psychiatric conditions mimicking ADHD
- 4
Document symptom onset, severity, and functional impact for accurate coding
- 5
Review medication interactions and educate patient/family on safety
Ready-to-paste narrative
Patient presents today with concerns consistent with Attention Deficit Hyperactivity Disorder (ADHD), also sometimes referred to as Attention Deficit Disorder or ADD. Presenting symptoms include inattention, hyperactivity, and impulsivity, impacting academic performance, occupational functioning, and interpersonal relationships. The patient reports difficulty sustaining attention in tasks requiring sustained mental effort, such as lectures, conversations, and reading. They also exhibit symptoms of hyperactivity, including fidgeting, restlessness, and excessive talking. Impulsivity is evident in interrupting others, difficulty waiting their turn, and acting without considering consequences. These symptoms have been present since childhood and are observed across multiple settings (home, school, work). Differential diagnoses considered include anxiety disorders, oppositional defiant disorder, and learning disabilities. The assessment includes a comprehensive review of the patient's medical history, family history, psychosocial history, and behavioral observations. Standardized rating scales, such as the Conners Comprehensive Behavior Rating Scales and the Vanderbilt ADHD Diagnostic Rating Scale, were utilized to gather collateral information and quantify symptom severity. The patient's presentation meets the diagnostic criteria for ADHD, predominantly inattentive presentation, as outlined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). Treatment recommendations include initiation of pharmacotherapy with a stimulant medication, specifically methylphenidate, starting at a low dose and titrating upwards as needed. Cognitive behavioral therapy (CBT) is also recommended to address behavioral modification strategies, improve organizational skills, and develop coping mechanisms for managing ADHD symptoms. Patient education regarding ADHD, medication management, and lifestyle modifications was provided. Follow-up appointment scheduled in four weeks to monitor treatment response, assess medication efficacy and side effects, and adjust treatment plan as indicated. ICD-10 code F90.0 applied for ADHD, predominantly inattentive presentation. CPT codes for evaluation and management services will be determined based on the complexity of the visit. Continued monitoring and adjustments to the treatment plan will be made as necessary to optimize symptom control and improve overall functioning.
Common questions and answers
What are the most effective evidence-based interventions for managing ADHD symptoms in adults presenting with comorbid anxiety?+
Managing ADHD in adults with comorbid anxiety requires a multifaceted approach tailored to the individual's specific needs. Evidence-based interventions include Cognitive Behavioral Therapy (CBT) adapted for ADHD, which addresses both inattention and emotional regulation, and mindfulness-based practices for managing anxiety symptoms. Pharmacotherapy, such as stimulant medication or non-stimulant options like atomoxetine, can also be effective. It's crucial to consider the interplay between ADHD and anxiety when selecting interventions, as some anxiety management techniques may not be suitable for individuals with ADHD. Explore how combined CBT and medication management can improve treatment outcomes for this complex presentation. Consider implementing a stepped-care approach, starting with behavioral interventions and adding medication if necessary, while closely monitoring for symptom changes and medication side effects.
How can clinicians differentiate between inattentive ADHD and sluggish cognitive tempo (SCT) in a differential diagnosis?+
Differentiating between inattentive ADHD and sluggish cognitive tempo (SCT) can be challenging, as they share some overlapping symptoms like slow processing speed and difficulty with sustained attention. However, SCT is characterized by daydreaming, mental fogginess, and low motivation, without the hyperactivity or impulsivity often seen in ADHD. Individuals with SCT tend to be internally preoccupied, while those with inattentive ADHD may be more externally distractible. Neuropsychological testing can be helpful in distinguishing between the two, as SCT often shows deficits in processing speed and executive functions without the same pattern of impairment seen in ADHD. Clinicians should carefully assess the individual's behavioral history, cognitive profile, and functional impairments to arrive at an accurate diagnosis. Learn more about the specific neuropsychological tests that can aid in differentiating between SCT and inattentive ADHD.
Beyond stimulant medication, what alternative pharmacological treatments are available for adult ADHD and what are their efficacy profiles compared to stimulants?+
While stimulant medication is often the first-line treatment for adult ADHD, several non-stimulant alternatives are available for patients who experience intolerable side effects from stimulants or have contraindications. Atomoxetine, a selective norepinephrine reuptake inhibitor, is a common non-stimulant option with demonstrated efficacy in improving attention, hyperactivity, and impulsivity. Guanfacine and clonidine, alpha-2 agonists, are also sometimes used, particularly for individuals with comorbid tic disorders or anxiety. While generally considered less potent than stimulants, these alternatives can offer significant symptom relief for some individuals. It's important to note that the efficacy and tolerability of each medication vary from person to person. Consider implementing a shared decision-making approach with patients to select the most appropriate medication based on their individual needs and preferences, considering factors such as comorbid conditions and potential side effects. Explore the latest research comparing the efficacy profiles of stimulant and non-stimulant medications for adult ADHD.
