DSM-5-TR diagnostic criteria summary
F90.1 requires:
- Six or more hyperactivity-impulsivity symptoms, present often for at least six months (the threshold for children; DSM-5-TR sets a lower count for older adolescents and adults).
- Inattention criteria not met over the same six months.
- Symptoms observed before age 12, although the diagnosis may be made later.
- Symptoms in at least two settings (for example, home and school).
- Symptoms beyond what is expected for developmental level, interfering with functioning.
The FY2027 ICD-10-CM tabular list includes "Attention-deficit/hyperactivity disorder, predominantly hyperactive impulsive presentation" under F90.1.

Differential diagnosis
- F90.0 Predominantly Inattentive Type or F90.2 Combined Type, when inattention meets threshold.
- F90.9 Unspecified Type, when the presentation has not been established.
- Anxiety disorders, where restlessness tracks worry rather than a lifelong pattern.
- Bipolar disorder, where increased activity occurs in distinct episodes; see Bipolar I (F31.-).
- Trauma or PTSD, hyperarousal and irritability after trauma.
- Medical causes, including sleep-disordered breathing, lead exposure, iron deficiency, and traumatic brain injury.
Common comorbidities
ADHD often co-occurs with disruptive behaviour, learning disorders, sleep problems, anxiety, and depression (NIMH). Pair an ADHD measure with age-appropriate anxiety and depression screens so co-occurring conditions are captured and coded separately.
Documentation patterns
- Initial assessment: parent and teacher rating forms (or ASRS for adults), symptom counts in both groups, the settings where symptoms appear, and evidence of onset before age 12.
- Follow-up visits: repeat the same rating scale to track response to treatment, and record whether inattention has come to meet threshold, which would move the code to F90.2.
