Attention-deficit hyperactivity disorders (F90) ICD-10-CM
The F90 code range covers attention-deficit hyperactivity disorders with 6 ICD-10-CM diagnosis codes. 5 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- attention deficit disorder with hyperactivity
- attention deficit syndrome with hyperactivity
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the F90 range.
Acromegaly
A condition caused by prolonged exposure to excessive HUMAN GROWTH HORMONE in adults. It is characterized by bony enlargement of the FACE; lower jaw (PROGNATHISM); hands; FEET; HEAD; and THORAX.

About the F90 Code Range
ICD-10 code F90 covers various types of attention-deficit hyperactivity disorders (ADHD), a group of neurodevelopmental conditions identified by patterns of inattention, hyperactivity, and impulsivity. These codes specify different ADHD presentations to guide accurate diagnosis and treatment.
The ICD-10 code for ADHD includes distinct classifications such as F90.0 for predominantly inattentive type, often known as "attention deficit hyperactivity disorder, inattentive presentation," emphasizing issues with focus rather than hyperactivity. F90.1 corresponds to the predominantly hyperactive type, sometimes referred to as "hyperkinesis with developmental delay," highlighting impulsive and hyperactive behaviors. The combined form, F90.2, captures individuals exhibiting both inattentiveness and hyperactivity symptoms. Other specified forms are coded as F90.8 (e.g., undifferentiated attention deficit disorder), while F90.9 includes unspecified or overlapping ADHD presentations, covering diverse terms like child or adult attention deficit disorders and related developmental speech or behavioral challenges. These codes assist healthcare providers and coders in differentiating ADHD subtypes for targeted management.
