ICD-10 Code F90.0
Attention-Deficit Hyperactivity Disorder, predominantly inattentive type
What is the code F90.0?
F90.0 is a billable/specific ICD-10-CM code used to denote "attention-Deficit Hyperactivity Disorder, predominantly inattentive type." This code is part of the chapter on mental, behavioral, and neurodevelopmental disorders (F01–F99), specifically within the section of Behavioral and emotional disorders with onset usually occurring in childhood and adolescence (F90–F98).
Detailed description of F90.0

Related and similar ICD-10 codes
- F90.1: Attention-deficit hyperactivity disorder, predominantly hyperactive type
- F90.2: Attention-deficit hyperactivity disorder, combined type
- F90.9: Attention-deficit hyperactivity disorder, unspecified type
Appropriate usage of F90.0 for billing
F90.0 should be used for billing when a physician has documented that a patient exhibits the majority of their ADHD symptoms in the form of inattention, without the significant hyperactive or impulsive behaviors that characterize other types.
Instructional guidelines for providers coding F90.0
Documenting the specific behaviors and symptoms that qualify a patient for this subtype supports code assignment. A comprehensive behavioral assessment, often supported by school reports and parental observations, should be part of the medical record.
ADHD may alternatively be documented as “attention deficit syndrome with hyperactivity” and is included in category F90, Attention-deficit hyperactivity disorders.
F90.0 should be assigned when the attention-deficit hyperactivity disorder has been documented as inattentive presentation or type.
Category F90: “Attention-deficit hyperactivity disorders” has a type 2 exclusion note that is applicable to code F90.0, advising that providers may use codes within this category in conjunction with the following ones:
- Anxiety disorders (F40.–, F41.–)
- Mood [affective] disorders (F30–F39)
- Pervasive developmental disorders (F84.–)
- Schizophrenia (F20.–)
If any of the conditions listed in the type 2 exclusion note have been diagnosed, it is acceptable to use both codes as needed in order to describe the patient's condition fully.
Common pitfalls in coding with F90.0
- Using F90.0 when the patient exhibits significant symptoms of hyperactivity or impulsivity, which might warrant a diagnosis of the combined type (F90.2).
- Inadequate documentation of the inattentive symptoms that justifies the use of this specific code.

Conclusion
The ICD-10-CM code F90.0 is used for accurately documenting ADHD cases where inattention is the predominant issue. Proper use of this code facilitates the correct approach to treatment and management, ensuring that patients receive interventions that are most likely to improve their specific symptoms.
