Code: F90.0
Description: Attention-deficit hyperactivity disorder, predominantly inattentive type
Context: This code is used for cases where a patient is diagnosed with Attention-Deficit Hyperactivity Disorder (ADHD) predominantly characterized by inattention, rather than hyperactivity or impulsiveness.
Guidelines for Proper Use
- Specific Diagnosis of ADHD Type: Use F90.0 for patients diagnosed with ADHD where the predominant symptoms are related to inattention (e.g., difficulty sustaining attention, forgetfulness, not listening when spoken to directly).
- Accurate Documentation: Ensure the healthcare provider’s documentation clearly specifies the diagnosis of ADHD, predominantly inattentive type. The diagnosis should be based on a comprehensive assessment, including behavioral and psychological evaluations.
- Exclusion of Other ADHD Types: Do not use F90.0 for other types of ADHD, such as the predominantly hyperactive-impulsive type or the combined type. Each type has its specific ICD-10 code.
- Differentiating from Other Conditions: Carefully differentiate the predominantly inattentive type of ADHD from other conditions that may have overlapping symptoms, such as learning disorders or anxiety disorders.
- Compliance with Diagnostic Criteria: Use F90.0 in line with established diagnostic criteria, including the DSM-5 or other relevant guidelines, and adhere to coding standards, including payer-specific requirements.
Common Misuses of F90.0
- Use for Other ADHD Types: Misuse occurs when F90.0 is used for patients with predominantly hyperactive-impulsive symptoms or a combination of inattentive and hyperactive-impulsive symptoms.
- Confusion with Non-ADHD Disorders: Avoid using F90.0 for behavioral or learning issues that do not meet the diagnostic criteria for ADHD, predominantly inattentive type.
- Application to Temporary Attention Issues: Do not use F90.0 for temporary attention difficulties due to situational factors or other transient conditions.
