Appropriate usage of F90.9 for billing
Use this code when ADHD is diagnosed but the documentation lacks the detail to specify the subtype of the disorder.
Use F90.0 if there are 6 or more inattentive symptoms for children or 5 for adults, more inattentive symptoms than hyperactivity symptoms, and they have persisted for at least 6 months. Inattentive symptoms include missed details, not listening, trouble following instructions, difficulty organizing tasks, avoiding tasks that require mental focus, losing things easily, being easily distracted, and being forgetful.
Use F90.1 if there are 6 or more hyperactive-impulsive symptoms for children or 5 for adults, more hyperactive-impulsive than inattentive symptoms, and they have persisted for at least 6 months. Hyperactive-impulsive symptoms include fidgeting, leaving their seat for no reason, restlessness, not being able to play quietly, being constantly in motion, talking excessively, answering questions before they are asked, difficulty waiting their turn, and interrupting others.
Use F90.2 if there are 6 or more hyperactive-impulsive symptoms for children or 5 for adults, and 6 or more inattentive symptoms for children or 5 for adults.
Reviewing each of the hyperactive-impulsive and inattentive symptoms with your patient will help you determine if you should use these codes.
