What F90.0 covers
F90.0 is for ADHD in which inattention is the main feature and hyperactive-impulsive symptoms are not prominent. The tabular includes the DSM wording, ADHD predominantly inattentive presentation. The presentation is the clinician's call.
Pediatrics, psychiatry and behavioral health use it, for children and adults alike. F90.2 is combined type, F90.1 predominantly hyperactive type and F90.9 unspecified type. Older notes that say "ADD without hyperactivity" index to F98.8, not F90.0, so check the wording.
Billing and coding notes
The F90 excludes2 list covers anxiety disorders, mood disorders, pervasive developmental disorders and schizophrenia. Those can be coded with F90.0 when the clinician documents both.
Code from the presentation in the current note. If the record says ADHD with no presentation, use F90.9 rather than assuming inattentive type.

Questions about F90.0
Is F90.0 the code for ADD?
For ADHD, predominantly inattentive presentation, yes. A note that says attention deficit disorder without hyperactivity indexes to F98.8, so code what the clinician wrote.
Can F90.0 and F41.1 be coded together?
Yes. Anxiety disorders are an excludes2 under F90, so both can be reported when both are diagnosed.
