ICD-10 codes for ADHD

ADHD codes distinguish presentation when documented: predominantly inattentive, predominantly hyperactive, combined type, or unspecified.

F90.9 billable

Notat writes the note — and suggests these codes

The same FactsContext™ engine that extracts codes here turns the full consultation into a structured clinical note, with each code tied to the sentence that supports it. You review and sign every note.

Paste a note or record audio. Notat’s FactsContext™ engine extracts the raw clinical facts first, then suggests codes from that context so you can inspect the evidence before using anything.

How to choose the right code

Use F90.0, F90.1, or F90.2 when the clinical assessment documents the ADHD presentation. Use F90.9 only when ADHD type is not specified. Medication-management visits may also document long-term drug therapy depending on payer policy.

Documentation example

Adult ADHD medication review. Persistent distractibility, disorganization, and difficulty completing tasks since childhood; hyperactivity minimal. Stimulant effective, no appetite or sleep adverse effects. Assessment: ADHD predominantly inattentive type.

Suggested:

F90.0

Not direct transcript guessing

FactsContext extracts clinical facts first: diagnoses, symptoms, negatives, findings, test results, medications, and plan decisions.

Raw facts stay usable

The clinician can read and reuse the extracted medical context directly, independent of the generated note.

Built for review

AI suggestions are not a substitute for clinician judgment, payer rules, local coding policy, or the official code set.

FAQ

When do I use F90.2?

Use F90.2 when both inattentive and hyperactive-impulsive features are documented as combined type ADHD.

Is F90.9 acceptable?

Yes when ADHD is documented without type, but specificity is better when the presentation is recorded.

Can AI infer ADHD type?

Notat should not invent a type. It extracts the documented presentation and assessment as clinical facts, then suggests the code supported by the note.
