ICD-10 codes for ADHD
ADHD codes distinguish presentation when documented: predominantly inattentive, predominantly hyperactive, combined type, or unspecified.
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.
Try AI-assisted extraction with visible medical context
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 use this tool
1
Paste or dictate a de-identified clinical note — a few sentences is enough.
2
Press Get codes. The coding system is fixed on this page.
3
Review each suggested code and its evidence, then copy the codes you agree with.

Evidence stays attached for review.
Paste a clinical note or load an example, then press Get codes. Suggestions appear here with the supporting evidence.
AI suggestions must be reviewed by a clinician before use. Do not paste patient-identifying information into this free tool.

ADHD ICD-10 codes
Start with the primary code, then move to a more specific related code when the documentation supports it.
| Code | Description | System |
|---|---|---|
F90.9 | Attention-deficit hyperactivity disorder, unspecified type | ICD-10-CM |
F90.0 | ADHD, predominantly inattentive type | ICD-10-CM |
F90.1 | ADHD, predominantly hyperactive type | ICD-10-CM |
F90.2 | ADHD, combined type | ICD-10-CM |
Z79.899 | Other long term (current) drug therapy | ICD-10-CM |
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:
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.
