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

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

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.
