ICD-10 codes for anxiety

Anxiety coding depends on the documented diagnosis pattern. Generalized anxiety disorder, panic disorder, adjustment disorder with anxiety, and unspecified anxiety are not interchangeable.

F41.1 billable

Anxiety ICD-10 codes

Start with the primary code, then move to a more specific related code when the documentation supports it.

F41.1

Generalized anxiety disorder

ICD-10-CM

F41.9

Anxiety disorder, unspecified

ICD-10-CM

F41.0

Panic disorder without agoraphobia

ICD-10-CM

F43.22

Adjustment disorder with anxiety

ICD-10-CM

F40.10

Social phobia, unspecified

ICD-10-CM

Use F41.1 when persistent excessive worry and associated symptoms support generalized anxiety disorder. Use F41.0 when discrete panic attacks are the diagnosis, F43.22 when symptoms are tied to an identifiable stressor and documented as adjustment disorder, and F41.9 only when the anxiety disorder is not specified further.

Six-month history of excessive worry about work and family most days, with poor sleep, muscle tension, and difficulty concentrating. No panic attacks. GAD-7 score 15. Assessment: generalized anxiety disorder; started CBT referral and sertraline discussion.

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.

FAQ

When should I use F41.1 instead of F41.9?

Use F41.1 when the note documents generalized anxiety disorder. F41.9 is for anxiety disorder without enough diagnostic specificity.

How do I code panic attacks?

If the clinician diagnoses panic disorder without agoraphobia, F41.0 is the ICD-10-CM code. Isolated panic symptoms may need different documentation.

Can AI distinguish anxiety diagnoses?

Notat extracts duration, symptom pattern, triggers, and assessment as clinical facts, then suggests codes with the evidence so you can verify the diagnosis before accepting.
