F41.9 — 焦慮症，未指明

No, it's generally considered a non-specific diagnosis. Further evaluation is needed to identify the type of anxiety.

One can use the F41.9 code when one cannot pinpoint the patient's specific anxiety disorder, when they meet the criteria for general anxiety disorder but not for any other specific type, and when further investigation or observation is needed to reach a more precise diagnosis.

The healthcare provider must include the following in the patient's medical records: anxiety symptoms, impact of the symptoms, relevant history, clinician's assessment and rational, and any plans for further evaluation or treatment.
