ICD-10 Code F41.3 – Other mixed anxiety disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F41.3 – Other mixed anxiety disorders
What it is
F41.3 identifies mixed anxiety disorders that do not fit a single, more specific anxiety diagnosis. Use it when documentation shows overlapping anxiety symptoms and the record does not name a better-defined disorder.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include persistent worry, nervousness, tension, restlessness, and related anxiety symptoms that occur together without a clearer single diagnosis.
When to use this code
Use F41.3 when the provider documents a mixed anxiety condition or comparable wording and does not specify panic disorder, generalized anxiety disorder, or another more precise code. It is also appropriate when the note states anxiety symptoms are mixed and further detail is unavailable. Check documentation if the record is unclear.
Do not use for
Do not use this code when the documentation supports a more specific anxiety disorder, such as panic disorder or generalized anxiety disorder. Do not assign it for symptoms alone without a diagnosis.
Coding tip
Query for the exact anxiety diagnosis if the note says only “anxiety” or “mixed anxiety” without enough detail.
