ICD-10 Code F30.13 – Manic episode, severe, without psychotic symptoms (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F30.13 – Manic episode, severe, without psychotic symptoms
What it is
F30.13 identifies a severe manic episode without psychotic features. Use it when the patient has a marked, sustained mood elevation or irritability with clear functional impairment, but no hallucinations or delusions are documented.
Clinical signs
Typical findings include decreased need for sleep, pressured speech, racing thoughts, increased activity, and poor judgment. Clinical features vary; refer to documentation, and confirm that psychotic symptoms are absent.
When to use this code
Use this code when the record documents a severe manic episode and the clinician specifies that psychosis is not present. It fits inpatient, emergency, or outpatient encounters where mania is the primary diagnosis and severity is clearly stated. Check documentation if severity or psychotic status is unclear.
Do not use for
Do not use F30.13 if hallucinations, delusions, or other psychotic features are documented. Also avoid it when the episode is hypomanic, mixed, or when the chart does not support severe mania.
Coding tip
Assign F30.13 only when both “severe” and “without psychotic symptoms” are explicitly supported in the note.
