ICD-10 Code F30.4 – Manic episode in full remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F30.4 – Manic episode in full remission
What it is
This code identifies a past manic episode that is now in full remission. You use it when the manic symptoms have resolved and the patient is no longer meeting criteria for an active episode.
Clinical signs
Clinical features vary; refer to documentation. In full remission, there are no current manic symptoms such as elevated mood, decreased need for sleep, increased activity, or marked impulsivity.
When to use this code
Use F30.4 when the record clearly states that a manic episode has ended and the patient is in full remission. It may appear in follow-up or maintenance visits after stabilization. Check documentation for the current status and any ongoing bipolar diagnosis.
Do not use for
Do not use this code for active mania, partial remission, or unspecified mood episodes. If the chart does not clearly document full remission, check documentation before assigning F30.4.
Coding tip
Code the remission status exactly as documented, and confirm whether a separate bipolar disorder code is also required.
