Major depressv disorder, single episode, in partial remis

This diagnosis code signifies a single episode of major depression where the patient's symptoms have significantly improved but a full remission has not yet been achieved. While some depressive symptoms persist, they are no longer severe enough to meet the full diagnostic criteria for a major depressive episode.

Apply this code when a patient has experienced a single major depressive episode and is currently showing improvement, but still exhibits some residual symptoms. Documentation should clearly indicate a prior diagnosis of major depressive disorder, a single episode, and current symptom reduction that does not meet full remission criteria.

• Ensure documentation specifies "single episode" and "in partial remission" to differentiate from recurrent episodes or full remission.
• Do not use this code if the patient has a history of multiple major depressive episodes; instead, consider codes for recurrent major depressive disorder.
• Carefully review provider notes for the severity and duration of current symptoms to confirm partial remission status versus active or full remission.
