Code Description

ICD-10 F33.42 is a billable code used to indicate a diagnosis of major depressive disorder, recurrent, in full remission.

Key Diagnostic Point:

Major depressive disorder (MDD) is characterized by recurrent episodes of depression that significantly impair an individual's ability to function. The recurrent nature of this disorder indicates that the patient has experienced multiple depressive episodes, which can vary in severity and duration. In the case of F33.42, the patient is currently in full remission, meaning they do not exhibit any significant symptoms of depression at the time of assessment. This status is crucial for treatment planning and monitoring, as it indicates that the patient has responded well to previous interventions, which may include psychotherapy, pharmacotherapy with mood stabilizers or antidepressants, and lifestyle modifications. It is essential to document the patient's history of depressive episodes, the duration of remission, and any ongoing treatment to ensure accurate coding and appropriate care management. Regular suicide risk assessments are also vital, as individuals with a history of recurrent depression may still be at risk for suicidal ideation or behavior, even in remission.
