Is an ’MDD’ classification sufficient for coding depression?

Homecare Insider, March 28, 2016

No. ICD-10-CM classifies depression under Disorder, depressive, major (MDD), but more information is needed to code to the highest level of specificity. The severity of the illness (mild, moderate, or severe) and occurrence needs to be clearly documented by the provider. If the diagnosis is considered severe, the determination of whether there are psychotic features is required. 

Coding for MDD must also include whether the depression is a single episode or a recurrent episode, because the corresponding category differs—it’s F32 for MDD single episode or F33 for MDD recurrent episode.
