With ICD-9-CM, when documentation for MDD did not specify single episode or recurrent, the subcategory 296.2x gave the option "single episode or unspecified" in the notes after the subcategory in the tabular. With ICD-10-CM, the unspecified option has been removed. When documentation does not state if the duration is for a single episode or recurrent, but does support coding to a specific severity (i.e. mild), would you select F32.0, major depressive disorder, single episode, mild or would you revert to F32.8 or F32.9 instead?

There are no guidelines providing direction, and I cannot find any reputable opinion write up online. Your help is appreciated. Thanks in advance!:cool:

Major Depression

If you index major depression with severity w/o episode of care, it will default to MDD. Single Episode, mild or any other documented severity.
