Fun with ICD-9 codes

I came across a situation recently in which a woman was described having mania in bipolar disorder, but was “diagnosed” with 296.2. And the recommended treatment? Venlafaxine (Effexor).

I swear, sometimes doctors themselves don’t even know what to prescribe.

UPDATE:
Okay, maybe I was wrong?

2007 ICD-9-CM Diagnosis 296.2
    Major depressive disorder single episode
        * 296.2 is a non-specific code that cannot be used to specify a diagnosis
        * 296.2 contains 72 index entries
        * View the ICD-9-CM Volume 1 296.* hierarchy

    Alternate Terminology
        * Depressive psychosis, single episode or unspecified
        * Endogenous depression, single episode or unspecified
        * Involutional melancholia, single episode or unspecified
        * Manic-depressive psychosis or reaction, depressed type, single episode or unspecified
        * Monopolar depression, single episode or unspecified
        * Psychotic depression, single episode or unspecified

So it’s totally possible to have a bipolar episode and be depressed? WTF? Am I depressed with bipolar symptoms or am I bipolar with depressive episodes? Ugh, none of this diagnosis stuff makes sense. Glad I’m not a doctor now.

No.
