Brief Answer:
Bipolar disorder not otherwise specified (NOS).

Detailed Answer:

Hello,

Biploar nos means bipolar disorder not otherwise specified (NOS).
Bipolar disorder NOS is more of category that includes a lot more than an actual type of bipolar disorder. Your doctor may use the classification to document symptoms which are consistent with bipolar disorder but fall short of the criteria needed to make a definitive diagnosis. It presumes that there is a problem and that it will be likely be definitively diagnosed in the future.

So, to summarize, bipolar nos, is a suspicion for bipolar but which has not totally decided as definitive diagnoses, but which will be kept under observation and possibly treatment according to the severity of symptoms for the moment.

Hope this is helpful.
Let me know if you need more clarifications.
