Reapplying the H4 visa after 180 days 221g delay

Hello,
I have applied for H4 visa in NewDelhi consulate, got 221g its been six months so far no response, case status and case created date are same as my interview date.
Does reapplying the same visa after 180 days should be okay ?
Do we have to inform abut the 221g in DS 160 form for the below question ?
Have you ever been refused a U.S. Visa, or been refused admission to the United States, or withdrawn your application for admission at the port of entry?
Any one got the visa after adding the 221g details in DS 160 without any issues ?

Did you submit all the requested documents under 221g?

Yes, submitted all the documents with in the same week

You will need to wait to hear back. It is not advisable to reapply with a pending 221g decision.

You may send a follow up email to the consulate processing your case.
