Separate moh Gift?

She doesn’t need anything additional just because she has a different title.

Need to? No.
But if shes gone above and beyond an extra something could be nice. But I also would give anything extra to her in private if that's the case.

My MOH is going on a separate "bachelorette weekend" with me, and she's been a ton of help so far, so I plan to include at least a little something else with her gift, but nothing so big that it'd be too noticeable or obnoxious. If she comes down a day earlier I'll probably also bring her along for a mani pedi when I do mine

I didn't get mine anything different. But some people may give gifts that say their roles on it so the only diff i guess is hers would say moh instead of bridesmaid

My MoH is my best friend, and also single-handedly planned my bachelorette and allowed me to stay with her the night before the wedding. I wanted to get her something extra special. For all the girls, I did short floral PJs, slippers and a face mask. Then for my bridesmaids I shopped smart and got a designer purse, sunglasses or watch on killer sales for $60 - $90.

My MoH got a necklace from Tiffany and an Amazon giftcard.

ETA: I did give my MoH her gifts privately the night before the wedding. My bridesmaids got theirs altogether the morning of the wedding as we gathered to get ready.

That is up to you. I chose to get my MOH a necklace in addition to the bridesmaid's gifts, since she did so much planning my bachelorette and helping with appointments.
