Wiki partial colectomy with open omentopexy

[brightpea]

I could use some help on this case:

My provider performed an open sigmoid colectomy on a pt and, because the pt has a history of enterovesical fistula, he performed an omentopexy to the previous fistula site on the bladder to make sure there was a good fat plane between the anastomosis and the bladder. I'm having a hard time finding a code for an open omentopexy - can anyone help? I'm thinking it would be unlisted 49999.

thanks in advance for helping!

coding the omentopexy as unlisted in case anyone else was wondering the same thing (unless anyone knows something different)
