My Gyn/Onc MD performed 58661 laparoscopic right salpingo-oophorectomy and left salpingectomy.
Leaving uterus and left ovary for fertility, possible surrogate pregnancy in future.
If I use -50 modifier reflecting both fallopian tubes were taken, what ICD-10 would I use to reflect left-ovary was retained in patient?
N94.89 doesn't seem right. I'm unclear about N99.83.
I can't use Z31.8_ codes, since that is for 'encounter prior to procedure' and retaining ovary was part of the procedure.

I bill this all the time and I have never used a diagnosis to indicate the other ovary was left in place.

FYI - as a heads up, some carriers rather than -50 want this billed
58661-RT
58661-LT
