ICD-9 code for Hyperemesis gravidarum vs N/V in pregnancy

Good day,

Your coding opinions with supporting documentation/regs to support your response, please..

25 year old 37 week pregnant female presents to clinic with N/V for 3 days. IV fluids given and Provider documents as final dx:

"37 week pregnant female with dehydration, undelivered.

What ICD-9 codes would you use and what is your rationale?


Thanks,

Sheila
