uterine size vs small or large for dates for ICD10

Misty Posted Mon 07th of December, 2015 16:27:10 PM

Can you please explain the difference with the ICD10 wording for uterine size discrepancy O26.843 and size small or large for dates. My nurses wanted me to get this clarified with the new ICD10 coding. I'm using size small & large for dates for the baby, not sure about the uterine size discrepancy. Would this be used for when their checking exact dates/weeks of baby??

Uterine size discrepancy is a condition whereby size of a gravid uterus is not equal to the gestational age(can be ±2 weeks). It can be larger or smaller than date.
In this, size small for dates meaning is "fundal height is reading smaller than would be expected compared to that of the 'average' pregnancy" and large for dates meaning is "fundal height reads more than 2cm more than would be expected for stage of pregnancy compared to the average" during examination.
O26.843 can be use for Uterine size discrepancy(small & large both).
