How would I code "fetal persistent umbilical vein"? I’m not sure if this is a complication or more of an observation. I’ve tried researching and can’t seem to find an answer (if this is abnormal). Not listed in coding book Index as such.

Pt in third trimester is in for routine OB visit and ultrasound review.

Assessment/Plan:
1. Fetal persistent right umbilical vein — limited fetal echo. Consideration of neonatal echo is recommended.
2. AGA — EFW 22% at 35 weeks.

BTW, a co-worker tells me not to code fetal conditions UNLESS they affect management of mother’s care (e.g., further workup is planned, which is not the case here).

So this is a two-part question: Do I code it, and if yes, what code do I use?

Thank you! I appreciate any suggestions.
