Elevated HCG May Mean Ectopic Pregnancy

Question: I need a diagnosis code for positive human chronic gonadotropin (HCG) four weeks after an abortion. The ultrasound showed no gestational sac.

Answer: You can try reporting V72.40 (Pregnancy examination or test, pregnancy unconfirmed). You shouldn't use the 639.x codes (Complications following abortion and ectopic and molar pregnancies) because this is not a complication of the abortion.

An elevated HCG along with no gestational sac may be an indication of ectopic pregnancy. Question whether or not this is something the ob-gyn suspects. If so, you've got another reason to report V72.40 when the ob-gyn hasn't confirmed the pregnancy or ruled it out at the time of performing the ultrasound.
