I certainly would not bill V22.2 as that means it's totally unrelated to the pregnancy. You are screening for a viable pregnancy so look at V28.89. If she has symptoms of a spontaneous loss, link those to the E&M code. It will also depend on the gestational age. If it's too soon you are doing a routine antenatal screening, V28.89. If she's had a confirmatory HCG and now is not growing or her hormone levels are not increasing appropriately, and there is no heartbeat your provider may call it a loss and you would code the 632. Hope this helps.
