We had a pt (insufficient prenatal care) who was 21 weeks pregnant with twins and delivered. Twin A- delivery of a nonviable twin at 21 weeks and twin B- Dr. describes the delivery as a dilation and evacuation. The question is at what stage can you bill a delivery for twin A? We cannot find a specific gestation age.. does the baby have to be over 28 weeks or just 20 or does it matter? Any insight would help!! Thank you!
