In simple words: This code indicates an abnormal change in pregnancy hormone levels (hCG) during early pregnancy, which may suggest problems with the pregnancy.

Inappropriate change in quantitative human chorionic gonadotropin (hCG) in early pregnancy. This condition is characterized by hCG levels that rise, fall, or plateau abnormally in early pregnancy, often indicating an impending miscarriage or other pregnancy complications. It may also be referred to as a biochemical pregnancy or chemical pregnancy.

Example 1: A 30-year-old female presents to her physician with a positive home pregnancy test. Serial hCG levels are drawn, and the results indicate an abnormally slow rise in hCG, suggesting an inappropriate change in hCG in early pregnancy. An ultrasound is performed to confirm an intrauterine pregnancy and evaluate for viability., A 25-year-old female experiences vaginal bleeding and cramping at six weeks of gestation. Her hCG levels initially rise appropriately but then plateau and begin to decline, indicating an inappropriate change in hCG associated with an impending miscarriage., A 35-year-old female with a history of infertility undergoes in vitro fertilization (IVF). After a positive pregnancy test, her hCG levels rise rapidly, suggesting an inappropriate change in hCG. An ultrasound confirms a multiple gestation.

Documentation should include serial serum hCG levels demonstrating the inappropriate change (slow rise, plateau, or decline), along with the corresponding gestational age.Ultrasound findings and other relevant clinical information such as vaginal bleeding, cramping, or abdominal pain should also be documented.
