P00: Fetus and newborn affected by maternal conditions that may be unrelated to present pregnancy

The group of conditions classified under "Fetus and newborn affected by maternal conditions that may be unrelated to present pregnancy" refers to a set of health issues that newborn babies might face, which are directly linked to certain maternal health problems from any point in the mother's past, not exclusively during the ongoing pregnancy. These maternal conditions may include chronic diseases, infections, or substance use disorders among others, which can affect the fetus' development and overall health. The symptoms in the newborns can widely vary, depending on the specific maternal condition involved and can affect multiple systems in the baby's body. Symptoms may be present at birth or develop as the infant grows. The long-term impact of these conditions can range from mild to severe, affecting the child's growth and development. The progression of these conditions is unpredictable as it's influenced by many factors, including the maternal health status, the infant's health, and the treatment provided.
