Other chronic maternal circulatory and respiratory diseases affecting fetus or newborn

This code signifies the presence of pre-existing, long-term cardiovascular or respiratory conditions in the mother that have the potential to adversely impact the developing fetus or the newborn's health. These are chronic conditions, not acute issues arising during pregnancy, that pose a risk to the offspring.

Apply this code when documentation indicates a maternal history of chronic heart disease (e.g., congenital heart defects, cardiomyopathy) or chronic respiratory disease (e.g., severe asthma, cystic fibrosis) that is noted as affecting or having the potential to affect the fetus or newborn. This is typically used in conjunction with codes for the specific maternal condition and any resulting fetal or neonatal complications.

• Always sequence this code after the primary diagnosis for the specific maternal chronic circulatory or respiratory condition.
• Ensure documentation explicitly links the maternal condition to a potential or actual effect on the fetus or newborn.
• Do not use for acute maternal conditions or conditions that do not have a chronic nature.
