In simple words: This code indicates that the newborn has a health issue due to the mother’s health, but not directly related to the pregnancy itself.

This code is used when a newborn is affected by a maternal condition unrelated to the current pregnancy.It is important to code any current condition the newborn is experiencing first.

Example 1: A newborn presents with jaundice shortly after birth. The mother has a history of autoimmune hepatitis which is determined to be contributing to the newborn's jaundice. The newborn's jaundice would be coded first, followed by P00 to indicate the maternal condition's influence., A newborn is small for gestational age. The mother has chronic hypertension, which may have contributed to the infant's growth restriction. The newborn's low birth weight would be coded first, followed by P00 to indicate the potential impact of the maternal hypertension., A newborn experiences withdrawal symptoms shortly after birth. The mother has a history of substance abuse that predates the pregnancy. The specific withdrawal symptoms would be coded first, followed by P00 to indicate the maternal condition's role.

Documentation should clearly link the newborn's condition to the pre-existing maternal condition.The maternal condition should be documented as unrelated to the present pregnancy. The newborn’s symptoms and related diagnosis should be clearly documented.

** This code is for use on the newborn record only, not the maternal record. This code should not be used if the maternal condition is directly related to the pregnancy.
