Official Coding Guidelines

Assign O35/O36 only if fetal condition modifies maternal mgmt

e. Fetal Conditions Affecting the Management of the Mother 1) Codes from categories O35 and O36 Codes from categories O35, Maternal care for known or suspected fetal abnormality and damage, and O36, Maternal care for other fetal problems, are assigned only when the fetal condition is actually responsible for modifying the management of the mother, i.e., by requiring diagnostic studies, additional observation, special care, or termination of pregnancy. The fact that the fetal condition exists does not justify assigning a code from this series to the mother’s record.

Inconclusive suspected fetal condition: assign O35/O36/O40/O41

For encounters for suspected fetal condition that are inconclusive following testing and evaluation, assign the appropriate code from category O35, O36, O40 or O41.
