In dx codes related to newborns, at what age is a child considered no longer a newborn re specific diagnoses codes? MCD claims have denied saying the dx is incorrect for child's age. We give outpatient speech therapy, occupational and physical therapy to children under three. We were referred to "Section 2" but have been unable to find the answer there. We can give more detail to get the correct answer if needed. Thanks in advance for your help and for possible reference to the source of the answer.
