Code Description

ICD-10 O35.04 is a billable code used to indicate a diagnosis of maternal care for (suspected) central nervous system malformation or damage in fetus, encephalocele.

Key Diagnostic Point:

O35.04 refers to maternal care provided for suspected central nervous system malformations or damage in the fetus, specifically indicating the presence of an encephalocele. An encephalocele is a congenital defect characterized by the protrusion of brain tissue through a defect in the skull, often associated with other neurological anomalies. Maternal care for this condition involves comprehensive prenatal assessment, including advanced imaging techniques such as ultrasound and MRI, to evaluate the extent of the malformation. Genetic counseling is also crucial, as encephaloceles can be linked to chromosomal abnormalities and syndromes. The management plan may include multidisciplinary consultations with maternal-fetal medicine specialists, neurosurgeons, and geneticists to discuss potential outcomes, delivery planning, and postnatal care. The complexity of care increases with the need for ongoing monitoring and potential interventions, making it essential for healthcare providers to document all findings and recommendations thoroughly.
