Q01.9
ICD-10-CMThis code represents an unspecified type of encephalocele, which is a congenital neural tube defect characterized by a sac-like protrusion of the brain and the membranes that cover it through an opening in the skull. The severity and specific contents of the sac can vary, but this code is used when that detail is not documented.
Use this code when documentation confirms the presence of an encephalocele but does not specify its type (e.g., occipital, frontal, parietal, sphenoidal). This code is appropriate for initial diagnoses when the specific anatomical location or contents of the herniation are not yet determined or clearly documented.
