Unspecified spina bifida with hydrocephalus

This code describes a congenital neural tube defect where the spinal column is incompletely closed, and the specific type of spina bifida is not documented. It is further characterized by the co-occurrence of hydrocephalus, a condition involving an abnormal accumulation of cerebrospinal fluid within the brain's ventricles. This combination often leads to neurological deficits and developmental challenges.

Use this code when the patient's medical record clearly indicates a diagnosis of spina bifida with co-occurring hydrocephalus, but the specific anatomical type of spina bifida (e.g., myelomeningocele, meningocele) is not specified by the provider. Documentation should confirm both conditions are present and the lack of further specificity regarding the spina bifida type.

• Avoid using this code if the specific type of spina bifida is documented; instead, code to the highest level of specificity.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity impacting care.
• Ensure documentation explicitly states "unspecified spina bifida" or lacks sufficient detail to classify a more specific type, in conjunction with hydrocephalus.
