CPT® Code 62117

Reduction of craniomegalic skull (eg, treated hydrocephalus); requiring craniotomy and reconstruction with or without bone graft (includes obtaining grafts)

The procedure described by CPT® Code 62117 involves the surgical reduction of a craniomegalic skull, which is characterized by an abnormally large head size often resulting from conditions such as hydrocephalus. In this procedure, the physician performs a craniotomy, which is an operation that involves making an incision in the skull to access the brain. The surgeon carefully separates the individual bones of the skull and removes a portion of the bone to decrease the overall size of the skull. After the necessary adjustments are made, the bones are reattached to restore the skull's structure. In some cases, the physician may utilize bone grafts to aid in the reconstruction process, which involves either using the patient's own bone or donor bone to fill in gaps and ensure proper alignment and stability of the skull. This procedure is critical for alleviating pressure on the brain and addressing any associated neurological issues that may arise from the condition of craniomegaly.
