CPT code 62120 denotes a neurosurgical cranial vault repair procedure in which herniated brain tissue is repositioned and the cranial defect is corrected or reconstructed. This code is used for complex skull repairs following trauma, congenital defects, tumor resection, or prior surgical complications and is clinically significant for institutions managing neurotrauma and cranial reconstructive cases. Nationally, accurate use of this code affects hospital surgical case mix, quality measurement, and reimbursement for high-acuity neurosurgical care.

Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides a centralized reference for coding teams, revenue cycle staff, and clinical leads on expected coding context, typical sites of service, and common clinical indications. Readers will find concise benchmarks where available, summaries of relevant policy or coverage considerations, and clinical context that clarifies when CPT code 62120 applies. The content is intended to support consistent coding, billing oversight, and operational planning for hospitals and ambulatory surgery centers that manage cranial reconstructive surgeries. Data not available in the input for payer-specific rates, associated taxonomies, and ICD-10 diagnosis mappings are noted where applicable.
