CPT code 62330 represents a lumbar spinal decompression procedure that partially removes the ligamentum flavum with a laminotomy at the first lumbar interspace, performed bilaterally and including epidurography and imaging guidance. This operative code is clinically important because degenerative thickening of the ligamentum flavum is a common contributor to lumbar spinal stenosis and radiculopathy; procedures captured by this code are part of the national surgical management pathway for selected patients with compressive neural elements.

Key payers in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The content addresses how the code is classified and used across typical payer settings and describes the clinical and procedural context relevant to coverage and billing workflows.

Readers will find concise benchmarks and policy-relevant notes on coding scope, typical site-of-service placement (hospital outpatient department and ambulatory surgery centers), and procedural components that distinguish this code from related lumbar decompression entries. The summary highlights common documentation elements tied to the service description and flags when additional codes or modifiers may be applicable. Data not available in the input is noted where specific payer edits, fee benchmarks, or associated taxonomies and ICD-10 diagnoses would normally appear.
