CPT code 62273 denotes an epidural blood patch, a therapeutic procedure that injects a patient’s own blood into the epidural space to seal cerebrospinal fluid (CSF) leaks that cause post-spinal headaches. Nationally, this code is important because it represents a targeted intervention for a relatively common complication of neuraxial procedures — including epidural anesthesia, spinal needle placement, and lumbar puncture — and influences facility and physician billing for neuraxial complication management.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, the typical sites of service where the intervention is performed, and the common billing modifiers associated with the code. The publication summarizes what to expect in terms of coding classification and payer coverage patterns and highlights policy and documentation considerations that affect claim processing.

This overview provides clinicians, billers, and policy staff with operational clarity on when 62273 applies, how it fits into neuraxial complication care pathways, and the practical billing elements to verify when submitting claims to major national payers.
