Ambulatory Surgery Center Billing: A Complete Guide

 Ambulatory Surgery Center Billing is the process of coding, submitting, and managing reimbursement claims for surgical procedures performed in an outpatient setting. Ambulatory Surgery Centers (ASCs) provide same-day surgeries that do not require hospital admission, making accurate and efficient billing essential to ensure proper reimbursement and financial stability.
