Ambulatory surgery coding refers to the coding of surgical procedures performed in an outpatient or ambulatory surgery center (ASC) setting, where patients are treated and discharged on the same day. Accurate coding in this setting requires correct procedure code selection, appropriate modifier application, and compliance with ASC-specific coverage rules, NCCI edits, and packaging policies. Nym’s autonomous medical coding engine supports outpatient and ambulatory surgery coding, ensuring compliant code assignment and proper reimbursement under the ASC payment system.
