QX Modifier For Anesthesia – ZMB

Modifiers in medical billing are two-digit codes appended to a CPT (Current Procedural Terminology) or HCPCS (Healthcare Common Procedure Coding System) code to provide additional information about the service rendered. These modifiers help convey specific circumstances related to the procedure or service.

If there have been updates or changes to the coding system since my last update, it's advisable to check the latest resources provided by authoritative sources such as the American Medical Association (AMA), Centers for Medicare & Medicaid Services (CMS), or other relevant coding authorities. Additionally, consulting with a certified medical coder or billing specialist can offer the most accurate and up-to-date information for your specific situation.
