CPT 01992: Anesthesia for Nerve Block or Injection, Prone/Supine
CPT code 01992 identifies anesthesia services rendered when an anesthesiology provider manages anesthesia for a patient undergoing a diagnostic or therapeutic nerve block or injection performed by another clinician, with the patient in a prone or lying-flat position. This code matters nationally because it documents a distinct anesthesia service tied to procedural positioning and a separate performing clinician, affecting billing workflows, procedural documentation, and payer adjudication across care settings. Key payers in typical analyses include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find a concise overview of the code’s clinical scope and service context, comparisons to closely related anesthesia and injection codes, common associated diagnoses, and the set of modifiers and payer considerations commonly reported with this service. The publication also outlines typical sites of service and related procedure codes that clinicians and billers commonly reference when reporting anesthesia for nerve blocks and injections performed by another provider.
