Summary & Overview
CPT 01935: Anesthesia for Percutaneous Image-Guided Spine Diagnostic Procedures
CPT code 01935 denotes anesthesia for percutaneous image-guided diagnostic procedures on the spine and spinal cord. This code applies when anesthesia services are provided to support minimally invasive diagnostic interventions that rely on imaging guidance. Nationally, accurate coding for these procedures affects anesthesia billing, hospital outpatient and ambulatory surgery center workflows, and proper identification of resources used for spine diagnostic care.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find coverage considerations and payer inclusion, clinical context linking the code to image-guided spinal diagnostic procedures, and related service definitions. The publication outlines common coding relationships and adjacent codes relevant to procedural and imaging support.
The report provides practical benchmarks and policy-relevant context for medical billing and revenue cycle teams, anesthesia departments, and clinical program managers. It summarizes the clinical scope of 01935, typical sites of service, common diagnostic indications for image-guided spinal procedures, and related procedural codes. The content is intended to help coding and compliance teams align documentation with national billing practices and to clarify where 01935 is used in the continuum of spine diagnostic services.
Billing Code Overview
CPT code 01935 describes anesthesia for percutaneous image-guided procedures on the spine and spinal cord; diagnostic. The service covers administration of anesthesia during minimally invasive, image-guided diagnostic procedures involving the spine or spinal cord. The service type is anesthesia for image-guided spinal diagnostic procedures. The typical site of service is an ambulatory surgical center or hospital outpatient department where percutaneous, image-guided spinal diagnostic interventions are performed.
Clinical & Coding Specifications
Clinical Context
A 54-year-old patient with chronic low back pain (M54.5) refractory to conservative care is scheduled for a diagnostic percutaneous, image-guided procedure of the lumbar spine to localize a suspected facet-mediated pain generator. The patient presents to an ambulatory surgical center where pre-anesthesia assessment documents prior response to medications, allergy status, airway exam, and ASA classification. Under fluoroscopic guidance, an interventional pain physician performs diagnostic medial branch blocks using 77003 for imaging guidance and 62323 or 64483 techniques for needle placement and injection. An anesthesiologist or certified registered nurse anesthetist provides monitored anesthesia care or sedation appropriate for a percutaneous image-guided spinal diagnostic procedure. Intra-procedure documentation includes the anesthetic technique, agents and dosages, monitoring, airway management, and any unexpected events. Post-procedure recovery includes pain assessment, neurologic check, and discharge instructions. Billing uses 01935 for anesthesia specific to percutaneous image-guided diagnostic procedures on the spine/spinal cord; relevant modifiers are appended as indicated by clinical circumstances (for example, provider service line, anesthesia medical direction, unusual procedural difficulty, or patient-related intraoperative events). Payers involved may include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare depending on patient coverage.
