CPT 00632: Anesthesia for Lumbar Region Procedures, Including Lumbar Sympathectomy
CPT code 00632 represents anesthesia services provided for procedures in the lumbar region, including lumbar sympathectomy. This code is used to report the anesthetic management tied to lumbar surgical interventions and is relevant across inpatient and ambulatory surgical settings nationwide. Accurate reporting of this code supports correct clinical documentation, claims processing, and alignment of anesthesia services with the underlying surgical procedure.
Major national payers in scope include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers can expect an overview of coverage and billing considerations under these payers, common clinical contexts in which 00632 is used, and comparisons to related lumbar anesthesia CPT codes. The publication also outlines typical sites of service and clinical indications commonly associated with lumbar regional anesthesia.
This piece provides clinicians, billing professionals, and policy analysts with a concise reference on the clinical definition and billing role of 00632, its relationship to similar lumbar anesthesia codes, and the payer landscape relevant to national practice.

Billing Code Overview
CPT code 00632 describes anesthesia services for procedures performed in the lumbar region, specifically including lumbar sympathectomy. The service type is regional anesthesia for lumbar surgical procedures, typically delivered in an operating room or surgical suite where lumbar surgical or endovascular procedures are performed. This code denotes provision of anesthesia care tied to interventions focused on the lumbar spine and adjacent structures.
Clinical & Coding Specifications
Clinical Context
A 62-year-old male with chronic lumbar radiculopathy and neurogenic claudication presents for lumbar sympathectomy to treat refractory lower-extremity vasospastic pain and autonomic dysfunction after conservative measures failed. Preoperative evaluation in the ambulatory surgery center documents prior lumbar imaging demonstrating multilevel degenerative changes with L4-L5 disc displacement (M51.26) and moderate lumbar spinal stenosis (M48.06). The anesthesia team (Anesthesiology Physician or Certified Registered Nurse Anesthetist) reviews comorbidities, confirms informed consent, establishes intravenous access, and provides monitored anesthesia care with sedation and regional blockade as indicated. Intraoperative management includes hemodynamic monitoring, positioning for fluoroscopic access to the lumbar sympathetic chain, sterile technique, administration of anesthetic agents, and potential conversion to general anesthesia if required. Post-procedure recovery takes place in the post-anesthesia care unit with focused monitoring for hemodynamic instability and neurologic exam prior to discharge or inpatient admission based on clinical status.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work required is substantially greater than typical for 00632 due to complexity or unusual circumstances. |
23 | Unusual anesthesia: general anesthesia administered when normally not required | Use when general anesthesia is required for 00632 although procedure typically performed with regional or monitored anesthesia. |
50 | Bilateral procedure | Use when bilateral lumbar sympathetic procedures are performed during the same operative session. |
52 | Reduced services | Use when the service for 00632 is partially reduced or discontinued but still performed. |
53 | Discontinued procedure | Use when 00632 is started but terminated due to extenuating circumstances. |
54 | Surgical care only | Use when the reporting clinician provides only the surgical portion and not anesthesia management (rare for anesthesia codes; included for cross-discipline billing contexts). |
55 | Postoperative management only | Use when the clinician provides only postoperative management separate from intraoperative anesthesia services. |
62 | Two surgeons | Use when two surgeons or proceduralists are required and this affects anesthesia planning or duration for 00632. |
78 | Unplanned return to the operating/procedure room by same physician following initial procedure for a related procedure | Use when an unplanned repeat lumbar sympathectomy-related procedure occurs during the global period. |
AA | Anesthesia services performed personally by anesthesiologist | Use when an anesthesiologist personally performs the anesthesia for 00632. |
AD | Medical supervision by a physician; medically directed anesthesia services | Use when an anesthesiologist medically directs qualified anesthesia personnel for 00632 and meets supervision criteria. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | Use when an advanced practice clinician assists with perioperative management affecting billing workflows. |
QK | Medical direction of two, three, or four qualified CRNAs | Use when an anesthesiologist medically directs multiple CRNAs providing 00632. |
QS | Monitored anesthesia care (MAC) service | Use when MAC is provided rather than general anesthesia for 00632. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207L00000X | Anesthesiology Physician | Primary clinician for anesthesia services and medical direction for 00632. |
367500000X | Certified Registered Nurse Anesthetist | Common provider performing anesthesia care, often under medical direction for 00632. |
207LP2900X | Pain Medicine Physician | May perform or collaborate on lumbar sympathectomy for pain indications and coordinate perioperative management. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
M54.5 | Low back pain | Common presenting symptom prompting evaluation and procedures targeting lumbar sympathetic chain when autonomic or vascular contributors are suspected. |
M51.26 | Other intervertebral disc displacement, lumbar region | Disc pathology that can cause radicular pain and may be part of the clinical picture leading to sympathectomy when neuropathic or ischemic features are present. |
M54.16 | Radiculopathy, lumbar region | Nerve root irritation producing radiating leg pain; can coexist with conditions treated by lumbar sympathectomy for refractory pain control. |
M48.06 | Spinal stenosis, lumbar region | Degenerative narrowing contributing to neurogenic claudication and complex pain syndromes considered in procedural planning. |
M47.816 | Spondylosis without myelopathy or radiculopathy, lumbar region | Degenerative spine disease noted on imaging that contextualizes the indication for lumbar sympathectomy in chronic lumbar pain management. |

00635 | Anesthesia for diagnostic or therapeutic lumbar puncture | Related lumbar-region anesthesia services that may occur in the same clinical setting for diagnostic or therapeutic spinal procedures; distinct from sympathectomy-specific anesthesia. |
