CPT 01130: Anesthesia for Body Cast Application or Revision
CPT code 01130 denotes anesthesia services provided during body cast application or revision, a procedure used to immobilize large segments of the body with a plaster shell. This code is relevant nationally because body cast procedures require specialized anesthesia care for positioning, airway management, and prolonged immobilization, and they intersect with broader perioperative anesthesia policy and payment practices. Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise overview of clinical context for the code, common sites of service, and the payer coverage landscape. The publication outlines typical use cases for the code, common accompanying diagnoses encountered in clinical practice, and related anesthesia service considerations. It also highlights how this code fits into anesthesia service lines and how it may interact with anesthesia billing workflows. The content is intended for billing professionals, anesthesiology clinicians, and policy analysts seeking a national-level briefing on the purpose and application of CPT code 01130.

Billing Code Overview
CPT code 01130 describes anesthesia services for body cast application or revision. The service involves administering anesthesia while a provider applies a full plaster body cast that encloses the patient or performs a revision of an existing body cast when clinical needs require reapplication or modification.
Service type: Anesthesia for orthopedic immobilization procedures
Typical site of service: Operating room or procedure suite where anesthesia and immobilization for major casting procedures are performed.
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult admitted to an inpatient orthopedic or pediatric service with unstable spine or pelvic fractures (e.g., S32.9XXA) or a pathological fracture (M84.48XA) who requires application or revision of a full body plaster cast to immobilize the torso and pelvis. The patient presents preoperatively for anesthesia evaluation with uncontrolled pain (M54.5), prior spine surgery complications such as postlaminectomy syndrome (M96.1), or degenerative changes (M47.819) that increase anesthetic complexity. The clinical workflow: pre-anesthesia assessment and airway evaluation; informed consent for anesthesia; perioperative optimization of analgesia and hemodynamics; induction of general endotracheal anesthesia or monitored anesthesia care depending on mobility and procedure complexity; positioning and padding for prolonged supine/prone casting; intraoperative monitoring and management of fluids, ventilation, and pain control; emergence and transfer to post-anesthesia care unit (PACU) with documentation of anesthesia time, techniques, and any complications. For cast revision, the workflow includes review of prior casts and surgical/anesthesia history, consideration of prolonged procedure time or reoperation-related risks, and coordination with orthopedics/trauma team for intraoperative imaging and neurovascular checks.
Coding Specifications
- The following modifiers are most clinically relevant to anesthesia for body cast application or revision. Use only when supported by documentation.
| Modifier | Description | When to Use |
|---|---|---|
23 | Unusual Anesthesia | Use when general anesthesia is medically necessary for a procedure that is usually done with local/monitored anesthesia (e.g., patient agitation, inability to cooperate for cast application). |
50 | Bilateral Procedure | Use when identical casting procedures are performed bilaterally and payor requires bilateral reporting (rare for full body cast but applicable if separate bilateral extremity casts billed). |
52 | Reduced Services | Use when anesthesia services are intentionally reduced or limited compared with usual full service (e.g., abbreviated case). |
53 | Discontinued Procedure | Use when anesthesia is discontinued due to patient condition or intraoperative cancellation prior to intended completion. |
54 | Surgical Care Only | Use when the anesthesiologist provides only intraoperative services and another clinician manages pre/postoperative anesthesia care; document handoffs. |
55 | Postoperative Management Only | Use when the anesthesiologist provides only postoperative pain management or critical care related to the anesthesia episode. |
62 | Two Surgeons | Use when two surgeons are required concurrently for the procedure and documentation supports simultaneous distinct surgical roles affecting anesthesia complexity. |
78 | Return to OR for Related Procedure | Use when the patient returns to the operating room for a related procedure during the postoperative period and anesthesia is provided for the return case. |
AA | Anesthesia by Anesthesiologist | Use when services are personally performed by a physician anesthesiologist (per payor reporting requirement). |
AD | Medical Supervision by Anesthesiologist | Use when an anesthesiologist medically supervises CRNAs for more than four concurrent anesthesia cases. |
AS | Physician Assistant Anesthesiologist | Use when a physician anesthesiologist assistant provides the anesthesia service where recognized by payor. |
QK | Medical Direction of Two or More CRNAs/Anesthetists | Use when an anesthesiologist directs multiple CRNAs and documents required elements for medical direction. |
QS | Monitored Anesthesia Care (MAC) | Use when MAC is provided instead of general anesthesia and documentation supports MAC level care. |
QX | CRNA Service with Medical Direction (QZ/QX/QY set) | Use when a CRNA performs services under medical direction by an anesthesiologist and payor requires QX reporting. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207L00000X | Anesthesiology | Physician anesthesiologists who provide general/regional anesthesia for body cast procedures. |
367500000X | Certified Registered Nurse Anesthetist | CRNAs who administer anesthesia or MAC, frequently in orthopedics/trauma settings. |
207LC0200X | Critical Care Medicine (Anesthesiology) | Anesthesiologists with critical care expertise who manage high-acuity patients requiring complex perioperative support. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
S32.9XXA | Fracture of unspecified part of lumbar spine and pelvis, initial encounter | Indicates trauma-related instability or pain necessitating immobilization with a body cast and perioperative anesthesia management. |
M84.48XA | Pathological fracture, other site, initial encounter | Pathological fractures (e.g., metastatic lesion) may require specialized casting or revision with anesthetic considerations for fragility and comorbidities. |
M96.1 | Postlaminectomy syndrome, not elsewhere classified | Prior spine surgery complications increase anesthetic and positioning risks during body cast application or revision. |
M47.819 | Spondylosis without myelopathy or radiculopathy, site unspecified | Degenerative spine disease contributing to pain and need for immobilization; affects airway/positioning planning. |
M54.5 | Low back pain | Symptom often present in patients requiring torso immobilization; relevant to preoperative pain assessment and postoperative analgesia planning. |
