CPT 29044: Body Cast, Shoulders to Hips and Down One Thigh
CPT code 29044 covers application of a body cast extending from the shoulders to the hips and down one thigh to immobilize the trunk and spine after surgical correction of congenital spinal deformity or repair of traumatic spinal injury. This code captures a specific post‑operative orthopaedic immobilization procedure that supports spinal stability during early healing. Nationally, accurate use of this code matters for correct postoperative billing, appropriate resource planning in surgical and rehabilitation settings, and consistent reporting across payers.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, and how this procedure relates to adjacent codes such as other body‑cast applications. The publication summarizes common payer coverage patterns and the clinical scenarios that justify use of 29044, plus operational considerations for coding teams and billing departments.
The content provides benchmarks for utilization and claims processing trends, highlights policy or coverage considerations relevant to this orthopaedic immobilization service, and clarifies coding relationships with related orthopaedic cast application codes.

Service type: Orthopaedic immobilization procedure performed postoperatively to stabilize the trunk and spine.
-
Typical site of service: Hospital inpatient or outpatient surgical setting, or an ambulatory surgical center, with subsequent care occurring in inpatient or outpatient follow-up visits as clinically indicated.
Clinical & Coding Specifications
Clinical Context
A 14-year-old adolescent male is admitted following a motor vehicle collision with a thoracolumbar spine fracture and associated instability after open reduction and internal fixation to correct traumatic deformity. Postoperatively the orthopaedic team applies a long body cast that extends from the shoulders to the hips and down one thigh to immobilize the trunk and limit motion of the spine while soft tissues and fusion constructs heal. The procedure is performed in the operating room under general anesthesia immediately following spine fixation. The clinical workflow includes intraoperative assessment by the orthopaedic surgeon, cast application by the orthopaedic team or casting technician, verification of fit and pressure points, plain radiographs to confirm alignment within the cast, documentation of time, procedure, and any intraoperative complications, and postoperative nursing instructions for cast care and follow-up with the orthopaedic clinic for removal or transition to a brace.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work required is substantially greater than typical for 29044, documented with supporting operative report. |
26 | Professional component | Use when billing separates the physician professional component (interpretation or professional services) from technical components. |
50 | Bilateral procedure | Use if the cast application is reported bilaterally (not typical for 29044 which is one-thigh); include only if both thighs are included and documentation supports bilateral extent (more consistent with 29046). |
51 | Multiple procedures | Use when 29044 is billed with additional procedures on the same date; sequence and modifier policy per payer applies. |
52 | Reduced services | Use when the procedure is partially reduced or not completed as documented. |
53 | Discontinued procedure | Use when the cast application was started but discontinued for reasons documented in the record. |
62 | Two surgeons | Use when two surgeons from different specialties work together as primary surgeons. |
63 | Procedure performed on infants less than 4 kg | Use if applicable patient meets weight criteria and payer requires this modifier for additional reimbursement or reporting. |
78 | Unplanned return to the operating/procedure room by the same physician following initial procedure for a related procedure during the postoperative period | Use when an unexpected return to OR for cast revision or related corrective procedure occurs. |
79 | (Not listed in provided modifiers) | Data not available in the input. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207X00000X | Orthopaedic Surgery Physician | Primary surgeons who perform spinal fixation and apply postoperative body casts. |
207XX0004X | Orthopaedic Trauma Physician | Specialists managing traumatic spine injuries and postoperative immobilization. |
225100000X | Physical Therapist | Provides postoperative mobility assessment and rehabilitation planning while patient remains immobilized. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
S52.501A | Unspecified fracture of the lower end of right radius, initial encounter for closed fracture | Upper extremity fractures may co-occur with high-energy trauma that also injures the spine; documents comorbid fractures during the same admission requiring coordinated care. |
S52.502A | Unspecified fracture of the lower end of left radius, initial encounter for closed fracture | As above for the left radius; relevant when multiple extremity fractures accompany spinal injury. |
S62.501A | Unspecified fracture of the right hand, initial encounter for closed fracture | Hand fractures are common associated injuries in trauma; affect postoperative rehabilitation and cast handling needs. |
S62.502A | Unspecified fracture of the left hand, initial encounter for closed fracture | As above for the left hand; influences immobilization planning and follow-up. |
M84.431A | Stress fracture, right radius, initial encounter | Represents a nonacute stress fracture that may coexist or be an alternate indication for immobilization; documentation supports need for cast and duration of immobilization. |
