Official Description

Application, cast; elbow to finger (short arm)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 29075 refers to the application of a short arm cast, specifically designed to cover the area from the elbow to the fingers. This procedure is essential for immobilizing various injuries and conditions affecting the distal forearm and wrist. The process begins with the application of a stockinette, which serves as a protective layer over the skin. Following this, padding is added to provide cushioning and comfort. The next step involves the use of a plaster or fiberglass roll, which is first immersed in water to activate its setting properties. After saturating the material, any excess water is gently squeezed out to ensure optimal application. The saturated plaster or fiberglass is then wrapped around the arm, typically starting from the distal (farthest from the body) to the proximal (closest to the body) aspects. This technique allows for a secure fit that conforms to the natural contours of the arm. The final step involves smoothing and molding the cast to ensure it is comfortable and effective in immobilizing the affected area. The short arm cast is particularly useful for treating distal forearm fractures, wrist sprains, carpal fractures, and certain metacarpal fractures. Additionally, variations such as the thumb spica cast are utilized for specific injuries, including scaphoid fractures and some thumb fractures, highlighting the versatility of this casting technique in orthopedic care.

1. Indications

The application of a short arm cast, as described by CPT® Code 29075, is indicated for several specific conditions and injuries affecting the forearm and wrist. These include:

  • Distal Forearm Fractures - These fractures occur in the lower part of the forearm, typically involving the radius or ulna bones.
  • Wrist Sprains - Injuries to the ligaments in the wrist that can result from falls or sudden twists.
  • Carpal Fractures - Fractures that occur in the small bones of the wrist, often due to trauma or impact.
  • Metacarpal Fractures - Fractures of the long bones in the hand that can occur from direct blows or falls.

2. Procedure

The procedure for applying a short arm cast involves several detailed steps to ensure proper immobilization and support of the injured area. The steps are as follows:

  • Step 1: Preparation of the Area - The first step involves preparing the arm for casting. A stockinette is applied over the area that will be casted, providing a protective barrier between the skin and the cast material.
  • Step 2: Padding Application - After the stockinette is in place, padding is added over it. This padding serves to cushion the arm and protect the skin from irritation caused by the cast material.
  • Step 3: Saturation of Casting Material - A roll of plaster or fiberglass is then immersed in water to activate its setting properties. It is crucial to ensure that the material is fully saturated for optimal application.
  • Step 4: Excess Water Removal - Once saturated, any excess water is gently squeezed out of the plaster or fiberglass. This step is important to prevent dripping and ensure a clean application.
  • Step 5: Wrapping the Cast - The saturated plaster or fiberglass is wrapped around the arm, typically starting from the distal aspect and moving towards the proximal aspect. This technique allows for a secure fit that conforms to the arm's shape.
  • Step 6: Smoothing and Molding - Finally, the cast is smoothed and molded to ensure it fits comfortably and effectively immobilizes the affected area. This step is essential for both the comfort of the patient and the efficacy of the cast in supporting the healing process.

3. Post-Procedure

After the application of the short arm cast, several post-procedure care considerations are important for optimal recovery. Patients are typically advised to keep the cast dry and avoid submerging it in water. Regular monitoring for any signs of complications, such as increased pain, swelling, or changes in skin color, is essential. Follow-up appointments may be scheduled to assess the healing process and determine when the cast can be safely removed. Patients should also be educated on the importance of not inserting objects into the cast to avoid skin irritation or injury. Overall, proper post-procedure care is crucial for ensuring a successful recovery and minimizing the risk of complications.

58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
GP Services delivered under an outpatient physical therapy plan of care
KX Requirements specified in the medical policy have been met
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
