Official Description

Application of short leg splint (calf to foot)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The application of a short leg splint, designated by CPT® Code 29515, is a procedure aimed at stabilizing injuries to the lower extremity, specifically from the calf to the foot. This type of splint is crucial in managing conditions that require immobilization to promote healing and prevent further injury. The splint works by decreasing movement in the affected area, thereby providing essential support to the posterior aspect of the leg. The process begins with the application of a stockinette, which serves as a protective layer over the skin. Following this, padding is added to enhance comfort and protect the underlying tissues. The splint itself is created using plaster sheets that are cut to the appropriate length and then immersed in water to become pliable. After excess water is removed, the plaster is carefully applied to the posterior side of the leg, where it is smoothed and molded to ensure a secure fit. Finally, an elastic bandage is wrapped around the leg to hold the splint in place, ensuring that it remains effective in immobilizing the injury. For procedures requiring a longer splint that extends from the thigh to the ankle or toes, CPT® Code 29505 should be utilized instead.

1. Indications

The application of a short leg splint (CPT® Code 29515) is indicated for various conditions that necessitate immobilization of the lower leg. These indications may include:

  • Fractures of the lower leg bones, such as the fibula or tibia, where stabilization is required to promote healing.
  • Severe sprains or strains of the ankle or foot that require support to prevent further injury during the healing process.
  • Soft tissue injuries that necessitate immobilization to reduce pain and swelling.
  • Post-operative care following surgical procedures on the lower leg or foot, where a splint is needed to protect the surgical site.

2. Procedure

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

  • Step 1: Preparation - The patient is positioned comfortably, and the affected leg is exposed. A stockinette is selected based on the size of the leg and is applied over the entire leg, ensuring that it covers the skin adequately to protect it from the splint material.
  • Step 2: Padding - After the stockinette is in place, padding is applied over the stockinette. This padding is crucial as it provides cushioning and comfort, preventing the splint from directly contacting the skin, which could cause irritation or pressure sores.
  • Step 3: Plaster Preparation - Plaster sheets are cut to the appropriate length, typically extending from the calf to the foot. These sheets are then immersed in water to activate the plaster, making it pliable for application. Once saturated, excess water is gently squeezed out to prevent dripping.
  • Step 4: Application of Plaster - The wet plaster sheets are carefully applied to the posterior aspect of the leg. The practitioner smooths and molds the plaster to conform to the shape of the leg, ensuring that it provides adequate support while maintaining comfort.
  • Step 5: Securing the Splint - Once the plaster has been applied and shaped, an elastic bandage is wrapped around the leg to secure the splint in place. This bandage helps to hold the plaster firmly against the leg, preventing any movement that could compromise the healing process.

3. Post-Procedure

After the application of the short leg splint, the patient is advised on post-procedure care to ensure optimal healing. This includes monitoring the splint for any signs of loosening or discomfort. Patients should be instructed to keep the splint dry and avoid submerging it in water. Regular follow-up appointments may be necessary to assess the healing process and to make any adjustments to the splint if required. Additionally, patients should be educated on signs of complications, such as increased pain, swelling, or changes in skin color, which may indicate issues that need to be addressed promptly.

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.
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.
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
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.)

76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
95 Synchronous telemedicine service rendered via a real-time interactive audio and video telecommunications system: synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that would be sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction. modifier 95 may only be appended to the services listed in appendix p. appendix p is the list of cpt codes for services that are typically performed face-to-face, but may be rendered via a real-time (synchronous) interactive audio and video telecommunications system.
