Official Description

Closed treatment of patellar fracture, without manipulation

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 27520 refers to the closed treatment of a patellar fracture without the need for manipulation. This procedure is typically indicated when a fracture of the patella, or kneecap, occurs, and the alignment of the bone fragments is stable enough that surgical intervention to realign them is not necessary. In this context, 'closed treatment' means that the fracture is treated without making any incisions or exposing the bone directly. The process begins with obtaining radiographs, or X-rays, to confirm the presence of the fracture and assess its characteristics. A thorough neurovascular examination is conducted to ensure that the nerves and blood vessels surrounding the injury are functioning properly and are not compromised. Following the assessment, the knee is immobilized using a knee brace to provide support and limit movement, which is crucial for the healing process. Patients are also given specific instructions regarding weight-bearing activities to prevent further injury, and they may be provided with crutches or other walking aids to assist with mobility during recovery. This approach aims to facilitate healing while minimizing discomfort and the risk of complications associated with the fracture.

1. Indications

The closed treatment of a patellar fracture without manipulation, as described by CPT® Code 27520, is indicated for patients who present with a fracture of the patella that is stable and does not require surgical intervention to realign the bone fragments. The following conditions may warrant this procedure:

  • Patellar Fracture A confirmed fracture of the kneecap, typically diagnosed through radiographic imaging.
  • Stable Fracture The fracture fragments are in a position that does not necessitate manipulation for proper alignment.
  • Intact Neurovascular Status A neurovascular examination indicates that the nerves and blood vessels around the knee are intact and functioning properly.

2. Procedure

The procedure for the closed treatment of a patellar fracture without manipulation involves several key steps that ensure proper care and management of the injury. The following procedural steps are outlined:

  • Step 1: Radiographic Confirmation Initially, radiographs are obtained to confirm the presence of a patellar fracture. This imaging is crucial for assessing the fracture's characteristics and determining the appropriate treatment plan.
  • Step 2: Neurovascular Examination A comprehensive neurovascular examination is performed to evaluate the integrity of the nerves and blood vessels in the area surrounding the fracture. This step is essential to rule out any potential complications that could arise from the injury.
  • Step 3: Immobilization Once the fracture is confirmed and the neurovascular status is deemed intact, the knee is immobilized using a knee brace. This immobilization is vital for stabilizing the fracture and promoting healing.
  • Step 4: Patient Instructions The patient is then provided with specific instructions regarding weight-bearing limits to ensure that they do not place undue stress on the healing fracture. Additionally, if necessary, the patient is given crutches or other walking aids to assist with mobility during the recovery period.

3. Post-Procedure

After the closed treatment of a patellar fracture without manipulation, patients are expected to follow specific post-procedure care guidelines. The immobilization of the knee with a brace should be maintained as directed to support the healing process. Patients are advised to adhere to the weight-bearing limits provided by their healthcare provider to avoid complications such as displacement of the fracture or additional injury. Regular follow-up appointments may be scheduled to monitor the healing progress through repeat radiographs and clinical evaluations. Patients should also be educated on signs of complications, such as increased pain, swelling, or changes in sensation, which would necessitate immediate medical attention.

54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
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).
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).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
55 Postoperative management only: when 1 physician or other qualified health care professional performed the postoperative management and another performed the surgical procedure, the postoperative component may be identified by adding modifier 55 to the usual procedure number.
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.
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.)
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
