Official Description

Radiologic examination, knee; 3 views

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

A radiologic examination of the knee, designated by CPT® Code 73562, involves capturing images of the knee joint through X-ray technology. This procedure specifically includes three distinct views of the knee, which are essential for a comprehensive assessment of the joint's structure and any potential abnormalities. The examination focuses on key anatomical components such as the femur, tibia, fibula, patella, and surrounding soft tissues. X-ray imaging operates on the principle of indirect ionizing radiation, which allows for the visualization of internal body structures by exploiting the varying densities and compositions of different materials, such as human tissue. During the X-ray process, some of the emitted X-rays are absorbed by the denser structures, while others pass through and are captured on a detector, resulting in a two-dimensional representation of the knee's anatomy. This imaging technique is particularly valuable for diagnosing a range of conditions, including but not limited to fractures, dislocations, deformities, degenerative diseases, osteomyelitis, arthritis, foreign bodies, and cysts or tumors. Additionally, knee X-rays can be instrumental in evaluating the alignment of lower extremity bones after fracture treatment. The standard views obtained during this examination include the anteroposterior (AP) view, which captures the knee from front to back, the lateral view, which shows the knee from the side, and the posteroanterior (PA) view, which provides a back-to-front perspective. Variations in joint flexion and the patient's weight-bearing status may also be considered during the imaging process. For procedures requiring fewer views, CPT® Code 73560 is applicable for one or two views, while CPT® Code 73564 is used for a complete examination involving four or more views. Furthermore, CPT® Code 73565 is designated for weight-bearing X-ray examinations of both knees taken on a single film.

1. Indications

The radiologic examination of the knee, coded as CPT® 73562, is indicated for various clinical scenarios where detailed imaging of the knee joint is necessary. The following conditions and symptoms may warrant this procedure:

  • Fractures - To assess the presence and extent of bone fractures in the knee region.
  • Dislocations - To evaluate any dislocation of the knee joint or its components.
  • Deformities - To identify structural deformities in the knee that may affect function.
  • Degenerative Disease - To investigate signs of degenerative conditions such as osteoarthritis.
  • Osteomyelitis - To detect potential infections in the bone surrounding the knee joint.
  • Arthritis - To assess the severity and impact of various forms of arthritis on the knee joint.
  • Foreign Body - To locate any foreign objects that may be present within the knee area.
  • Cysts or Tumors - To identify the presence of cysts or tumors in or around the knee joint.
  • Alignment Assessment - To evaluate the alignment of lower extremity bones following treatment for fractures.

2. Procedure

The procedure for a radiologic examination of the knee using CPT® Code 73562 involves several key steps to ensure accurate imaging and assessment of the knee joint. The following procedural steps are typically followed:

  • Step 1: Patient Preparation - The patient is positioned appropriately, typically seated or lying down, to facilitate optimal imaging of the knee. The technologist may provide instructions regarding the positioning of the leg and any necessary adjustments to ensure the knee is adequately exposed for imaging.
  • Step 2: Anteroposterior (AP) View - The first view taken is the anteroposterior (AP) view, where the X-ray beam is directed from the front of the knee to the back. This view allows for visualization of the knee joint space and alignment of the femur and tibia.
  • Step 3: Lateral View - The second view is the lateral view, which captures the knee from the side. This perspective is crucial for assessing the profile of the knee joint, including the patella and the relationship between the femur and tibia.
  • Step 4: Posteroanterior (PA) View - The final view is the posteroanterior (PA) view, where the X-ray beam is directed from the back of the knee to the front. This view provides additional information about the knee's internal structures and alignment.
  • Step 5: Image Review - After the images are captured, the radiologic technologist reviews them for clarity and completeness. If necessary, additional images may be taken to ensure all relevant aspects of the knee are adequately visualized.

3. Post-Procedure

Post-procedure care following a radiologic examination of the knee is generally minimal, as the procedure is non-invasive and does not typically require recovery time. Patients may resume normal activities immediately after the examination. However, it is essential for patients to follow any specific instructions provided by the healthcare provider regarding the interpretation of results and any necessary follow-up appointments. The radiologist will analyze the images and provide a report detailing findings, which will be communicated to the referring physician for further evaluation and management of the patient's condition.

26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
TC Technical component; under certain circumstances, a charge may be made for the technical component alone; under those circumstances the technical component charge is identified by adding modifier 'tc' to the usual procedure number; technical component charges are institutional charges and not billed separately by physicians; however, portable x-ray suppliers only bill for technical component and should utilize modifier tc; the charge data from portable x-ray suppliers will then be used to build customary and prevailing profiles
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).
FY X-ray taken using computed radiography technology/cassette-based imaging
X5 Diagnostic services requested by another clinician: for reporting services by a clinician who furnishes care to the patient only as requested by another clinician or subsequent and related services requested by another clinician; this modifier is reported for patient relationships that may not be adequately captured by the above alternative categories; reporting clinician service examples include but are not limited to, the radiologist's interpretation of an imaging study requested by another clinician
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.
GC This service has been performed in part by a resident under the direction of a teaching physician
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
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.
Q6 Service furnished under a fee-for-time compensation arrangement by a substitute physician or by a substitute physical therapist furnishing outpatient physical therapy services in a health professional shortage area, a medically underserved area, or a rural area

GW Service not related to the hospice patient's terminal condition
XE Separate encounter, a service that is distinct because it occurred during a separate encounter
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).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) 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.
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.
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.)
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.
