73560

X-ray, knee, 1 or 2 views

The CPT code 73560 describes a radiological examination of the knee joint, encompassing one or two distinct radiographic views. This procedure is typically performed to visualize the bony structures, joint spaces, and surrounding soft tissues of the knee, aiding in the diagnosis of various pathologies including fractures, dislocations, degenerative changes, and effusions. Common views include anteroposterior (AP) and/or lateral views, chosen based on the clinical suspicion and area of interest. The images are acquired using ionizing radiation and subsequently interpreted by a qualified physician.

Clinical Indications

  • Evaluation of acute knee injury (e.g., trauma, fall, sports injury)
  • Suspected fracture or dislocation of the patella, femur, or tibia involving the knee joint
  • Assessment of new or worsening knee pain, especially with weight-bearing or following an inciting event
  • Detection of knee joint effusion, swelling, or soft tissue calcifications
  • Investigation of bony abnormalities, deformities, or alignment issues
  • Monitoring of fracture healing or post-operative status following knee surgery
  • Pre-operative planning for knee procedures or interventions
  • Evaluation of suspected osteoarthritis or other degenerative joint disease in the knee

Procedure Steps

  1. Patient is positioned appropriately for the required radiographic views (e.g., supine for AP, lateral recumbent or standing for lateral views).
  2. The technologist ensures proper alignment of the X-ray tube, patient, and image receptor to accurately capture the knee joint.
  3. Collimation is applied to minimize radiation exposure to surrounding tissues.
  4. X-ray exposure is performed for each required view (one or two views).
  5. Images are processed (digitally or film) and sent to a radiologist for interpretation and reporting.

Coding Guidelines

  • Code 73560 is designated for a unilateral examination of one knee. If both knees are imaged, it should be billed bilaterally, typically by coding 73560 with modifier 50 or by coding 73560 twice with appropriate laterality modifiers (RT and LT), depending on payer-specific guidelines.
  • This code is specifically for examinations comprising 1 or 2 views. If three views are obtained, use CPT code 73562 (X-ray, knee, 3 views). If four or more views are obtained, use CPT code 73564 (X-ray, knee, 4 or more views).
  • Documentation must clearly specify the clinical indication for the examination and the number of views performed.
  • Professional (26) and technical (TC) components may be billed separately depending on the billing entity and setting (e.g., hospital vs. physician office).
