What 73565 covers
This study obtains a weight-bearing frontal image of both knees, allowing comparison of alignment and joint-space appearance under load. It is commonly ordered when evaluating knee osteoarthritis or other conditions in which standing alignment or joint-space narrowing matters. A radiologic technologist positions the patient for the image; a radiologist or other qualified physician interprets it. The service is performed in imaging departments, hospitals, and outpatient imaging settings.
Report the code for the bilateral standing AP study, rather than selecting a unilateral knee code based only on the number of images. The order and imaging record should support bilateral imaging in the standing position, and the interpretation should document the findings. The code is already priced as bilateral, so modifier 50 does not increase payment. The professional interpretation may be billed with modifier 26, the equipment and staff portion with modifier TC, or the global service without a modifier.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

73565 billing questions
When should this code be chosen instead of a unilateral knee X-ray code?
Use this code for the bilateral standing AP knee study. Codes 73560, 73562, and 73564 describe unilateral knee examinations selected by the number of views.
Should modifier 50 be appended for imaging both knees?
The code is already priced as bilateral, and modifier 50 does not increase payment.
How are the professional and technical services billed?
Use modifier 26 for the interpretation and modifier TC for the equipment and staff portion. Billing without either modifier represents the global service.
What documentation supports reporting this code?
The order and imaging record should show that both knees were imaged in the standing position. The interpretation should describe the findings from the bilateral study.
Can this code be reported for a three-view knee examination?
No. This code describes a bilateral standing AP study; a unilateral three-view knee examination is reported with 73562.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
