What 73564 covers

This study obtains four or more distinct radiographic views of one knee. A series may combine AP and lateral views with oblique, tangential patellar, tunnel, or standing weight-bearing views. Orthopedic, sports medicine, and primary care clinicians order these images to evaluate osteoarthritis, fractures, patellar alignment, or knee replacement position. Technologists acquire the images in physician offices, imaging centers, and hospital outpatient departments; a radiologist or treating physician interprets them.

Select the code by counting distinct views obtained of each knee. The imaging record should identify the views or their number; a label such as “complete knee” alone does not establish the count. One or two views are reported with 73560, and three with 73562. Modifier 26 identifies the separately billed interpretation and report, while modifier TC identifies the separately billed imaging equipment, staff, and supplies. Billing without either modifier represents the global service. When four or more views are obtained of both knees, count and report each knee separately; CMS pays each side at 100% when performed bilaterally.

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.

73564 billing questions

How are views counted to choose this code over 73562?

Count distinct projections of the same knee documented in the imaging record. Three views support 73562, and four or more support 73564; repeat images of the same projection do not add a view.

How is this reported when both knees get four or more views?

Document the view count for each knee and report the bilateral service with side-specific claim information. CMS pays each side separately at 100%.

When should modifier 26 or TC be appended?

Use 26 for a separately billed interpretation and report, such as a physician reading images acquired by a hospital outpatient department. Use TC for separately billed image acquisition; bill globally when the billing entity furnishes both components.

Is a bilateral standing AP view the same as this code?

No. Code 73565 describes standing AP imaging of both knees. Code 73564 requires at least four distinct views of each knee reported.

Can a treating orthopedist bill the interpretation?

Yes, if the orthopedist interprets the knee images and documents a report. Modifier 26 identifies that professional component when another entity furnishes the imaging.

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.
