What 73560 covers

This study captures one or two distinct radiographic views of a single knee, most often an anteroposterior and a lateral projection. Orthopedic surgeons, primary care physicians, urgent care clinicians, and emergency clinicians order it to look for fractures, effusion, joint space narrowing, osteophytes, loose bodies, or hardware position after surgery. A radiologic technologist acquires the images in an office, imaging center, or hospital, and a radiologist or the treating physician interprets them and documents a written report.

Code selection depends on the number of views of one knee. One or two views fall here, while three views or four or more views move to the higher codes. The report should state the views obtained, findings, and impression. The service splits into a professional component (modifier 26, interpretation) and a technical component (modifier TC, equipment and staff); billing without a modifier claims the global service, which is typical when an office owns the equipment and reads its own films. When both knees receive separate unilateral examinations, report each knee with RT or LT. CMS pays each side separately at 100%.

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.

73560 billing questions

When should a knee film be reported with this code instead of the three-view or four-view codes?

Count the distinct projections of the same knee documented in the report. One or two views, such as AP and lateral, belong here; three views go to 73562 and four or more views to 73564.

How are separate films of both knees reported?

Report the unilateral examination separately for each knee, identified with RT and LT. CMS pays each side at 100%.

Is a single standing AP view of both knees on one image reported with this code?

No. A bilateral standing anteroposterior view capturing both knees together is reported with 73565. Do not automatically bill 73560 for additional views taken during the same knee examination.

When is modifier 26 or TC appended?

Append 26 when the physician only interprets the images, such as a radiologist reading hospital films, and TC when the entity only supplies equipment and technologist. An office that both takes and reads the films bills the global service without a modifier.

Can the ordering physician bill an interpretation if a radiologist also reads the film?

Medicare generally pays one interpretation per study, the one that contributes to the patient's diagnosis and is documented in a formal report. A brief review noted in an E/M note does not support a separate 26 claim.

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.
