Radiology
About 73580: Knee joint contrast radiographic examination
Reports radiographic imaging and interpretation of a contrast study of the knee joint, typically performed after contrast is introduced into the joint.
This service covers radiographic imaging and interpretation of a knee arthrogram: contrast is introduced into the joint, and images are obtained to assess its internal structures. A radiologist typically interprets the study; imaging staff acquire the images, and a physician may perform the joint injection. It is distinct from routine knee x-rays without intra-articular contrast and from an MRI arthrogram.
Report 73580 for the radiographic arthrogram service, supported by documentation identifying the knee, the contrast study, the images obtained, and the interpretation. The contrast injection is commonly reported separately with 27370. CMS prices the professional interpretation with modifier 26 and the equipment-and-staff service with modifier TC; billing without either modifier represents the global service. When both knees are examined, CMS pays each side separately at 100%.

73580 billing questions
How does 73580 differ from routine knee x-rays?
73580 is for radiographic imaging and interpretation of a knee arthrogram using contrast introduced into the joint. Routine knee x-ray codes describe noncontrast examinations and are selected by the number of views.
Is the contrast injection included in 73580?
The injection is commonly reported separately with 27370. Keep documentation clear about the injection and the radiographic arthrogram service.
When should modifier 26 or TC be used?
Use modifier 26 for the professional interpretation and modifier TC for the technical service, including equipment and staff. Without either modifier, 73580 represents the global service.
How is bilateral knee arthrography paid?
CMS pays each side separately at 100% when both knees are examined. Document which knee was studied and report the services for each side.
What documentation supports 73580?
The record should identify the knee, document that the examination used intra-articular contrast, and support the radiographic imaging and interpretation. The report should reflect the arthrogram findings.
