What 73221 covers
This service uses magnetic resonance imaging to evaluate an upper-extremity joint without contrast material. Common targets include the shoulder, elbow, and wrist; clinicians may request the study for suspected rotator cuff or labral injury, internal joint derangement, or unexplained joint pain. An imaging technologist acquires the images, and a radiologist or other qualified physician interprets them in an outpatient imaging center or hospital department.
Select this code when the study is directed at a joint rather than a nonjoint region of the arm, and when contrast is not used. The order and report should identify the joint and clinical reason for imaging, and the record should support the performed protocol. The global service includes the technical work and interpretation; modifier 26 reports interpretation only, and modifier TC reports the technical portion only. CMS applies the diagnostic imaging multiple procedure reduction to both components. For bilateral imaging, each side is paid separately at 100%.

How to choose
- 73218Extremity MRINon-joint, without contrast
- This code is for MRI focused on a joint. Code 73218 applies when the target is an upper-extremity region rather than a joint.
- 73222Joint MRIUpper extremity, with contrast
- Both describe MRI of an upper-extremity joint, but 73222 is used when contrast is administered.
- 73223Joint MRIWithout and with contrast
- Use 73223 for joint imaging performed both without and with contrast; use this code for imaging without contrast.
73221 billing questions
How does this differ from MRI of the upper extremity?
Use this code when imaging is directed at an upper-extremity joint, such as the shoulder, elbow, or wrist. Code 73218 describes MRI of an upper-extremity area rather than a joint.
When should contrast MRI codes be used instead?
Use 73222 when contrast is used, or 73223 when the study is performed both without and with contrast. This code is for a study performed without contrast.
Can the professional and technical portions be billed separately?
Yes. Modifier 26 identifies the interpretation, while modifier TC identifies the equipment and staff portion; billing without either modifier represents the global service.
How is bilateral joint imaging reported?
Report each side distinctly when both upper-extremity joints are imaged. CMS pays each side separately at 100%.
What happens when multiple imaging procedures are performed?
CMS's diagnostic imaging multiple procedure reduction applies to both the technical and professional components. The reduction can therefore affect either a global claim or separately billed components.
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.
