CPT Code 73221: MRI, Any Joint of Upper Extremity, Without Contrast

CPT Code 73221 may be billed as a repeat clinical diagnostic laboratory test when it is medically necessary to reassess the same upper extremity joint due to new symptoms, progression of a condition, or lack of improvement. Documentation must clearly support medical necessity and indicate that the provider is evaluating changes since the original procedure or service.

Providers must ensure accurate documentation, correct use of modifiers (such as -RT or -LT), and clear justification for medical necessity. Refer to your Medicare Administrative Contractor (MAC) for any specific local coverage determinations related to this clinical diagnostic laboratory test.

Magnetic Resonance Imaging (MRI) CPT codes for the upper extremity include the following: 73222, which refers to an MRI of any joint in the upper extremity performed with contrast material; 73223, which describes an MRI performed initially without contrast, followed by contrast material and additional imaging sequences; and 73225, which covers an MRI performed with or without contrast material of any upper extremity joint.
