Billing tips

Always append RT or LT modifier to specify laterality - this is a CMS requirement for all bilateral procedures and prevents automatic denials
Impact: Prevents 100% claim denial and resubmission delays averaging 30-45 days
Split bill with modifier 26 and TC when professional and technical components are performed by different entities to maximize appropriate reimbursement
Impact: Ensures both facilities receive correct payment allocation: $44.12 for professional component and $156.43 for technical component
Document the specific joint imaged (shoulder, elbow, or wrist) in both the order and the report - vague 'upper extremity' documentation often triggers medical necessity denials
Impact: Reduces denial rate by approximately 15-20% based on specificity requirements
Verify prior authorization before scheduling - most commercial payers require pre-auth for MRI studies and failure to obtain results in automatic denial
Impact: Prevents 100% payment denial on claims averaging $200-$600 depending on payer contract
When billing for same-day bilateral joint MRIs, bill 73221 with RT and 73221 with LT and modifier 59 on the second line to indicate distinct anatomical sites
Impact: Secures payment for second study which might otherwise be denied as duplicate, representing additional $200.55 in Medicare revenue
Ensure ordering physician documents failed conservative treatment or specific trauma/acute symptomatology to establish medical necessity for high-cost imaging
Impact: Reduces medical necessity denials by 25-30% and supports LCD/NCD compliance for Medicare claims

Frequently asked questions

What is the Medicare reimbursement rate for CPT 73221 in 2025?

The 2025 Medicare national average reimbursement rate for CPT 73221 is $200.55 for both facility and non-facility settings. This rate includes both the technical and professional components when billed globally. The work RVU is 1.35, PE RVU is 4.76, and MP RVU is 0.09, totaling 6.2 RVUs multiplied by the 2025 conversion factor of 32.3465.

Does CPT 73221 require prior authorization from Medicare or commercial payers?

Medicare does not typically require prior authorization for 73221, but medical necessity must be documented per Local Coverage Determinations (LCDs). Most commercial payers DO require prior authorization for MRI studies. Always verify authorization requirements with the specific payer before scheduling to avoid denials. Some Medicare Advantage plans also require pre-authorization despite traditional Medicare not requiring it.

What is the difference between CPT 73221 and 73222?

CPT 73221 is for MRI of an upper extremity joint WITHOUT contrast dye, while CPT 73222 is for the same study WITH intravenous contrast material. Code 73223 covers MRI performed both without contrast followed by with contrast and further sequences. The clinical indication and radiologist preference determine which code is appropriate. 73221 reimburses at $200.55 while contrast-enhanced studies have different reimbursement rates.

Can you bill CPT 73221 for both shoulders on the same day?

Yes, you can bill 73221 twice for bilateral shoulder MRIs performed on the same day. Bill the first shoulder with either RT or LT modifier, and the second with the opposite laterality modifier plus modifier 59 to indicate a distinct procedural service. Without modifier 59, the second claim will likely be denied as a duplicate. Each study should be separately medically necessary and documented.

What diagnosis codes support medical necessity for CPT 73221?

Common supporting ICD-10 codes include M75.100-M75.122 (rotator cuff tears), S43.4 (shoulder sprain), M19.01 (shoulder osteoarthritis), M25.51 (joint pain), M75.3 (shoulder bursitis), and M24.81 (other specific joint derangement). The diagnosis must correlate with the specific joint imaged and clinical documentation should support why MRI is necessary versus less expensive imaging modalities like X-ray or ultrasound.

How do you bill CPT 73221 when the technical and professional components are split?

When split billing, the facility performing the MRI scan bills 73221-TC (technical component only) for the equipment, technologist, and supplies, receiving approximately $156.43. The interpreting radiologist bills 73221-26 (professional component only) for the interpretation and report, receiving approximately $44.12. The sum of these split components equals the global fee. Never bill both the global code and split components, as this results in overpayment and audit risk.

What are the RVU values for CPT 73221 in 2025?

CPT 73221 has a total RVU of 6.2 for 2025, broken down as: Work RVU 1.35, Practice Expense (PE) RVU 4.76 (same for both facility and non-facility settings), and Malpractice (MP) RVU 0.09. These RVUs are multiplied by the 2025 conversion factor of 32.3465 to calculate the Medicare payment of $200.55. RVU values are established by CMS based on resource costs and physician work.
