CPT 70553Radiology

Mri brain stem w/o & w/dye

CPT 70553 covers an MRI scan of the brain stem performed twice—once without contrast dye, then again after injecting contrast dye to highlight blood vessels and abnormalities. This dual-sequence imaging provides comprehensive views to diagnose conditions like tumors, strokes, or multiple sclerosis.

Billing tips

Verify authorization specifically for 'with and without contrast' protocol before scheduling—many payers require pre-authorization for contrast studies and will deny if only non-contrast was approved
Impact: Prevents 100% denial ($314.08 loss) and patient balance billing issues; pre-auth compliance reduces denial rate by 40-60%
Document medical necessity for both non-contrast and contrast phases in the ordering physician's notes and radiologist's interpretation—payers frequently deny when clinical indication doesn't support dual protocol
Impact: Reduces denial rate by 35%; appeals with enhanced documentation succeed 70% of time but cost $25-50 in administrative overhead per appeal
Do not bill 70553 if only contrast or only non-contrast images were obtained—use 70551 (without contrast) or 70552 (with contrast) instead to avoid upcoding allegations
Impact: Prevents fraud allegations and recoupment actions; incorrect coding can trigger RAC audits with potential penalties of 3x the overpayment amount
Ensure contrast administration and type of contrast agent are documented in the technical note—missing contrast documentation is a top audit trigger for dual-sequence studies
Impact: Reduces audit risk by 45%; audits without contrast documentation result in downcoding to 70551 with $100-150 recoupment per case
Bill globally (no modifier) when facility owns equipment and employs radiologist; split with 26/TC modifiers when professional and technical components are provided by different entities
Impact: Proper modifier use ensures accurate payment distribution; incorrect global billing when split is required can cause 100% denial from one payer

Frequently asked questions

What is the difference between CPT 70551, 70552, and 70553?

CPT 70551 is MRI brain without contrast, 70552 is MRI brain with contrast only, and 70553 is MRI brain performed both without and with contrast (dual protocol). Code 70553 requires both sequences to be performed and documented. The 2025 Medicare payment for 70553 is $314.08, which is higher than either single-sequence code because it represents more technical work and imaging time.

How much does Medicare pay for CPT code 70553 in 2025?

Medicare pays $314.08 for CPT 70553 in 2025 based on the national average non-facility rate. The code has 9.71 total RVUs (2.29 work RVU, 7.26 practice expense RVU, 0.16 malpractice RVU) multiplied by the 2025 conversion factor of 32.3465. Actual payment may vary by locality based on geographic practice cost indices.

Does CPT 70553 require prior authorization from insurance?

Most commercial payers and Medicare Advantage plans require prior authorization for CPT 70553 due to its advanced imaging status and contrast use. Traditional Medicare does not require prior authorization but does require medical necessity. Always verify authorization requirements with the specific payer before scheduling, as denial rates exceed 40% when authorization policies are not followed.

Can you bill 70553 and 70551 together for the same brain MRI?

No, you cannot bill both codes together. CPT 70553 is a comprehensive code that includes both the non-contrast sequences (70551) and contrast sequences (70552). Billing both would be considered unbundling and duplicate billing. Use only 70553 when both protocols are performed, or use 70551 or 70552 individually if only one sequence is obtained.

What diagnosis codes support medical necessity for CPT 70553?

Diagnoses supporting 70553 include suspected or known brain tumors, multiple sclerosis, acoustic neuroma, brainstem lesions, stroke evaluation, vascular malformations, unexplained cranial nerve deficits, and demyelinating diseases. Simple headache or dizziness without neurological findings typically do not support the dual-contrast protocol. Check your local Medicare LCD for specific coverage criteria, as policies vary by contractor.

What modifier should I use when billing only the professional component of 70553?

Use modifier 26 when billing only the professional component (radiologist interpretation) of CPT 70553. This applies when the facility owns the MRI equipment and bills the technical component separately with modifier TC. The professional component represents approximately 30-40% of the total allowable payment, while the technical component represents 60-70%.

How do you appeal a denial for CPT 70553 due to lack of medical necessity?

Submit a written appeal with: (1) complete clinical documentation showing specific symptoms requiring contrast imaging, (2) ordering physician notes explaining why dual protocol was necessary, (3) radiologist interpretation highlighting findings requiring contrast, (4) peer-reviewed literature supporting contrast use for the specific indication, and (5) request for peer-to-peer review. Include any relevant prior imaging showing progression. Appeal within payer timelines (typically 30-180 days) and reference specific LCD criteria if applicable.
