Billing tips

Always verify if the facility or physician is billing for the complete service versus separated professional/technical components using modifiers 26/TC
Impact: Prevents duplicate billing denials and ensures correct payment split; improper splitting can result in 100% claim rejection
Document the specific spinal arterial territory imaged (cervical, thoracic, lumbar) and medical necessity for selective catheterization in the operative report
Impact: Strengthens medical necessity justification and reduces audit risk; missing territory documentation causes 30-40% of denials
Do not bill 75705 with catheterization codes (36215-36218) separately unless performed in different vascular territories; bundling rules apply
Impact: Catheter placement is typically bundled; unbundling can trigger recoupment of $150-300 in improper payments plus penalties
Confirm pre-authorization for non-emergent spinal angiography as many payers classify this as a high-cost advanced imaging requiring prior approval
Impact: Lack of pre-auth results in automatic denial of the full $249.07 payment; appeals have low success rate without retrospective authorization
Use modifier 59 judiciously when billing multiple angiographic studies; ensure separate vascular territories are documented to justify distinct procedures
Impact: Appropriate modifier 59 use secures additional $200+ in reimbursement; inappropriate use flags claims for audit and potential fraud investigation
Bill on the same claim as any associated interventional procedures (embolization, stenting) performed during the same session to demonstrate complete procedural context

Frequently asked questions

What is the Medicare reimbursement rate for CPT 75705 in 2025?

The 2025 Medicare national average reimbursement for CPT 75705 is $249.07 for both facility and non-facility settings. This is based on 7.7 total RVUs (2.18 work RVU, 5.02 PE RVU, 0.5 MP RVU) multiplied by the 2025 conversion factor of 32.3465.

Does CPT 75705 include the catheterization procedure or just the imaging?

CPT 75705 is for radiological supervision and interpretation only. The catheterization procedure is typically reported separately using codes from the 36000-36299 series, though bundling rules often apply when performed during the same session. Check CCI edits to determine if separate payment is allowed.

When should I use modifier 26 versus modifier TC with CPT 75705?

Use modifier 26 when billing only the professional component (physician interpretation) if you do not own the equipment. Use modifier TC when billing only the technical component (equipment, supplies, staff) without the interpretation. In most hospital settings, the facility bills TC and the radiologist bills 26 separately.

What is the difference between CPT 75705 and 75716?

CPT 75705 is for angiography of the spinal arteries, while 75716 is for angiography of the vertebral arteries. Though anatomically related, these codes represent different vascular territories: 75705 focuses on arteries supplying the spinal cord itself, while 75716 examines the vertebral arteries in the neck before they reach the spinal cord.

Do I need prior authorization for CPT 75705?

Most commercial payers and Medicare Advantage plans require prior authorization for CPT 75705 as it is an invasive, high-cost diagnostic procedure. Traditional Medicare does not require prior authorization but does scrutinize medical necessity. Always verify specific payer requirements before scheduling non-emergent cases.

Can CPT 75705 be billed bilaterally or with modifier 50?

No, CPT 75705 is not typically billed with modifier 50 (bilateral) because spinal angiography inherently includes visualization of bilateral arterial supply as part of the complete diagnostic study. The code descriptor encompasses comprehensive spinal arterial imaging regardless of laterality.

What diagnosis codes support medical necessity for CPT 75705?

Common supporting diagnoses include spinal arteriovenous malformation (Q28.2), spinal cord ischemia (G95.11), myelopathy NOS (G95.9), spinal neoplasm (C72.0, D32.1), and vascular myelopathies (G95.19). Pre-operative vascular mapping diagnoses also support medical necessity. Documentation must clearly link the diagnostic imaging to the clinical condition requiring arterial visualization.
