Billing tips

Verify that imaging includes both the abdominal aorta AND bilateral lower extremity runoff to the ankle level; incomplete studies should use modifier 52 or alternative codes
Impact: Prevents $50-75 downcoding to single-level angiography codes (75710, 75716) or automatic denials
Document separately billable catheter placement (36245-36248) when selective catheterization beyond the aorta is performed, as 75630 is a supervision and interpretation code only
Impact: Additional $150-400 reimbursement for catheter placement codes that are appropriately unbundled
Bill global code without modifiers in non-facility settings where you own equipment; split with 26/TC modifiers in hospital settings to capture appropriate component
Impact: Ensures full $151.38 reimbursement in appropriate settings versus underpayment from incorrect modifier use
Ensure contrast administration, number of images, vessels visualized, and clinical indication are explicitly documented in the radiology report for LCD compliance
Impact: Reduces audit risk and denial rate by approximately 30-40% based on common LCD requirements
Check for bundling with interventional codes (37220-37235) performed same session; angiography is typically included in intervention reimbursement unless distinct diagnostic study
Impact: Prevents $151.38 recoupment during post-payment audits for bundled services
Verify medical necessity with ankle-brachial index, duplex ultrasound, or CTA findings documented prior to invasive angiography to satisfy step-therapy requirements
Prevents medical necessity denials that affect 100% of reimbursement ($151.38 loss per claim)

Frequently asked questions

What is the Medicare reimbursement rate for CPT 75630 in 2025?

The 2025 Medicare national average reimbursement for CPT 75630 is $151.38 for both facility and non-facility settings. This is based on 4.68 total RVUs (2.0 work RVU, 2.45 PE RVU, 0.23 MP RVU) multiplied by the 2025 conversion factor of 32.3465.

Can CPT 75630 be billed with angioplasty codes on the same day?

Generally, CPT 75630 is bundled into angioplasty codes (37220-37235) when performed during the same session, as diagnostic angiography is considered part of the interventional procedure. It can only be billed separately with modifier 59 if a distinct diagnostic study with separate decision-making was performed prior to the decision to intervene, or if additional vascular territories beyond the intervention site were evaluated.

What is the difference between CPT 75630 and 75625?

CPT 75630 includes imaging of the abdominal aorta AND bilateral lower extremity runoff to the ankles, while CPT 75625 covers abdominal aortography only without lower extremity imaging. Code selection depends on the extent of vascular territories actually imaged during the procedure.

Do I need prior authorization for CPT 75630?

Prior authorization requirements vary by payer and region. Most Medicare Administrative Contractors do not require prior auth but do require medical necessity documentation. Commercial payers increasingly require prior authorization for invasive vascular imaging, and many mandate documentation of failed non-invasive testing (duplex ultrasound, CTA) before approving invasive angiography.

How many RVUs is CPT code 75630 worth?

CPT 75630 has a total of 4.68 RVUs for 2025, consisting of 2.0 work RVUs, 2.45 practice expense RVUs (both facility and non-facility), and 0.23 malpractice RVUs according to the CMS Physician Fee Schedule.

Should I use modifier 26 or TC for hospital-based angiography?

In hospital settings where the facility owns the equipment, physicians should bill CPT 75630 with modifier 26 for professional interpretation only, while the hospital bills with modifier TC for the technical component (equipment, staff, supplies). If you own the equipment in an office or independent imaging center, bill the global code without modifiers.

What diagnosis codes support medical necessity for CPT 75630?

Common supporting ICD-10 codes include I70.xx series (atherosclerosis of aorta and extremities), I73.9 (peripheral vascular disease), I77.1 (aortic stenosis), I71.xx (aortic aneurysm), L97.xx (non-pressure chronic ulcer of lower limb), and R02 (gangrene). Documentation should demonstrate that symptoms or clinical findings warrant invasive imaging beyond non-invasive testing.
