Billing tips

Always bill the catheterization procedure code (36251-36254) in addition to 75733, as the imaging code covers only radiological supervision and interpretation, not the catheterization itself
Impact: Additional $300-$800 reimbursement depending on catheterization complexity and vessel selection order
Document whether unilateral or bilateral adrenal artery imaging was performed; use modifier 50 or RT/LT appropriately to maximize compliant reimbursement for bilateral studies
Impact: Bilateral studies may yield up to 150% reimbursement ($251.33 vs $167.55) with proper documentation
Verify that the operative report clearly states 'adrenal artery' rather than just 'renal artery' or 'abdominal aortography' to support medical necessity for the specific code
Impact: Prevents downcoding to less specific codes like 75625 (abdominal aortography) which may have different reimbursement
Code 75733 is typically facility-based; ensure proper place of service coding (hospital outpatient 22 or inpatient 21) as this affects overall claim processing
Impact: No differential between facility and non-facility rates ($167.55 both), but incorrect POS codes trigger denials
When performed with adrenal vein sampling (36010), ensure separate documentation of diagnostic angiography versus venography to support billing both arterial and venous imaging codes
Impact: Prevents bundling denials; supports additional reimbursement for comprehensive adrenal vascular evaluation
Link appropriate ICD-10 codes for adrenal pathology (D35.0, E27.5, E26.0) to establish medical necessity; insufficient diagnosis coding is a primary denial reason

Frequently asked questions

What is the Medicare reimbursement rate for CPT code 75733 in 2025?

The 2025 Medicare national average reimbursement rate for CPT 75733 is $167.55 for both facility and non-facility settings, based on 5.18 total RVUs and the 2025 conversion factor of 32.3465.

Does CPT 75733 include the catheterization procedure or just the imaging?

CPT 75733 includes only the radiological supervision and interpretation (imaging component) of adrenal artery angiography. The catheterization procedure must be billed separately using appropriate catheter placement codes (typically 36251-36254 depending on vessel selection order).

Can CPT 75733 be billed bilaterally, and if so, what modifier should be used?

Yes, CPT 75733 can be billed bilaterally when both right and left adrenal arteries are imaged. Use modifier 50 for bilateral procedures or modifiers RT and LT on separate line items, depending on payer preference. Documentation must clearly support imaging of both adrenal arteries.

What diagnosis codes support medical necessity for CPT 75733?

Common supporting diagnoses include D35.0 (benign adrenal gland neoplasm), E26.0 (primary hyperaldosteronism), E27.5 (adrenomedullary hyperfunction including pheochromocytoma), and E24.0 (pituitary-dependent Cushing's disease). Documentation should link biochemical abnormalities to the need for selective angiography.

What is the difference between CPT 75733 and 75625 for adrenal imaging?

CPT 75733 represents selective adrenal artery angiography with specific catheterization of the adrenal arteries, while 75625 is for abdominal aortography that may incidentally show adrenal blood supply. Code 75733 requires selective catheter placement and provides superior adrenal arterial detail for lesion localization.

Is prior authorization required for CPT 75733 procedures?

Prior authorization requirements vary by payer and state. Many Medicare Advantage plans and commercial insurers require pre-authorization for interventional radiology procedures including selective adrenal angiography, as it is considered an advanced diagnostic study. Always verify with the specific payer before scheduling.

How many RVUs is CPT 75733 worth in 2025?

CPT 75733 has a total of 5.18 RVUs in 2025, consisting of 1.31 work RVUs, 3.79 practice expense RVUs, and 0.08 malpractice RVUs. The facility and non-facility PE RVU values are identical at 3.79.
