Billing tips

Always bill 75840 separately from the catheterization code (36011-36012 for selective adrenal vein catheterization), as these are distinct services under NCCI rules
Impact: Ensures full reimbursement of $124.21 for imaging plus separate payment for catheterization ($150-300 depending on selectivity)
Document bilateral venography attempts even if one side is unsuccessful; use modifier 52 only if unilateral attempt was planned from the start
Impact: Preserves full $124.21 reimbursement versus 50% reduction with modifier 52
Bill separately for each adrenal venous sampling procedure (36500 or unlisted code) as this is the blood collection component, distinct from the venography imaging
Impact: Additional $50-200 reimbursement for sampling procedure depending on payer and code selection
Ensure radiologist's report specifically describes contrast injection, venous anatomy visualization, and any anatomic variants; generic fluoroscopy reports will be denied
Impact: Prevents denials requiring appeals that delay payment 60-90 days
For hospital outpatient settings, bill the global code without modifiers; facility bills separately for technical component automatically
Impact: Avoids 20-30% payment reduction from incorrect modifier 26 usage in wrong setting
Bundle contrast material supply costs into the technical component; do not separately bill contrast agents when performing in physician office
Impact: Prevents $50-100 denial for duplicate billing of included supplies

Frequently asked questions

What is the Medicare reimbursement rate for CPT 75840 in 2025?

The 2025 Medicare national average reimbursement for CPT 75840 is $124.21 for both facility and non-facility settings. This is based on 3.84 total RVUs multiplied by the 2025 conversion factor of 32.3465.

Can CPT 75840 be billed with adrenal venous sampling codes on the same day?

Yes, CPT 75840 (imaging/supervision) is separately reportable from adrenal venous sampling codes. The venography represents the radiologic supervision and interpretation, while sampling codes (typically 36500 or unlisted codes) represent the blood specimen collection. Both services can be billed when performed together with appropriate documentation.

What diagnosis codes support medical necessity for billing 75840?

Primary diagnosis codes include E26.09 (primary aldosteronism), E26.01 (Conn's syndrome), D35.00 (adrenal gland benign neoplasm), E27.5 (adrenomedullary hyperfunction), and I15.2 (hypertension secondary to endocrine disorders). Documentation should show failed medical management or biochemical evidence requiring anatomic localization.

Do I need modifier 26 when billing 75840 in a hospital setting?

Only use modifier 26 if you are the interpreting physician billing separately for professional services while the hospital bills the technical component. If you are billing globally or in a physician office setting, do not use modifier 26. Incorrect modifier use results in significant underpayment.

What is the difference between CPT 75840 and renal venography codes?

CPT 75840 specifically covers adrenal vein venography with selective catheterization of the adrenal veins themselves. Renal venography codes (75831) cover only the renal veins. While anatomically close, these are distinct procedures requiring separate selective catheterization and are separately billable when both are performed.

How many RVUs is CPT 75840 worth in 2025?

CPT 75840 has 3.84 total RVUs in 2025, consisting of 1.14 work RVUs, 2.63 practice expense RVUs (both facility and non-facility), and 0.07 malpractice RVUs according to the CMS Physician Fee Schedule.

What documentation is required to avoid denials for CPT 75840?

Required documentation includes: formal radiologist interpretation report describing adrenal vein catheterization and contrast visualization, fluoroscopic images showing selective positioning, medical necessity justification (lab values showing hyperaldosteronism), contrast administration records, and correlation with clinical indication. Generic procedure notes without specific adrenal vein findings will be denied.
