Billing tips

Bill 75774 for each additional vessel studied beyond the base angiography code. Count each selective catheterization and imaging separately.
Impact: Each correctly documented vessel adds $92.83 in Medicare reimbursement; a typical multi-vessel study may justify 3-5 units
Ensure the radiologist's report specifically identifies and describes findings for each individual artery to support multiple units of 75774.
Impact: Detailed documentation prevents audits and denials; missing vessel-specific descriptions can result in downcoding to single vessel rate, losing $92.83 per vessel
Link 75774 to the appropriate selective catheterization code (36245-36248 series) for the same vessel to demonstrate the imaging corresponds to selective positioning.
Impact: Proper code pairing prevents unbundling denials and supports medical necessity; mismatched codes trigger automatic payment denials
Use modifier 59 when billing multiple units of 75774 if payer edits bundle them together, but only when vessels are truly distinct and separately documented.
Impact: Appropriate modifier 59 use recovers $92.83 per vessel that would otherwise be denied; inappropriate use increases audit risk
For hospital billing, verify whether billing 75774 globally or split with modifier 26/TC based on employment arrangement and facility agreements.
Impact: Incorrect component billing causes payment delays or denials; coordination between facility and physician billing prevents duplicate claim denials
Do not bill 75774 for the primary vessel in a family of codes; this is an add-on code only for additional vessels beyond the base angiography procedure.

Frequently asked questions

What is the Medicare reimbursement rate for CPT code 75774 in 2025?

The 2025 Medicare national average reimbursement for CPT 75774 is $92.83 for both facility and non-facility settings. This rate is based on a total RVU of 2.87 multiplied by the 2025 conversion factor of 32.3465.

How many times can I bill CPT 75774 for a single procedure?

You can bill CPT 75774 once for each additional artery studied beyond the primary vessel. There is no absolute limit, but each unit must be supported by documentation showing selective catheterization and imaging of a distinct arterial territory with separate interpretation. Typical studies involve 2-4 additional vessels.

Is CPT 75774 an add-on code or can it be billed alone?

CPT 75774 is an add-on code and cannot be billed alone. It must be reported in conjunction with a primary angiography code from the vascular imaging family (such as 75625-75630, 75710-75716). The add-on code represents each additional vessel beyond the primary territory covered by the base code.

What is the difference between CPT 75774 and 75625?

CPT 75625 is a base code for angiography of a primary arterial territory (such as aorta and bilateral lower extremity runoff), while CPT 75774 is an add-on code for each additional individual artery studied beyond the primary territory. 75625 is billed once per study; 75774 is billed per additional vessel.

Do I need modifier 59 when billing multiple units of CPT 75774?

Modifier 59 may be required when payer edits bundle multiple units of 75774 together, but only use it when vessels are truly distinct and separately documented. Many payers recognize 75774 as a per-vessel code without requiring modifier 59 for multiple units, but some automated systems flag it. Check individual payer policies before routinely appending modifier 59.

What documentation is required to support billing CPT 75774?

Documentation must include specific anatomic identification of each artery studied, separate interpretation and findings for each vessel, evidence of selective catheterization for each vessel, and medical necessity for imaging each additional territory. The radiologist's report must clearly delineate findings for each individual artery to support each unit billed.

Can CPT 75774 be billed with both modifier 26 and TC?

CPT 75774 can be split into professional (modifier 26) and technical (modifier TC) components, but not by the same entity. In hospital settings, the facility typically bills the TC component for equipment and supplies, while the radiologist bills modifier 26 for interpretation. Solo practitioners in office settings bill the code globally without modifiers.
