Summary & Overview
CPT 75860: Supervision and Interpretation of Petrosal/Inferior Sagittal Venography
CPT code 75860 covers supervision and interpretation of petrosal and inferior sagittal catheter placement with imaging of the venous sinus or jugular vein following contrast administration. This specialized radiologic service is used to evaluate venous anatomy and pathology in settings where catheter-directed venography is required, often by interventional radiologists or neurointerventionalists. The code matters nationally because it represents a high-skill diagnostic procedure that informs management of complex cerebrovascular and cranial venous disorders.
Key payers in scope for national coverage and policy considerations include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find concise benchmarks and clinical context for the procedure, an outline of typical sites of service, and the policy and billing considerations that commonly affect reimbursement and documentation. The publication highlights common use cases for petrosal and inferior sagittal venography, coding clarity around supervision and interpretation services, and where data are not available in the input. The goal is to give clinicians, coders, and administrators a clear, national-level primer on what 75860 represents and the practical elements that influence billing and coverage decisions.

Clinical & Coding Specifications
Clinical Context
A patient presents with symptoms suggestive of cerebral venous hypertension and lateralizing endocrine dysfunction (such as Cushing disease) requiring evaluation for venous sampling. The interventional neuroradiology team performs selective catheterization of the bilateral inferior petrosal sinuses and potentially the contralateral inferior sagittal sinus or jugular veins. Under fluoroscopic guidance and after vascular access (commonly via the femoral vein), catheters are advanced to the petrosal and inferior sagittal venous structures. Contrast is injected for venous sinus or jugular imaging to confirm catheter position and to obtain pressure and blood samples for central to peripheral hormone gradients. The procedure is supervised and interpreted by the attending physician who documents catheter placement, contrast findings, any anatomic variants or complications, and provides interpretation of imaging and sampling results for endocrine correlation. Typical site of service is an interventional radiology suite, angiography suite, or hospital-based catheterization laboratory. Typical patient scenario: an adult with biochemical evidence of ACTH-dependent Cushing syndrome undergoing bilateral inferior petrosal sinus sampling with contrast venography to distinguish pituitary versus ectopic ACTH source prior to neurosurgical planning.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | Use when only the physician interpretation/supervision component is billed separately from technical services. |
50 | Bilateral procedure | Use when identical catheterization and imaging are performed bilaterally and payer requires bilateral modifier reporting. |
52 | Reduced services | Use when the procedure is partially reduced or not fully completed for documented clinical reasons. |
53 | Discontinued procedure (safe termination) | Use when the procedure is started but terminated due to patient condition or complication. |
59 | Distinct procedural service | Use when another unrelated procedure is performed in a separate vascular territory or session and needs separation from this service. |
62 | Two surgeons | Use when two surgeons work together as primary surgeons during complex access or management and payer requires this modifier. |
76 | Repeat procedure by same physician | Use when the same physician repeats the procedure later the same day for clinical reasons. |
77 | Repeat procedure by another physician | Use when a different physician repeats the procedure the same day (note: 77 not in provided list; excluded). |
78 | Unplanned return to the operating/procedure room by the same physician following initial procedure for a related procedure during the postoperative period | Use if patient requires an unplanned return for an access-related complication or repeat sampling under anesthesia. |
80 | Assistant surgeon present | Use when an assistant surgeon is present and payer accepts modifier for assisting during access or device management. |
81 | Minimum assistant surgeon | Use when a minimal assistant role is documented and payer recognizes this modifier. |
82 | Assistant not required — qualified resident not available | Use in teaching hospitals when an assistant is required but a qualified resident is unavailable. |
59 | Distinct procedural service | (Already listed) |
