About 75809: Nonvascular shunt patency imaging
Fluoroscopic shunt imaging evaluates flow or patency in a nonvascular shunt, such as a cerebrospinal fluid shunt, when obstruction or leakage is suspected.
A nonvascular shuntogram uses fluoroscopic imaging to follow contrast through a shunt and assess its passage, patency, or possible leak. A common clinical setting is evaluation of a cerebrospinal fluid shunt, such as a ventriculoperitoneal shunt, when symptoms raise concern for malfunction. The study may involve contrast introduced through the shunt access reservoir, with a radiologist supervising the imaging and interpreting the findings. It is performed in a radiology department or hospital imaging setting equipped for fluoroscopy.
Report this code for the radiologic shunt study, not for shunt placement, revision, or repair. Documentation should identify the nonvascular shunt examined, the imaging performed, and the contrast-flow findings and interpretation. Modifier 26 represents the professional interpretation; modifier TC represents the technical service, including equipment and staff. Without either modifier, the code represents the global service. CMS applies the cardiovascular diagnostic multiple procedure reduction to the technical component; when that reduction is triggered, it affects the technical portion rather than the professional interpretation.

- Professional and technical components
- Diagnostic test with a professional component (modifier 26, interpretation) and a technical component (modifier TC, equipment and staff); billing without a modifier is the global service.

How this local rate is calculated
Each RVU component is multiplied by its own geographic practice cost index (GPCI). The three adjusted components are added, then multiplied by the conversion factor. These are the inputs used for 75809 in Arizona.

75809 billing questions
When is a shuntogram appropriate instead of plain shunt-series radiographs?
Use this code for fluoroscopic evaluation of contrast passage through a nonvascular shunt. Plain shunt-series films show catheter course and continuity but do not trace contrast flow through the shunt.
Which modifier identifies the radiologist's interpretation?
Append modifier 26 for the professional interpretation. Modifier TC identifies the technical service, and no modifier represents the global service.
Does this code include shunt revision or repair?
No. It represents radiologic supervision and interpretation of the shunt study, not surgical treatment of a malfunctioning shunt.
What documentation supports reporting a nonvascular shuntogram?
Document the shunt evaluated, the fluoroscopic study and contrast-flow observations, and the radiologist's findings, including any evidence of impaired passage or leakage.
Which portion is affected by the cardiovascular diagnostic multiple procedure reduction?
CMS applies the reduction to the technical component. The professional interpretation is represented separately with modifier 26.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
