Vascular ultrasound
About 93985: Bilateral hemodialysis access vessel mapping
Bilateral duplex mapping evaluates arterial inflow and venous pathways to help plan hemodialysis access creation in a patient needing vascular access.
This duplex ultrasound maps vessels relevant to hemodialysis access on both sides, assessing arterial inflow and the veins and access-related anatomy needed for planning. A vascular sonographer typically acquires the images in a vascular laboratory or imaging department; a qualified physician, such as a radiologist or vascular specialist, interprets the study. It is commonly performed before choosing a site for a dialysis fistula or graft.
Report 93985 for a complete bilateral mapping examination, supported by documentation of the clinical need and the vessels and sides examined. The code is already priced as bilateral, so modifier 50 does not increase payment. The global service is billed without a component modifier; modifier 26 identifies the interpretation, and modifier TC identifies the technical service. When multiple cardiovascular diagnostic procedures are performed, the multiple procedure reduction applies to the technical component.

93985 billing questions
When should 93985 be selected instead of 93986?
Use 93985 for a complete bilateral hemodialysis-access mapping study. Use 93986 when the complete study is unilateral.
Does 93985 include both arms?
Yes. The code is priced as bilateral, and modifier 50 does not increase payment.
Can the professional and technical services be billed separately?
Yes. Modifier 26 identifies the physician interpretation, and modifier TC identifies the equipment and staff service. Without either modifier, the claim represents the global service.
Does the multiple procedure reduction affect the entire service?
For multiple cardiovascular diagnostic procedures, the reduction applies to the technical component of 93985.
How is 93985 different from 93990?
93985 maps vessels for hemodialysis access planning. Code 93990 evaluates an existing hemodialysis access rather than providing the complete bilateral planning study.
What documentation supports reporting 93985?
Document the access-planning indication, bilateral examination, and the vessels assessed. The record should support that the study was a complete mapping examination.
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.
