What 93986 covers

Before hemodialysis access creation, duplex mapping surveys arterial inflow and venous outflow vessels in one extremity to help identify suitable anatomy. A vascular laboratory or imaging department typically performs the ultrasound, with a qualified practitioner interpreting the findings. This study evaluates vessels for access planning rather than an existing fistula or graft.

Select 93986 for a complete unilateral study and 93985 for a complete bilateral study. Documentation should identify the side and describe the vessels evaluated and relevant findings for access planning. The service has professional and technical components: modifier 26 identifies interpretation only, modifier TC identifies the technical service, and reporting without either modifier represents the global service. The cardiovascular diagnostic multiple procedure reduction applies to the technical component.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

What should the report document?

Document the side, vessels evaluated, and findings relevant to determining vessel suitability for hemodialysis access creation.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
