What 93799 covers
CPT 93799 is used for cardiovascular work that does not fit a more specific CPT service or procedure code. It is distinct from named services such as bioimpedance cardiovascular analysis (93701), extracellular-fluid analysis by bioimpedance spectroscopy (93702), venous-pressure determination (93770), and ambulatory blood pressure monitoring (93784). Those codes identify their own services rather than serving as general unlisted cardiovascular choices. Use 93799 when a specific cardiovascular code does not describe the work performed.
Medicare assigns status C: CMS publishes no national payment amount, and the Medicare Administrative Contractor sets payment for each claim. For a diagnostic test with professional and technical components, modifier 26 identifies the interpretation and modifier TC identifies the equipment and staff. When billed without a modifier, the service is the global service.

How to choose
- 93701Bioimpedance analysisCardiovascular assessment
- 93701 identifies bioimpedance cardiovascular analysis. Choose 93799 only when the cardiovascular service is not accurately described by that specific code or another named code.
- 93702Bioimpedance testExtracellular fluid analysis
- 93702 identifies bioimpedance spectroscopy for extracellular-fluid analysis. It is more specific than 93799 when that is the service performed.
- 93770Venous pressurePressure determination
- 93770 identifies determination of venous pressure. Use 93799 for a different cardiovascular service that has no specific code.
- 93784Blood pressure monitoringComplete service
- 93784 identifies ambulatory blood pressure monitoring. Do not use 93799 when the service performed is the monitoring described by 93784.
93799 billing questions
When should I use 93799 instead of a named cardiovascular code?
Use 93799 when no specific CPT code describes the cardiovascular service or procedure performed. If a named code describes the work, report that code instead.
How do modifiers 26 and TC apply?
For a diagnostic test with professional and technical components, modifier 26 identifies the interpretation and modifier TC identifies the equipment and staff. Billing without a modifier represents the global service.

It has physician fee schedule status C: CMS publishes no national payment amount, and the Medicare Administrative Contractor sets payment for each claim.
How does 93799 differ from 93784?
93784 identifies ambulatory blood pressure monitoring. Use 93799 for cardiovascular work that is not described by that or another specific CPT code.
