DVP Modifier in Medical Billing
The DVP modifier does not exist as a standard billing modifier in medical coding; the term "DVP" in the provided evidence refers to "Dynamic Venous Pressure" in hemodialysis access monitoring, not a billing modifier. 1
Clarification of Medical Billing Modifiers
The confusion likely stems from terminology overlap. In medical billing, the relevant modifiers for distinct or specialized services include:
Telemedicine Modifiers
- Modifier 95: Used to indicate services provided via interactive audio and video telecommunications systems for real-time telemedicine encounters 1
- Modifier GT: Alternative telemedicine modifier indicating "via interactive audio and video telecommunications systems" 1
- Modifier GQ: Specifically for asynchronous telecommunications in Federal telemedicine demonstration programs in Alaska or Hawaii 1
Key Billing Requirements
- Claims must include the appropriate CPT or HCPCS code along with the telemedicine modifier to certify that services were provided remotely 1
- The modifier certifies that the beneficiary was present at an eligible originating site when telemedicine services were furnished 1
- Proper coding with appropriate modifiers ensures accurate reimbursement when medical necessity is established 2
DVP in Clinical Context (Not Billing)
In the hemodialysis literature, DVP refers to:
- Dynamic Venous Pressure: Also called venous drip chamber pressure, measured in venous tubing during dialysis 1
- Used for surveillance of vascular access dysfunction, though studies question its utility in detecting stenoses in fistulae 1
This clinical measurement term should not be confused with billing modifiers, as they serve entirely different purposes in healthcare documentation.
