Final answer:
The practice of assigning separate codes for component services instead of a combination code is known as unbundling. It allows for more precise billing for each individual service, but correct coding guidelines must be followed to ensure compliance.
Step-by-step explanation:
Assigning separate codes for component services instead of a combination code is called unbundling. Unbundling is the practice of breaking down the procedures or services that are typically included in a single comprehensive code into their separate parts.
Each component is then assigned its individual code. This is often done for billing and insurance purposes, where the combined procedure may not cover all individual services performed or required. When undertaken appropriately, unbundling can facilitate a more precise billing process. However, it is important to follow correct coding guidelines to avoid any issues of noncompliance.
