Healthcare Common Procedure Coding System

Last updated: 3/24/2026

What is a HCPCS Code?

HCPCS (Healthcare Common Procedure Coding System) codes are used to identify medical procedures, supplies, and services for billing purposes. These codes help standardize how healthcare services are reported and billed across different providers and insurance companies.

Detailed Description

This code represents ambulance transportation with basic life support (BLS) level care during an emergency situation. Basic life support includes essential medical care such as oxygen administration, basic airway management, bleeding control, and monitoring of vital signs. This is used when you need emergency ambulance transport but don't require the advanced medical interventions that would be provided by paramedics (such as IV medications or advanced cardiac procedures).

Additional Information

This code specifically covers emergency transport with basic life support. The actual cost may vary significantly based on distance traveled, geographic location, and specific ambulance service provider. Insurance coverage varies by plan and may require prior authorization in non-emergency situations.
