Healthcare Common Procedure Coding System

Last updated: 11/28/2025

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 a billing unit for an injection containing octafluoropropane microspheres, which are tiny gas-filled bubbles used as a contrast agent. The medication is measured and billed per milliliter (ml) administered. Octafluoropropane microspheres are specialized contrast agents that help healthcare providers see internal structures more clearly during certain medical imaging procedures.

Additional Information

This is a billing code for the contrast agent itself, measured per milliliter used. The actual medical procedure using this contrast agent would be billed separately with different codes.
