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 sterile gauze pad used for wound care and medical dressings. The gauze is non-impregnated (meaning it doesn't contain medications or other substances), sterile to prevent infection, and measures between 16 and 48 square inches in size. It does not have an adhesive border, so it would typically need to be secured with tape or other means. This is a single-use dressing item.

Additional Information

This is a medical supply code for billing purposes. The actual gauze pad is a sterile wound dressing that comes individually packaged. Size specification helps ensure appropriate coverage for different wound sizes.
