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 the collection of a specimen (such as a nasal swab, throat swab, saliva sample, or other body fluid) that will be used to test for SARS-CoV-2, the virus that causes COVID-19. This code covers the actual process of collecting the sample, regardless of what type of specimen is collected or where it's collected from on the body.

Additional Information

This code only covers the specimen collection process itself, not the actual laboratory testing or analysis of the sample. The type of specimen collected can vary (nasal swab, throat swab, saliva, etc.) depending on the testing method being used.
