The HCPCS Level II coding system is a comprehensive and standardized system that classifies similar products that are medical in nature into categories for the purpose of efficient claims processing. For each alphanumeric HCPCS code, there is descriptive terminology that identifies a category of like items. These codes are used primarily for billing purposes.
HCPCS Level II codes are divided into 17* sections, each based on an area of specialty, like Medical & Laboratory or Rehabilitative Services.
* D-Codes are not listed on this site. The Centers for Medicare and Medicaid Services (CMS) is no longer including the D codes as part of the HCPCS Level II code set effective January 1, 2011. These codes are published and maintained by the American Dental Association and can be obtained through that association.
