Which healthcare items are specifically excluded from Level II codes?

The correct answer highlights that D series codes are specifically excluded from Level II codes. In HCPCS Level II coding, D series codes refer to specific items used in dental procedures. These codes are distinct from other categories in HCPCS, as they are focused on services that are primarily dental in nature rather than medical. This exclusion underscores that the HCPCS Level II coding system is designed for non-dental medical services and supplies, which means that dental services are coded differently, often relying on the Current Dental Terminology (CDT) codes.

In contrast, the other options are not excluded from Level II codes. Surgical procedures are typically coded under Current Procedural Terminology (CPT) codes, not under Level II. Alphabetic modifiers are used in conjunction with CPT and HCPCS codes to provide additional information but are not excluded from Level II; they are integral for clarifying the services or supplies provided. Non-covered medical supplies are also not excluded; they can have HCPCS codes, but they simply might not be reimbursed by certain payers. Thus, understanding the specifics of Level II coding helps in correctly applying coding principles and distinguishing what falls under its jurisdiction.
