Description
The Level II HCPCS codes, which are established by CMS's Alpha-Numeric Editorial Panel, primarily represent items and supplies and non-physician services not covered by the American Medical Association's Current Procedural Terminology-4 (CPT-4) codes; Medicare, Medicaid, and private health insurers use HCPCS procedure and modifier codes for claims processing. Level II alphanumeric procedure and modifier codes comprise the A to V range.
