 description | The Value Set is a combination of two Code Systems: CPT (HCPCS I) and HCPCS II procedure code modifiers. Modifiers help further describe a procedure code without changing its definition.
The target set for this value set are the procedure code modifiers from the CPT and HCPCS files.
The Current Procedural Terminology (CPT) code set, created and maintained by the American Medical Association, is the language of medicine today and the code to its future. This system of terminology is the most widely accepted medical nomenclature used to report medical procedures and services under public and private health insurance programs. CPT coding is also used for administrative management purposes such as claims processing and developing guidelines for medical care review. Each year, via a rigorous, evidence-based and transparent process, the independent CPT Editorial Panel revises, creates or deletes hundreds of codes in order to reflect current medical practice.
Designated by the U.S. Department of Health and Human Services under the Health Insurance Portability and Accountability Act (HIPAA) as a national coding set for physician and other health care professional services and procedures, CPT’s evidence-based codes accurately encompass the full range of health care services.
All CPT codes are five-digits and can be either numeric or alphanumeric, depending on the category. CPT code descriptors are clinically focused and utilize common standards so that a diverse set of users can have common understanding across the clinical health care paradigm.
There are various types of CPT codes:
**Category I:** These codes have descriptors that correspond to a procedure or service. Codes range from 00100–99499 and are generally ordered into sub-categories based on procedure/service type and anatomy.
**Category II:** These alphanumeric tracking codes are supplemental codes used for performance measurement. Using them is optional and not required for correct coding.
**Category III:** These are temporary alphanumeric codes for new and developing technology, procedures and services. They were created for data collection, assessment and in some instances, payment of new services and procedures that currently don’t meet the criteria for a Category I code.
**Proprietary Laboratory Analyses (PLA) codes:** Recently added to the CPT code set, these codes describe proprietary clinical laboratory analyses and can be either provided by a single (solesource) laboratory or licensed or marketed to multiple providing laboratories that are cleared or approved by the Food and Drug Administration (FDA)). This category includes but is not limited to Advanced Diagnostic Laboratory Tests (ADLTs) and Clinical Diagnostic Laboratory Tests (CDLTs), as defined under the Protecting Access to Medicare Act of 2014 (PAMA).

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.
