Datasets / HCPCS Level II — Healthcare Common Procedure Coding System

Meridian maintains this dataset from the Centers for Medicare & Medicaid Services’ public files, and holds the cms namespace until the Centers for Medicare & Medicaid Services claims it.

Two parts of CMS's file are not CMS's own work and are left out. The dental codes (the D series) are the American Dental Association's Current Dental Terminology (CDT), and CPT is the American Medical Association's: no CPT code appears, the cross-references CMS points at CPT codes are dropped, and where one of CMS's descriptions cites a CPT code by number, the number reads [CPT code] and text_source is cms_cpt_redacted.

The list keeps terminated codes. A code can be used on a date when its added_date is on or before that date and its termination_date, the last date it may be used, is empty or on or after it. Modifiers are not included.

The Centers for Medicare & Medicaid Services maintains HCPCS Level II, and here each row is one of its alpha-numeric billing codes.^[1]^[2] Each HCPCS Level II code is a single letter followed by four digits.^[1]

About

HCPCS Level II, the alpha-numeric codes the Centers for Medicare & Medicaid Services (CMS) maintain for billing supplies, drugs, equipment and services that CPT does not cover: one row per code in CMS's quarterly file, current and terminated, with its long and short description, the dates CMS added, last changed and terminated it, and CMS's pricing, coverage, BETOS and type-of-service fields. Each snapshot records CMS's quarter and the date of its file. Public domain (Centers for Medicare & Medicaid Services).

Background

How HCPCS Level II relates to CPT (Level I)

HCPCS is divided into two main subsystems, Level I and Level II.^[1] HCPCS Level I is Current Procedural Terminology (CPT), a numeric coding system maintained by the American Medical Association.^[1] CPT codes are used primarily to identify medical services and procedures furnished by physicians and other health care professionals.^[1]

HCPCS Level II codes were established so providers and suppliers can submit claims for services, supplies and equipment that CPT codes do not identify.^[1]^[3] A HCPCS Level II code, also known as an alpha-numeric code, is a single letter followed by four numeric digits.^[1]

Who uses it

Medicare and other insurers cover a variety of services, supplies and equipment that CPT codes do not identify, and HCPCS Level II codes let providers and suppliers bill for them.^[1] HCPCS Level II is a system for identifying items and certain services, not a methodology for making coverage or payment determinations.^[3] The existence of a HCPCS Level II code does not, of itself, determine coverage or non-coverage for an item or service.^[3] Read a code as the name of an item, not as a promise that anyone will pay for it. (Meridian's view)

A HCPCS termination date is the last date for which a code may be used by Medicare providers.^[4]

Anyone may submit a request to modify the HCPCS Level II national code set.^[1]^[3]

Where it comes from

The HCPCS Level II coding system began in the 1980s.^[1]

HCPCS once had a third level of local codes, developed by state Medicaid agencies, Medicare contractors and private insurers for use in specific programs and jurisdictions.^[5] The use of HCPCS Level III codes was discontinued on December 31, 2003.^[5]
