The Healthcare Common Procedure Coding System (HCPCS) is comprised of two levels. Level II codes are:

Level II codes of the Healthcare Common Procedure Coding System (HCPCS) are designated as national codes that are used to identify products, supplies, and services not included in the CPT (Current Procedural Terminology) codes. This includes items such as durable medical equipment, prosthetics, orthotics, and certain drugs administered in a physician's office or hospital. Level II codes are crucial for standardizing billing for various healthcare services and items for Medicaid and Medicare.

These national codes ensure that medical billing is consistent across providers and facilitates communication within the healthcare system. Each Level II code starts with a letter followed by four numeric digits, making them distinct from CPT codes. Understanding the structure and purpose of these codes is essential for anyone working in medical administration, particularly in coding and billing functions.
