Final answer:
A Medicare HCPCS code number is used for billing medical services and procedures, such as 'A0426' for non-emergency ambulance service with advanced life support.
Step-by-step explanation:
An example of a Medicare HCPCS code number could be a code from the group of codes used for billing and coding medical services and procedures for Medicare patients. The HCPCS (Healthcare Common Procedure Coding System) is divided into two levels: Level I is the American Medical Association's Current Procedural Terminology (CPT) codes, and Level II includes codes for products, supplies, and services not included in CPT, such as durable medical equipment and drugs.
A sample HCPCS code from Level II might look like 'A0426' which stands for Ambulance service, advanced life support, non-emergency transport, level 1 (ALS1).
