Medical Coding Practice Test 2025 – 400 Free Practice Questions to Pass the Exam

The HCPCS (Healthcare Common Procedure Coding System) is the coding system specifically designed for supplies, non-physician services, and other items that are not covered under CPT. It provides codes for various types of medical services and items, including durable medical equipment (DME), prosthetics, orthotics, and other supplies that patients may require outside of inpatient settings.

In addition to the Level I codes, which are based on the CPT system, HCPCS also includes Level II codes that are unique to the healthcare continuum. This makes HCPCS particularly comprehensive for capturing a wide range of services and supplies delivered by healthcare professionals, which may not be adequately described by the other coding systems.

CPT (Current Procedural Terminology) primarily focuses on services and procedures performed by physicians and is less comprehensive in terms of supplies and non-physician services. The ICD (International Classification of Diseases) is used to code diagnoses and diseases, while DRG (Diagnosis-Related Group) is a classification system used to categorize hospitalization costs and determine how much to pay for a patient's hospital stay based on the diagnosis. Therefore, HCPCS stands out as the correct choice for coding supplies and non-physician services.
