What type of services would be coded with "A" codes?

The "A" codes within the Healthcare Common Procedure Coding System (HCPCS) specifically designate ambulance services and non-physician health services. These codes are utilized to document a range of transportation-related services as well as various non-physician services that are essential for patient care.

Ambulance services are categorized under "A" codes because they pertain to the transport of patients to and from medical facilities, ensuring that individuals receive necessary medical attention. This could include emergency and non-emergency transport and is critical for maintaining continuity of care.

Non-physician health services include services provided by healthcare professionals who are not physicians, such as physical therapists, occupational therapists, and speech-language pathologists. These services play a vital role in a patient's holistic treatment plan and are accordingly captured using "A" codes to ensure accurate billing and documentation.

The other options pertain to categories of services that are coded differently within the HCPCS system, reflecting the specific focus and requirements of those types of care.
