What section would you use in the CPT coding book to bill for an audiologist?

Section 1861(ll)(3)of the Social Security Act (the Act) defines "audiology services" as such hearing and balance assessment services furnished by a qualified audiologist as the audiologist is legally authorized to perform under State law (or the State regulatory mechanism provided by State law), as would otherwise by covered if furnished by a physician. In this section, these hearing and balance assessment services are termed "audiology services," regardless of whether they are furnished by an audiologist, physician, nonphysician practitioner (NPP), or hospital.
