The Audiology, Early and Periodic Screening, Diagnostic and Treatment (EPSDT) Audiology and Speech Therapy Code Conversion replaces HCPCS Level III codes, commonly referred to as local codes, with HIPAA-compliant CPT Category I or HCPCS Level II national codes. HIPAA mandated these changes to billing requirements for audiology, EPSDT audiology and speech therapy services.

For claims with dates of service on or after April 1, 2019, providers will use a combination of revenue codes and CPT Category I or HCPCS Level II codes; or revenue codes and CPT Category I or HCPCS Level II codes with modifier(s).

Billing instructions and Frequently Asked Questions (FAQs) will soon be available in the Audiology/EPSDT Audiology/Speech Therapy section of the HIPAA: Code Conversions web page. Additional information for this project will publish as details are determined.
