Summary & Overview
HCPCS S0618: Audiometry for Hearing Aid Evaluation
HCPCS Level II code S0618 denotes audiometry performed specifically for hearing aid evaluation to determine the level and degree of hearing loss. This diagnostic test is central to decisions about hearing aid candidacy and device selection, making it important for patient care pathways and coverage determinations across the country. Nationally, audiometric evaluations influence access to amplification, device fitting workflows, and utilization of audiology services.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context of S0618, typical sites of service, and which payers commonly address coverage for hearing-aid-focused audiometry. The publication also outlines relevant benchmarks and policy considerations affecting coverage and billing practices, and provides guidance on where to find associated coding details.
The report is aimed at billing managers, audiologists, and policy analysts seeking clarity on the role of S0618 in clinical workflows and payer interactions. The content covers reimbursement benchmarks, applicable documentation expectations, and related coding considerations to help stakeholders align clinical documentation with payer requirements. Data not available in the input are noted where applicable.
Billing Code Overview

Clinical & Coding Specifications
Clinical Context
A 72-year-old patient presents to an audiology clinic with progressive difficulty hearing conversational speech, especially in noisy environments, and reports potential benefit from hearing amplification. The patient undergoes audiometry for hearing aid evaluation (S0618) to determine degree and configuration of hearing loss and to assess candidacy for amplification. The clinical workflow includes: initial intake and otologic history, otoscopic inspection to rule out cerumen impaction or conductive cause, pure-tone air and bone conduction thresholds, speech audiometry including speech recognition thresholds and word recognition scores, real-ear measurements or aided testing when appropriate, and counseling on results and amplification options. Documentation includes indications for testing, test type (S0618), test results (thresholds and speech scores), interpretation of degree/configuration of loss, recommendations (e.g., hearing aids, medical referral), and any applicable modifier (for example, modifier 26 when only the professional component interpretation is billed separately). Typical sites of service are outpatient audiology clinics, ENT offices, and ambulatory surgical centers when performed as part of a preoperative or specialty evaluation.
