Hearing Aids and Devices Including Wearable, Bone-Anchored, and Semi-Implantable (for Tennessee Only)

Coverage Summary

Scope: This policy applies to Tennessee Medicaid (TennCare) and CoverKids and only to individuals under 21 years of age. It covers wearable air-conduction hearing aids (ACHAs) as medically necessary, and a range of bone-conduction and semi-implantable devices (including non-implantable headband/adhesive bone conduction devices, partially or fully implantable bone-anchored systems, and semi-implantable electromagnetic middle-ear devices). The policy presents a mixed coverage stance: wearable ACHAs are proven and medically necessary; many bone-anchored and semi-implantable devices are covered when FDA-labeled indications are met or when the member is not a candidate for ACHAs; some technologies (intraoral bone conduction, laser/light-based aids, and totally implanted middle ear systems) are listed as unproven/not medically necessary.

Submit prior authorization when requesting an equipment upgrade.

Background & Evidence Summary

Background: The policy defines the major types of hearing loss—conductive (sound not conducted efficiently through outer/middle ear), sensorineural (SNHL) (inner ear or nerve pathway damage), and mixed (combination of conductive and sensorineural). Device types described include wearable air-conduction hearing aids (ACHAs), non-implantable bone conduction devices (headband/adhesive), partially implantable/sem i-implantable electromagnetic middle-ear devices, and implantable bone-anchored systems (percutaneous and transcutaneous). The evidence discussion emphasizes pediatric data and device trials where applicable (for example, studies and systematic reviews of bone-conduction devices and pediatric outcomes are summarized), noting variable quality and stronger pediatric emphasis for bone-conduction device evidence.

Evidence source	Summary
Cochrane (Ferguson et al. 2017)
Hearing aids effective for improving hearing-specific and general health-related quality of life and listening ability in adults with mild to moderate hearing loss (5 RCTs, 825 participants).
Multiple systematic reviews and cohort studies
Evidence supports benefit of bone conduction devices and semi-implantable implants in children/adults for indicated hearing loss, though quality and RCT data are limited for some devices (e.g., Bonebridge, pTCBIs).
BAHA Attract systematic review (Dimitriadis 2016)
10 studies, 89 cases; satisfactory hearing outcomes and low complication rate versus percutaneous devices; further robust trials needed.
Intraoral IOBC SoundBite (Gurgel 2015)
Prospective case series, 81 SSD patients, improved APHAB scores and high satisfaction; no serious adverse events; limitations: no control group, attrition.
Earlens CHA (Gantz 2017)
Single-arm trial 43 subjects (86 ears), 120 days, mean PTA4 change -0.40 dB (no loss), significant aided word recognition improvement; supported FDA clearance.
Totally implanted middle ear systems (systematic reviews and case series)
Mixed results with small samples: some improvements in functional gain and speech outcomes but higher complication rates, device failures, and insufficient high-quality evidence for definitive conclusions.

Definitions

Term	Definition
Conductive Hearing Loss
Occurs when sound is not conducted efficiently through the outer ear canal to the eardrum and the ossicles of the middle ear; often correctable medically or surgically.
Sensorineural Hearing Loss (SNHL)
Occurs when there is damage to the inner ear (cochlea) or nerve pathways; usually not medically or surgically correctable and is the most common type of permanent hearing loss.
Mixed Hearing Loss
Combination of conductive and sensorineural hearing loss—damage in outer/middle ear and inner ear or auditory nerve.
Hearing Aids
Sound-amplifying devices designed to aid people with hearing impairment; includes wearable, bone-anchored, and semi-implantable electromagnetic devices for purposes of this policy.
PTA
Pure tone average measured at specified frequencies (commonly 0.5, 1, 2, 3 kHz).
BC
Bone conduction.
AC
Air conduction.
SSD
Single-sided deafness: unilateral profound sensorineural deafness with normal hearing contralaterally.
