Abstract
The safety, efficacy, and success of cochlear implants (CIs) are well established and have led to changes in criteria used by clinicians to determine who should receive a CI. Such changes in clinical decision-making have out-paced the slower-occurring changes that have taken place with regulatory bodies' and insurers' indications. We review the historical development of indications for CIs, including those of the U.S. Food and Drug Administration (FDA), Medicare, Medicaid, and private insurers. We report on expansion to include patients with greater residual hearing, such as those who receive Hybrid and EAS devices, and report on recent FDA approvals that place less emphasis on the patient's best-aided condition and greater emphasis on the ear to be treated. This includes expansion of CIs to patients with single-side deafness and asymmetric hearing loss. We review changes in the test materials used to determine candidacy, including transition from sentences in quiet to sentences in noise to the recent use of monosyllabic words and cognitive screening measures. Importantly, we discuss the recent trend to recommend CIs despite a patient not meeting FDA or insurers' indications (a practice known as "off-label"), which serves as attestation that current indications need to be updated.

| Device | Audiometric indications | Speech recognition indications |
|---|---|---|
| Advanced Bionics HR90K Ultra 3D | Severe to profound, bilateral sensorineural hearing loss (>70 dB HL) | ≤50% for open-set sentence recognition (HINT sentences) |
| Cochlear Profile and Profile Plus | Moderate to profound hearing loss in the low frequencies and profound (≥ 90 dB HL) hearing loss in the mid to high frequencies | ≤50% in the ear to be implanted (≤60% in the best-aided condition) on recorded tests of open-set sentence recognition |
| Cochlear Hybrid—L24 | Thresholds ≤ 60 dB HL through 500 Hz and ≥70 dB HL for 2,000 Hz + | ≤60% CNC word recognition in the ear to be implanted, ≤80% CNC in contralateral ear |
| MED-EL Synchrony and Synchrony 2 | Bilateral severe to profound sensorineural hearing loss (pure tone average ≥ 70 dB HL) | ≤40% in best-aided listening condition on recorded tests of open-set sentence recognition (HINT sentences) |
| MED-EL Synchrony and Synchrony 2 EAS | Thresholds ≤65 dB HL through 500 Hz and ≥ 70 dB HL for 2,000+ | ≤60% CNC word recognition in the ear to be implanted and in the contralateral ear |
| MED-EL Synchrony and Synchrony 2 for single-side deafness | Thresholds ≥90 dB HL in the ear to be implanted and normal hearing or mild sensorineural hearing loss in the other ear | <5% CNC word recognition in the ear to be implanted |
| MED-EL Synchrony and Synchrony 2 for asymmetric hearing loss | Thresholds ≥90 dB HL in the ear to be implanted and mild to moderately severe sensorineural hearing loss in the other ear, with a difference of at least 15 dB in pure tone averages between ears | <5% CNC word recognition in the ear to be implanted |
| Oticon Neuro System | Severe to profound hearing loss (pure tone average ≥ 70 dB HL at 500, 1,000, and 2,000 Hz) | 50% or less on HINT sentences in quiet or noise, in the best-aided listening condition |
