Cochlear Implantation

The Ohio Academy of Audiology (OAA) is an organization representing approximately 1100 audiologists in the state of Ohio. On behalf of OAA I would like to commend and thank you for considering the proposed expansion of coverage for cochlear implantation (CI) for adults with aided open-set sentence recognition scores of less than or equal to 60% (up from 40%) on recorded tests. The OAA is an organization committed to improving quality of life for individuals with balance and communication disorders; audiologists are the primary health-care professionals who evaluate, diagnose, treat, and manage hearing loss and balance disorders in individuals of all ages.

As stated in our initial letter of support regarding this proposed expansion, by approving this expansion of coverage, Medicare Part B beneficiaries will be afforded the same opportunities for improvement in communication, tinnitus, depression, cognition and social isolation as individuals with commercial insurance. It has been reported by the members of OAA that they must often inform their Medicare Part B patients that they meet FDA labeling criteria for cochlear implantation; however, Medicare Part B will not cover the cost of cochlear implantation which has great potential to improve their ability to hear and communicate, in turn improving their quality of life. This leaves their patients and their family members frustrated, depressed and seeking other opportunities for hearing improvement that are not as effective. By approving this expansion, you are providing our patients with hope for enhanced ability to communicate and improved quality of life. If you have questions about these comments, or OAA’s support of the larger American Academy of Audiology/American Academy of Otolaryngology document submitted, please feel free to contact me.

National Center for Health Research’s Comments On Broadening the National Coverage for Cochlear Implantation

We are writing to express our views on the Centers for Medicare and Medicaid Services (CMS) proposed decision memo reconsidering the national coverage determination for cochlear implantation.

The National Center for Health Research (NCHR) is a nonprofit think tank that conducts, analyzes, and scrutinizes research on a range of health issues, with particular focus on which prevention strategies and treatments are most effective for which patients and consumers. We do not accept funding from companies that make products that are the subject of our work, so we have no conflicts of interest.

We agree that cochlear implants have been shown to improve sentence recognition, thus helping affected adults communicate better and reducing feelings of isolation [1,2]. However, there are several issues that we strongly urge CMS to consider before deciding whether to broaden the national coverage.

We are especially concerned about the high percentage (13%) of adverse events for cochlear implantation, which can include minor infections and vertigo, to more serious infections like Meningitis [1, 3]. Even relatively minor adverse events such as taste disturbances and tinnitus can affect a person’s quality of life. Moreover, 2.7% of the reported adverse events can have life-altering consequences, such as permanent facial paralysis or loss of pre-operative functional acoustic hearing [1, 3]. We are concerned that the CMS decision memo did not include information from the FDA’s website regarding the numerous risks of cochlear implants, or about the previous recalls of cochlear implants that were found to cause permanent damage. In fact, when we analyzed the number of adverse events reported to the FDA’s MAUDE adverse event reporting system we saw thousands of adverse event reports, including more than 4,000 adverse events reported to the FDA in 2021 alone; approximately 2,000 from device malfunctions and more than 2,000 reported patient injuries. Tragically, more than 50 deaths have been reported to the FDA by health professionals and others that were attributed to cochlear implants. Although the adverse event reports to the FDA are not always confirmed by medical records, it is a voluntary reporting system that is considered to be “the tip of the iceberg” for any medical device, since many surgeons and other medical professionals are reluctant to take the time to report any but the more serious adverse events where the medical device seems clearly to blame.

All the statistics we cited above could be acceptable if there were adequate data on whether specific demographic or medical traits put Medicare beneficiaries at higher or lower risk. Unfortunately, as CMS points out, there is not enough research on which traits or pre-existing risk factors cause a greater chance of failure of the cochlear implantation and who is most at-risk for having severe complications. Moreover, even though these are life-long devices, there was insufficient long-term data on cochlear implants that are implanted for more than 2 years. Filling in these research gaps is vital to enable providers and patients to make educated decisions about whether the benefits outweigh the risks for them, which is essential information for adults whose hearing disability is less harmful to their quality of life.

We strongly urge CMS to require the makers of cochlear implants to gather this information prior to CMS making a decision of whether and under what conditions to broaden coverage to those who’s sentence recognition score is below 60%, and to those who do not meet clinical criteria but are involved in Category B IDE Studies or Routine Cost Trials. The companies need to have the incentive to conduct this research, and they will not have that incentive if the national coverage determination is expanded without that data. We are concerned that broadening coverage without more precise information about which patients are likely to be at greatest risk of serious adverse events would make it very difficult for patients with less severe hearing loss to make informed decisions about whether the benefits outweigh the risks for them. We do not oppose broadening the coverage when it is possible to provide more meaningful information to patients and providers about the short-term and long-term risks for patient subpopulations. If data become available that would reduce the chances of serious adverse events, broadening coverage could help to reduce hospitalization, death, falls, dementia and depression reported for older persons with severe hearing loss that cannot be corrected by hearing aids [1,4].

In addition, we urge CMS to clarify whether any broadening of coverage would also include broadening access to all necessary aspects of proper usage of cochlear implants, including follow-up appointments and specialists needed in the recovery process. CMS should also clarify the required qualifications for implantation. For example, CMS states that patients need to demonstrate “a willingness to undergo an extended program of rehabilitation”. However, patients may not be perceived as willing if they cannot take time off for all the recommended appointments, cannot drive due to other impairments, or live in rural areas that are far from the services needed. Additional resources should be made available to reduce discrimination against patients who may be perceived as unwilling or ineligible through no fault of their own.

I support the proposed expansion of cochlear implantation coverage to less than or equal to 60% correct in the best-aided listening condition on tape-recorded tests of open-set sentence recognition. This change will better align CMS indications of cochlear implantation to those of the Food and Drug Administration and private insurers. The potential societal benefits are tremendous: the research literature is inundated with the realization of the negative impacts of hearing loss, including cognitive decline, social isolation, and mental unhealthiness, and these consequences can be curtailed with the appropriate intervention and patient-centered decision making. Increasing the criterion threshold to less than or equal to 60% correct will empower beneficiaries with significant hearing loss to regain control of their life and enjoy the life they envision, as well as increase the overall quality of life for themselves and their loved ones.

Dear Director Syrek Jensen:

On behalf of Cochlear Americas (Cochlear), we appreciate the opportunity to provide comments on the Centers for Medicare & Medicaid Services’ (CMS’s) Proposed Decision Memo that would revise National Coverage Determination (NCD) 50.3 for Cochlear Implantation (CAG-00107R). For over 40 years, Cochlear has been a global leader in implantable hearing solutions. Our goal is to deliver value by helping more people to hear, which contributes to building a healthier and more productive society.

We appreciate the time and effort CMS has put in to analyzing the clinical literature and data and engaging with stakeholders to address the outdated coverage criteria in NCD 50.3, which, as CMS is aware, was last updated nearly two decades ago. As we previously commented, cochlear implant technology has improved considerably in the intervening 17 years. Advances in implant technology and sound processing strategies have resulted in progressively improved outcomes and
