VA Disability Rating for Cochlear Implant: Exam, SMC, and TDIU

A cochlear implant does not have its own VA disability rating. The VA disability rating for a cochlear implant is calculated under the standard hearing loss formula in 38 CFR 4.85, using audiometric test results plotted on two tables. Because implants are provided only for severe to profound hearing loss, the ratings that come out of that formula tend to be high, and a 100% schedular rating for bilateral hearing loss is possible after implant surgery.¹

How the Rating Is Calculated

The rating is mechanical. A state-licensed audiologist performs puretone audiometry and the Maryland CNC speech discrimination test, and the numbers are dropped into a formula the rater cannot deviate from.² The Board of Veterans’ Appeals has described the process as a “mechanical application of the rating schedule to the numeric designations derived from the results of audiometric evaluations.”¹

The formula runs in two steps. First, the puretone threshold average for each ear is calculated by adding the thresholds at 1000, 2000, 3000, and 4000 Hertz and dividing by four. That average, combined with the speech discrimination score, is plotted on Table VI to produce a Roman numeral designation from I (mildest) to XI (most profound). If speech discrimination cannot be reliably tested, Table VIa is used instead, based on the puretone average alone.³

Second, the two Roman numerals are crossed on Table VII, and the intersection is your percentage rating. If only one ear’s hearing loss is service-connected, the other ear is assigned a Level I designation for that calculation regardless of its actual hearing.²

An additional rule at 38 CFR 4.86 covers exceptional patterns. If puretone thresholds are 55 decibels or more at all four tested frequencies, or if the threshold is 30 decibels or less at 1000 Hz but 70 decibels or more at 2000 Hz, a modified formula applies that can push the affected ear into a higher Roman numeral.⁴

Is the Exam Done With the Implant On or Off?

This is the question that decides the rating for most implant recipients. Under 38 CFR 4.85, hearing exams for rating purposes are conducted “without the use of hearing aids.” The regulation does not explicitly address cochlear implants, which are surgically implanted rather than removable.²

The BVA has treated the underlying hearing loss, not the assisted hearing, as the thing being rated. In one case a January 2017 examination could not test puretone thresholds or speech discrimination in the implanted ear because of a recent surgery, and the Board presumed Level XI hearing acuity, the most profound designation, for that ear. The Board in the same case rejected private examinations because the examiners failed to use the Maryland CNC word list or had performed testing while the veteran was wearing his cochlear implant.⁵

VHA clinical guidelines do call for postoperative speech recognition testing “while veteran is fit with best map in speech processor,” but those guidelines govern clinical care and outcome measurement, not the Compensation and Pension exam that produces the disability rating.⁶ If the C&P audiologist tests you with the processor active and reports scores that reflect assisted hearing, the resulting rating will understate your disability, and the exam may be inadequate for rating purposes.

One Ear or Both

Each ear is evaluated independently, and the Table VII combination is what drives the percentage. A veteran with an implant in one ear and useful hearing in the other will get a lower rating than a veteran who is profoundly deaf in both. Where hearing loss is service-connected in only one ear, the non-service-connected ear takes a Level I designation, which limits how high the combined rating can go. Bilateral implantation within the VA is generally sequential rather than simultaneous and is evaluated case by case.⁷

Temporary 100% Rating During Recovery

A temporary total rating during convalescence from cochlear implant surgery is available under 38 CFR 4.30. That regulation authorizes a temporary 100% evaluation when surgery for a service-connected disability results in at least one month of convalescence, severe postoperative residuals such as incompletely healed wounds or house confinement, or immobilization of a major joint by cast.⁵

It is not automatic. In a 2022 decision the Board remanded a veteran’s 4.30 claim because the record did not establish whether his cochlear implant surgeries, and later removal surgeries, actually required at least one month of convalescence or produced severe postoperative residuals. The Board stated it was “unsure, based on the current evidence of record, as to whether such a surgery can award a temporary total evaluation” without a medical determination on those specific points, and ordered a retrospective medical opinion.⁵ To pursue a temporary total, get a written statement from your surgeon addressing convalescence time and residuals in the language the regulation uses.

Ratings You May Qualify for Alongside Hearing Loss

Secondary Conditions

Inner ear damage that leads to cochlear implantation often produces conditions ratable in their own right. The 2022 BVA case identified “peripheral vestibular disorder to include vertigo, balance disturbance, and right semicircular canal dehiscence” as ratable disabilities secondary to the veteran’s hearing loss, and those secondary ratings were combined with the hearing rating for purposes of Individual Unemployability.⁵ Common companions to profound hearing loss include vertigo, balance disorders, Meniere’s disease, and peripheral vestibular disorders. Tinnitus is typically rated at 10% under Diagnostic Code 6260. A secondary claim needs a current diagnosis, treatment records, and a medical nexus opinion linking the secondary condition to the already service-connected hearing loss.

Special Monthly Compensation for Deafness

Special Monthly Compensation under 38 U.S.C. § 1114(k) is available for bilateral deafness. Under 38 CFR 3.350(a)(5), that means hearing loss “equal to or greater than the minimum bilateral hearing loss required for a maximum rating evaluation under the rating schedule,” which generally requires the absence of air and bone conduction.⁵

Whether an implant recipient keeps SMC after surgery is not fully settled. In the 2022 BVA case the Board observed that the veteran’s hearing was “mildly improved with the cochlear implant” but “not to the level that he could return to work and function appropriately.” The Regional Office had awarded him SMC based on deafness in both ears effective March 2019. Mild functional improvement from an implant does not by itself eliminate SMC eligibility.

TDIU

Total Disability based on Individual Unemployability is available when service-connected disabilities prevent substantially gainful employment. Schedular TDIU requires either one condition rated at 60% or a combined rating of 70% with one condition at 40% or higher. Veterans who fall short of those thresholds can pursue extraschedular TDIU by showing their specific disabilities keep them out of work.¹ Occupation matters. A job that requires full hearing strengthens the claim. Where hearing loss is one of several service-connected conditions, they can support TDIU together. In one case the BVA had to remand the TDIU question for the pre-surgery period because the examiner had addressed only post-implant employability.

What to Bring to the C&P Exam

The VA generally requires a current diagnosis, evidence of an in-service event that could have caused the disability, and a medical opinion linking the two.⁸ For a hearing claim built around a cochlear implant, submit your audiological test results, treatment records, and the operative reports from your implant surgery. Your own provider can complete a Disability Benefits Questionnaire, though the VA does not reimburse private exams.⁹

At the C&P exam, confirm that the audiologist uses puretone audiometry and the Maryland CNC word list, and clarify how the implanted ear will be tested; a report based on hearing with the processor active will not capture the underlying loss the rating schedule is designed to measure. Exam results are not given at the appointment, and you must request the final report by submitting VA Form 20-10206.⁹
