Hearing aid correction bandwidth

I notice when listening to a frequency sweep recording that I really can't hear anything above 10khz.  I also have a sharp 10 dB divot in my hearing at about 3,900 hz. Tinnitus in one ear, too.
Watching a few dozen YouTubes, I find the hearing aid companies appear to only measure and correct your hearing hearing between 250hz and 8khz.
So is there any help to get that top octave back?
