As of November 2019, the cost of a cochlear implant is approximately 200,000 to 500,000 yuan, including medical expenses and device fees.
Medical expenses: including hospitalization fees, surgery fees, medicines, adjustment fees, surgical complications treatment fees and rehabilitation treatment fees, etc., are about ten to two hundred thousand.
Device cost: Generally, domestically produced cochlear implants cost around RMB 70,000 to RMB 80,000, while imported cochlear implants cost around RMB 10,000 to 300,000. Cochlear implant is an electronic device that uses an external speech processor to convert sound into a certain coded form of electrical signals. It directly excites the auditory nerve through an electrode system implanted in the body to restore or reconstruct the auditory function of deaf people.

Post-implantation adjustment:
Switch-on is performed one month after the cochlear implant surgery. Because different cochlear implant devices have different design principles, they use different adjustment hardware and software, as well as different adjustment methods, adjustment processes, and adjustment parameters.
Cochlear implant devices include an implant inside the body and a speech processor outside the body. Mapping is a process in which professionals use computers and specialized equipment to adjust the parameters of each cochlear implant device to provide the most comfortable and effective stimulation for the patient and allow the patient to hear various sounds comfortably.
The speech processor will not work unless a professional adjusts the machine to set appropriate values ??in a series of parameters. Parameters that need to be adjusted after cochlear implantation include: speech encoding schemes such as SPEAK, CIS, and ACE schemes; electrical stimulation modes, including unipolar stimulation, bipolar stimulation, and ground mode.
The channels used can be selected from 1 to 22 channels. The frequency distribution of the channel filter output is to allocate the frequency range of 200Hz to 8kHz to each channel; the threshold (T value) of each channel can produce auditory stimulation. the minimum stimulation level); the maximum comfortable stimulation of each channel (the maximum comfortable stimulation that the C value allows the patient to feel).
