Hearing loss: code to ICD 10 — sensorineural and sensorineural
What is the hearing loss code disease in ICD 10
The term «deafness» refers to a disorder of perception of sounds and speech communication with others. According to statistics, the disease affects one in ten people on the planet. The severity of the disease ranges from partial hearing loss to absolute deafness.
In recent years, along with unilateral often observed bilateral hearing loss. Negative impact on the one hand may occur due to acoustic or direct trauma, falling into the ear foreign object, development of a unilateral otitis media. The bilateral form of the disease is diagnosed when negative processes are both hearing, disrupting the function of their items.
Classification of hearing loss according to ICD 10
International classification of diseases (ICD 10) helps to systematize statistical data on various diseases.
According to ICD-10 code H90 has hearing loss and is divided into three main groups:
- conductive hearing loss;
- sensorineural (sensorineural);
Conductive hearing loss
During conductive hearing loss impaired conduction of sound waves from the outer to the inner ear. The auditory ossicles are overgrown by bone tissue.
The causes of pathology are different:
- birth defects;
- disruption of the Eustachian tube.
For ICD 10 deafness conductive type is marked as:
- H90.0 — conductive bilateral hearing loss, which affects both the ear canal (considered a severe form of hearing loss);
- H90.1 — conductive hearing loss, unilateral with normal hearing on the opposite ear;
- H90.2 — conductive hearing loss unspecified (in this case, the cause is very difficult to establish).
In most cases, this form of the disease is treatable. For these purposes often surgery is carried out with replacement of the hearing bones in plastic or ceramic. The patient may be prescribed hearing AIDS.
If the hearing recovers, the patient may do without a hearing aid.
Sensorineural hearing loss
In sensorineural hearing loss there is a loss of sound apparatus: internal ear, vestibulocochlear nerve or the auditory center in the brain. People are hard of hearing or complaining of noise in the ears.
The main factors of pathology include:
- age-related changes;
- Meniere’s disease;
- deviations during pregnancy;
- neuritis of the auditory nerve.
Sensorineural hearing loss has two forms of development:
In the acute form the disease begins suddenly as a result of significant changes in the blood vessels of the inner ear. The patient has ringing in the ears and dizziness. For an accurate diagnosis is necessary to seem LOR-to the doctor.
On the development of the chronic stage of the disease is influenced by a variety of causes in which the violation of the blood vessels occurs gradually. The patient is hard of hearing, can’t understand speech, perceives tinnitus.
Code sensorineural (sensorineural) hearing loss, ICD-10 has additional marking:
- H90.3 — sensorineural hearing loss bilateral (therapy the patient is prescribed after establishing the cause);
- H90.4 — sensorineural hearing loss unilateral with normal hearing on the opposite ear (provoke the development of disease negative factors: cerumen, foreign object, trauma to the head, strong sound impact);
- H90.5 — sensorineural hearing loss unspecified (diagnosis is established after a full examination).
Mixed hearing loss
Deafness is of mixed type combines conductive and sensorineural hearing loss. Code according to ICD 10 has additional marking:
- H90.6 — mixed conductive and sensorineural hearing loss, bilateral;
- H90.7 — combined conductive and sensorineural hearing loss, unilateral with normal hearing on the opposite ear;
- H90.8 — mixed conductive and sensorineural hearing loss, unspecified.
Pathology has several forms of the flow:
- The sudden form occurs due to trauma, exposure to viruses, drugs. In most cases, when this form of hearing restored partially.
- The acute form occurs within days and lasts up to 7 days.
- The subacute form occurs in the patient from 7 days to one month.
- The chronic form is characterized by a gradual decrease in the perception of sounds and lasts from several months to several years.
Factors affecting the occurrence of deafness, mixed type, is still not fully elucidated. As the main highlight: inflammation of the ear with damage to the cochlea, age-related changes.
