icd 9 code for otosclerosis of the anterior footplate of the stapes

What is the ICD-9 code for diagnosis?

ICD-9-CM 387.9 is a billable medical code that can be used to indicate a diagnosis on a reimbursement claim, however, 387.9 should only be used for claims with a date of service on or before September 30, 2015.

What is the pathophysiology of otosclerosis?

Formation of spongy bone in the labyrinth capsule which can progress toward the stapes (stapedial fixation) or anteriorly toward the cochlea leading to conductive, sensorineural, or mixed hearing loss. Several genes are associated with familial otosclerosis with varied clinical signs.

What is Otosclerosis H80?

Otosclerosis H80- >. Pathological condition of the bony labyrinth of the ear, in which there is formation of spongy bone; may cause bony ankylosis of the stapes, resulting in conductive hearing loss; cochlear otosclerosis may also develop, resulting in sensorineural hearing loss.

What is the ICD 9 code for otosclerosis?

387.9ICD-9-CM Diagnosis Code 387.9 : Otosclerosis, unspecified.

What is the ICD-10-CM code for otosclerosis?

Unspecified otosclerosis, bilateral H80. 93 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM H80. 93 became effective on October 1, 2021.

Which layer of otic capsule is involved in otosclerosis?

Otosclerosis, also called otospongiosis, is an abnormal bone remodeling in the middle ear in which a normal dense endochondral layer of bony otic capsule in the bony labyrinth is replaced by one or more foci of irregularly laid spongy bone and most commonly involves the stapes region.

Is otosclerosis unilateral or bilateral?

Otosclerosis typically presents as progressive bilateral conductive hearing loss in middle-aged white women. It is the leading cause of conductive hearing loss in adults who do not have a middle ear effusion or a history of otitis media.

What is the ICD 10 PCS code for stapedectomy left ear?

ICD-10-PCS 09W98JZ converts approximately to: 2015 ICD-9-CM Procedure 19.29 Other revision of stapedectomy.

What type of hearing loss is seen in otosclerosis?

Otosclerosis is a form of conductive hearing loss. In some cases, as the ear loses its ability to transmit sound, people may first notice low-frequency hearing loss, meaning that low-pitched sounds are harder to hear.

What is otosclerosis ear?

Otosclerosis is a condition in which there's abnormal bone growth inside the ear. It's a fairly common cause of hearing loss in young adults. There are 3 tiny bones deep inside the ear that vibrate when sound waves enter.

What is the procedure to correct for otosclerosis?

Otosclerosis surgery is called a stapedectomy (stay-puh-dek-tuh-mee). During this procedure, your surgeon places a prosthesis (replacement hearing bone) in your middle ear. This prosthesis bypasses the stapes bone, allowing sound waves to travel to the inner ear. As a result, hearing is improved.

What is otosclerosis caused by?

The exact cause of otosclerosis is unknown. It may be passed down through families. People who have otosclerosis have an abnormal extension of sponge-like bone growing in the middle ear cavity. This growth prevents the ear bones from vibrating in response to sound waves.

What are the stages of otosclerosis?

There appear to be three stages of otosclerosis -resorptive osteoclastic stages with signs of inflammation, followed by an osteoblastic stage involving immature bone, followed by mature bone formation.

What are the 4 types of hearing loss?

The Four Types of Hearing LossSensorineural Hearing Loss.Conductive Hearing Loss.Mixed Hearing Loss.Auditory Neuropathy Spectrum Disorder.Talk to Your Audiologist.

Is otosclerosis reversible?

Otosclerosis is a disease that causes progressive hearing loss. It is surgically reversible. Otosclerosis is a genetically transmitted disease (autosomal dominant inheritance) that affects the bone of middle and inner ear. It causes abnormal bone to deposit in the middle and inner ear.

What is otic capsule?

The bony labyrinth (also osseous labyrinth or otic capsule) is the rigid, bony outer wall of the inner ear in the temporal bone. It consists of three parts: the vestibule, semicircular canals, and cochlea. These are cavities hollowed out of the substance of the bone, and lined by periosteum.

Why does Carhart's Notch occur?

Carhart notch, described for the first time in 1950, involves a reduction in the bone curve by approximately 10 to 20 dB at a frequency of 2000 Hz. It arises as a result of mechanical immobilization of the stirrup base in the oval window and disturbances in the self-resonance of the ossicular chain.

What is high riding jugular bulb?

High riding jugular bulb is defined as an extension of the most cephalad portion of the Jugular bulb superior to the floor of the internal auditory canal or it can projects above the basal turn of the cochlea [2]. It could also be a diverticulum arising from the Jugular bulb.

Is oval window inner ear?

The oval window is the intersection of the middle ear with the inner ear and is directly contacted by the stapes; by the time vibrations reach the oval window, they have been amplified over 10 times from what they were when they contacted the tympanic membrane, a testament to the amplifying power of the middle ear.
