Disorders of vestibular function (H81)
Clinical Information
Benign Paroxysmal Positional Vertigo - Idiopathic recurrent VERTIGO associated with POSITIONAL NYSTAGMUS. It is associated with a vestibular loss without other neurological or auditory signs. Unlike in LABYRINTHITIS and VESTIBULAR NEURONITIS, inflammation in the ear is not observed.
Endolymphatic Hydrops - An accumulation of ENDOLYMPH in the inner ear (LABYRINTH) leading to buildup of pressure and distortion of intralabyrinthine structures, such as COCHLEA and SEMICIRCULAR CANALS. It is characterized by SENSORINEURAL HEARING LOSS; TINNITUS; and sometimes VERTIGO.
Hypohidrosis - Abnormally diminished or absent perspiration. Both generalized and segmented (reduced or absent sweating in circumscribed locations) forms of the disease are usually associated with other underlying conditions.
Ototoxicity - Damage to the EAR or its function secondary to exposure to toxic substances such as drugs used in CHEMOTHERAPY; IMMUNOTHERAPY; or RADIATION.
Vestibular Neuronitis - Idiopathic inflammation of the VESTIBULAR NERVE, characterized clinically by the acute or subacute onset of VERTIGO; NAUSEA; and imbalance. The COCHLEAR NERVE is typically spared and HEARING LOSS and TINNITUS do not usually occur. Symptoms usually resolve over a period of days to weeks.

Instructional Notations
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
