Anosmia

| ICD-10 from 2011 - 2016

R43.0 is a billable ICD code used to specify a diagnosis of anosmia. A 'billable code' is detailed enough to be used to specify a medical diagnosis.


The ICD code R430 is used to code Anosmia

Anosmia (/ænˈɒzmiə/) is the inability to perceive odor or a lack of functioning olfaction—the loss of the sense of smell. Anosmia may be temporary, but some anosmia (including traumatic anosmia) can be permanent. Anosmia is due to a number of factors, including an inflammation of the nasal mucosa, blockage of nasal passages or a destruction of one temporal lobe. Inflammation is due to chronic mucosa changes in the paranasal sinus lining and the middle and superior turbinates. Since anosmia causes inflammatory changes in the nasal passageways, it is treated by simply reducing the presence of inflammation. It can be caused by chronic meningitis and neurosyphilis that would increase intracranial pressure over a long period of time, and in some cases by ciliopathy including ciliopathy due to primary ciliary dyskinesia (Kartagener syndrome, Afzelius' syndrome or Siewert's syndrome). Many patients may experience unilateral anosmia, often as a result of minor head trauma. This type of anosmia is normally only detected if both of the nostrils are tested separately. Using this method of testing each nostril separately will often show a reduced or even completely absent sense of smell in either one nostril or both, something which is often not revealed if both nostrils are simultaneously tested.
