Labyrinthine fistula
ICD-10 H83.1 is a billable code used to indicate a diagnosis of labyrinthine fistula.
Labyrinthine fistula is an abnormal connection between the inner ear (labyrinth) and the surrounding structures, often resulting from chronic otitis media or trauma. This condition can lead to a range of symptoms, including hearing loss, vertigo, and tinnitus. The fistula allows perilymph fluid to leak from the inner ear into the middle ear, which can exacerbate hearing impairment and balance issues. Clinically, patients may present with sudden changes in hearing, episodes of dizziness, or a sensation of fullness in the ear. Diagnosis typically involves audiometric testing, imaging studies such as CT or MRI, and sometimes a fistula test, where pressure is applied to the ear to observe for changes in symptoms. Management may include surgical intervention to repair the fistula, particularly if conservative measures fail. The prognosis varies depending on the underlying cause and the timeliness of treatment.
Detailed clinical history, results of audiometric tests, imaging studies, and surgical notes.
Patients presenting with chronic ear infections, sudden hearing loss, or vertigo.
Ensure all diagnostic tests and treatments are clearly documented to support the diagnosis.
Comprehensive audiological evaluations and reports on hearing function.
Assessment of hearing loss in patients with suspected labyrinthine fistula.
Document the correlation between audiometric findings and clinical symptoms.
Used when surgical intervention is performed to repair the fistula.
Operative report detailing the procedure and findings.
Otolaryngologists must ensure all surgical details are documented for accurate coding.
Common causes include chronic otitis media, head trauma, and surgical complications. These factors can lead to a breach in the bony labyrinth, resulting in a fistula.
