Benign paroxysmal vertigo
ICD-10 H81.1 is a billable code used to indicate a diagnosis of benign paroxysmal vertigo.
Benign paroxysmal vertigo (BPV) is a vestibular disorder characterized by brief episodes of vertigo triggered by changes in head position. It is caused by dislodged otoliths (calcium carbonate crystals) that migrate into the semicircular canals of the inner ear, leading to abnormal signals sent to the brain regarding head position and movement. Patients typically experience sudden, intense spinning sensations that can last from a few seconds to a couple of minutes. Symptoms may be exacerbated by specific head movements, such as rolling over in bed or looking up. Diagnosis is primarily clinical, supported by the Dix-Hallpike maneuver, which can reproduce the vertigo and nystagmus associated with BPV. Management often includes vestibular rehabilitation therapy and the Epley maneuver, which aims to reposition the dislodged otoliths. BPV is considered benign as it is not associated with any serious underlying condition, but it can significantly impact quality of life due to the unpredictable nature of vertiginous episodes.
Detailed history of vertiginous episodes, results of vestibular testing, and treatment plans.
Patients presenting with recurrent vertigo, particularly after head movements.
Ensure documentation includes specific maneuvers performed and patient response.
Comprehensive neurological examination findings and differential diagnosis considerations.
Patients with vertigo who may have underlying neurological conditions.
Document any neurological signs that may suggest a more serious condition.
Used to assess vestibular function in patients with vertigo.
Document the type of tests performed and results.
Otolaryngologists often perform these tests to confirm BPV.
Common triggers include sudden head movements, such as turning over in bed, looking up, or bending down. These movements can cause dislodged otoliths to stimulate the vestibular system, leading to vertigo.
