ICD10 code of Benign Paroxysmal Positional Vertigo and ICD9 code

The ICD-10-CM code for Benign Paroxysmal Positional Vertigo is H81.1, while the ICD-9-CM code historically used for this condition is 386.11. These codes are essential for clinicians to document Benign Paroxysmal Positional Vertigo accurately for medical billing and clinical record-keeping purposes.

What are the specific ICD codes for Benign Paroxysmal Positional Vertigo?

When seeking medical care, it is helpful to know that Benign Paroxysmal Positional Vertigo is classified under specific diagnostic codes. Under the ICD-10 system, H81.1 is further subdivided to specify the side affected: H81.11 for the right ear, H81.12 for the left ear, and H81.13 for bilateral involvement. In the older ICD-9 system, 386.11 was the universal code for Benign Paroxysmal Positional Vertigo.

What causes Benign Paroxysmal Positional Vertigo?

Benign Paroxysmal Positional Vertigo occurs when calcium carbonate crystals, known as otoconia, become dislodged from their normal position in the utricle and migrate into the semicircular canals of the inner ear. When you move your head, these displaced crystals shift, creating a false sensation of movement. Benign Paroxysmal Positional Vertigo is most common in individuals over the age of 50, though it can occur at any age.

How is Benign Paroxysmal Positional Vertigo diagnosed?

Physicians typically diagnose Benign Paroxysmal Positional Vertigo through a physical examination, most notably the Dix-Hallpike maneuver. This test involves specific head positioning to trigger symptoms and observe nystagmus (involuntary eye movement). Common diagnostic criteria include:

• Brief episodes of vertigo triggered by changes in head position.


• Characteristic nystagmus observed during positional testing.


• Absence of neurological symptoms, such as hearing loss or numbness, which would suggest a different condition.

Next steps

• Consult an otolaryngologist (ENT) or a vestibular physical therapist for a definitive diagnosis.


• Request the Epley maneuver, a common canalith repositioning procedure used to treat Benign Paroxysmal Positional Vertigo.


• Connect with the 18 members in the DiseaseMaps.org community to share experiences and coping strategies.


• Keep a symptom log to track the frequency and triggers of your vertigo episodes.
