Coverage Criteria for Nonpharmacologic Vertigo Treatments

Particle repositioning maneuvers (Epley, Semont)

Covered when ALL of the following are met

BPPV particle repositioning criteria: 1) Clinical diagnosis of benign paroxysmal positional vertigo (BPPV) confirmed by a positive diagnostic maneuver; 2) For posterior-canal BPPV: positive Dix-Hallpike maneuver characterized by reproduced vertigo with mixed torsional and vertical nystagmus, a latency period between completion of the maneuver and onset of vertigo/nystagmus, and brief duration of symptoms (typically <60 seconds); 3) For lateral (horizontal) canal BPPV: positive supine roll test characterized by positional horizontal nystagmus that changes direction with head position, with geotropic or apogeotropic patterns.

Epley (preferred first-line for posterior canal) or Semont maneuvers are supported by clinical practice guidelines and systematic reviews (Bhattacharyya 2017; meta-analyses summarized).

Vestibular rehabilitation

Covered when ALL of the following are met

Vestibular rehabilitation criteria: 1) Diagnosis of vestibular hypofunction confirmed by vestibular function testing; 2) Symptoms attributable to vestibular hypofunction have been present for at least one month; 3) Rehabilitation is provided by a physical therapist or occupational therapist as part of a documented therapy plan of care; 4) Usual course is one visit per week for six weeks; up to six additional visits (total 12) are medically necessary only if medical review documents clinically significant improvement; beyond 12 visits without documented improvement is not medically necessary.6 visits; up to 12 with documented improvement

Vestibular rehabilitation is supported by moderate- to strong-quality evidence for unilateral peripheral vestibular dysfunction; use as adjunctive therapy for BPPV per guidelines (McDonnell 2015; Porciuncula 2012; Wegner 2014; Bhattacharyya 2017).

All other uses of particle repositioning maneuvers (the Epley maneuver or the Semont maneuver) or vestibular rehabilitation that do not meet the specific coverage criteria above are not medically necessary. For particle repositioning maneuvers, BPPV is usually in remission within two visits; continuation beyond two visits requires documentation in the medical record justifying further treatment, and if there is no remission after four visits the provider should consider referral back to the attending physician. For vestibular rehabilitation, members with relevant comorbidities may need individualized protocols and must meet the covered criteria to be eligible; failure to meet those criteria renders further therapy not medically necessary.

Dynamic posturography and transtympanic (tympanic) micropressure therapy for the treatment of vestibular disorders are considered investigational and not clinically proven, and therefore are not medically necessary. Requests for these services may be denied on that basis.

Particle repositioning maneuvers for BPPV typically produce remission quickly; remission is usually achieved within two visits. Continued repositioning beyond two visits requires documentation in the medical record justifying ongoing treatment. If symptoms persist after four visits with no remission, clinicians should consider referral back to the attending physician for further evaluation. For vestibular rehabilitation, the usual course is one visit per week for six weeks, with up to six additional visits (total 12) considered medically necessary only if medical review documents clinically significant improvement; additional visits beyond 12 without demonstrated improvement are not medically necessary.

Provider Requirements, Authorization, and Documentation

Prior Authorization

Obtain prior authorization and adhere to vestibular rehab visit limits

Check member benefits and submit a prior authorization when required by the plan; document adherence to visit limits for vestibular rehabilitation (usual course 1 visit/week x 6 weeks; up to 6 additional visits — total 12 — are medically necessary only if medical review documents clinically significant improvement). Vestibular rehabilitation visits beyond 12 without evidence of improvement are not medically necessary.

Verify plan-specific prior authorization requirements before initiating vestibular rehabilitation services.
For vestibular rehabilitation, provide documentation of clinically significant improvement if requesting more than 6 visits (to support up to 12 total visits).
Do not expect coverage for vestibular rehabilitation beyond 12 visits unless improvement is documented on medical review.

Step Therapy

Attempt Epley (or Semont) first for posterior-canal BPPV

Before pursuing alternative nonpharmacologic interventions for posterior-canal BPPV, attempt particle repositioning maneuvers (Epley is identified as first-line; Semont is an effective alternative) and document the attempt and response.

Background and Clinical Context

The vestibular system integrates sensory input from the inner ear, vision, and neck/limb proprioception to maintain balance and spatial orientation. Benign paroxysmal positional vertigo (BPPV) is the most common vestibular disorder and is usually caused by canalithiasis or cupulolithiasis of the semicircular canals, with posterior-canal BPPV being the most frequent presentation. Symptoms are typically brief, position-triggered episodes of vertigo that may resolve spontaneously but are commonly treated with positional particle repositioning maneuvers (for example, the Epley or Semont maneuvers). Vestibular rehabilitation is an adjunctive therapy for confirmed vestibular hypofunction and is provided by a physical or occupational therapist as part of a documented plan of care.

Definitions and Diagnostic Maneuvers

Vertigo — Definition

DefinitionVertigo: a distinct type of dizziness with a sense of rotation, rocking, or the world spinning (illusion of motion).

Typical symptomsMay include imbalance, unsteadiness, blurred or bouncing vision, nausea, hearing changes, and coordination problems.

Etiology noteOften due to inner ear or central processing dysfunction; common causes include head trauma and age-related degeneration of the otolithic membrane.

EpidemiologyIn the U.S., ~1.7% of ambulatory visits record vertigo or dizziness as a chief complaint.

Positive Dix-Hallpike — Definition & Typical Findings

DefinitionPositive Dix-Hallpike: reproduction of vertigo with mixed torsional and vertical nystagmus after the maneuver, typically with a latency period and brief duration (usually <60 seconds).
