ICD-10 Codes for Vertigo: A Medical Coder’s Guide
Vertigo affects 5% of adults annually, making accurate ICD-10 coding essential for claims accuracy and reimbursement. Yet, mismatched codes like H81.10 (peripheral vertigo) vs. R42 (dizziness) trigger 25% of denials in ENT and neurology practices. In this guide, I’ll decode the top 10 ICD-10 codes for vertigo, 2024 updates, and documentation hacks to ensure clean claims.
Why Precision Matters in Vertigo Coding
Incorrect codes lead to:
- Denials for “mismatched symptoms” (e.g., linking vertigo to migraine without G43.821).
- Compliance Alert: Avoid frequent use of unspecified codes like H81.10, as it may raise red flags during audits.
- Lost revenue due to delayed appeals.
Pro Tip: Always include documentation for laterality (left or right ear) and any underlying conditions such as Benign Paroxysmal Positional Vertigo (BPPV) or Meniere’s disease.
Top 10 ICD-10 Codes for Vertigo (+ Clinical Scenarios)
- H81.10 – Unspecified Peripheral Vertigo
- Use Case: Vertigo linked to inner ear issues, no laterality specified.
- Red Flag: Medicare may deny without audiometric testing.
- H81.11 – Peripheral Vertigo, Right Ear
- Key Detail: Requires provider documentation of affected ear.
- H81.12 – Peripheral Vertigo, Left Ear
- Example: “Left-sided vertigo with nystagmus post-head injury.”
- R42 – Dizziness and Giddiness
- Use Case: Non-specific dizziness (not true vertigo).
- Avoid: Confusing with H81.10 (peripheral vertigo).
- H81.41 – Vertigo with Tinnitus
- Link to Meniere’s: Pair with H81.0- series if diagnosed.
- G43.821 – Vestibular Migraine with Vertigo
- Critical: Document headache history (e.g., pulsating pain, photophobia).
- H81.3 – Central Vertigo
- Cause: Brainstem lesions, MS, or stroke.
- Documentation Must Include: Neurological findings (e.g., MRI results).
- R11.2 – Nausea with Vertigo
- Combo Coding: Use with H81.10 or G43.821.
- Z01.810 – Encounter for Hearing Exam with Vertigo
- Use Case: Vertigo under evaluation (e.g., ruling out Meniere’s).
- R51.9 – Headache with Vertigo (Unspecified)
- Avoid: Use only if migraine isn’t confirmed.
ICD-10 Updates for Vertigo
- Laterality Requirements: Unspecified codes (H81.10) require clinical justification for Medicare.
- Combination Codes: Use H81.4- series for vertigo with hearing loss or tinnitus.
- Meniere’s Specificity: New guidance to code H81.01-H81.03 with stage (e.g., cochlear vs. vestibular).
3 Common Coding Mistakes (and Fixes)
- Overusing “Unspecified” Codes
- Fix: Query providers for laterality or cause (e.g., BPPV, labyrinthitis).
- Mixing Dizziness (R42) and Vertigo (H81.10)
- Fix: Clarify symptoms—vertigo = spinning; dizziness = lightheadedness.
- Ignoring Migraine Links
- Fix: When documenting vestibular migraines, use G43.821, supported by clear clinical notes..
Final Thought
Accurate vertigo coding isn’t just clinical—it’s financial. A single error (e.g., using R42 instead of H81.11) can delay payments by 30+ days and trigger audits. By training providers on specificity (e.g., “right ear BPPV”) and leveraging EHR tools for code validation, billing teams can:
- Slash denials by 40%+.
- Speed up A/R cycles.
- Ensure compliance with 2024 CMS guidelines.

Frequently Asked Questions (FAQs)
Use H81.10 (peripheral vertigo) + R11.2 (nausea).
G43.821 (vestibular migraine) + headache specifics (e.g., G43.909 for chronic migraine).
H81.3 (central vertigo) + underlying cause (e.g., G46.4 for cerebellar stroke).
Yes, but auditors may request caloric testing or audiograms.
