ICD-10 Code H82.2: Vertiginous syndromes, left ear

Key Takeaways

ICD-10 Code H82.2 is a billable diagnosis code for vertiginous syndromes in diseases classified elsewhere, specifically the left ear

Always assign an additional code for the underlying condition – Meniere’s disease (H81.0x) or labyrinthitis (H83.0x) – when billing H82.2

Excludes1 applies to epidemic vertigo (A88.1): never assign H82.2 when epidemic vertigo is the documented cause

Pabau’s claims management software flags dual-coding requirements at point of entry, helping reduce denials for manifestation codes like H82.2

ICD-10 Code H82.2 identifies vertiginous syndromes in diseases classified elsewhere, left ear. It’s a manifestation code, so it’s only ever assigned alongside the underlying disease code — typically Meniere’s disease or labyrinthitis — that’s producing the vertigo. Missing either code triggers claim denials, which is why accurate medical coding depends on capturing both together.

This guide covers H82.2’s billable status, the Code First convention, laterality siblings, dual-coding requirements, excludes notes, documentation standards, and how to differentiate it from related vertigo codes.

ICD-10 Code H82.2: definition and billable status

ICD-10 Code H82.2 identifies vertiginous syndromes in diseases classified elsewhere, left ear. It is a billable/specific ICD-10-CM code — a complete 4-character code that can be used directly for reimbursement purposes, with no additional 5th or 6th character required. The CDC/NCHS ICD-10-CM web tool confirms the 2026 edition of H82.2 became effective on October 1, 2025.

The phrase “diseases classified elsewhere” is the critical distinction. H82.2 is a manifestation code: it describes a symptom (vertigo) that arises as part of another, separately classified disease. The underlying disease must always be coded first. Coders who assign H82.2 alone, without the companion etiology code, will routinely see claim rejections.

Code First convention and instructional notes for H82.2

The ICD-10-CM Tabular List does not include any Applicable To annotations under H82.2. Per the CDC/NCHS ICD-10-CM web tool, the only official instructional notes attached to H82.2 are inherited from its parent category, H82: a “Code First: underlying disease” note and a Type 1 Excludes note for epidemic vertigo (A88.1). There is no separate annotation naming specific etiologies.

The Code First convention means H82.2 can never be the lead diagnosis on a claim: whatever disease is producing the left-ear vertiginous syndrome must be coded first, with H82.2 following as the manifestation code. Two of the most common qualifying underlying diseases are:

• Meniere’s disease, left ear (H81.02) – when a confirmed left-ear presentation of Meniere’s disease produces vertiginous symptoms, H82.2 captures the vertigo manifestation. H81.02 is coded first as the etiology.
• Labyrinthitis, left ear (H83.02) – when bacterial or viral labyrinthitis of the left inner ear causes vertigo, H83.02 is sequenced first and H82.2 describes the resulting vertiginous syndrome.

These are clinical examples of underlying diseases that qualify for the Code First pairing, not an exhaustive or officially annotated list. Any confirmed disease classified elsewhere that produces left-ear vertiginous syndrome can pair with H82.2, provided it is separately coded first.

Other manifestation codes, like D77, follow this same convention: the etiology comes first in the coding sequence, the manifestation follows.

H82.2 in the H82 code family: laterality breakdown

H82 is the non-billable parent code. It requires a 4th character to specify laterality. Assigning H82 alone will result in a payer rejection because it is not billable at the 3-character level. Select the correct sibling based on which ear is documented in the clinical record.

Documentation rule: audiologists and ENT clinicians should specify laterality in every encounter note. Selecting H82.9 (unspecified) is valid only when the clinical record genuinely does not document which ear is affected. Coders should query the provider before defaulting to unspecified, because payers scrutinize non-specific codes during audits. Good clinical record documentation reduces the need to use unspecified codes.

Using ICD-10 Code H82.2 correctly: additional code requirements

Under ICD-10-CM coding conventions, H82.2 carries a “Code First: underlying disease” instruction. This etiology/manifestation convention requires coders to always assign both the underlying disease code and H82.2 together — H82.2 is never submitted alone. Claims that carry H82.2 without an etiology code are clinically incomplete and will typically be denied.

Common dual-coding pairs:

• Meniere’s disease, left ear (H81.02) + H82.2 – when left-ear Meniere’s disease produces vertiginous symptoms. H81.02 is the etiology; H82.2 is the manifestation.
• Labyrinthitis (H83.02) + H82.2 – when left-ear otogenic labyrinthitis causes secondary vertigo.
• Other otological diagnoses classified elsewhere that produce left-ear vertigo may also pair with H82.2, provided the underlying condition is separately coded.

Sequencing matters too. Per the AAPC ICD-10-CM coding guidance, etiology/manifestation pairs follow a strict rule: list the etiology code first, then the manifestation code. Reversing the sequence can trigger editing software flags even when both codes are correct. Claims management software that prompts dual-code entry at the point of coding prevents this sequencing error before submission.

Excludes notes and coding boundaries

The H82 category carries one Excludes1 note that applies to all H82.x sibling codes, including ICD-10 Code H82.2:

• Excludes1: epidemic vertigo (A88.1) – epidemic vertigo is an infectious cause of vertigo with its own code in Chapter 1 (Certain infectious and parasitic diseases). Excludes1 means these two codes are mutually exclusive: they cannot be assigned together on the same encounter. When epidemic vertigo is the documented cause, assign A88.1, not H82.2.

There is no Excludes2 note directly on H82.2. Meniere’s disease codes (H81.0x) are not excluded from use with H82.2 — they are the intended etiology pair. The distinction matters because Meniere’s disease is separately classified in block H81 (disorders of vestibular function).

H82.2 captures the vertigo manifestation of that disease, while H81.0x captures the disease itself. Both apply simultaneously. The same etiology/manifestation convention shows up in E84.8, another code that pairs a symptom with its underlying disease across chapters.

H82.2 vs related vertigo diagnosis codes

Several ICD-10-CM codes describe vertigo or inner-ear dizziness. The table below maps the most commonly confused codes, helping coders select the correct one based on clinical context. Per the CDC/NCHS ICD-10-CM web tool, each code occupies a distinct clinical category within the US-specific ICD-10-CM tabular list.

Common mistake: assigning R42 (dizziness) alongside H82.2 when H82.2 already describes the vestibular symptom. R42 is a symptom code – use it only when no confirmed diagnosis exists. Once a vertiginous syndrome secondary to a classified disease is documented, H82.2 replaces R42. ENT and audiology practices using specialist EMR software can configure code libraries to surface the correct pairing automatically.

Documentation requirements for H82.2

Payers auditing H82.2 claims look for four elements in the clinical record. Missing any one of them can trigger denial or post-payment recoupment.

1. Laterality – the note must state “left ear” explicitly. “Bilateral” or “right ear” invalidates H82.2 as the code choice.
2. Confirmed underlying diagnosis – the physician or clinician must document the diagnosed disease (Meniere’s disease, labyrinthitis, or another classified condition) that is causing the vertigo. A working diagnosis or “rule-out” is insufficient.
3. Symptom link – the record should connect the vertigo to the underlying condition, not treat them as unrelated findings.
4. Visit type – whether the encounter is an initial evaluation, follow-up, or procedure visit affects which additional E/M or procedure codes accompany H82.2. Document encounter type clearly.

Practices using digital intake forms and structured encounter templates can pre-populate laterality and confirm diagnosis fields, so nothing is missing by the time the note closes. Audiology and speech therapy practices handling vestibular referrals benefit most from this setup, since laterality gets captured once and reused across every downstream code.

EHR integration between clinical documentation and billing workflows is where most H82.2 errors originate: the coder receives a note that says “left ear vertigo” without a confirmed etiology code, then must query the clinician, delaying the claim cycle.

ICD-10 Code H82.2 validity and update history

H82.2 has been a valid ICD-10-CM code since the ICD-10-CM system came into US use. The 2026 edition, effective October 1, 2025, carries no structural changes to H82.2: the code description, Code First instructional note, Excludes1 note, and laterality family remain unchanged from prior fiscal years.

Coders who verified H82.2 in FY2025 do not need to relearn the code for FY2026. They do need to confirm their billing software uses the FY2026 code files, which became active on October 1, 2025.

How practice management software supports H82.2 coding accuracy

The single most common billing failure with H82.2 is submitting the manifestation code without the etiology. This happens because clinical documentation and billing are often handled by different team members, and the handoff breaks down. Integrated claims management software prevents that breakdown by enforcing dual-code pairing before submission.

Practices can configure claim scrubbing rules that flag any encounter with H82.2 submitted without a companion H81.x or H83.x code. Billing-integrated practice management systems offer this as a standard feature.

The same workflow catches sequencing errors. If H82.2 appears as the primary code with H81.02 secondary, the scrubber can alert the coder to reverse the order before the claim reaches the clearinghouse.

For ENT and audiology practices handling a high volume of vestibular disorders, structured encounter templates with mandatory laterality and diagnosis fields catch missing information upstream. When the clinician completes a structured note, the required fields for H82.2 coding — laterality, confirmed diagnosis, symptom link — are captured at the time of care instead of being reconstructed during coding.

Practices building these workflows use compliance-first documentation approaches that protect both the patient record and the revenue cycle. The same dual-coding convention appears in H67.9, another classified-elsewhere ear code, across multiple ICD-10-CM chapters wherever a manifestation code is in play.

Conclusion

ICD-10 Code H82.2 is a straightforward billable code with one non-negotiable rule: it never stands alone. Every H82.2 claim requires a paired etiology code, correct laterality documentation, and awareness of the Excludes1 boundary with epidemic vertigo (A88.1). Coders who build those checks into their pre-submission workflow will rarely see H82.2-related denials.

Pabau’s claims management workflow can be configured to enforce dual-code pairing and laterality checks before H82.2 claims reach the clearinghouse. To see how it fits an ENT or audiology practice, book a demo.
