ICD-10 Code H67.1: Otitis media in diseases classified elsewhere, right ear

Key Takeaways

ICD-10 Code H67.1 describes otitis media in diseases classified elsewhere, right ear – a billable, specific ICD-10-CM code valid for FY2026 HIPAA-covered transactions.

H67.1 is a manifestation code: the underlying disease, such as plasminogen deficiency (E88.02) or a viral disease not elsewhere classified (B00-B34), must always be sequenced first – never use H67.1 as the primary diagnosis, and never pair it with influenza, measles, scarlet fever, or tuberculosis, which carry their own combination codes instead.

Laterality matters: H67.1 is right ear only. Use H67.2 for left ear, H67.3 for bilateral, and H67.9 when the affected side is unspecified.

Practice management software like Pabau helps coders apply correct sequencing rules and keep HIPAA-compliant documentation across clinical workflows.

ICD-10 Code H67.1: definition and billable status

ICD-10 Code H67.1 is a billable, specific ICD-10-CM diagnosis code for otitis media in diseases classified elsewhere, right ear. I

t is valid for FY2026 HIPAA-covered transactions. As the ICD-10 code for otitis media of the right ear tied to an underlying disease, it follows the etiology-manifestation convention, so it can never appear as the principal or primary diagnosis. The underlying condition always leads.

Otitis media coded under H67.1 is never a standalone finding. It develops as a downstream consequence of another disease already documented in the patient record, and that underlying condition is sequenced ahead of H67.1 on the claim.

This reference page covers billable status, code hierarchy, all laterality variants, code-first sequencing requirements, CPT crosswalk, includes and excludes notes, and the most common coding errors coders make with this code. Documentation habits vary by specialty, but the same manifestation-sequencing discipline applies whether the claim involves H67.1 or a non-manifestation right-ear code like H65.31.

H67.1 code description and clinical meaning

The phrase “diseases classified elsewhere” signals the etiology-manifestation relationship. The patient’s ear infection did not arise independently. It developed as a direct consequence of a systemic disease that has its own ICD-10-CM code in a different chapter. The right-ear laterality distinguishes H67.1 from its sibling codes covering the left ear, both ears, and unspecified laterality.

Clinically, otitis media in this context typically presents as middle ear inflammation or fluid accumulation that accompanies an active systemic illness. Influenza, measles, scarlet fever, and tuberculosis are excluded from H67.1, because each already has its own combination code that reports the disease and the ear involvement together.

Plasminogen deficiency and a viral disease not elsewhere classified are the underlying conditions that genuinely require a code-first pairing with H67.1. Accurate structured medical documentation of both the underlying illness and its lateralized ear manifestation is essential before assigning H67.1.

• Otitis media as manifestation: Middle ear inflammation arising as a complication of an underlying systemic disease
• “Diseases classified elsewhere”: The primary condition has its own ICD-10-CM code in a different chapter, such as plasminogen deficiency (E88.02) or a viral disease not elsewhere classified (B00-B34)
• Right ear specificity: H67.1 applies only when the affected ear is documented as the right ear
• Billable status: This is a specific, leaf-level code – no further subdivision is required for submission

H67.1 code hierarchy

H67.1 sits at the leaf level of a four-tier hierarchy within the ICD-10-CM structure. Understanding the parent chain helps coders navigate the tabular list correctly and apply category-level notes that govern all H67.x codes, the same hierarchy logic that governs H66.93 within the neighboring H66 category.

The H65-H75 block covers all diseases of the middle ear and mastoid process. Within it, H67 is the specific category reserved for otitis media that manifests as part of another underlying systemic illness. The category-level note at H67 instructs coders to sequence the underlying disease first – an instruction that flows down to H67.1 and all its siblings.

Laterality variants: H67.1, H67.2, H67.3, and H67.9

ICD-10-CM requires laterality specificity for ear conditions. Selecting the wrong laterality code constitutes a coding error and can trigger a claim denial. The correct code must be driven entirely by documentation – if the physician’s note does not specify which ear is affected, the coder must query for clarification rather than default to H67.9. Using digital intake forms that capture laterality at the point of assessment reduces downstream querying and speeds up claim submission.

When the affected ear is captured at intake, coders rarely have to pause and query for laterality later. That single documented detail is what separates H67.1 from its sibling codes, as the laterality table below lays out.

Which otitis media ICD-10 code should you use?

H67.1 is easy to reach for by mistake. Coders searching for the ICD-10 code for acute otitis media, chronic otitis media, recurrent otitis media, otitis media with effusion, or a general ear infection often land on an H67 code that does not apply. H67.1 is reserved for one situation only: otitis media of the right ear caused by a disease classified elsewhere. When no underlying systemic disease is driving the ear involvement, the correct otitis media ICD-10 code sits in the H65 or H66 category instead.

Assign H67.1 only after the documentation confirms two things: the otitis media affects the right ear, and it is a manifestation of a separately classified underlying disease. For the left ear use H67.2, for both ears use H67.3, and for an undocumented side use H67.9. Every otitis media case without a classified underlying disease belongs in the H65 or H66 categories.

Code-first and sequencing rules for H67.1

H67.1 is a manifestation code. Under the ICD-10-CM Official Guidelines for Coding and Reporting, manifestation codes follow etiology-manifestation sequencing: the code for the underlying cause appears first on the claim, and the manifestation code (H67.1) follows as a secondary diagnosis. This is not optional, and the same etiology-manifestation sequencing applies to H67.3, a related code within the same manifestation category.

A claim that leads with H67.1 as the principal diagnosis will conflict with the code’s built-in instruction and is likely to be rejected by the payer. The CMS ICD-10-CM coding guidelines state that manifestation codes cannot be sequenced as the principal diagnosis.

Underlying conditions to code first

The following are the underlying conditions that genuinely require a code-first pairing with H67.1. Unlike influenza, measles, scarlet fever, and tuberculosis, which each already have their own combination code, these conditions have no dedicated otitis media code of their own:

• Plasminogen deficiency: E88.02 – a genuine “code first” example under the H67 category note, with no dedicated otitis media combination code of its own
• Viral disease NEC (not elsewhere classified): B00-B34 – applies when the causative virus is documented but has no dedicated combination code with otitis media

Coders should never infer the underlying condition. The physician’s documentation must explicitly state the causal relationship between the systemic disease and the otitis media. If the documentation is ambiguous, a clinical query is the appropriate step before coding.

H67.1 coding notes: code first, additional code, and excludes1

Applying code-first, additional-code, and excludes notes incorrectly is a frequent source of claim denials and audit findings. The notes below are reproduced from the official ICD-10-CM tabular list and govern all H67.x codes, including H67.1. Proper use of these notes is also relevant to HIPAA-covered transaction requirements – submitting a code with an Excludes1 conflict on the same claim constitutes a coding compliance risk.

An Excludes1 note means the two conditions cannot coexist according to ICD-10-CM definitions. Reporting H67.1 alongside a combination code for influenza, measles, scarlet fever, or tuberculosis is a coding error and creates audit exposure, since each of those diagnoses already captures the ear involvement within its own code. An Excludes2 note (not applicable here) would indicate the excluded condition is not included in this code but may be reported separately if clinically appropriate.

Documentation requirements for H67.1

Accurate documentation is what separates a clean H67.1 claim from a denial. This code shows up most often in general practice and functional medicine settings, where the underlying systemic disease driving the ear involvement is already being tracked.

The physician’s note must contain three elements before a coder can assign H67.1 with confidence. Missing any one of them creates an incomplete record that cannot support billing.

• Right-ear laterality: the clinician must explicitly document that the right ear is affected. “Otitis media” alone, without laterality, cannot support H67.1.
• Named underlying disease: the diagnosis must be stated clearly, for example “plasminogen deficiency with right-ear otitis media.” Vague terms such as “infection” or “systemic illness” are not enough.
• Documented causal link: the note must connect the ear finding to the underlying disease, using language such as “secondary to” or “as a manifestation of.”

If the note also documents a perforated eardrum, report an additional code from the H72.- range alongside H67.1 to capture that finding separately.

Related CPT codes and billing crosswalk

H67.1 pairs with procedure codes that reflect the clinical visit type and any active treatment. The CPT codes below are commonly submitted alongside this diagnosis code. They are representative of clinical practice – coders must verify pairings against the specific payer’s policies, as acceptance is not guaranteed. Pabau’s claims management software supports crosswalk verification and reduces the manual effort of matching ICD-10 diagnosis codes to appropriate procedure codes at the point of submission.

Automating submission keeps the diagnosis-to-procedure link intact from the exam room through to the payer. The CPT codes most commonly paired with H67.1 are summarized below.

For the most current reimbursement amounts and payment rates, consult the CMS fee schedule lookup. Rates vary by geographic pricing locality and payer contract terms.

Common coding errors and how to avoid them

H67.1 generates a predictable set of coding errors that billing teams encounter regularly. Most of them trace back to three root causes: misunderstanding the manifestation convention, ignoring laterality documentation, and submitting without a paired etiology code.

ntegrating compliance management tools into the pre-submission workflow catches these errors before they reach the payer. And documentation in patient records that explicitly states the causal relationship between the underlying disease and the ear finding is the first line of defense.

• Using H67.1 as the primary diagnosis: The code’s built-in instruction prohibits this. Any claim where H67.1 appears in the principal diagnosis position will conflict with the etiology-manifestation rule and face denial. The underlying disease code must always lead.
• Wrong laterality selection: H67.1 is right ear only. If the physician documents bilateral otitis media as a complication of plasminogen deficiency, H67.3 applies – not two separate submissions of H67.1 and H67.2. Documentation drives the code, not clinical assumption.
• Missing the etiology code entirely: Submitting H67.1 without a companion underlying disease code, such as plasminogen deficiency (E88.02) or a viral disease not elsewhere classified (B00-B34), leaves the claim incomplete. Pairing H67.1 with an influenza, measles, scarlet fever, or tuberculosis code is not a fix, either – it triggers an Excludes1 conflict, since those diseases already report the ear involvement within their own combination code.
• Confusing H67.1 with H65.x or H66.x: H65 covers nonsuppurative otitis media, H66 covers suppurative and unspecified otitis media. These are stand-alone diagnoses, not manifestation codes. If the otitis media is not caused by an underlying classified disease, H67.1 is the wrong category entirely.
• Defaulting to H67.9 without querying: If the affected ear is not documented, the coder’s job is to query the provider – not to default to the unspecified code to avoid a delay. Specificity drives reimbursement accuracy and audit defensibility.

The CDC/NCHS ICD-10-CM web tool remains the definitive official source for verifying code validity against the current fiscal year tabular list, including the annual updates and addenda published by CMS and NCHS.

Conclusion

H67.1 catches coders off guard because it looks like a straightforward ear code. The billable status and clear description create a false sense of simplicity. The complexity sits in the sequencing requirement, the laterality discipline, and the Excludes1 note, all of which must be checked every time before submission.

Pabau’s practice management software brings diagnostic coding context into the clinical workflow so that coders, clinicians, and billing staff work from the same documented record. Fewer queries, fewer denials, faster reimbursement.
