Vertiginous syndromes in diseases classd elswhr, unsp ear

This code represents a diagnosis of vertigo or dizziness that is a symptom of another underlying disease process, when the specific ear affected is not documented. It indicates a secondary vertiginous syndrome where the primary condition is classified elsewhere in the ICD-10-CM system.

Use this code when a patient presents with vertigo or dizziness clearly attributed to another systemic or neurological condition, and the medical record does not specify laterality (left, right, or bilateral ear involvement). This code is appropriate when the primary diagnosis for the underlying disease has already been established and coded.

• Always sequence this code as a secondary diagnosis, following the code for the underlying condition causing the vertiginous syndrome.
• Avoid using this code if a more specific code for the type of vertigo (e.g., peripheral, central) or the affected ear is documented.
• Query the provider for clarification on laterality or a more specific diagnosis if possible, to avoid using an unspecified code.
