Dizziness and giddiness are common yet complex to code due to overlapping symptoms and varying underlying causes. As a medical billing expert with 12+ years in coding compliance, I’ll break down ICD-10 guidelines for dizziness, including R42, peripheral vertigo, medication triggers, and denial-proof documentation.
ICD-10 Code R42 is designated for the symptoms of dizziness and giddiness. These sensations can range from light-headedness to the feeling of spinning, known as vertigo. This code applies when a patient experiences dizziness, but no specific underlying condition has been identified.
ICD-10-CM Code R42 is the default for dizziness when the cause is unspecified. However, coders often misuse it, leading to denials. Here’s how to apply it correctly:
The ICD 10 R42 code is billable and is often utilized by healthcare providers in primary care, neurology, and otolaryngology.
The symptoms related to the R42 diagnosis code include various forms of unsteadiness, which can lead to:
Proper use of this code requires thorough documentation by healthcare providers to substantiate the patient’s symptoms. Documentation should indicate that the patient’s dizziness or giddiness lacks a specific etiology, ensuring claim accuracy and supporting medical billing.

ICD-10 Code R42 is essential for billing cases involving dizziness and giddiness when no specific diagnosis has been established. Accurate documentation of symptoms, adherence to coding guidelines, and use of advanced EHR solutions like CuresMB can aid providers in managing claims efficiently and minimizing denials. By understanding and applying best practices in ICD-10 coding, healthcare providers ensure compliant billing while maintaining optimal patient care.
ICD-10 Code R42 is used to document and bill for a broad diagnosis of dizziness and giddiness. It covers symptoms like lightheadedness, a spinning sensation, or balance issues that don’t have a more specific underlying cause yet. It’s important to pair this code with a thorough clinical evaluation, especially if symptoms are recurring.
Not always. While R42 is a general catch-all for dizziness, providers should try to identify more specific causes when possible, like vertigo, hypotension, or inner ear conditions. If no clear diagnosis is determined, R42 remains a valid and acceptable code for billing purposes.
The ICD-10 code for chronic dizziness may still fall under R42, but documentation should clearly indicate the long-term or recurring nature of the symptom. Some payers or EMRs may require adding a note for chronicity or using additional codes that support underlying causes—like vestibular disorders (H81 series).
R42 can be billed for office visits, evaluations, or diagnostic testing related to dizziness. However, because it’s considered a symptom code, insurers often expect further workup. If you’re a provider or billing team, use R42 wisely, and document everything clearly to support the medical necessity.
Yes, but cautiously. Dizziness in seniors can result from multiple causes like low blood pressure, medication effects, or neurological conditions. While ICD-10 Code R42 may still apply, it’s best to investigate and, if possible, document a more specific cause to avoid unnecessary claim denials or audit flags.
