    ICD-10-CM Code For Nausea And Vomiting: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group R11 includes diagnoses for nausea, vomiting, and related gastrointestinal symptomatic presentations, covering isolated nausea, isolated vomiting, and combined nausea with vomiting due to various causes. These ICD-10-CM diagnosis codes are used to document patient encounters when these symptoms are present, capturing clinical severity, symptom persistence, and impact on care decisions. Accurate coding within the ICD-10-CM R11 group supports proper claim adjudication and complete clinical documentation for appropriate reimbursement.

    ICD-10-CM R11: Nausea And Vomiting Overview

    The ICD-10-CM R11 code group represents diagnoses for nausea and vomiting, signs and symptoms associated with the digestive system. These codes target gastrointestinal symptomatology rather than specific underlying diseases and are used across outpatient and inpatient settings. Accurate coding matters because it supports clinical documentation, appropriate claim processing, and reflects the complexity of patient care.

    When to Use

    Use a code from this group when a patient visit is for evaluation, treatment, or documentation of nausea and/or vomiting without a documented underlying cause or when the symptoms are the primary focus of care. If an underlying disease or cause is identified and documented, code(s) for that condition should be assigned in addition to or instead of the R11 code as appropriate.

    Typical Clinical Scenarios

    • An adult presents to the emergency department with abrupt onset of persistent vomiting for the past 12 hours after an episode of suspected food poisoning. The patient is dehydrated, has orthostatic tachycardia, and requires intravenous fluids and antiemetic therapy; no clear alternative diagnosis is identified on initial evaluation, so an acute unspecified vomiting code is assigned. Typical codes: R11.10, R11.0
    • An elderly patient with advanced Parkinson disease reports recurrent episodes of nausea and vomiting over several weeks related to dopaminergic medication effects and gastroparesis; symptoms are intermittent but recurrent and are managed in the outpatient neurology clinic with medication adjustments. A code is used to capture the ongoing recurrent vomiting and to document it as a chronic symptom complicating care. Typical codes: R11.11, R11.12
    • A pregnant woman in her first trimester has severe, persistent nausea and vomiting causing weight loss and electrolyte imbalance; she is seen in obstetrics for assessment and possible hospitalization for severe morning sickness (hyperemesis gravidarum ruled out on initial evaluation). The encounter is coded to reflect vomiting associated with pregnancy-related nausea when documenting severity and treatment needs. Typical codes: R11.2, R11.13
