R42 is a billable diagnosis code used to specify a medical diagnosis of dizziness and giddiness. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.
The code is linked to some Quality Measures as part of Medicare's Quality Payment Program (QPP). When this code is used as part of a patient's medical record the following Quality Measures might apply: Referral For Otologic Evaluation For Patients With Acute Or Chronic Dizziness.

Clinical Information
- Benign Paroxysmal Positional Vertigo-. idiopathic recurrent vertigo associated with positional nystagmus. it is associated with a vestibular loss without other neurological or auditory signs. unlike in labyrinthitis and vestibular neuronitis, inflammation in the ear is not observed.
- Betahistine-. a histamine analog and h1 receptor agonist that serves as a vasodilator. it is used in meniere disease and in vascular headaches but may exacerbate bronchial asthma and peptic ulcers.
- Dimenhydrinate-. a drug combination that contains diphenhydramine and theophylline. it is used for treating vertigo, motion sickness, and nausea associated with pregnancy.
- Meniere Disease-. a disease of the inner ear (labyrinth) that is characterized by fluctuating sensorineural hearing loss; tinnitus; episodic vertigo; and aural fullness. it is the most common form of endolymphatic hydrops.
- Sulpiride-. a dopamine d2-receptor antagonist. it has been used therapeutically as an antidepressant, antipsychotic, and as a digestive aid. (from merck index, 11th ed)
- Syncope-. a transient loss of consciousness and postural tone caused by diminished blood flow to the brain (i.e., brain ischemia). presyncope refers to the sensation of lightheadedness and loss of strength that precedes a syncopal event or accompanies an incomplete syncope. (from adams et al., principles of neurology, 6th ed, pp367-9)
- Vertigo-. an illusion of movement, either of the external world revolving around the individual or of the individual revolving in space. vertigo may be associated with disorders of the inner ear (ear, inner); vestibular nerve; brainstem; or cerebral cortex. lesions in the temporal lobe and parietal lobe may be associated with focal seizures that may feature vertigo as an ictal manifestation. (from adams et al., principles of neurology, 6th ed, pp300-1)
- Vestibular Neuronitis-. idiopathic inflammation of the vestibular nerve, characterized clinically by the acute or subacute onset of vertigo; nausea; and imbalance. the cochlear nerve is typically spared and hearing loss and tinnitus do not usually occur. symptoms usually resolve over a period of days to weeks. (adams et al., principles of neurology, 6th ed, p304)
- Dizziness-. an imprecise term which may refer to a sense of spatial disorientation, motion of the environment, or lightheadedness.
- Brain Ischemia-. localized reduction of blood flow to brain tissue due to arterial obstruction or systemic hypoperfusion. this frequently occurs in conjunction with brain hypoxia (hypoxia, brain). prolonged ischemia is associated with brain infarction.
- Grade 1 Vertigo, CTCAE|Grade 1 Vertigo-. mild symptoms
- Grade 2 Vertigo, CTCAE|Grade 2 Vertigo-. moderate symptoms; limiting instrumental adl
- Grade 3 Vertigo, CTCAE|Grade 3 Vertigo-. severe symptoms; limiting self care adl
- Vertigo-. a feeling of movement, a sensation as if the external world were revolving around the patient (objective vertigo) or as if he himself were revolving in space (subjective vertigo). vertigo is medically distinct from dizziness, lightheadedness, and unsteadiness.
- Vertigo, CTCAE|Vertigo|Vertigo-. a disorder characterized by a sensation as if the external world were revolving around the patient (objective vertigo) or as if he himself were revolving in space (subjective vertigo).
Tabular List of Diseases and Injuries
The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.
Inclusion Terms
Inclusion TermsThese terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Light-headedness
- Vertigo NOS
Type 1 Excludes
Type 1 ExcludesA type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Quality Payment Program Measures
When code R42 is part of the patient's diagnoses the following Quality Measures apply and affect reimbursement. The objective of Medicare's Quality Measures is to improve patient care by making it more: effective, safe, efficient, patient-centered and equitable.
| Quality Measure | Description | Quality Domain | Measure Type | High Priority | Submission Methods |
|---|---|---|---|---|---|
| Referral for Otologic Evaluation for Patients with Acute or Chronic Dizziness | Percentage of patients aged birth and older referred to a physician (preferably a physician specially trained in disorders of the ear) for an otologic evaluation subsequent to an audiologic evaluation after presenting with acute or chronic dizziness. | Communication and Care Coordination | Process | YES | Claims, Registry |
Patient Education
Dizziness and Vertigo
When you're dizzy, you may feel lightheaded, woozy, or disoriented. If you feel like you or the room are spinning, you have vertigo. These feelings may make you lose your balance.
Dizziness can have many different causes. A sudden drop in blood pressure or being dehydrated can make you dizzy. Many people feel lightheaded if they get up too quickly from sitting or lying down. Certain medicines and problems with your inner ear may cause dizziness. So can motion sickness. Sometimes dizziness can be a symptom of other disorders.
As people get older, they may have more health problems and take more medicines. This makes them more likely to have problems with dizziness and balance.
Dizziness usually gets better by itself or is easily treated. If you are dizzy often, you should see your health care provider to find the cause.

Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
